About this product
This is a carbon road drop bar with a 31.8 mm clamp diameter, available in 380, 400, 420 and 440 mm widths and finished in UD matte with external cable routing. Width is the decision that matters most: as a starting point, riders usually match the bar to shoulder width, measured across the bony points of the shoulders, and go wider for stability on rough roads or narrower for a tucked position. A 31.8 mm bar only fits a 31.8 mm stem, so check your stem before ordering, and note that this is a carbon component: it needs a torque wrench and the torque figure marked on the part, not a guess by feel. External routing keeps the cables visible and easy to service, at the cost of a slightly less clean front end.

Pros & cons
Pros
- Four widths from 380 to 440 mm, so you can pick by shoulder measurement instead of adapting
- 31.8 mm clamp is the current road standard, easy to match to an existing stem
- External routing keeps cable replacement simple and visible
- UD matte carbon finish suits most frame colours
Cons
- Carbon needs a torque wrench and the marked figure; over-tightening can crack the clamp area
- Only fits a 31.8 mm stem, older 25.4 mm or 26.0 mm setups will not work
- External routing leaves cables exposed to grit and looks busier
- Bar weight and drop/reach figures are not given in the listing
