Features

Takes 20x1-1/8 to 20x1-3/8. The 451x23mm ETRTO size covers the usual race tyres, so check your tyre falls in that range before building.
391mm ERD, 28 hole. Work your spoke lengths off an ERD of 391mm and a 28H drilling, so the build comes up right first time.
Toray T700 carbon fibre. High quality carbon keeps the rim light and stiff, in an understated unidirectional finish with tonal branding only.
4D drilled spoke holes. The holes are drilled to the spoke path, which takes stress off the nipple and spoke as the wheel comes up to tension.
38mm deep section. A deep carbon profile for a stiff wheel, backed by a 2 year warranty against manufacturer defects.
