another option you have is running bottom bracket convertor, but I dunno which cranks you're. but if reduce you can runn any chain guide you wish...
There isnt too many options for bmx (bottom bracket) chain guides, since most people run it single speed...

ok, since you have profiles, what you need is a euro-bottom bracket with the convertor and you can run any chain guide system you want. The convertor is about 20-25 dollars or you can get a used one for cheap somewhere.

damn, just when i thought i was making progress, shot down by E-13.  look at the email reply
looks like i have to wait till 2005 to get the guide i want

[/QUOTE]Tim,
Thanks for getting in touch. Unfortunately, even with the BB reducer our guides won't work in the BMX shell application. The new ISCG tab standard that we are working on for 2005 will allow ISCG tabs to be applied directly to BMX BB shells.
Sorry, Tim.

You know what try this, call Gerald at Racer's Edge, 718-531-3100. And see what he can do for you.
IMO, I dont see why it wouldn't work, you dont need the tabs to mount their guide, and not all frames with bmx bb has those tabs...

All it takes is a goode mechanic like Gerald who doesn't only know what he is doing, but UNDERSTANDS it as well.  I understand the dilemma with the ISCG adapter - I wonder how he is going to overcome it. tap his own holes in the BB adapter? Use a 118mm BB and space it out so the depth of the ISCG adapter doesnt bump into the BB adapter.

Hmm.. I will probably be a Seattleite by the time it is all done - post pictures so I can see the solution - intriguing!
