Checklist for Gates Beltdrive conversion... Having had a good look at a Scott Sub 10 1012 model today I'm very very VERY keen to convert my On-One Pompetamine Versa 8 to belt-drive. It has a Shimano Alfin 8 hub.

So... what advice can you give me? So far I know/think that:


I need to get the read-triangle on the drive side cut and have a gate brazed in (I'll do this myself probably).
I'll need to get hold of an Alfin fit sprocket.
I don't have an eccentric BB mount/shell so will have to tension with track-ends and tugs (or will I??)
That it's blinking expensive :)


Thanks!
The biggest hurdle is definitely engineering the split dropout or the separable chainstay. S and S Machine doesn't sell their S&amp;S couplers to amateurs, so the most elegant method of splitting the chainstay proper isn't really available to you.  Other methods - using flat stock or other threadings - are likely to provide endless headaches there. Gates publishes a spreadsheet containing engineering documents for a few different dropout designs, you could possibly make them or get them manufactured to your specification by a local machinist and braze them ion, but once again you're looking at some significant expense and complexity.  There are a few other dropout designs as well, but they appear to be proprietary.

Ultimately you're looking at a sub-$300 frameset; you might be best off finding a Gates-compatible mass-produced frameset and moving all your parts over to that.
