Here is a summary of the main Ritchey MTB bars. Firstly the Ritchey Pro Carbon Rizer has a textured centre section for maximum clamp grip witha 20mm rise, 670mm width, 6 degree bend and 9 degree sweep back. The outer flat has an increased width section for accessory mounting and the weight is 220g.
Secondly, the Ritchey WCS Carbon Flat Handlebar uses leading aerospace grade materials with a textured stem clamp area to give extra torsional strength and vibration damping. This bar is designed for cross country use and weighs 135g at a width of 580mm with 5 degree bend.
The WCS Carbon Low Riser bar also has a textured stem clamp area to reduce slippage and the carbon wrap is tuned to provide torsional strength and vibration damping. Internally the bar is reinforced to accept bar ends and shifter/lever clamp. This is also for cross country use and weighs 175g.
Next is the Ritchey WCS Carbon Rizer Handlebar, which is also made in aerospace grade materials with a textured stem clamp area increasing torsional strength and giving good vibration damping during cross country use. Weight is 160g with a 9 degree bend, 32mm rise and 3 degree sweep.
