Abbey Bike Tools Single Sided Crombie Tool

Ok, kinda expensive but it makes cassette work that much easier. And it's made from quality steel. I bought this because my $5 Park cassette tool cracked. No more fumbling with separate cassette tool/ wrench. Surprised Park didn't come up with this design!

The adapter i used to use is now resting in the toolbox, this is perfect, one tool does it all for cassette or center lock.

Changing cassettes is traditionally a frustrating balance of wrangling a lockring tool, wrench, and chain whip with just two hands without also getting injured by the sharp-toothed object you're trying to work on. This tool kicks those worries to the curb and just makes sense. I'm not sure why more tool companies haven't switched over to this type of design - it makes cassette maintenance a breeze.

I clean my cassette about every 1.5 weeks by taking it off and putting it in a ultrasonic cleaner. This tool makes it so easy! I use to fumble a lot with the wrench and the cassette removal nut...no more!

I got tired of borrowing one of these on the not to often occasions I was changing out a cassette. Way less hassle to own one and this one has worked very well in the 7 or 8 times I've used it.

You don't need to carry around an adjustable wrench to unlock your cassette like most of the "nut" style tools. The Abbey also gives you great leverage when loosening and tightening your cassette.

The quality is unreal. Works great and using it is awesome.
