Looks like these days you have two choices...
PN H50140 that's got shanks which are the same diameter from the root to the ends
PN H50140B whose shanks are necked down at the end to a smaller diameter.
Pick the one that works for your grips, bearings, and other TR parts.
Too long is a relative term. You're probably talking about 2-3 mm length difference, which in the grand scheme only increases your TR diameter by that amount. Nothing to lose a lot of sleep over.
