Zipp 303 S Carbon Tubeless Wheels 1000 mile Real-World Review

[@orlandostuart5805]

Just got a 2021 TCR with 2021 Zipp 303 Firecrest with the Pro One Tires. I’m all in! Thanks to your videos....

[@uprightape100]

That's a lovely set up.......Domane with those wheels and disk brakes, I'm a little jealous.

[@davidarthur]

Thanks Diego 👍

[@JonFairhurst]

Your advocacy of wide, tubeless tires on road bikes in the real world is spot on. On imperfect roads, you can smash through corners and bomb down hills without worry. I have ENVE AR 4.5 Disc rims (also hookless, a bit wider, a bit deeper, and $$$) with Schwalbe Pro One 28mm tires, and the setup is so, so good. The Zipps look great for less cash. (ENVE has released some more affordable wheels as well - after I bought my ARs.) I had a rim brake bike with 23mm and tubes. At 110+ psi, I kept getting pinch flats. Upgraded to tubeless wheels and went with 25mm. I no longer flat, but the bike still skitters on rough roads. By comparison, 28mm tubeless is perfect for me at 185 lbs. (84 kg) with 60 psi in the front and 65 psi in the rear. It’s not just for comfort. It’s faster, due to my increased confidence. It’s more fun and comfortable too! On glass smooth roads, my rim brake bike with narrow tires would rock. I hope to ride on such a road someday.

[@HaswellCore]

do you think its worth upgrading from Continental 4000 28 tube to Continental 5000 32mm tubeless?

[@JonFairhurst]

@@HaswellCore - It depends. I find that 28 is great for my summer bike with deep wheels. They’re fast, light, and aero. I like 32s on my winter bike for comfort. If your roads are smooth, 28s are probably fine. If your roads are rough or if you are a heavy rider, or just want more comfort, 32s might be ideal.

[@HaswellCore]

@@JonFairhurst I got a flat 28 on the front and a snakebited 28 with a working tube on the back.. Is getting one 32mm for the back a good idea, dont want to throw away the working 28mm tire.

[@JonFairhurst]

@@HaswellCore Bummer! Yeah, you can mix and match. If you bomb down switchbacks, you might not want mixed sizes, but for normal riding, it would be fine. Probably 5-10 fewer PSI in the 32s than the 28s.

[@BTcycle]

Thank you for helping me decide on my next carbon wheels.

[@originalkontrol]

Exactly what wanted to know, great job! I’ve just ordered these along with some new rotors and a set of the Pro One’s for my Revolt. Can’t wait to get them on!!!

[@gcnot385]

Had to return these wheels - early builds didn’t have holes to let the water out plus the bearings are susceptible to corrosion if the wheels get wet (1-2 rain rides and a few washes). You can send them back for drilling to the factory but a bit of a hassle. Besides the quality questions on the hubs, they ride really well for average roads performance wise, but don’t ride near water

[@philallan6685]

Nice review Dave, very helpful. Like the way you've split the timeline into sections - first time I've noticed that. Excellent!

Thanks Phil! It’s a new feature introduced by YT and think it’s good for the viewer as you can skip ahead if you just want to watch the ride section for example

[@anthonyychapa]

Nice review as always, David. I was on the fence with these and the Enve 45 wheels. I ended up going with the Enve set due to the fact I couldn’t find any Zipp wheels in stock for Shimano. They’re pretty equal I’d imagine and both solid offerings.

Hi David, I really enjoy your channel! Since you recently tested the 2021 Giant TCR with Giant branded SLR1 42mm Hookless tubeless wheels, how do the Giant wheels compare to the Zipps? I'm getting a 2021 Defy advanced Pro and they come with the same wheels (the SLR2 actually) and I'm curious how they would stack up to the Zipp? Having a good pair of carbon aero wheels right out of the box is what made decide on the Defy instead of getting a Domane or a Roubaix. I would loved to know your opinion, perhaps a new video idea for you!!! Thanks and again your content is great!

@@HowayTheMags My local lbs showed me the pictures and specs. They're already ordering 2021 bikes. I suppose that Giant has started production on their 2021 range sooner this year. I think it's a smart move from Giant to spec the pro models with their 42mm aero wheels instead of last year's 30mm. Really saves me from buying another wheelset.

[@Kansloos]

I am curious aswell, and i hope he will answer you question. Iirc he also going to release a video about improving the bike with different tires then the default.

[@davidarthur]

The key difference between the SLR1 wheels and the Zipp 303 S wheels is the internal rim width, 19mm versus 23mm. The latter suits 28mm and wider tyres much better (smoother profile) so that is something to consider

How much pressure are you using with this Zipp wheels? I’m looking for those wheels in my new Emonda SLR, but I’m afraid to can’t ride with a lower pressure of 80 psi. I’ve been riding with 23 mm tyres yet and it I’ll be a big change in my riding style… 🙈

These were looking very tempting. I ended up going with Enve's Foundation 45 instead for their crash replacement and (IMO) far better looks. I'd be curious to see someone compare the two!

