Tubular Tyres: Tape Or Glue? | The GCN Tech Clinic

[@waynosfotos]

As to glue vs tape for tubulars, the tape is supposed to use a few more watts, apparently, but I run tape as I ride my tubulars everywhere. The problem with glue is, it hardens over time. Especially if not ridden like race wheels (in the off season). Then they get out the tubulars next year, and the glue has hardened (doesn’t flex anymore) and lets go off the rim due to the riding action. Tape does the opposite, the longer it stays on the more it gets spread and sticks. It never goes hard. So glue if you want to race, but change every season, or tape for general or long term use.

[@bicyclist2]

Thank you very much for this valuable information. This is exactly what I came here to find out. I just got my first pair of Magic tubular wheels. I've never used tubular before.

[@marktezmo2918]

I've heard an idea that the glue is more safe when downhill,isn't it?

[@hedleykerr3564]

I ride tubulars and one time I actually fitted a tubular tyre on a clincher rim when a friend of mine slashed his clincher tyre! It worked to get him home the next 30k!

[@laod7192]

This is exactly what we used to do before mounting new tubular tires. Instead of pumping up a tubular and let it sit for a day to stretch, we fit them on clincher rims and ride them. This can be a very good trick.

About lubing the chain: do not apply lube but wax. Wax hardly attracts dirt and it has the lowest friction of all ‘lubes’.

[@JeffreyWilliams-dr7qe]

Glue 3M Fast tack if still around. Designed for auto trim work. Tufo tape for years. Great tires from them as well.

[@justinsparhawk6755]

I used tubuless tires on standard road wheels for road and ‘cross for several years. I never had a problem with safety over very many miles. I now have some American Classic wheels that are tubeless specific. I can tell you the tires are much more firmly seated into the tubeless specific rim. On the other hand I also have tubeless 700X28C tires on my Zipp 404’s. I don’t have any concerns leaning into any corner at any speed. And they are sooo nice on the rough roads.

[@ariellevin3008]

I ride the track and just mounted some Vittoria Pista Control on my Carbon disc. I used mastic glue this time and found that, after two coats on both the rim and the tire, the glue never got tacky. I let both sit over night with the final coats applied before mounting. Should they have felt tacky upon application?

[@frankwilliams977]

Which wheel roles better? a Giant SLR-1 Disc WheelSystem or a Mavic KSYRIUM PRO CARBON SL C DISC?

[@DarrenJohnson1973]

For chain skipping across the cassette also check for chain stretch, 1st indication of chain stretch is missed shifts

[@naf2579]

Been using Carogna tape for a couple years now and will never glue again. Super strong bond, no issues.

[@thomasvmanning]

If you don't mind the oily residue, car lube thinned with mineral spirits is a very effective chain lube. Use it with a little oiler to avoid the mess, roll in into the chain well and then wipe off excess. It's a hell of a lot cheaper than any wet lube you can buy.

[@8rk]

Been using tape for 3 years. They have come a long way and I'd argue that they are (two brands I love) as safe as glue if not safer nowadays. With the benefit of leaving 0 mess behind and being able to take off old tires, install new ones and ride within 30 mins (as opposed to a few days). I JUST took an old tire off of my tubular wheels cause they were squared off. They were bound REALLY strong on the wheels and took a lot of effort. That should tell you how safe they are. BTW 2 brands I prefer are Caden Wheels tape (from australia) and effetto mariposa carogna. In that order.

[@Armurp01]

what do you use to carry a spare tire?

[@8rk]

@@Armurp01 My spare tire is Tufo Elite Jet (21 mm I think). While I would never ride that regularly, it's fine as a spare tire to complete your ride and get you home! The advantage is they fold VERY compact. Almost as small as an inner tube. So it fits my small saddle bag. One tip though instead of a square shaped saddle bag you need one that needs to be skinnier / longer. But a small one will definitely do the trick. Still fits my Co2 / inflater and multitool as well!

[@Armurp01]

@@8rk thanks for the tip.....when you do replace the tire, is your tape still on there or does that get removed too when putting on the spare.....just had a blowout on a tubular and I need ideas for a spare otherwise I'm switching to clinchers lol.... Haven't had the best of luck with tubulars since getting into this as of recent but I like how they ride and the easiness of using tape.

