Fuji adds disc brakes and thru axles to the SL for 2017

Fuji's featherweight racer gets added stopping power

Following in the footsteps of the Gran Fondo endurance frame, Fuji has quietly launched its featherweight racer – the SL with disc brakes. Information at this point is somewhat thin, but Fuji's SL minisite is now populated with five previously unseen frames bearing discs.

Based on what we know so far, the SL Disc's geometry is identical to the rim brake version except for the chainstays which are now 410mm, meaning the snappy, playful characteristics we loved about the SL should carry over to the disc-clad version.

Also, like the rim brake SL, the SL Disc has Fuji's size specific 'optimal range of trail' where the fork offset and head angle are tweaked depending on the frame size – in an attempt to maintain a consistent trail figure (and to avoid toe overlap) in all but the XXS frame size and provide uniform steering characteristics throughout the range.

Like the standard SL the 1-series frames get Fuji's C-15 high modulus carbon frame and FC-440 carbon fork, while the 2-series frames see the C-10 carbon. As you can imagine, the extra hardware and stopping power come with added weight and the flagship SL 1.1 Disc is claimed to weigh 6.33kg. It’s not in the same feathery league as the rim brake SL 1.1 (4.96kg), but it’s still an impressive figure none the less.

The new SL Disc also gets front and rear 12mm thru axles

The new SL Disc also gets front and rear 12mm thru axles, though the rear dropout is convertible. Based on what we know from the Gran Fondo, which has the same dropout specification, by undoing a 5mm nut and bolt on the dropout you can remove the threaded thru axle section and run a standard 135mm quick release skewer. The new SL Disc also appears to abide by the flat mount brake standard.

It's worth noting that the photos and spec lists for each of the new SL Disc frames differ slightly, which may mean the images feature rendered components or the specs have not yet been finalised.

Pricing and availability haven’t been announced yet and we'll update this story as more information is released.