David, I wish we were neighbors. Beautiful countryside.

[@tyesjazz]

I got my Zipp 303s wheelset last week and we put the Specialized S-Works RapidAir Tubeless tires on them and so far so good. You cannot beat the price point!

[@paulappleyard5832]

I think these are a bit of a game changer and are at the top of my list I can't see why you'd pay £800+ for a rebranded Chinese rim when you can get these with a cracking warranty . I think the market needs a bit of an adjustment I looked at the importing well known Chinese brands and ended up at £600 before taxes. I've just Won a Cervelo S3 and it's great but it's pretty busy even compared to my Evo. I want to do a few more rides and change a few things first but I'm hopeing these will tame it a little with the low pressures I already run 80psi on clinchers.

[@zTheBigFishz]

NIce consitent content. I run Conti GP 4 Season 28mm clinchers on HED Ardennes alloy wheels. Let me tell you that mounting those tires is substantially more dramatic than your demonstration. I've been nearly brought to tears replacing one on the road. Therefore, hookless sounds great to me. I weigh roughly 83kgs but I run 80psi fronts/90psi rears on said Conti's.

[@davidarthur]

[@philipturley389]

Great review, thank you. But as with cycling gear it always provides a question. So I’m a rider of between 75/80kg, would you choose these or the Roval C38’s ?

[@thenerdymamil8557]

Thanks for sharing your experiences! I also got them. I hope I will be as happy with them as you are. I am also a light rider and like wide tires at low pressure :D

[@om1kron]

I currently run these wheels on my roadbike and while I don't have 1000 miles I have a few hundred on mine, I haven't had any problems with them at all. I run zipps tires on my wheels and I am 5'8" / 172cm and am 225lb / 102kg. I've got a few 1000M of climbing and hill descents on them, a few 45mph / 72.5 kmph runs and my confidence grows the further I push the bike. I would highly recommend these wheels, just the fact I don't have to fill them with 30-40psi worth of air every time I go ride, like I had to with my previous tubeless setup is a huge plus.

[@davidarthur]

Sounds good thanks for sharing your impressions of these new wheels :)

Hi David, Thank You for the awesome review. I saw you have the Schwalbe Pro One (TLE?) tubeless tyres & you were able to just install it over the hookless rim & pump it up with what looked to be an ordinary bike pump. Do you know if let's say this tyre has a huge cut, will I be able to put in an inner tube (after removing the sealant & removable valve), & pump it up & ride on it safely, especially on a hookless rim?

[@jjames2162]

Great video. Love to k ow where you are. If I had to have one wheel set it would be Reynolds. I own Reynolds, Fulcrum, Zipp, and Roval. My favorite are the Reynolds and Fulcrum. Zips don’t have the same durability and the Rovals are not nearly as still (60kilos here)

[@Jeppelelle]

I'm currently looking for a new bike & the Tarmac SL7 is one of the contenders which comes with Roval wheels, so i guess you are saying that the Rovals isn't as stable in gusty winds? Do you think it's a non issue for me that weights 80kg?

[@jjames2162]

Jesper Andersson Hi Jasper, the SL7 is a sweet bike! You should totally get one. A friend of mine just bought one. As far as wheels go, anything over 50mm will be subject to wind BUT! some are more than others. At your weight it is just about practicing handling skills. Like anything else. That being said my Fulcrum 55 get pushed around less than some other brands. I like Reynolds too. The Rovals are not as stiff in comparison and do not have the same tolerances as Reynolds and Fulcrum I can put any tire I want on Reynolds or Fulcrum and never have to worry. Rovals are only good for about 110 psi. Not only that but if you pump your tire above their recommended psi for rider weight (see their website) the tire feels squishy and almost like it’s moving around on the rim. I’ve never experienced that with any rim. So for example a rider my weight Roval says I should use roughly 60psi on size tires 28 - if I pump them to 80psi they feel squishy, flexy, and like the tire is moving Get the bike and experiment on your own. Developing skills with deep dish wheels just takes experience

[@ramirohernandez2457]

Thanks for your video and awesome content always. Would you recommend this wheels or the Fulcrum Wind 40db? Or other option at this price range? I’m looking for a versatile, carbon wheel set that has aero benefits but light enough for lots of climbing. And also a good price. Thanks David, have a great week.

[@DantetheHell]

Hi David, great video as always! I have a Domane SL5 and I have been eyeing up these wheels. Im just worried I might be too heavy 14 and half stone 6.1” I used to play rugby so I’m a bit heavier than normal cyclists. Also new to the tubeless, you reckon I can get used to swapping wheels and tyres?

