overall, im very pleased with my new Scott Sub 10 foul-weather/back-up commuter,
but the single hand position flat bar, with its hard-as-steel, "el-cheapo supreme" grips, isn't doing me any favors. even on my short little 15 mile commuting runs, i'm getting hand numbness. for comparison, i just completed a 900 mile LEJOG tour of great britain on my road bike (where even more of my weight is on my hands) and didn't experience a single moment of hand numbness or dismcomfort on the entire trip. putting weight on my hands is clearly not the issue here.
my old back-up commuter had bullhorns which i absolutely LOVED. i could ride forever on those bars with nary a bit of hand numbness/discomfort. i've thought about putting some horns on the new steed, but the hydraulic disc brakes levers and alfine shifter mean that i need bullhorns with a 22.2mm grip diameter, which are proving quite difficult to find. as an alternative, i've heard good things about Ergon grips alleviating hand numbness issues for many riders. then i saw the Ergon GC3s, which have extra long bar end extensions, and they look like they might come close to giving me a similar feel to being on the horns of my old bike.
does anyone have experience with Ergon GC3s? can anyone speak to how close they might come to giving me the "on the horns" feel of a bullhorn set-up?
or should i not bother with them and just keep searching for the rare and elusive 22.2mm grip diameter bulhorns?
other suggestions are always welcomed as well, of course.
