Description

Kona's Lava Dome offers a lot of performance for the money. This bike is perfect for someone who wants to try out trail riding but doesn't have a big budget. The Lava Dome features a lightweight, tough aluminum frame and a Suntour fork to soften the bumps. SRAM components make up the drivetrain, and parts from Alex, Vittoria, Wellgo, and Kona round out the spec. Tektro's powerful hydraulic discs take care of braking.

Features

ST3

When we first started building bikes it quickly became
apparent that traditional frame geometry wasn't going to cut it on the
steep descents and tight turning singletrack of southern British
Columbia. To help tame this rugged landscape we developed ST3 Geometry -
or Sloping Top Tube Technology. A sloping top tube means increased
frame stiffness and strength, and when things aren't going so well, more
stand over height for crucial dismounting ease.


The frame layout creates a compact front end, giving increased agility
in tight turning singletrack while providing increased stiffness for
greater control in all conditions. It's also bomber construction: with a
greater separation between the top tube/seat tube and seat tube/seat
stay welds, frame stress is distributed over a larger area of the seat
tube. Originated by Rocky Mountain and copied by others, ST3 delivers a
better handling, stronger frame - the ride of a lifetime.
