Question about horizontal dropouts problem

[orange71]

got it

 

[messiah]

I've got the DMR's on two bikes - I had to drill them out to get Hope axle's to fit in but once that was done they are both perfect.

With horizontals drop-outs, I just use the old heavy Shimano QRs and do them up really tight!! I also use those cheap & colouful Halo allen bolt ones you can get on eBay for about £9, but I think these QRs are tougher (and more retro!). Another bizarre bodge was to cut off the plate from a cheapy old SIS mech (for horizontal frames without a hanger) and fit them behind the axle, but that limited my chain tension adjustment range to 0mm

might try some of those qr's till I get hold of tugnuts

 

[bojangle]

the only way I've got round this is by using all steel Q/R and doint them up as tight as poss.

Chain tugs DO NOT WORK, they are designed for single speed. They work by having three forces at work,
The two chain tugs and the chain back. With gears the chain is not under tension so the lugs are not pulling the chain back but preventing them to go forward, the chain stops the wheel going backwards.!! :?

If you have horizontal dropouts with a rear mech and chain tugs, only one side will stay put the other side will move back!

I have the same problem on my DH bike, i spent some money on a decent salsa qr and did it up feckin tight.

simples!

sorry should have made it clearer - I am running singlespeed

 

[bojangle]

aaahhhhh :roll:

Ignore everything i said before, get some chain tugs

If you want to simplify things you can just run a tug on the drive side. Saves a little bit of faff.

yes , having one on the left is basically a waste of time . When you put the wheel back in pull on the chain and it'll snug the tug nicely against the end of the dropout , tighten that side if its not a qr and then make sure the wheel is centre and do up the left .

tried the shimano qr trick last night and it was much better - may try it tighter still before going down the tug route.
