USE Atom Carbon riser bar review
The Atom risers are available in both oversize 31.8mm and standard 25.4mm diameters. This is a result of a seamless transition between round tube to diamond cross-section in the rise area.
With a comfortable 10 degrees of backsweep and a 1in (25mm) rise, the straight sections offer plenty of space for bar-mounted gadgetry and the stem clamp area has a non-slip coating.
These 660mm wide bars have alloy reinforcement internally under the brake clamps and at the ends to prevent crash damage. Instant comfort and a matt ﬁnish make them a great product from a UK company with a pedigree in carbon.
