Chain Guides

iainstark

Hi was wondering if any one could help me cause i am not sure what chain guard to buy for my kona hardtail... Please someone help me

Guard (i.e. bash guard) or guide?

Why do you need it?

What crankset/chainrings do you have?

Does your botton bracket have ISCG tabs?

I'd like to know the same, doesn't look like there is any place to fit it on my 2009 Caldera frame. I'd like some kind of device to stop the chain from jumping off.

Clarify...
How many rings are you running...what BB?

cooldad

Chains don't just jump off. The front mech is a guide, the rear mech is a tensioner.

i need a guide for it because when using my rear chain rings when trying to go into my top gear it comes off and the same for the other way.. i run a single speed front truvativ crank. my botton bracket does not have ISCG tabs

cooldad

Comes off at the front or back?
Back set the limit screws on the mech properly.
Front stick an old mech on and set the limit screws for one ring.

its comes off at the front and was just wondering if i could get a chain guide on the bike instead of an old derailleur cause i had thought about that..

You can use a BB mount tensioner.

cooldad

Depends on the BB, and a tensioner is not a guide.

I know, i call it a tensioner because it winds Beginner up.

cooldad

Fair enough. Wind away.

Could you tell me or give links where i can get a bottom bracket that will have ISCG tabs for a chain guide..plz thanks

That's the frame, not the bb. If you don't have iscg tabs then you need to use and external bb as a mount.

cooldad

So back to this

single speed front and 8 at the rear...

But that is not fully answering question.

But presumably a cartridge, so you can't.
Unless it's on the seatube, like a mech.

I was asking what bottom bracket do i need to run a chain guide or could i run a chain guide on a Pinnacle Iroko 2 2012 Mountain Bike Frame........ not a beginner either just never really dealt with chain guides before have been biking 5 year and am a full qualified mountain bike instructor...

Chunkers1980

That may be the case but you seem not to be capable of answering questions!

You need iscg tabs on the frame or an external bb if none of those you are forced into using a seat tube mounted device much like a front mech.

iainstark

thanks.. did not know anything about chain guides so was hard to answer some of the questions.. sorry for the trouble
