Rear mech hitting spokes issue

Right, classic issue, on my 8-speed shamals when in the largest cog my campagnolo record deralier collides with the spokes! the mech isnt bent and the limit screws are correctly adjusted, I am at a loss as to why this is happening! surely a record rear mech would be compatible with a set of shamals? both are early to mid 90s... maybe i need a more streamlined version of the rear mech.. who knows. Any ideas would be greatly appreciated as i'm currently running it as a 7 speed with the limit screws adjusted to block the 8th cog due to the rubbing! thanks

gear hanger is bent, you need this

Mine's doing that too, haven't got around to trying to fix it yet as I've only had the bike running for a few days...
8-speed Ventos, rear mech is 2nd generation C-Record...

gear hanger is bent, you need these.

You're bent, you need this...

First case, sounds like a bent hanger. Second case, could be that, bent mech, or poorly tuned mech. Sort your shit out, Joe. Or else I'll take the bike away from you for treating it badly.

Funny you should say that, the front mech hanger was actually bent... Jim had to get the hammer out...

blocking 8th cog? You're blocking your 1st cog. I'm making the clarification because i want to make a point, below.

If you're blocking your 1st cog with the limit screws, be sure to leave the extra cable in the "9th" position so that you can only over shift to a "too lose" cable and not too a "too tight" cable. this is especially important if you're using a newer indexed system as you can not only place a huge amount of stress on your derailleur by over shifting, but also fux up your shifter.

anyway, if you're blocking the 1st cog and it's still fucked, you have a bent system. Either the derailleur or the hanger.

take it to a shop and they'll use the every overpriced tool posted above to sort it out.

At least it wasn't the front mech that was bent! ;)

And the rear?

First case, sounds like a bent hanger. Second case, bent rider.
