Mountain bike 21sp - Malvern Star.
Mountain bike 21sp - Malvern Star. Hi all, I'm selling a Malvern Star (51cm) mens 21spd mountain bike. This bike is definitely worth a look as it has lots of life left & features a quality Shimano drive train. Gears changes are made by pushing trigger buttons on the handlebar. You can shift down 3 gears at one time if needed. All 21spds are present although 2 to 3 of the gears hesitate & need to be pressed twice, but all 21 gears are there. I love vintage stuff but I'm hooked on bikes with
