Trying to get a little more info on this - can someone tell me if the bolt takes a 3mm or 4mm hexallen key? Don't want it if it's 3mm, likelihood of it stripping seems higher. Thanks.
Cant do synchro shift without this battery, and its worth the upgrade just to get synchro shift. I'm not a lazy shifter but it is convenient in a race to not have to think about the gearingcross chaining as you meet hills. Just shift!
