Having a big pair of bear paws for hands is a great bragging point and can be quite an intimidation factor when it comes to shaking hands. However, unless you're some kind of political figurehead, you probably don't spend hours constantly shaking hands with other people and therefore don't feel the fatigue associated with such actions.
Yeah, I know, where am I going with this right? Well, shaking hands is kind of like pulling in the clutch on your bike, except your hand is more parallel to the ground rather than perpendicular. And unlike shaking hands you're bound to pull your clutch lever way more often and exert more effort in doing so, especially if you have a heavy clutch. Such was the case on one of our Softails. We had recently upgraded to Barnett's new Stealth Series (blacked out) cables. Even though the new clutch cable featured Barnett's HE (high efficiency) inner wire which aids in smooth clutch pull and reduced effort, our "cleaner" (look-wise) routing method put a tight bend in the cable coming right off the clutch perch which made it a little tougher to pull in the clutch. It wasn't unbearable, but we knew it definitely could be improved with a quick installation of a Power Clutch kit we picked up from Eurocomponents.
