Chain guard to protect my pants



I inherited this bike a few days ago, and am currently using it replace my ****ty Magna girl's bike I had been using to commute between home and work. In every way, this bike is better except for one thing: there is nothing covering the front chainwheel.

This sucks because if the chain is on the smaller gear, the top gear's teeth stick out and get caught on my pants, which is REALLY annoying. If I put the chain on the top gear, the teeth are covered by the chain, so no catching, but instead I get chain grease all over my pants let.

There has to be a chain guard I can buy that fits over the front gears, but I can't find anything. I've searched all online bike shops, but can't find anything. Does anyone know of a solution to this problem?

You might not like it, but my solution is shorts :-)

Other than that, I think they make some big rubber bands that you can put around your pant legs so that they don't get caught in the chain. As for an actual guard, I don't know.

Roll up one or both pants legs.

To be honest, though, I'm more worried that there doesn't seem to be any bolts holding the chainrings on.

Have you tried velo-orange.com? What they've got isn't a full chain case like is on an Amsterdam, but I suppose it's better than nothing. Don't know how easy it's going to be to make a chain guard work on a bike with a front and rear derailleur rather than hub gears.

My bike came stock with what I have scientifically named a "chainring protector thingie" and it does a good job of keeping my pant leg from coming in contact with the mechanism. I don't know if you can just buy one by itself and slap it on there, or if you have to get a whole new setup. Maybe somebody on here would know or you could ask at your LBS.

Also, get some reflectors or reflective material (white or yellow) on those pedals. In California it's the law if you're riding in the dark. Dot C2 tape is cheap and works great. It should be available at your local auto parts store.

yeah, thats exactly the kind of thing I'm looking for. My old crappy Magna I bought at a garage sale from a 10 year old girl (I kid you not) that I rode probably 12 miles a day for almost a year had a chain protector just like the one on your bike and it worked perfectly.

I've been looking and looking, but can't come up with anything. A few days ago I tried making a makeshift one out of cardboard from a cereal box, which worked fine for a while, but then it rained and it began to fall apart.

Velo Orange has some. Not sure if they'll work, but worth a try.

Hebie chainglider

Any bike shop and or dept. store sells pant clips for acouple of bucks. In a pinch I cut a rag in one inch strips and tie it around my ankles. Even with a chain guard you get grease on your pants.

Real chainguards (not those little disc things) are tough to find for triples, and probably a huge fiddle to install. The Hebie Chainglider will work only for singlespeed or hub geared bikes. Hebie does make chainguards for triples, and The Urbane Cyclist in Toronto, http://ucycle.com/accessory/item.php?name=hebie_intro , may be able to help you.

A bicycle upon which one may ride while wearing a $2,000 suit seems to be beyond the grasp of American technology, with a few exceptions like Breezer. I think the best solution is to shell out some money for a new bike more appropriate for practical use. On the other hand, your current bike has the great virtue of being free, so one could reasonably expect to tolerate some problems with it.

AS others have suggested, a pants clip, rubber band or an elastic strap. If your really concerned about damaging a nice pair of dress pants, a simple solution is to make yourself a gaiter.



Get a really big sock and cut the foot part off, or maybe cut the bottom leg portion of a pair of to small sweat pants. Pull this on over the pant leg.

SKS, makers of the chromoplastic fender, make several styles of chainguard including for triple chainset.
I use a simple springy metal trouser clip.

The only full chainguard I've seen on a front deraillur bike was on an 07 Specialized Globe. The bike shop could not order them for other bikes. I looked far and wide for a full chainguard with no success.

I ended up spending hundreds of dollars to get a Hebie Chainglider and switch my drivetrain to a single front and internal geared rear. This works well, but it isn't worth the $$$.

Tuck your pant leg into your sock, put a reflective strap around your pant leg, or try to find one of those big rings to just protect your pants from the chainring with mixed results on protecting you from the greasy chain itself.

Also, try a couple local ike shops, they might be able to rig something up for you. good luck adn please post whatever solution you come up with.

A full chaincase is going to be all but impossible to find for a triple, but you may be able to rig a partial chainguard to work.


The image is linked back to where I found it.
They are cheep enough that experimenting would not break the bank.


Sögreni makes one that I think is elegant and could be put together in a good hardware store.

Use a strap around your pant leg. I probably get my pantleg dirty 2-3 times per year, if even that much.
Keeping your chain reasonably clean will help too. I probably degrease and wax the chain once a month.

A sock, if available on your right foot, makes an excellent place to tuck a flapping trouser leg.

It works for me every lunchtime!

I sell a few chainguard models including the Hebie Chainglider but unfortunately there are very few options for anything other than single chainwheel (ie your triple will not work)

I tuck my pant leg into my sock. I'm not very cool though so it's ok.

Ankle reflector straps do an excellent job. +1 on socks.

isn't it silly that there's no better solution? why doesn't someone make a chain guard that would fit a triple? is it really that difficult?

Hmm, you could try switching to wax based lube after degreasing your chain. It'll greatly reduce the stains from dirty chains. Haven't gotten a chain tattoo in a long while. The worst that could happen is some black wax residue sticking to your leg which you could just brush off. But I still second securing your pant leg somehow, don't want your pants getting caught.

Performance sells Schwinn World Avenue for $450.

It has a triple with a chainguard. But there is a cut in the chainguard for the front derailleur.

Unless you're wearing dress slacks or something just rollup the pant leg. Less dorky than tucking your pant leg into your sock


But yeah, before you even ride that thing take it to a shop and have them look at the chainrings.
