Just been out the twice on them d.t.
Wasn't too sure when I first went out on them, not sure what I was expecting to be honest and I need all the help I can get on climbs (I got them and the cranks for a VERY good price so I couldn't really say no to trying them).
Went out for the second time last Sunday and I'm certain I could notice a difference when climbing………… 8O (after 50 miles in a howling gale)…………… I seemed to be accelerating up one of my local drags, that normally I twiddle up, without really trying, not sure where the speed came from.
