Excellent quality frame constructed from 6061-U6 aluminium. The internal head tube (110mm long) has a large hole machined out to save extra weight.
Upper and lower gussets are welded to the frame to help join the top and down tubes to the head tube, providing extra durability and stiffness.
4-bolt brake mounts, spaced at 100mm, with built-in brake booster are machined from a single piece of aluminium, improving brake stiffness and increasing frame strength.
Machined Bottom Bracket yoke stiffens up the rear end of the frame and improves tyre and freewheel clearance. This allows you to run a wider tyre (2.4/2.5).
135mm dropouts featuring Onza's unique integrated tensioner system, removing the need for snail cams or frame hanger.
