Have done a couple of long rides recently on my old BZ (Before Zinn) bike. Was an interesting excercise.
I've got a bike in my garage that illustrates the proportional length crank philosophy that is one of the cornerstones of the design philosophy of Zinn Cycles. It's not a Zinn bike - but even so - it's still pretty cool...
If you’ve ever done squats in the weights room – you’ll know that you can cheat by not squatting all the way. You can seemingly lift more weight – but it’s a false economy as you don’t get the full strength gains that a deep squat can give.
Kieran Cox is a long time Zinn Cycles customer, and advocate of proper frame design and crank length for tall riders. Here is some interesting data he has developed with our custom cranks.
