I wonder how the girl who posted her commuter in the 2nd link I left managed to fit some on then? I know from reading the thread that she had an adjustable (I think it was up to 45degree rise) stem, so maybe that stem also accepted both MTB and BMX bars if the receptacle part of the stem (where the handlebars slot in) was adjustable too?

Fuji86, thanks for the info, I'm sure it will help those looking for alloy bars, however I am hoping to get cro-mo handlebars which is one of the things which got me looking at BMX bars since that seems to be the main type of steering where you can find a lot of people offering cro-mo versions. So far, I haven't found a decent set of high rise cro-mo handlebars in the UK, but I'll keep looking in case I can't fit a suitable stem in my hybrid.

Anyway, I'll check with my LBS when I pick up my bike next week, however they tend to not be very helpful when it comes to 'unconventional' mods to bikes.

My bike is a Marin Muirwoods 29er with a cro-mo frame if that helps with any forthcoming advice, cheers.

Edit: Just found this post which advises using shims to allow bmx bars to fit in a 31.8mm stem:

Now if only I could find a good quality cro-mo stem somewhere...

Edit2: Just realised that fitting the 22.2mm BMX bars might be problematic in terms of refitting my 31.8mm gear shifters and brake leavers. They might be adaptable enough for the slightly larger 25.4mm bmx bars some places sell but 22.2mm might be pushing it?

I think I'll just need to keep looking for some suitable cromo MTB bars which sweep back 12 degrees and are narrower. The ones on the muirwoods 29er are far too wide, esp when squeezing between the curb and the cars when traffic is at a stand still.
