I realise this could be thought of as cheeky/plain wrong to post this here..but I figuered the ones that would be best able to help in this situation would be hanging around this forum!!
So here goes....
Ive been training and racing for about 4-5 years now and its been a roller coaster of trying to find my optimal position (like lots of people I guess),
anyway one thing that has stayed constant in all of that time is my crank length 172.5. Now Ive decided to go over to compact cranks (no....nobody try to talk me out of that I have my reasons , namely 5000m climbing in one day race on a gruelling tour stage).
But over those years Ive heard alot about changing crank length in larger steps ie, 5-7.5mm like form a 170-175 or 177.5 but not so much about the 2.5mil difference of changing from one to another. I want to change over from 172.5 to 175's as its worth an extra 5watts (everything else being equal) and more leverage on these long steep mountainous climbs I have in mind.
Ok so its a bigger deal changing from say a 170-177.5........but
Bearing in mind that Im finally close to 'dilaing in' my position on the bike right now close to optimum , should I try and make a change to a 2.5mm longer cranks?? considering a 5 watt increase and slight decrease in cadence is usefull to me???
any thoughts??
cheers.