[@8rk]

​@@Armurp01 when you remove the tire, tape is stuck onto the tire most of the time. the "tire side" of the tapes (at least the two i mentioned) are designed to be stronger than the rim side. With the Caden tape I've had it stuck to rim too but it really doesn't matter. With use of a heat gun or hair dryer, removing the tape is SUPER easy and clean. Almost 0 residue so your rim looks brand new. On the road, if the tape is left stuck on the rim, it doesn't matter. Even better actually for added protection. If it does go off with the tire, you just install the spare with no tape and take it easy on descends / turns. Go 75% the speed you normally would. the tire pressure is 75% of what's holding the tire tight on the rim. Tape / glue is to do the rest and secure it. I definitely prefer the feel and weight of tubular setup. I use Veloflex tires (25 or 28mm ProTour (not the race version)) They are light, very grippy and the last time I had a flat was in 2017 I believe!

[@Armurp01]

@@8rk thank you for the insight....going to order that type of tire for a spare (Tufo elite jet)

[@GaryDunn808]

Question about tubeless tires. What to carry if anything for repairs? Long rides and triathlon races. I am thinking a small hand pump, but i a 40K time trial a puncture bad enough to require more air may well mean the day is done, so why carry extra weight?

[@kahrpistols]

Regarding the disc/rim brake combo, you could run a cable disc up front and a rim in the back & that would eliminate your concerns about differing lever feeling. Granted, cable discs aren't as good as hydraulic, but if one really wanted to run this then that's one way they could.

[@Tubercyclosis]

Stages Ultegra v. 105 crank arm: I believe the Ultegra arm is lighter than the 105, so the crank would not be balanced after mixing. Does that matter? It might be a PITA when working on the bike on a stand if the crank always rotates so the right arm is down. Also, why spend money on a Stages one-sider when the price of complete (both sides) PMs are not much higher? My experience with Stages is that they're not as accurate as other PMs and the accuracy is futher complicated by left-right imbalances (nobody is exactly 50-50 all the time).

[@firstname7780]

Carogna Tape the best thing that happened for tubulars. Resists hundreds of deg C, easy to remove pulling ( not side to side rolling) no cleanup, and 5 min to apply. 24 hr for best cure... awesome

[@alexanderwendelbo1447]

Hi all. Q: How hard should I tighten my cleats? I saw a vid with Si and he used a 5nm key, but that’s just not enough for the clear to stay in place in the pedal. Shoes are Bontrager XXX LE and pedals are Shimano Tiagra.

[@maddogmtb]

I’ve run tubeless on my CX bike and my mountain bikes using both tubeless and even non-tubeless tyres and non-tubeless rims many times without any issues. They tend to require much more sealant and can be a pain to seat without a compressor but you can get them to work effectively. I’ve never used proper rim tape either, I use Gorilla tape which works fine. I did try a non-tubeless tyre on a tubeless road rim once but that specific combination wasn’t overly successful, they would go flat overnight more often than not.

[@bicyclist2]

At about 4:00 you mentioned there was no problems with tubulars. I have the 03' TdF on DVD. And in a mountain stage Beloki has his tire come off his rim in a decent. And Lance behind him goes into the grass to avoid hitting him. Check it out. Thanks.

[@eosme]

i was hoping there would be a clear answer on the tape vs glue debate. i am using glue now, but i find cleaning and removing old glue from carbon rim to be a pain in the arse. so i'm thinking to use tufo tape. question is, for my veloflex that has some left over glue on there, would it be ok to use tape over it? or would i need to remove the old glue from the base tape before mounting with tape? the rim has been cleaned off.. took me 3 days...argh

[@billorr99]

Question on tubular repair... I use valve extenders on Campy wheels and I’m afraid an over aggressive tightening of the extender has caused the primary presto valve to work loose from the tire. Catastrophic flat unable to be repaired on the road - has to call for a car to get home. Sealant doesn’t help. Can this be repaired? Or am I in the market for a replacement tire... thanks for any help.

[@MrJgibo1]

Question for you. My Canyon Inflite CF SLX 9 is nice and quiet except when in the 3rd smallest cassette. My local bike shop adjusted it one but didn't seem to last. Any suggestions.

[@DeanGrove]

So I'm new to tubulars, I don't ride outside too much. Only on race days, are those sealants from TUFO etc a solution if I'd get a smaller puncture during a Triathlon/Race ? With tubulars I obviously can't switch as fast as if I'd have clinchers.

