I would eventually like to convert my bike to an IGH but I don't want to use a chain tensioner. The bike has vertical dropouts so to keep that "clean" look I would need an eccentric bottom bracket. So far the only EBBs that I've found for a standard size BB shell are these offers from Tr!ckstuff, Forward Components, and Yess Labs. Does anyone here have any experience with these products? Pros and cons regarding the ordering, installation, price, and performance would be well appreciated.

Alternatively, Yess Labs offers this chain tensioner which is unlike one I've ever seen:



It makes a much cleaner look than one that hangs in the traditional derailleur position. Has anyone here had experience with this product? It's cheaper than the EBBs but it precludes the use of the Hebie Chainglider that I would like to use for my application:



Thanks for the input.

can you select the right chainring and cog tooth-counts to get the right tension in 1-link increments?

I've considered that but I would be concerned about the chain stretch - or more correctly, erosion. That being said, however, I have no idea how long it would take for that "stretch" to become noticeable. Also, how would I remove the rear wheel with that kind of setup? Would I have to remove the chain to do that? If that's the case I guess I would need one of those special links that enables quick removal (and I mean guess - I've never taken a chain apart before.)

Anyone? Should I be posting this question on a different forum than Commuting?

You might want to ask these guys. They are very knowledgeable and friendly.

Mr IGH

Is the Yess Labs adapter for BMX bottom brackets (for 1 piece cranks)?The Forward Components owner hangs out on the MTBR.com SS forum, it seems to be good if you go by the posts there.

Thanks. I'll check those out.
