Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Code:SPEEDCONCEPTSLR9AXSRD-RD

Speed Concept SLR 9 AXS is engineered to turn power into speed, combining an aerodynamic 800 Series OCLV Carbon frame with extensive integration for triathlon racing. KVF tube shaping, a full-foil carbon fork and integrated cockpit are designed around aerodynamic efficiency, while IsoSpeed helps smooth the ride when you're spending long hours in an aggressive race position.

A SRAM RED AXS E1 electronic drivetrain delivers wireless 2x12-speed shifting, paired with a 48/35T crankset featuring an integrated power meter and a 10–33T cassette. SRAM AXS Wireless Blips are positioned at the basebar and extensions, helping keep shifting controls accessible from different riding positions.

Bontrager Aeolus RSL 51 OCLV Carbon wheels complete the race-focused build, paired with Bontrager R4 320 700x25mm tyres. Integrated downtube storage, Bento box, bottle cage and dedicated Speed Concept bottle further reduce the need for externally added storage and hydration solutions.
