The BSD CRBN-XLT Back Street Pro is a top end premium complete rear cassette wheel built for riders who want the very best in performance and durability. It combines the proven Back Street Pro cassette hub with the new ultra-light CRBN-XLT carbon fibre rim for an unparalleled fast and responsive ride.
Constructed from premium Toray T700 carbon fibre, the rim weighs just 340g (12oz), dramatically reducing rotational weight for faster spins, quicker hops, and a more responsive ride. Despite its incredibly low weight, features like ultra-thick sidewalls, reinforced spoke seats, and aligned cross-over lacing ensure exceptional strength and long-term durability.
Designed for riders who want the very best, this wheel delivers top-tier performance, premium materials, and the smooth, reliable feel BSD hubs are known for — making it a true high-end upgrade.
Rigorously tested for over five years by the BSD team - including Alex Donnachie, Kriss Kyle, Gaspar Guendulain, Andriy Podoba, and Guy Scroggie - the CRBN-XLT rim was developed to balance lightweight performance with heavy-duty strength.
