Endurance race geometry, slightly more relaxed than pure race
Rim brake and disc options
Truncated aerofoil section tubes
New fork design and dropped seatstays for improved comfort
Hidden mudguard mounts (disc version)
Two women’s specific models
Clearance for 28mm tyres on rim brake models, 30mm on disc brake models
Aero, comfort and… mudguards
The new Boardmans were developed with UK riding in mindBoardman
The new SLR frames follow a template that’s become very familiar, and that’s no bad thing. Round tubes have been replaced by aerodynamically-slippery truncated aerofoil sections, saving a claimed 10W over the old SLR at 40km/h.
The seatstays have been dropped for more squish at the back, while the chainstays are big and boxy for stiffness. So far, so predictable.
Boardman pitches its geometry as being slightly less aggressive than that of a traditional race bike, with a touch less reach and 15 to 20mm more stack.
We’re pleased to see that rim brake versions get direct mount calipersBoardman
Perhaps more interestingly the new bikes are designed with bigger tyres in mind. Rim brake models are specced with 25s but their direct mount calipers will happily accept 28mm tyres. The disc bikes ship with 28s but have room for 30s.
Better yet, the disc frames have hidden mudguard mounts. Hallelujah!
If you’d rather hear it from the horse’s mouth, here’s Mr Boardman himself talking through the new platform
9 series SLR range overview — mostly Shimano, with a dash of SRAM eTap
While the SLR 8.9 Carbon has already effectively replaced the seemingly evergreen Team Carbon as the £1,000 option, the 9 series range currently starts at just £249 more with the SLR 9.0 (£500 more full retail price). The 9.0 is built with Boardman’s C8 grade carbon, Shimano 105 kit and Vision Team Comp 30 wheels.
(I’ve asked Boardman to shed light on its grades of carbon and will update this piece if/when that’s forthcoming.)
For £1,499 (£1,800 full retail) you can have an SLR 9.0 Disc instead, which gets 105 hydraulics. It’s notable that both 9.0s have previous generation 105 5800 components rather than the latest R7000 stuff, but they’re still well-specced machines.
