chain ring guard
 
I own a bike with a Gates belt instead of a chain. When I ordered the bike I didn't think I needed a chain guard since there's no grease involved.

Well, every so often, if I'm not paying attention, a shoe lace or a baggy pants leg might find itself between the belt and the teeth on the chain ring. I went back to my bike shop and they ordered a chain guard for my bike. It came in but there wasn't enough clearance.

One of the older guys who works there came back with a less expensive and more elegant solution, a simple chain ring guard which they had in stock (though the one they tried was just a tad too small).

Instead of looking like ... http://img.diytrade.com/cdimg/112977...hain_cover.jpg it looks something like ... https://encrypted-tbn1.gstatic.com/i...RXktYxVNKn4Gug and just covers the belt at the chain ring area.

They didn't have the exact size I needed but they ordered one for me that will do the trick. I wish I would have thought of this myself. The price for the originally ordered guard (a pressed aluminum guard though most are made from plastic) was around 30. The one ordered will be around 10.

I should add that I have an excellent relationship with my bike shop. I know the owner and all the employees. When they work on my bike I always get a loaner and if they're out of their loaners, they'll give me a bike someone traded in.

A simpler solution if you must ride with baggy pants is to keep an ankle strap on the bike, you can store it on the seat stays if you don't carry a big enough saddle bag. You can also tuck shoelaces under themselves to prevent them flopping around, or better yet wear laceless shoes.

Yea, I have plastic and metal clips that I always forget to use. They work great on clothing but shoelaces are still an issue. :)

I had the Image of the belt stuff encased, to not call attention to itself, when parked in town, locked up.

knowing traditional Dutch chaincased bikes just dont get chains oiled enough, it seemed a good match ..

But the gram counters predominate .. when you put out that kind of money..

by using longer bolts you can put a de toothed chainring on the outside.

Schlumpf makes big disc rings .. I have 1 on my 54t Mountain drive crank , ditto Bike Friday, with a a 53t.

Cyclocrossworld . com got a batch made, they sell , no purpose in over 44t for the single ring CX race crowd.

Big wheel small chainring I got a 110 bcd for the 38t chainring on my 26" wheel R'off bike.

Bookmarked this , no experience with product. .. http://bbgbashguard.com/


Perhaps someone in Country can fabricate a wire frame and sew the Truck tarp cover for the frame
to do a traditional Oma/Opa type chain-cover for your needs .

Bob, I'll assume the bike shop will have no problem ordering what I need from their supplier. The chain guard they had in stock was one size too small.

I took a look at the link you provided and I couldn't find a chain guard that would work with my bike; of course, it's possible I overlooked something that would work.

The diameter of my front ring (with the belt) is about 8" or 120mm. The spacing of the mounts, I have a four arm ring, is 74mm ... and I've learned online that is 'Shimano'. (The other number I saw online was 104mm I believe.) The number of teeth is 54 though I don't know if the number of teeth translates to the same number if I were to have a metal chain instead of a Gates belt.

At any rate, I think I managed to find only one chain guard online. The guy at the bike shop was pretty certain he could order the next size up from the item they had in the store so I'll leave this for them to sort out.

I really don't need a 'full sized' chain guard, I just need a guard at the front ring since that's where the issue is.

4 bolt suspect is 104 BCD you might try SJS Cycles in UK Thorne Bikes is theirs

they get a 104 bcd 4 bolt chainring, 32 up to 50t, at the usual 0.5" pitch

Trouser-leg stuffed in my socks is my style..

A follow up ... I received an sms from my local bike shop today informing me the part came in. Here's a link to what they ordered ... XLC : x-cellent Components

It gets mounted in the center of the crank set and uses a one size fits all arrangement. As you tighten the screw it expands a thingy on the inside. It seems very secure though up close it looks like cheap plastic. It's extremely unlikely that I'll find a way to break it.

It sure is nice now to not worry that a shoe lace or a pants leg gets caught in the belt.

Yeah that is a nifty solution. I would also suggest if you are commuting and dressed for work a big rubber band also does the trick and even simpler is to put your pantleg into your sock....

Max, over here most folks use some variation of this ... (and I have several) ... Halfords | Halfords Reflective Bicycle Trouser Clips

For shoelaces, it's just a matter of tying them correctly to stay out of the chainring. Here's what I do:

Tie a bow normally.
Gather up both loops and the tag end that's closest to the chain into a bundle, and pull them to the outside of your foot (away from the chainring.)
Take the remaining tag end (originally away from the chainring,) and wrap it around the bundle, securing it by going through the loop (half-hitch.)
Now, everything hangs away from the chainring. The longer your laces are, the better this works.

Or, simply tuck the laces into the shoe.
