Thomson - Carbon Road Drop Bar 31.8 x

Carbon fibre road racing handlebar features a mild wing shape on top, clamping area wide enough for aero bars and mid-compact reach and drop. This is the modern road racing handlebar for the modern road bike. The wing section is small enough not to restrict hand movements when riding on the top and allows bar angle adjustment without locking out your wrists. Shaping on the bottom side of the wing allows housing to be taped out of the way without the use of narrow housing channels or internal routing, both of which shorten bar life. Certified to EN, tested to DIN+.

The layup uses 3 different fibre types with different tensile strengths and tensile modulus, including High Strength carbon fibre. This helps allocate stiffness and flex where needed.

All carbon fibre is produced by Toray and uses tailor-made Nano Epoxy Resin for very high impact resistance. Toray is the main supplier of carbon fibre for Boeing and Airbus.

The Road bars are made in one piece, not three pieces co-moulded and glued together. The bars are moulded over an EPS mandrel to avoid wrinkles inside the layup during moulding. Most other bars are moulded over inflatable nylon bladders.

Reach for the Road bars is 78.5mm. Drop is proportional.
The road drops are:

40cm - 137mm.
42cm - 140mm.
44cm - 140mm.
46cm - 143mm.

1.5K woven impact ends help prevent damage to unidirectional fibres from impact.
