    Chain tensioners and disc brakes

    So i installed some elixir 3s on my single speed, and i am having a problem with the chain tensioners. I tension the chain perfectly, and straighten out the wheel, but whenever I pull the rear brake the wheel moves backwards only on the brake side of the wheel and the tire rubs against the frame and my rotors rub. Can anyone help me?

    Are you using bolt on or qr rear hub? I run a tensioner with Hope disc brakes and a bolt on hub on my Bianchi and I have never experienced the problem you described.

    Well if you want the strongest clamping skewers...then yes. I just got a set of XT skewers on Ebay for $15 shipped. I haven't had a bit of slip and I don't even use a tensioner on my brake side

    I thought the chain tensioner would keep the wheel from pulling forward? But looking at your pic, it looks like the QR isn't all the way forward in the tensioner slot.

    My tensioner is a chopped up home made deal and I have my chain very short.

    When you get the skewers...take the brake side tensioner off. Let the teeth of the skewer bite into the dropout, that's what holds it.

    This is the best way to straighten the wheel when locking the skewer with no brake side tensioner, I've found.Adjust the chain side tensioner until the chain is almost tight (this will pull the front of the wheel towards the chain)...then grab the front of the wheel behind the seatpost tube and pull towards the brake side until the wheel is straight between the frame...hold it in that position and lock the skewer. Done!

    This method has always worked for me. Don't be afraid to scuff the dropouts with the skewers...if you want it to hold LOL. Also when straightening wheel...it will pull the chain tighter...so pull the wheel and loosen chain tension if needed before locking the skewers.

    Any other ???s, just ask.

    alright so I swapped my FSA skewers with these shimano ones that were on an older bike. They work perfectly! The wheel no longer slips backwards when you pull the rear brake.

    Awesome! Shimano skewers are a must on these dropouts. I'm still a fan of only one tensioner though...quicker to remove/install wheel with only one. That's my opinion though LOL.

    Ride on!

    I thought the same? On the rear wheel, the disk brake should pull the wheel deeper into the dropouts. If the chain tensioner is pulling back, the wheel shouldn't be able to move.

    I noticed disc brakes can over time very slowly pull even a bolt on wheel back. Make it super tight.

    Nice! You can definitely feel the difference in clamping power when using shimano. And I believe they look much more classier as well.
