The bit behind the BB in your pic - I guess thats the "gears". Is it all easy enough to assemble then?
Looks easy enough to put together, the only faff is the facing of the BB/ISCG area, needs a specific SRAM tool to do (and only a few bike workshops in the UK have one, none in London!
) The bit behind the BB (in the pic) isn't the 'gear' component, the planetary gears are integrated with the crank arm & bashguard.
My only concern about HS is how long do those BBs last and how much do they cost to replace.
The BB is based on the Truvativ Howitzer, hopefully it turns out to be reasonably long lasting... a new one is around £45 to replace, not too bad...
