TheoG Posted October 19, 2021 Share Very noticeable that the SA ladies are doing very well, plenty of representation in the top ten teams, well done so far ! Hairy, Scary Rider and ChrisF 3 Link to comment Share on other sites More sharing options...
DieselnDust Posted October 19, 2021 Share 20 minutes ago, Sid the Sloth said: The difference between the 10t and 11t is quite impressive. Running a 38 11 is similar to a 34-10 (3.45 vs 3.4). Running a 36-10 gives you almost the same ratio as a 40-11. I have found the move from 11 to 10 on my gravel bike pretty impressive, and I was considering moving up a chainring size before but now I am pretty happy. Now don't get me started on the drivetrain inefficiencies of running a smaller front ring or a smaller cog on the back... forget about the drivetrain inefficiencies. That's so small its only noticeable to snake oil salespersons ChrisF and Sid the Sloth 1 1 Link to comment Share on other sites More sharing options...

That's so small its only noticeable to snake oil salespersons Well if they are running 55t + chainrings in TT's partly to stay in the middle of the cassette, and people put on OSPW, wrapping your chain around a 10t and having a small front ring does not sound like the optimal combo. You are right though it is probably only milliwatts. J Wakefield 1 Link to comment Share on other sites More sharing options...
DieselnDust Posted October 19, 2021 Share Its more the straightness of the chain were there is additional friction losses but I think unless you are addressesing all other friction losses the chain wrap over a 10 is nanonwatts and a watt is a small number Sid the Sloth and J Wakefield 2 Link to comment Share on other sites More sharing options...

Believe it or not; that 1w over 4hrs is a fairly big loss of time when calculated and power. 1 of the reasons we had Tadej run a junior cassette at the Tour TT last year to eliminate any cross chaining Bos, Scary Rider, Sid the Sloth and 5 others 8 Link to comment Share on other sites More sharing options...

On a road bike I apply the same. What gears are used mostly so what chain rings allow that while keeping the chain as straight as possible most of the time J Wakefield 1 Link to comment Share on other sites More sharing options...
