cutting up my wh-535's(11 posts)

cutting up my wh-535'sandrossmazor

I have the shimano 535 wheelset, and there is this black plastic protector on the rear wheel to keep the chain from falling behind the cassette. That is something that has never happened to me on my road bike before so i dont know if this thing is neccessary. I would like to cut it off because it rubs against the rear derailluer when Im in my largest cog. So is it ok to simply cut this thing off? Andew
Don't cut it off...........Dave Hickey

Take your cassette off and remove the plastic protector. It will pop right off

Please don't take offense to what I'm about to say. If you're not sure how to properly remove the plastic protector, I wouldn't take it off. The problem you are having has nothing to do with the plastic protector. Your rear derailluer is not adjusted properly. Your limit srew needs to be adjusted. Until you're more familiar with the mechanics of your bike, I'd leave the protector where it is.
Once you are comfortable with derailluer adjustments, removing the protector won't hurt a thing. Having a chain suck into your spokes is no fun and can be extremely dangerous.

Chainsuck happens at the chainstay. A properly adusted deraileur will not throw a chain into the spokes. And yes I have seen the 105 wheels with spoke protectors that bulge out and the cage of the rear deraileur will rub on it no matter how well it is adusted. The other common wheel with this problem is the Mavic cosmos wheels that come on the 2001 Cannondales. Same problem with rubbing.

It's there for a reason. If that wheelset is anything like Mavic K's, then that area will get chewed up badly if the chain gets in there. I have a friend that didn't use the protector on his K's, threw the chain and it really did a number on the hub. It's ok, but chewed up really bad.

Leave it there and do some derailleur adjustments.
if the it rubs the protector now...PdxMark

will the derailleur be in your spokes when you remove the protector?
an excellent point! nmjose_Tex_mex

no, it is about a half inch beyond the spokes...androssmazor

at the point where it is rubbing and is all warped cause it's cheap plastic... and because it's warped it doesnt constantly rub which is why i didnt think adjusting the derailleur was the right thing to do. But i'll try that now. Andrew
Well now, hold on ...scottfree

I wouldn't go off half cocked jacking around with your deraileur adjustment just because people who haven't seen your bike tell you to on an Internet bulletin board! Geez. If it's a half-inch beyond the spokes, your problem indeed is probably the cheap, flimsy, warped CRAP they use for spoke protectors these days. It's common for them to rub on properly adjusted bikes. And the problem is intermittent because the things flop around. And since it IS so cheap and flimsy, feel absolutely free to cut it off wthout removing your cassette for 'proper' removal. Sheesh.

Ok, so with more information, it becomes easier to give reccomendations.

I still stand firm in my belief of not just tossing the thing altogether. I would however take it off and try using a heat source, like a blow dryer, to mold it a bit more straight. It may take more heat like that of a real heat gun, but you'll know what works and what doesn't.

Yeah, a properly adjusted rear derailleur SHOULDN'T throw the chain past the large cog. Then there's the one time that something out of the ordinary happens. Sorry, I like my non-chewed up hub too much to take the chance.

I'm not a spokeguard Nazi. My retro bikes have good, substantial spoke guards on them, and I've left them on because, as you say, you never know. My 'modern' ride, however, came with a floppy, ill-fitting POS that felt like it was made with a couple of layers of Saran wrap. It wasn't warped per se -- it shape-shifted because it was so flimsy. Sometimes it rubbed, sometimes it didn't. It was all over the place. Nothing anyone could do would fix it, and I cut the bastard off with scissors no sweat. I think that's the problem this fellow has.

BTW, I think cheesy spokeguards are sort of like the cheesy reflectors new bikes come with -- the manufacturer just puts them on to satisfy safety rules, knowing full well the buyer's going to jerk them off the minute he gets home, so they're really, truly disposable PsOS.