[@JamesBoz]

My shifting has become hard. I may have internally crossed cables when replacing. Is there an easy way to see if this is so? They're a nightmare to re-route!

[@hawkeye5035]

Love the new channel! Question on tubeless maintenance... what is required at regular intervals to keep my road/ cx tubeless operating flawlessly? I flatted not long ago after 7-8 months, and the sealant was dried up... how often should it be topped off/ changed altogether? Anything else required?

[@indiebikes]

With Stages Shimano power meters, the thing to remember is that even though the Hollowtech II interface is the same on 105/Ultegra/Dura Ace, the drive side crank arms are stiffer as you go up the range, so the strain gauge on the left arm might not match the actual power of the right arm. But having said that, does it really matter? I'd be more bothered that the arms don't match (OCD alert)

[@someguy9520]

well, my old sora short cage mech works with a 11-34t sram 9spd mtb cassette. sure the 34t cog flexes the cage quite a lot but the chain works just fine and it didn't fall off or get stuck between the spokes and casette

Good tip on the heli-coil

[@jasonmolenda]

re. mixing & matching Stages left-hand PM crankarm with a different crankset. Broke an XT crankset by putting an XTR stages left-hand crank arm on it. XTR crankarm was like 12mm skinnier than the XT/SLX crankarm. The shimano spindle has grooves cut into it where the crankarm clamps; I had something like 12mm of these grooves with nothing clamped on. (I was also having to do some weird shimming of the BB to make the crankset not wiggle - wish I'd looked more closely when I was doing that) I think I made it about a thousand km before the crank spindle cracked in half while standing on the pedals. Anyway, if you do mix & match different shimano crank arms, make sure they're really the same width before you use intermix.

[@monnkeey]

A helicoil is a great option. I had used couple of helicoils both in my nds crank arm and the rear derailleur guide pulley axle. However, I can't forget the feeling when I incorrectly set my torque wrench when tightening the pedal. The crank was a right-out- of-the-box Quarq power meter. Eventually I replaced it with a new one which SRAM exchanged for free after I wrote an email. Great great company !!!

[@1989srjones]

how can I check if my bike will have enough clearance for 28mm wide tyres before actually buying (or borrowing) a pair and fitting them? Currently use 25mm but was thinking of trying out 28mm when I next replace them

[@glennreed9764]

Bicycle Quarterly says you should have 3mm minimum clearance. If you have at least 4.5mm now, the 28s should fit fine. The main problem is that claimed widths aren't trustworthy. Less risky if you stick to the same tire brand, but it may still take some trial & error. Here's the full story: janheine.wordpress.com/2013/03/12/how-wide-a-tire-can-i-run/

[@sudduthjonathan]

Go ask your local bike shop to try on some tires. If you’re willing to buy them there, they should able to help. I am thinking about putting some gravel tires on my old wheels...they said to bring everything in and then we’ll see how large I can go on the wheels and frame. Even if you spend a little more this first time, at least you’ll know it’s right and then can order cheaper ones next time.

[@U20101954]

i am using sram red 10 speed front and rear mech with sram red 11 speed shifter, working flawlessly. well you will need to expand the front mech cage with a 0.5mm spacer to get rid of chain rub when you are using the big-big/ small-small combo. and for loose bb bearing, dont waste money on anything else, get yourself an enduro torqtite cup and you are good to go.

Regarding the rim vs disc brake hood comparison, they'll only be / feel different if one is cable and the other is hydraulic. There are cable disc brakes and hydraulic rim brakes available, so you could match the set of brifters.

A tech question on disk brakes. I've seen a number of comments online and SM about a potential problem when taking a disk brake equipped bike on a plane. Some people [inc a pro-mechanic] suggest some brands of brakes need bleeding after a flight! Is this true? If so what brands? Does this explain the relative lack of pros riding with disk brakes still e.g. Trek suggested they were going to focus on disk brakes this year but most of the pro riders are still using callipers?

[@steamroller72]

I have a Trek Madone with BB90 for the bearing question. That scenario is quite frequent and my bearings can be removed and pressed in quite easily. I have not noticed any issues as I just replaced the OE bearings with Enduro Ceramics and they fit somewhat loosely as well. Spins like a top...

