    14g home made chain guide

    Nice work !

    How stiff it is in case of heavy chainsuck or dropping the chain and back-pedaling ?

    Seems to work OK. Not dropped a chain yet! Still some further room for adjustment too.

    I really like this. I will be checking my parts bin. Especially timely for me, as I will (hopefully) be putting together an 1 X 10 XTC build this weekend.

    Nice, I bet you could almost sell these.

    It's something i've been playing around with for a while - i always knew i could use a seat clamp and alu bolt but had to do some trial-and-error with the actual chainguide part. If it starts failing and i can't adjust it and get it to work, i can always buy the actual bit from Superstar Components and modify that to fit.

    I sort of based it on the Helium one as i liked the design but i'm not paying what they're charging!

    Lol, it's nice work, but it is too butt-ugly to sell to the public. It's good and innovative as a do-it-yourself project though. Nice Job!

    To each their own. Looks quite nice on the bike. The actual guide bit is the only bit I'd change aesthetically - carbon clamp and alu bolt/nuts look cool.

    Or you can just get one of the many rings (like Wolftooth) that don't need a chain guide. Hey, you'll save 14g

    Would I not require a different rear mech for that? They don't work with non clutch 9 speeds so I'd need new mech, shifter and cassette (chain is already 10spd). Hardly cost effective. I'll stick with the chain guide.

    It's just a chain ring so of course it doesn't need a specific derailleur. I guess maybe you meant they don't fully do the job without a non-clutch derailleur?

    FWIW I have a Zee mech on my bike, with SRAM 9speed shifters, so you don't necessarily have to go to 10s to use a clutched derailleur. Itt's surprising how much chain noise it eliminates.

    Yeah I meant they're not supposed to eradicate chain drop without a clutched derailleur so wouldn't stop me needing a chain guide.

    I clearly said for a home-made rig it looks fine.
    As an engineer, I'd question it, if I saw it for sale in a package. It looks like a pieced together home-made rig. The exposed hardware by your ankle would be an engineering no-no.
    I'm sure it works just fine. No need to be offended by my comments.

    No worries - I wasn't offended. You said it was butt ugly and I was just saying it actually looks OK on the bike.
    I appreciate your feedback.

    I'm actually going to refine it and change the guide part. Not 100% sure what for yet but I have a few ideas floating around.

    What do you think of the helium one?

    Re: 14g home made chain guide

    Made some changes which have stiffened it up immensely. Have modified the actual guide section. Also decided to remove the logo from the clamp to make it a bit more plain.









    Sorry about the crappy pics!

    Had a few good rides on it now ad have yet to drop a chain. Once I'm 100% happy with it, I'll tidy it up.

    Can you give us some follow up on this chain guide? My experience with similar designs that do not have some method of trapping the chain inside (like a FD cage does) is eventually you WILL drop the chain and it will be impossible to remount it on the chainring without loosening the guide, sliding it away from the chainring. I ended up taking the cage off a FD and mounting it in a similar fashion to what you have done. Yes, ugly but functional and inexpensive...and it will save you the experience of having your chain drop at the worst possible moment in that big race.

    I am curious...on the inside of the guide I do not see a nut...how do you keep the guide from slide on the bolt or it that part of the design?

    Still yet to have dropped a chain with it.

    You're right though, if it dropped, it'd be a pig to get back on. Luckily though, I've not had that problem yet.

    There's a nut on the inside but it's set into the guide so you can't see it in the pics. The two black guides that go either side of the chain are threaded also, which stiffens it all up a bit.
