Tyres need to match the wheel to work properly and be faster. On the older 2nd hand wheels they will likely be a narrower rim and mate more aerodynamically to a 23.

You can descend on Continental Supersonics with disc brakes just fine 😁 I've used Supersonics for the last 5000km with only two punctures (one a huge nail which would've gone through just about anything) after I figured you have to be careful installing them. Latex is better than the light butyl tubes, but Supersonics are really an "extralight" tube, would love to see if they close the gap to latex.

[@ErlangS]

Great series, Oli. I really enjoy this approach and find your presentation here insightful and inspiring. Well done, looking forward to see how far you can take this bike.

[@alexnaturalis1179]

Didn't know latex tubes were a thing, nice one. Glad I subscribed to gcn tech.

[@chrispyy606060606]

This is a great series. I used to run latex tubes but had them spontaneously pop in the paddock or in the house getting the bike ready to go to a race. It happened three times before I said enough is enough and went back to butyl. (This wasn’t right after install either, it was after a few rides training and a couple races) Not sure what was up but it made me wary of them.

[@neil7769]

Have you considered having your collarbones broken and reset to make your shoulders narrower and more aero, as mentioned by Michael Hutchinson in "Faster"? Expensive to have done professionally no doubt (and you'd probably need to go to Thailand or something), but you could try to bodge it at home, just get some big wrestler or bouncer to do it for you.. Would make a great GCN series, following the recovery process, aero testing before and after, etc.. 😉😂

[@Wildschwein_Jaeger]

I use the latex tubes and the ride is comfortable. I carry a beutile spare.

[@georgehugh3455]

Skipped right over the addition of valve extenders - would have been worth covering how Ollie prevents leaks. Reiterating the PITA daily pumping up of tires with latex tubes seems in order (but I guess didn't mesh with "easier life" motto).

[@kylewheeler6860]

Instead of buying hi rise extensions I made my own for £8. Bought 22mm dia aluminium tube from tubing manufacturer, measured and cut to custom length and bent to custom angle. Just an idea.

[@panzerveps]

The rotational direction of road tires is pure aesthetics. If the tires have knobs or water draining fins, it serves a purpose, but if not, it's just for looks.

[@SimoD587]

I remember an interview talking about the rotational direction mostly being put on on slick road tires to keep people who NEED to know which way it's supposed to go happy, with negligible difference to performance

[@PeterLeder]

Lube and Latex. Best bang for a lad.

[@hebrews11vs5]

Stole my tubes, my tires and my bike lube. The breaks are new to me, I did not know about those. But if you are going for a serious race, get ceramic speed's liquid wax, applied just like the squirt. It's expensive, and I noticed it doesn't store well for long, but it's probably very close to a full on wax chain. It beats squirt for performance.

[@Raptors0524]

I am so mad that you got a tire on that easy. I tried to install a trainer tire and was struggling 😂 Nice video

[@vgjgghbgyjn1985]

With a shimano rear hub there are 3 seals that can be removed. What is left is a hub you can fully flush every 50 or 100miles. One of the seals covers the freehub. With it removed the pawls get washed too when flushing. And the pawls engage less at high speed and the sound changes to more quiet. Its really nice. Martha Stewart would say its a good thing

[@MrDerpySquid]

I can attest that the wax emulsion lubricant in this video "Squirt" is amazing other than watts it keeps your drivetrain clean and lasts around 400km per application it's really unlike any lube I've ever used.

[@davidpinnington213]

Agreed

[@davidpinnington213]

M. A. - I’ve used various dry lubes when i worked in middle east up to the insane priced muc off ceramic - you will have more noise (it’s dry) and it evaporates out to form a dry film - that said any rain or sustained wetting of drive will quickly wash a dry lube off - Now back in UK I’ve been running wet on my mtb over the past month and I’m about to switch back to dry - squirt specifically!!

Thanks Ollie. Top -tips for Watt-gains.

[@mrmatthewking]

Great series Ollie. How about some aero (non-QR) skewers? Small gain, but pretty cheap. Aero water bottle. Chain - you really needed to discuss cleaning out the old lube first for proper benefit of a wax based lube. And frankly I find wax super easy once you've done the initial cleaning (which isn't hard anyway) and have a quick link and pliers. Plus a gold chain would be faster, you know that. And to nitpick, you totally failed to mention that latex tyres need pumping up before every ride.

This series is fantastic. WIND TUNNEL THIS BIKE 😆

Ollie, I’m intrigued by your comments about latex v lightweight butyl tubes and wondered whether GCN could explore this further. I had a blowout on latex tubes which caused me to crash and the crash snapped a chain stay so all told, quite expensive and a bit of a bummer. Not to mention painful road rash! The tyre survived and showed no sign of a puncture. Fortunately it was on a flat stretch of road, but worrying still because I’d just plummeted off a mountain 10 minutes before. I’ve now got lightweight Conti butyl tubes but your comment about descending scared me a bit. I was always under the impression that latex tubes are also prone to overheating. Like I said, maybe GCN could explore this one day.

[@guidospanoghe8896]

I also suffered from a blowout with latex Michelin innertubes. Luckily it was on the way up the Col de la Bonnette! Dubbelcheck your tires after installation when hitting the mountains please.

[@guidospanoghe8896]

Just had my first long ride on my classicskin Schwalbe One tubeless tires inflated to 5.5 bar. It felt like riding on Michelin tubulars with latex inner tubes! Since they kept their pressure after mounting ( on Fulcrum alu rims ) and inflation I didn't put the sealant in yet. I'll wait for my first puncture to put some in (on the fly, through the valvestem). I wax my degreased chains with paraffinwax and use Squirt when the chain starts making noise. Rather informative video this time, keep up the good work Ollie!

