I’m a bit late in replying then…sorry! I don’t have any specialist knowledge on kit, so I could only quote you what they say on Slowtwitch, which would be this.
"Since these 2 topics, skinsuits and helemts come up frequently and we’ve (ex-cyclist and I) helped with the design of a couple of them and tested more and have tested > 75 people there are a few rules of thumb to keep in mind if you’re not going to test.
Go with the helmets that seem to work the best for the most number of people and avoid the helmets that seem to work the least often. The helmets that work most often are the Giro Advantage 2 (top 3 helmet about 90% of the time) LG P09 (top 3 helmet about 85% of the time -although when this one is bad it tends to do worse than the Giro A2). The new Giro Aerohead seems to be doing really well for most of the tests that I’ve seen, although I’ve only tested it on 1 person and it wasn’t that great.
There are certain helmets to avoid bc they just aren’t typically fast unless you’re in the 5-10% of people super lucky. The Bambino, the Rudy projects, road aero helmets for TT’s (yes we’ve tested them vs TT helmets)
Or go with leegohead’s suggestion and buy the one you like the best if you’re not going to test, even a slow TT helmet is faster than your road helmet but can be minutes slower than the right TT helmet.
When it comes to clothing it’s all about the fit. You want very little to no wrinkles along the clavicles and shoulder/armpit area. You’ll have some wrinkling but more is worse. You want sleeves that go down towards the crook in the elbow and you want the longest legs you can find. Basically cover as much skin as possible."
For overshoes, I think it’s safe to assume that the above rule applies - look for overshoes that leave the least wrinkles. Possibly, I would look at the nopinz stuff with the trip overshoes, though I note they stock the velotoze, so those must be quite decent. I notice the ride across america guy used their trip compression calf. I might look into those, as I can’t run without compressoin calf sleeves, or the risk my calf might spasm becomes too great, plus, it is a good way to cover up my hairy legs when racing! However, I do know that BOA dials don’t test very well, so lace ups are faster, even more so, if you can cover over the laces, e.g. with tape or overshoes.
I hope the problem with the shimano cranks isn’t related to all these recent fake quality certification stories relating to Japan inc. I think the dura ace cranks are made in Japan…perhaps that is the problem???
For the shorts guy, I think the infamy wasn’t worth it! If it was for a race win, then yes, I understand, but for coming in 103 instead of 105…nah. Perhaps that is why Mr Froome had all that salbutamol in his system…to stop any need for a toilet visit.
