Trek Speed Concept SLR 7 AXS

The 2023 "Speed Concept SLR 7 AXS" model from Trek is a state-of-the-art triathlon and time trial bike that stands out for its advanced technology and high-quality components. The price for this model is 10,499 EUR.

The frame of the Speed Concept SLR 7 AXS is made from 800 Series OCLV Carbon and utilises the KVF (Kammtail Virtual Foil) tube profile to optimise aerodynamics. The frame is fitted with a T47 bottom bracket and features integrated solutions such as a Bento Box and a down tube storage compartment to enhance functionality. The bike’s maximum permissible weight is 136 kg, whilst the bike itself weighs 9 kg.

SRAM Force hydraulic disc brakes have been fitted to both the front and rear. The brakes are fitted with SRAM S-900 Aero brake levers and SRAM CenterLine X brake discs, which feature a Centre Lock mount and rounded edges. The brake discs have a diameter of 160 mm.

The gear system is controlled by the SRAM eTap AXS BlipBox shifter, supplemented by SRAM eTap Clics for stem mounting and SRAM eTap AXS Wireless Blips for handlebar mounting. The front derailleur is a solder-on version of the SRAM Force eTap AXS. The bike’s fork is an SC Full Foil Carbon fork with an integrated brake and stem system.

The crankset consists of the SRAM Force AXS Power Meter with a 48/35 gear ratio and a crank arm length of 172.5 mm. The bottom bracket is a threaded SRAM DUB, T47. The cassette is an SRAM Force XG-1270 with a 10–33 range and 12 speeds. The drivetrain is also from SRAM Force and offers 12 speeds.

The handlebars are Speed Concept Mid-Rise Bar/Stem, which ensure an aerodynamic riding position. The tyres are Bontrager R3 in size 700 x 25. The wheelset consists of Bontrager Aeolus Pro 51 wheels, which are made from OCLV carbon and are tubeless-ready. The front hub has a 100 x 12 mm thru-axle, whilst the rear hub has a 142 x 12 mm thru-axle with an SRAM XD-R freehub body.

The saddle is a Bontrager Hilo Comp with CrMo-tube rails, mounted on a Speed Concept SLR seatpost, which has an offset of either 11.5 mm or -20 mm. The bike’s packaging dimensions are 21 mm wide, 119 mm high and 189 mm long.

The frame geometry comprises a reach of 42 mm and a stack of 52 mm. The seat tube length is also 52 mm, as is the top tube length. The head tube angle is 72 degrees, whilst the seat tube angle is 78 degrees. The head tube length is 9 mm, the chainstay length is 41 mm and the standover height is 78 mm. The bike’s wheelbase measures 100 mm in total.

The Trek Speed Concept SLR 7 AXS is therefore a high-performance, aerodynamically optimised bike designed for ambitious triathletes and time trialists who prioritise speed and efficiency.