[@ChrisB200SX]

Halo Hex Key skewers. £8, save some watts when a quick release is a pointless without a team car following you.. Hadn't seen that brake before. I've got a couple of Tri-Rig Omnis off my old Tri bike. You might find the rear brake is the bigger gain as it should reduce the negative air pressure area, in front of the head tube should make less difference. I'd do both.

[@eriksmith5898]

About that tire gap in the back. If, no when you hit a sticky tarmac and pick up some small flint or pebbles it is going to sound like the frame split in half. I've been there. min 5 mm I say. Also Look says that a narrow clearance slows you down, moving surface close together thingy. Consider drilling a small hole in each drop-out from behind and screw in a small screw to move the wheel backwards. It is standard on some frames. you might even get away with a bigger tire as mentioned below. Do not try to pull the wheel back and let the quick release hold the tire in place, it is futile.

[@brianschiff7371]

One nice thing about being locked down in a pandemic is I have all the time in the world to wax my chain!

[@myPPPLab]

proper rim tape also if gone use latex tubes

[@luclarrousselacou5603]

Aha! Lube the latex !!!!!to proper install the latex tube always powder them with talcum ( silicon spray is also ok if you have some), otherwise the outer surface of the tube will "stick" to the inner surface of the tyre and the tube will stretch more on the rim tape area+ if you ride in wet conditions it also helps!

[@luigivm]

Maybe go to a single chainring and a wider range cassette would be a great idea: 25% less air ressistance from wires, you avoid also drag from front derailleur and one of the rings (this point I think maybe it's unvaluable), Don't remember wich drivetrain it has, but maybe Shimano 10 Speed road shifters + XTR 9 Speed (m970 or M960, second one would look better on a roadie) and you can reach a 11-34 range with 10 cogs, even to save some weight (it's not drag reducing but you also make your watts more effecitve). Other crazy but maybe effective idea is ti create a cable hiding system, something li the Tri-Rig delta Aero Cover, it hides the cables and the front brake to reduce the air drag.

[@assortedexorcist2645]

I like pink tubes

[@theparalexview785]

I've had good luck with Continental Race 28 Light tubes on a couple of bikes over the past year, with Conti Grand Prix Classic skinwalls (pretty, but not particularly low rolling resistance) and Ultra Sport II (great cheap tires, feels very much like riding the Grand Prix Classics). No puncture flats. I got them mostly to fit inside a dinky Lezyne Road Caddy bag (they roll up tight and tiny), but ended up riding on 'em. They're quite good as butyl tubes go. We don't have any serious descents here where I'd need to brake often so rim heating hasn't been an issue.

[@rouxenophobe]

I'd wager that a latex tube will only make your bike faster if your tyres are also super compliant. It's all down to ease of deformation at the contact point. I don't think latex will make my Schwalbe puncture proof commuter tyres any faster!

[@makewhatyoulike119]

Ollie, I'm not a knowledgeable bike guy, but I own a 2014 Cervelo S5 and i am contemplating wider tires. I ran across a video of Gerard Vroomen introducing the new 3T Exploro Max in which he says that when he wanted to fit wider tires on his old Cervelo he just scraped the paint off. Just sayin.

[@Pav_1983]

Hi Ollie, I'm loving this project. Can you dig deeper and find out what are the aero savings of narrower bars? Example going from 42cm to 38cm. I think this would be more important for a road bike. I look forward to your update

[@OliverYoungFinance]

Rear drop out is a rail so all you had to do was push the skewer back a bit in dropout and you probably could have fit up to a 28mm in there.

[@julmeissonnier]

You should finish putting the tire where the valve is. Because you can push on the valve to avoid pinching it... believe it on not it is actually MORE important than aligning the logo ;) !!!

[@jerryjin3427]

I got a “puncture” in the area right across the valve in my super light butyl tube, without seeing any holes in the tire...

[@RichardMigneron]

"Part of me want it to win !", would give you a good excuse to sell the Orbea ... and then with the money launch the "Lightest climbing bike on a budget build" !

[@runningwithshemp]

Latex tubes sure are great, more supple, lighter, less pinch flats, more grips, but man fully pumping up tires before every ride... vs just topping off the butyl's does get old (appox 5-10 psi). Also I ran some Challenge SL latex tubes in my 35 mm all round bike didn't find it made much difference in fact it felt like need to run them 10 psi higher to get same feel as butyl's as tube was so thin. Above 30 mm feels like tubeless with sealant is just more workable

[@pktesq]

Hi Ollie - I'm a big fan of GCN. However, you have mentioned a couple of times that (at 5:00) that the Cervelo does not have clearance for 25 mm tires in the rear. THIS IS NOT TRUE. I have this same Cervelo P1 bike and I use 25 mmm tires. The rear drop outs are horizontal for a reason. If you remove the rear wheel and look at the rear dropouts there are set screws hidden in the front of the dropout slots. The set screws can be adjusted to move the rear wheel axle back so you will have room for a 25 mm tires.

[@MrHumbletrev]

you should've posted a before and after wattage of the bike to show all the final improvements, as well as the comparison to the expensive tt bike

[@mattd5136]

Ollie, if you want your unnamed wax emulsion to work it's very best, you still need to get your chain very extremely sterile clean before applying it. Having gone to that much trouble, you might as well go the last step of enjoying a cup of tea while the chain sits in the pot and cooks the wax in. If Jon and Si had a noisy chains 60km after fresh waxing, they did something terribly wrong in their process.

[@gcntech]

Yes you should definitely clean your chain very thoroughly for the best performance!
