Bent Forks

Recommended Posts


landed my GasGas 300 pro in a hole and the force was taken by the front end (and my body :P .

On looking at the bike the front wheel now points towards 1 0'clock and the brace holding mudguard on is now bent/ snapped.

Bike still rolls ok but it's all skewed. Front wheel is not buckled.

Took wheel off, removed forks. Left fork is not smooth when compressing. Right fork seems fine.

Can anyone tell me how to check whether both forks are bent? Also, might there be damage to the clamps that hold the forks. They seem fine and there's no obvious damage to the frame. Any ideas on how to fix things or will forks need replacing.?

I have had this before with a road bike, I pulled the forks apart, so I could roll the stanchions on a flat surfave, I used a pane of glass and looked for a gap appearing along it's lenght as I wolled it, much the same as you would do with a snooker que to see if was bent on a snooker table, the forks are easy enough to pull apart, so don't be scared if you have not done it before post a question on here for more help with that.

I am not sure if the bike you have has one fork for the damping and the other for the spring as you do not mention the year (and I am really a Montesa man.... no spitting please), in which case, one would be easy to compress (the damping leg) and the other would be hard to compress as it has the spring in it so don't be fooled into thinking the legs are bent because of the ease of movement.

I would pop the forks back into the clamps but don't tighten them, don't refit the mudguard stay and see if the axle lines up correctly, you may need to compres one leg to get them lined up vertically, however you need to be more worried about the horizontal alignment, this will give you an idea if they are well bent, as the axle will be quite a way out.

also, look for any signs of visual damage on the stacnchions, they tend to crease if you have given them a real whack...

I hope this helps. :P
