I like clips for the feel. I like the foot position, ease of manipulation, easier technically climbing, no-slipping etc. "Extra power" really isn't a consideration

Spoiler alert: enduro and downhill guys don't wear them for pedaling efficiency.

Losers. The "synthetic image" is nothing of the sort. It was created by Don Eigler's group at IBM in 1993 [M. F. Crommie, C. P. Lutz, D. M. Eigler, Science Vol 262, p 218, 1993], and has...more

Powerbands for bikes! Looks like complete BS.

What matters is the time on the clock. Nobody forces you to buy this bike. But, any rider, at any lvl...more
