The revolutionary Twinwall® handlebar is an oversized diameter 1 1/8″ (28.6mm) handlebar which utilises two tubes, one within the other, borrowing principles from aircraft design to give the best combination of lightness, strength and safety.
Since their introduction in 1998, the Twinwall has been the handlebar of choice for more professional race teams and has helped more riders win championships than any other handlebar in the world.
The following features are integral to the Renthal Twinwall® handlebars.
- Twinwall construction – Consists of two aluminium alloy tubes one within the other
- Outer tube is 7010 T73, which has extreme resistance to mechanical damage and is anodised to prevent corrosion
- Inner tube is ultra high strength 7010 T6 Aluminium and is hard anodised to resist wear from twist grip and controls
- Rubber seals cover the join to keep out water and cleaning fluids
- Laser etched positioning grid
- Renthal? s pioneered bonded lightweight single bolt clamping system for the crossbrace, greatly increases strength whilst still allowing flex
- Knurling – Grip end only – increases bonding between bar and grip
- No knurling in clamp area, this could cause a stress riser and lead to fatigue failure
- A specially developed injection moulded crossbar pad is fitted with every handlebar
