Rick, yes, latex takes some extra care in the setup, rim tape and installation, but is certainly worth it in the long run, for the feel alone , I'd say worth it, and when you factor in the efficiency, even more so!! Yes, the socks were a real eye opener for me.. we literally re-ran the tunnel test as I was SURE something was broken the first time I saw it!

Great video, I could watch this sort of thing all day. Couple of questions for you: 1. Aero socks seem like a no brainer to me, but why don't pro triathletes wear them? There's no rules from UCI and the gains extrapolated to an ironman must be minutes rather than seconds - easily offsetting the 20 sec it takes them to put them on. 2. How important are shoe aerodynamics and which models are good to look at? 3. OK so it's three questions, do any overshoe companies incorporate the ribs on the calf for similar gains?

Great video Josh. Long time fan of your work and reader of your top input on Slowtwitch. A few questions: 1. How does the Wipperman Connex chain compare to the Dura Ace 9100? I'm a DA fan, but heard good things on the Connex. 2. Where would a cronically under-waxed, or completely bare chain sit in terms of wattage losses at, say, 250w rider output? 3. It not an 'upgrade' or strictly UCI legal perhaps, but what about adding silicone sealant to the tire/rim interface 'crack' to smooth out the airflow? Could easily be removed? Surely a big saving, especially if interface isn't neat beforehand...? 4. My addition would be aero skewers... but not great for wheel changes.

1.The Wipperman is a really beautiful and amazing piece of kit. I use Wipperman quick links on all my chains, but the DA chain shifts a bit better and runs about 0.6 watt faster. 2.A waxed DA chain can run sub 4 watt loss on 250 and a chain with White Lightning dry lube can run at 12w+ loss after just an hour of riding it. A squeaky dry chain will run at 15+ watts of loss depending on what it had been lubed within initially and how much is left, and a totally dry, stripped chain will run at 25+ watts of loss! 3. Silicone can work and we used to do it for key events like the TdF way back in the day. To really work properly, the tire/rim widths have to be equal or better, obey the rule of 105.. unfortunately, this also adds Crr to the system which can offset some of the gains if not all of them. 4. This is a great one for TT or if you have a team follow car!

hmm..about that chain. One could learn a lot by testing the Rockwell hardnes of the plates & pins and figurinig out what the metal finish is for the pins and plates. I think about all the things I've seen precision machinists do and I think mabye Shimano's manufacturing process allows for better surface finish and or special coating that afffects the side-plate to aluminum interface of the chainring. The Ceramicspeed dudes were claiming significant improvement in efficiency using a factory-applied (PTFE?) coating which would last 500 miles. They claimed they were supplying to several pro teams a while back (don't know if that's still true). I'm using parafin mixed with PTFE powder on my chains but I'm not a racer and don't have any way to test it. A long while back Campagnolo had a video of their chain assembly machines in action.

I would love to see some data though...hub mfg, design, freewheel efficiency, bearings, etc. I think new wheel bearings would fall into your
@SILCAVelo4 жыл бұрын
We are working on a show about bearing losses now, but your specific situation is a little bit real and a little bit placebo! So the total losses from a subset are at most a couple of watts.. which is why at best, ceramic bearings can save about 0.8 watts when compared to REALLY poor hub bearings. So you King hubs probably absorb 2-3 watts at baseline and as they get dirty drift up to maybe 3-4 watts, but the clutch mechanism is much more sensitive.. it might absorb 3-5 watts when coasting and then when dry or dirty as much as 7-8 watts.. so cleaning and regressing the clutch can make a really notable difference in feel. To put all of it in perspective though, removing ALL hub frictional losses combined is only about equivalent from moving from a Continental Gatorskin to a GP5000 rear tire.. and moving from butyl to latex inner tube in a rear tire is similar to elminating ALL hub bearing drag.. so the placebo piece of this is the sound. Whenever I rebuild my hubs or BB, I feel exactly the same way.. the sound just makes you feel so unbelievably fast! - Josh

This is almost true in pure rolling resistance terms, but remember that latex tubes are more resistant to both punctures and pinch flats than standard butyl tubes, while lightweight butyl tubes are disproportionately MORE likely to puncture or pinch flat than standard.

@SILCAVelo2 жыл бұрын
It's all about boundary layer thickness and location of the trip zone. For flow on the lower leg, the boundary layer thickness for tripping is about 1mm, and you only need it right in the separation zone, so with hairy legs you have ~1cm long hair everywhere making a big mess of the airflow. Theoretically you could leave 2 thin stripes of leg hair at ~+/-40 degrees of the center of the shin, and then keep those stripes trimes to ~1-2mm max and have a similar effect to aero socks.

Considering that latex tubes are more resistant to puncture flats and pinch flats than butyl tubes, it will always faster to run the latex tube. They can also be run with sealant in them for key events and will seal better when used with sealant than a butyl tube used with sealant. Really the only downside of latex tubes is that they take considerably more care when installing as they are so easy to pinch between the rim and tire, and also require nicely fitted rim tape as they can really get into all the little nooks and crannies otherwise. But overall, 5 extra minutes installing at the outset will pay dividends for years afterwards.

I have used latex inner tubes for over 20 years now. They offer such a great smoothness while riding and low rolling resistance in addition. In only two occasion tubes exploded due to my bad mounting. Ever since I shake latex tubes in a plastic bag with baby powder before mounting, do not use levers for mounting and take really really dillgent care that the tube is within the tire there was not problem any more. Pressure loss is significantly reduced with 30-60ml of Stans sealnant (23-35mm tires). I have very few punctures (10-15.000km/y). Repairing is easy and durable with TipTop patches if done properly. Be very cautious with even a small cut in the tire. Latex is so flexible, it will creep out even of the smallest cut and cause a flat. You have to cover cuts from the inside of the tire! And carefully check your inner rims and rim tapes before mounting!