[@jasboehlke]

Have you noted any sealant leaking around the side walls? I have this wheelset with Schwalbe Pro TLE 30mm and can't stop them from weeping sealant.

[@JasonHughesUK]

Add sealant at 5:54? Do you not need to add before blowing up? Is the sealant only for small punctures and to protect from sidewall leaks?

[@paulappleyard5832]

Let them down and inject/remove through the valve core and then reinflate I guess. Alot less messy than many other methods I've seen.

How was the hill climbing with these wheels and the Domane? How does the Domane climb hills compared to an Emonda?

[@davidarthur]

Climbing performance is very good, lots of stiffness so no flex when putting down the power, and lots of traction on very steep gradients. The Domane climbs well especially with the low gears but it's going to be heavier than the Emonda which you can feel on steep climbs

[@mikebrown600]

david arthur Hi David, thanks for the reply. I already have an Emonda. I also live in Kyoto so I’m surrounded by mountains. I’m getting a Domane because anything over 40km and my back starts aching. I’ll use the Domane for long distance rides because Kyoto is flat if you follow the river bike paths. I’ll use my Emonda for the local hills where I didn’t have to travel to far to use them. My main concern is that occasionally long distance rides will face the inevitable hills so I hence my question. Sounds like the Domane will do the job admirably. Cheers, mate!

I mainly do 85 - 120km rides and think the Titanium will make a lovely mile cruncher. With Ribble's bike builder it is these over their own brand Level or a big jump to Enve Foundation 45s (another 400 quid). I was totally sold on the 303 until you said about heavier riders and low pressures...I am 82kg and used to higher pressures (not that I have any strong opinion just what I am used to.) I have a lovely KTM race bike with gorgeous Ursus Miura 45s....wonder how these will compare and also your thoughts on my weight with 6s psi and tubeless. (I run the Ursus wheels with tubes currently) Thanks and great video!

[@davidarthur]

The titanium will be ideal for that sort of riding. Wheel choice is tricky, I've been really impressed with the Enve Foundation 45s and they might just be worth the upgrade. Regarding pressure at your weight, provided you're running wide tyres, say 30 or 32, you won't want very high pressures at all even for your weight.

try that: mount the tire with a tube deflate, brake only one side tire bead (important!) and remove the tube install tubeless valve put tire back on rim get a sponge with soapy water and rub some between tire and rim bead inflate tire again if still doesnt work and the tire seems too lose, you can try to add one or two layers of rim tape and repeat the process above.

Nice review. Thanks. I currently run Tubeless on PR-2's and looking to upgrade. One of the challenges sometimes is getting the tyre bead to seat in the rim so that when you let out the pressure and remove the core you can add sealant , replace the core and just reinflate .... With hookless rim, where does the tyre actually seat, I heard the pops as per normal tubeless and if you let the pressure out and remove the core, do the tyres still remain seated ? Also if you do suffer puncture that sealent cannot fix at the side of the road and you have to put in a temporary tube, is hookless likely to cause any additional challenges ?

[@gcnot385]

early production runs don't have drain holes. If you ride in a dry area, the first time your ride is in rain or you wash the bike, you'll get an unpleasant surprise ---Uber home....the wheels sponge up water and don't drain [if you spin the wheels and bump for an hour you can get 80% out]. Zipp will warranty drilling holes at their factory in Indiana - bit of a hassle and concerns about shipping back and forth damage and being bike-less for a long time. Not a good customer experience. Beyond that, the wheels do ride nice, and now that the Continental 5000 will support hookless tubeless the tire choices increase. Wish I kept my old wheels as spare :0(

Most new tubeless tyres are these days, take your pick from Michelin, Pirelli, Goodyear, Continental, Vittoria to name a few examples

[@heliocorreia1814]

Hi David, for you what is a heavy rider? 82 kg is heavy for that wheels?

[@davidarthur]

Zipp sets a maximum weight limit of 115kg for these wheels, if that helps?

[@heliocorreia1814]

@@davidarthur Yes it helps :). I used the zipp calculator, if I can get to 78kg I can use the 25mm tires, if not the 28 is the best tyre. Have you tested this with 25? you said it's optimized for 28, but can it be faster in 28?

[@nelson2812]

Hi David. From the first 303s reviews that you’ve put on that I’ve been at your channel and instagram looking for the real width tire measured when fitted. You’ve told earlier that you would post on Instagram the measure tire width but if you did that escaped me. Can you already tell what’s the exact width of 28 tires fitted to these wheels? Thanks

[@davidarthur]

I posted a picture on my channel under the community tab... these Pro One tyres measure 28mm

[@nelson2812]

Thanks David.