[@jamesalanjob]

The bb90 bearings should be snug in the frame. They have an issue of letting water in on the NDS. When the bearing gets corroded it starts turning in the frame damaging the bb shell. So trek came up with the v2 bearing to fit the woren shell. Personally i check mine every few months and install them with loctite assembly compound.

#askGCNtech Hi Jon. Really enjoying the tech channel with so much more tech focused content than before on the GCN channel. I recently bought an FSA Powerbox which is based on BB386EVO. My bike has a BB30, but came with an FSA SL-K Light (BB386EVO) with the spacers etc. I fitted the Powerbox with the spacers in exactly the same order that I took them off the SL-K, but now I am getting an annoying clicking sound in the small ring with the 2 or 3 cogs at the top of the cassette.

@benjamdm I second checking your hanger alignment. I've had this problem a few times and if everything else seems right, every time the hanger has been off some. I've found this to be when I was having trouble in the middle of the cassette, recheck the limit screws after adjusting the hanger too.

If you actually want to use a disc brake on the front and a rim brake on the rear, SRAM makes hydraulic rim brakes that can be used with the same levers on both brakes.

#askgcntech - I have a couple of 5mm cuts on the crown of a "newish" GP4000 II tyre. I have tried the superglue method but the cuts opened up again on the next ride. Is there an alternative method to save the tyre or is it a new tyre?

[@rejean1337]

I used tub tape with no issue for an entire race season, racing mostly criteriums. It's so much easier to center and stretch the tub properly, it's way quicker, and way less messy. Just make sure the rim is properly cleaned before. Thankfully my bicycle was stolen (FML) and I replaced my expensive carbon tubs with expensive clinchers (Yay), no more tape vs glue debate now.

[@jeffbrunton3291]

If you want a cheap Lube alternative, don’t use car Lube. But you can try chainsaw Lube which is closer to bike chain Lube and a fraction of the cost

[@newttella1043]

But bicycle lube is very affordable and goes a long way. Tri Flow is a good all condition lube.

[@JH-fk8ow]

sewing machine oil is cheap and very similar to the thin bike lubes and it works pretty well but if you want really cheap and the lowest friction you should wax the chain as it will also prolong the life of drive train quite a lot compared to using oils, with the chainsaws industry is moving towards the natural vegetable oils because the oil gets thrown on the user from the saw and can cause skin issues

Tom, with a helicoil you drill it out and cut new threads in the size they tell you for use with the final threads you want to have, then using a tool, you take the helicoil and turn it into the newly cut threads and break off the tab and it's done. There's no gluing involved last I checked.

[@neilmdon]

Question: Is 1/2" pitch optimal for bike chains or just the way it is? I can find reference to a Shimano 10mm pitch track chain from the 1970s, but it seems to me that some of the challenges associated with the 1x might be mitigated by a smaller pitch chain. As Simon has pointed out, the spacing automatically gets troubling going from for example a 10 tooth to a 9 tooth cog (> 10% change in gear inches...) but if one were to imagine a 1/4" pitch chain (not that this would make sense), then the 10 tooth cog becomes a 20 tooth cog and a 19 tooth cog would fill the gap where 9.5 sits now... Obviously turning radius, etc is a big deal, but with the much stronger and higher quality materials around today, might it be possible to rethink the chain?

[@peterwillson1355]

NO. You are overthinking. It ain't broke, don't fix it.

I'm running a Ultegra 52/39 and 11/28 with a medium cage on my Canyon Aeroad 8.0 CF SLX disc. This gearing is fine most of the time as I live in Norfolk (the flatest county in England). I'm doing some hilly sportives (Yorkshire White Rose, Bike Bath, Dragon ride etc), So I'm wondering if I can change the rear cassette for a 11/32 or 34 without changing the rear mech or chain? Thanks in advance. #torqueback

[@elisgomer7164]

Probably not - Shimano and SRAM groupsets which can have wide-range cassettes need long-cage rear derailleurs to fit such cassettes. I use an 11-32 cassette on my SRAM Red setup and it's got a WiFli long-cage derailleur on it.

[@harrymunk8861]

Depends on what iteration of Ultegra you have, and whether your rear mech is SS or GS. A 6800/R8000 GS mech will handle a 32. The SS tops out at a 28. And whether you need a new chain or not will depend on how your current one fits. If its not long enough, you can extend it if you have some spare links. Might just be cheaper to get a new chain though.

