    Yah you can select any gear but it still starts out in 1st and wont exceed the gear you select witch sucks somes especialy if you want to start in second for low traction areas.

    That's OK. My worry was that the PRNDL didn't have 2nd available at all. A lot of times it's the perfect gear for cruising down a trail at lower speeds. My other concern was not being able to manually select 4th when climbing a grade, but the ODLO mod fixes that.
