I have a Schwinn Boundary 2017 and it came with a quick-release front wheel. I noticed that no matter how tight I put the skewer it would be in a different position after extreme braking.
The bike shop guy told me that the fork is originally for a 10 mm bolt on axle with the splined washer that secures it. Sadly a front quick-release is as we all know 9 mm and rear is 10 mm. This front axle is allowed to move side to side under large lateral forces and the quick-release axle hits the bottom of the lip on the fork which is about 4 mm. Not a lot but it’s enough to offset the wheel in the fork by dang near an inch and makes it impossible to keep my front rotor aligned properly.
I shrugged it off for about a year then my pads wore to the bone and I replaced the pads and disks. I upgraded from 160 mm rotors to 180 mm and the axle now moves way easier due to more leverage from the rotor. The rear axle had a similar problem but just recently I used aluminum spacers and put them in my mounts to fill the gap between the axle and frame. It has worked for the back, it no longer has movement or at least an unnoticable amount.
I did the same with the front... only it made the front even worse, it just made it move easier and pulled the greatly bonded epoxy holding the spacers in.
I wanted to know if anyone else has had this problem, if there's anyway to fix these two axles because im about to get some grippy Maxxis Minnion DHF tires which will add to the problem and I would like to fix it before then.
