I have a pair of superstar evo wheels, bought this item along with the 10 mm thru axel as I snapped the qr version. The part was extremely easy to fit and looks really great. This part will stiffen up your rear end. It makes your rear wheel a snap to take of or put on. Great value product and fast delivery. You won't be disappointed so upgrade now. P.s this will fit standard qr dropouts.
I'm on about my 4th pair of these in different colours and lockrings. I've looked on crc and other sites for a comparable product, but you'll pay at least double for anything like. These really are superb forvthe money and loads of choice. I've sent many friends down to buy their own as they're so good.
Great product, fitted perfectly with the help of the spacers that were supplied. Alignment is spot on, product's well made, fast delivery and great price. Was on a 2010 trek scratch if that helps you make the decision to buy one for yours!
