Last couple of months I have been riding my 27.5 Muni with a road tire because a lot of tracks were too muddy to be any fun.
When I switched the tire I also changed the crank length from 136 to 110 mm to speed up my rides.
This is my first time riding such "short"cranks.
It took a little getting used too but soon I could comfortably ride with them. Even climbing is not too much of an issue.
But on the steeper slopes I noticed something :
WHen the going gets tough, standing up doesn’t seem to add much to the climbing ability.
But with the 136 cranks I can feel a clear benefit.
On the 24" there is also a difference between 125 and 145 mm cranks but there is still a big benefit when standing up.
With the longer cranks you really get the “stairmaster” experience and power your way up.
I don’t think it is really a gain* issue, to me it feels more like at 110 mm the stoke / steps are just getting too small to get extra benefit
What are your experiences?
Note: I’m not talking about a small / short incline than you just tackle at high speed and rely on momentum.
