Renthal’s Duo Stem uses a unique, horizontally split two-piece design to achieve high strength with low weight.
At 143.5g (claimed, with bolts), it’s not earth shatteringly light, but given that it’s made for gravity riding and jumping, that’s pretty good. The design allows them full access to the insides, letting them machine away more unnecessary material without compromising strength. it’s CNC’d from 6082 billet aluminum. Renthal says the bottom, U-shaped section cradles the bar for excellent support. MSRP is $99.95. Specs: 50mm length, 10º rise, 1-1/8″ steerer clamp, OS31.8 handlebar clamp.
