Cyclingnews and VeloNews *f##k* up his bike stats and measurements
Canyon, size 56: http://www.bikeradar.com/gear/article/p ... -cf-28966/
15mm of spacers and an 8-10mm headset cap. 120mm stem.
555 stack, 396 reach.
BMC, size 50:
140 stem, slammed
530mm of stack, 376mm reach
This suggests that his bars were about 25mm lower on the BMC and questionably the same reach, probably less. The 3T bars he is on are also deeper.
The BMC is actually A LOT shorter, which is why you saw him change frames mid way through the Tour to a bigger size and 40+mm of spacers underneath the stem vs. slammed on the headtube. At one point his stem was flipped up on his WC bike but they changed it the next day.
If you take that amount of spacers into account and the long stem, he could easily go a full 2 sizes up and run a 120 and still need a few spacers. According to my stack/reach spreadsheet if he had the same seat height and setback his super small BMC actually had 4.5cm more drop.
Fit plays an important role into mechanical efficiency. I've seen it in myself and other riders, but there are some curious cases in the pro-ranks too.
Contador's fit has changed and he looks noticeably worse and performs worse, especially since they switched his Shiv sizing around in TT's. Watching him climb seated is absolutely painful. He slides all over the very nose of the saddle and bucks his hip with every stroke.
Sky bring in fitters at every single camp to asses changes from injuries or weight loss/gain. They seem to always look good/comfortable on the bike and are very efficient.
Boonen stopped having back pain when he changed his fit when Speci came on with OPQS.
Cav is famous for changing his seat and bar position daily depending on feel.
Greipel moved his bars up and out when Lotto went to Ridley. He started winning more sprints and sprinted with a slightly lower position.
There have been a lot of riders with documented position changes over the years that have helped mitigate injuries. Gilbert has never been that flexible or had that straight of a back and most of his bikes actually had quite a bit of stack so its weird that BMC pushed the slammed fit.
Don't take me too seriously. The only person that doesn't hate
