The dc-8 perch includes the legendary arc folding/adjustable lever.The lever uses an "external pivot" that has replaceable bushings in the perch.This means no up and down play in the lever.There is a nylon sleeve on the handlebar that helps the perch rotate in a crash preventing damage.The quick adjust is 1/3 turn and very easy to access.The perch part is made from die cast aluminum and cnc machined for accuracy.This perch has the same geometry, function and durability as our rc-8 perch without the cost it is available with an aluminum or composite lever.
