Title: Any body shine any light on this??
Post by: VWmk2 on November 30, 2011, 10:35 PM: Recently got hold of a GT Dyno that's had the frame powder coated (which I thought was causing the problem below but after further investigation I think not) and was having problems with the rear wheel moving forward under tension causing me to whack my shins on the pedals after the chain was coming off :angrysoapbox: :D

I whipped the BMX upside down to re tension the chain and tighten the wheel back up and found that the right hand side drop out (looking from the back of the BMX) is slightly bent

You can see a slight bend at the place of the axle

This is the left that's much straighter

I didn't notice it was bent till I tried to take the wheel off but couldn't because of the bend!!

Is this normal lads ? Im not to clued up on wheel widths so if some one can educate me fire away :daumenhoch:

I think the slight bend may be causing the wheel bolt to not tighten flush with the frame and there for wont be getting a nice grip/hold causing movement, kind of the same reason I thought the powder coat was to blame as its scuffed and gouged out

One more thing, i don't think i can tighten the bolt up any more as they feel as if there going to strip the threads :(

Any advice is much appreciated

Post by: thecrooch on December 01, 2011, 11:15 AM: single bolt are better than double... Profile are good but bloody pain in the ass to fit with double bolts. loads on fleabay only thing you need to know is if the axle is 10mm or 14mm.
