Gear Specific PRs
I spend my cycling time split 50/50 between a road bike, and a mountain bike, and am often on the same roads and routes on both.
It'd be nice for PRs to be gear specific, so that I can see improvements on my mountain bike.
Currently all my PR's are on the road bike (obviously!) and there is no real way of noticing improvents on the MTB.
I expect many other riders will have similar differences between gear, whether its single-speed, TT bike, or 29er etc.