Great review :) subscribed to the channel :)

Thanks for the sub!

[@donoldduckben]

Built mine with a Dt swiss 350 hubs and 50mm t800 carbon rims for much less, and legitimately can't tell the difference between the way they ride

1:08 - 1:12 did anyone else think of the Captain from Police Academy? “Many, many...” 😂😂 Sorry 🤣

[@jayaybe1]

No.

[@brunocosta3877]

Are they compatible with clincher tires with inner tubes?

[@g.popstefanov5948]

Can you tell us about the SCOPE WHEELS? Saw them in a couple videos but would love to hear your feedback. Thanks!

[@davidarthur]

Yup been impressed with them, had them for quite a few years and they have been reliable

Yup I've used them bike packing with no issues

[@petercallaghan6987]

Hi. Firstly great videos. I really enjoy watching your channel. I was wondering what bike you would prefer as I’m about to buy one. The trek domane sl7 etap or Specialized roubaix expert? Iv been offered both at around $7500 Australian. I currently ride a diverge comp e5, setup as a road bike. It’s a tough choice between the sl7 and expert.. any advice would be awesome! Cheers from perth Australia 👍🏻👍🏻

[@mikebrown600]

Peter Callaghan Ex-Perth boy here (now Japan). I can’t address your question perfectly, but I do have an SL 6 Domane. Beautiful bike and even better ride. Finishing 100km feels like you’ve just finished 40km. Smooth as fuck.

[@allenk9342]

A new Zipp disc carbon wheelset below USD1,000? Sounds perfect for my new built with Cervelo S3 Frame + DA9120 groupset with Conti SP5000TL 28mm tires... wait a minute, did you just say this 303S not recommended to be fitted with GP5000TL ? Oh crap...

[@davidarthur]

Continental advises against using its new TL tyres on hookless, but there are plenty of other good tyres to choose from that are just as good, if not better imo, than Conti, so maybe don't rule them out just based on that? Though I guess if you really must have Conti it's an issue

[@allenk9342]

@@davidarthur Hahaha... Just teasing, no worries! I have been using a set of GP5000TL 25mm for 4000km+...Smooth, handles well and without any punctures. Not the fastest but an awesome set of all-rounder tires. Sad that 303S couldn't fit them but it's obviously not end of the world. I shall try out the Schwalbe Pro One if I buy this wheelset. Thanks again for making this informative review!

[@kirkshammett94]

That just seems like such a low pressure to run in the tire. I run tubeless on my hunt wheel and run 80psi. Wouldnt the rolling resistance kinda suck with that low of pressure

[@kirkshammett94]

I take this comment back. I now have these wheels and can confirm they are fast!

[@flaviobatista2096]

@@kirkshammett94 Im a little bit "scary" to make the step and buy this ones to go full tubeless ... how about the feeling? Im using 100psi + clincher, 28mm tires. Did u feel lost of "speed" and "stiffness" in sprints?

[@kirkshammett94]

@@flaviobatista2096 I ride in a lot of fast group rides, and sprint a lot with these wheels. They always feel very stable and the low tire pressures do not affect my sprint at all. I’m 165lbs with a max sprint if 1400 watts for reference

@@kirkshammett94 wow, thats amazing news m8, im 71/72kg average and my peak watts are around 1200 (ish) ... How many psi do you use on it ?

Rear hub failure in under a year ... sram 'lifetime guarantee' does not apply to failed seals (or anything else I wouldn't be surprised). I'd look elsewhere, mine were well maintained and bike had pride of place in the lounge.

[@dustingreenhill9711]

Hi, I've read somewhere that Continental tyres aren't compatible with these as they're Hookless? True /False?

[@davidarthur]

Correct. Continental advises against using its GP5000 TL on hookless rims which these aren't. Plenty of other good options that are compatible though

[@desaljs]

Conti is just now offering a GP 5000 that is hookless compatible.

[@stevenr5149]

nice review

[@Jarek.]

Another downside might be in case of a puncture which cannot be sealed, common and perhaps fasted method for fixing it to get back home is to install a tube. With this hookless wheel I’m guessing it’s not possible?

[@rorysellar6613]

Great question!

[@fradd4045]

when they say tubeless only they mean the tires used MUST be tubeless designs, fitting a tube to get yourself out of trouble will cause no harm

[@Quevallyn]

JarekMa2 carry tubeless plugs like mountain bikers.

[@rorysellar6613]

@@Quevallyn I do, and have used them but occasionally you have to fit a tube. So the original question still stands!

[@paulappleyard5832]

You can fit a tube function no problems

[@PBabel-ne3hc]

At 2:27 there is a scary delamination of the rim surface or just something else?

That's just how carbon fibre looks sometimes when it's been moulded - the days of putting a decorative layer over the top are gone which is why they sometimes look like this
