KR 12mm hex wheel system on a SV2
 

Hi there
just been testing my SV2 with the KR hex wheel set up front and rear.

I could not feel a big difference on the read but the front is much better having the wheels tight so that the chamber is much more consistent.

I found with the conventional front wheel after a short time the wheel comes loose where the bearing fits in the wheel, with the hex this does not happen.

A good up grade if you are at a point where you are about to buy new wheels, which was where I was when I decided to go for the 12mm hex system.

I found the J-Concept Rulux front wheels are more loose than Schumacher wheels too. Also change bearings more often will help too.
