The best upgrade you’ll make.
Going to a single ring can be liberating. And it's easy, you simply strip the unnecessary parts off your bike and go ride. It'll be lighter, and you'll be sure that it's more awesome. The only thing you're going to forget is that your existing chainring bolts will be too long to tighten fully on a single ring.
At that point, you'll be searching desperately for washers that'll take up the extra space even though you know they'll distract from your bare bones aesthetic. Chances are you'll find three that match. Your next move will be towards the bench grinder with female bolt halves in hand. Don't forget the vice grips, unless you need to trim your fingernails too. This sound like a disaster? Situations like these inspire the folks at Problem Solvers. They experience pain and frustration then create something to make it all better. This Aluminum Single Chainring Bolt/Nut Set is just the thing you'll need for your new single ring set up.
The Problem Solvers Aluminum Single Chainring Bolt/Nut Set is black and comes as a set of five matched male/female pairs. They're short enough to fasten a single ring onto your four or five hole spider. The female nut is 6mm deep.
