I picked this up on Craigslist for steal last year and I've been slowly upgrading. It's my first trials bike, and I mainly ride street. Would like some help from other trials riders with what other updates I could make. 2004 (i think) Echo Pure (has rear disc mounts) BB7 brakes, avid speed dial levers - was thinking to update rear to Magura HS33 (frame has canti mounts) Rear Wheel - surly hub, not sure about the rim, bontrager earl tire Front Wheel - sucks, heavy MTN wheel, maxxis high roller tire- was thinking to replace this next Cranks - Echo with front freewheel Echo stem, bars - thinking about going with some wider bars Would really like some advice on what to upgrade next. Thanks in advance!