Richard Isaksen Check with your local bike shop. They might have some in a random parts bin. My shop has helped me out a few times like when I lost a barrel adjuster while replacing my gear cable, or the time I lost a water bottle cage bolt. They didn't even charge me.

[@J.P.1.]

6800 shifters + 6700 RD: wouldn't the main concern be the travel distance of the RD, not the indexing? the RD is simply a slave, it isn't indexed, itself. as long as a 6800 cogset was used the setup should, hypothetically, work, right?

[@serdiezv]

I don't get why people still keep going with the discussion that using disc brakes is for more power. Anyone who has used rim brakes knows it's not that difficult to block the wheel and skid. The point is about how much control you have between pad contact and blocking of the wheel, which is far superior in disc brakes, also working way better in wet conditions. And I say that being a rim brake user, because I prefer the cheaper maintenance, lower weight and more aerodynamic profile.

[@galenkehler]

What disc brakes are not about: Power What disc brakes are about: Modulation Aero wheels Aero frames Low temp resins (stronger wheels) More tire clearance Supple seatstays Stiff chainstays Wheel longevity Consistent braking performance Heat buildup isolated from tires

Fish hooks: Only use if you are hooked on cycling; You will have to watch your line; Barbed comments may come your way; Your fellow cyclists may think something fishy is going on; You may have to scale back your efforts; You may hit a snag; Don't take the bait; and so on

[@troywillis9873]

Jon your floundering lures are amazing your fishing puns aren't going to fly. Hook, line and sinker here.

#askGCNtech New to road biking from the world of mtb and really enjoy the distance you can ride and the speed, my current road bike is to small and have been looking at the brand x frame aluminium and comes with a carbon fork and they currently have a batch cheap due to a decal misplacement is this a good frame and fork or should I save for longer?

What tubular tyre is in the main picture ?

[@3rdworldcycling444]

Disc Upfront and Direct Mount on the Rear could work with mechanical disc break, lever hood differences would be eliminated.

The guy with shifting problems between top 2 easiest gear has a b tension screw problem. He has almost certainly has a 1x drivetrain and these need the top jockey wheel to be as close to the largest cog as possible,(think SRAM eagle needs a special alignment tool, but is also the case fo1x11 to a lesser extent) wind that b tension screw out till you hear the jockey wheel hit the cassette between shifts of easiest gears then wind in slowly till the noise goes. Now the detailer is as close as possible without touching and perfect shifting.

I avoid the carbon tubular glue as it sets fast so you do not have time to adjust the tubular and get it perfectly positioned. Never had any problem with the regular glue going soft when hot

Just replaced my taped tubs last weekend, I'd invite anyone who says "never use tape" to pop round next time and give me a hand removing the old tubs.

[@jeffbrunton3291]

Justin Hodges - tape supposedly result in worse rolling resistance

[@jmh70]

J B Wow, I'd love to see the data on that.

[@ianowen3992]

Jantex?? Try Tuffo it’s loads better

[@waynosfotos]

Yep tape is brilliant!

[@waynosfotos]

Acyually I heard Tufo, had to reduce the strength of their glue on their tape as it was damaging carbon rims. Now people are a little paranoid about tape and carbon rims. I have taped heaps of tyres, use velox 176. Not a problem with carbon

[@dominickslush3593]

what is the benefit of going tubeless vs regular clinchers?

[@justinsparhawk6755]

You can run lower pressure with out going slower because of lower rolling resistance. Better comfort leads to longer endurance as well. And you will not get flats other that catastrophic failures that would destroy any tire. No flats from thorns and the like though.

[@felixlessard7000]

Question, could you use sealant in a tubular tyre to avoid punctures ? If sealant can fix punctures in tubeless tyres, why wouldn’t it work in tubular ? Thanks

[@waynosfotos]

felix lessard Absolutely, I run 30mls of stans permanently in my tubs, which I ride everywhere. Latex tubes (which are in good tubulars) seals better than putting sealant in butyl tubes.

[@cliffstokes2260]

Get reeled in faster on a sole breakaway by using Shimano fishing hooks to pin your race number to your Jersey; I lold.

[@christiandegroot2079]

And yes, patch the tubeless tire from the inside. In my experience that latex "seal" never lasted too long.
