Whats the name of the plastic disc behind the cassette?

aquaaddict

Hi,

The clear plastic disc 'thingy' that sits between the inside of the gear cassette and the spokes on the rear wheel broke. I have cut it out but have no idea what its called to order a new one; the bike is a GT Aggressor XC2.

So any help on the following would be appreciated:
1) whats it called?
2) are there lot of diffferent sizes as unfortunatley / stupidly I no longer have the old one, 3) do I really need it / is it just to stop the deralier hitting the spokes if it travels to far?
4) are there stronger versions than the stock plastic ones?

Bit of a nuby so sorry if its an obvious question!

Many thanks,

Anthony

I broke one and never replaced it and had no problems with the mech hitting the spokes. Not sure if you can replace them (or if you really should)!

It's called a spoke protector. Only there to protect the spokes should the chain slip off the cassette. Which, if your mech is set up properly, shouldn't happen. Plus they look gash.

But I wouldn't bother TBH.

It's the first thing that I take off a new bike, they make it look like my daughters Halfords special!!
It goes in the bin along with reflectors and bell!!

mine half broke off on my first 'proper' ride (1/2 way round the marin) and was slapping the spokes making a chronic noise

dont know what its made of but bent it, pulled it pushed it, took a pair of pliers to it:: couldent get the remains off! eventually got a lighter out and set fire to it, melting its plasticky uselessness away.

I remember melting one of these off when I was a kid. Now I have a cassette removal tool and a chainwhip, it's easier, but less fun.

Yeah +1 melted one off quite recently. :oops: They make the bike look terrible along with the copius amounts of reflectors that go in the bin. Good job it was only on a crappy Coyote Vermont :evil: Which i got rid of recently!

Yep. First thing to do with a new bike is remove those and the reflectors IMO.

You really don't need one if your limit screws are set correctly. First ride out on my Stumpy a couple of years ago it decide to break (but not come off), jammed the back wheel and nearly had me off the bike. Still took another 20 mins with pliers mid ride to remove the bl**dy thing. Never again.

The one on my SX Trail broke off at the downhill park at sherwood pines.

Never bothered replacing it as the chain has never slipped off that site of the cassette.
