General questions
All-new frame with a high pivot suspension design
– Updated, slacker geometry and optional angle adjust headset cups
– Increased rear travel from 160 mm to 170 mm
– Leverage rate adjust chip
– Stock mixed-wheel builds (29” front, 27.5” rear) on all sizes except S (27.5” front and rear)
– Updated frame protection with Integrated Carbon Armour and a noise-reducing chain stay guard
– Room for longer dropper posts
Size S does.
No, there’s not enough fork or frame clearance.
Yes, size M and up can run a 29” rear wheel. This requires swapping the bolt-on lower shock mount (sold separately) and removing the integrated rear mudguard (not enough clearance for 29” wheel). See service manual for part numbers.
We don’t recommend it.
Because the angle-adjust headset and bolt-on lower shock mount make it redundant. Use the headset to adjust headtube angle, and the bolt-on lower shock mount to adjust BB height when switching rear wheel size.
Yes. The size-specific chain stay lengths are achieved by altering the position of the bottom bracket shell on the main frame. This means that replacement chain stays are the same for all frame sizes. See the geometry chart on the bike page for complete geo details
Yes, there is one for carbon, and one for alloy.
They will fit, but we did not test these configurations, so we cannot officially recommend it.
You can swap out your headset cups to get a full degree of head angle adjustment. The bikes come with neutral/zero-degree cups. Consult the service manual to find part numbers to order the angle-adjust headset cups.
The upper cup is a drop-in part, but the lower cup needs to be pressed in with a standard shop headset press. The cups have notches and laser-engraved guides to help you install them straight. For more detailed installation instructions, watch the Slash Service Tips video on Trek U.
2.5” max width for both 27.5” and 29” wheels.
All Slash complete bikes come with all the parts you need to set the wheels up tubeless. No additional parts required. Just add the included sealant.
Yes, they are larger than most idler pulleys for added efficiency. See the service manual for replacement part numbers.
Yes! Consult the Slash service manual for part numbers.
Carbon and Alloy – 190 mm max travel (all sizes), 587 mm axle-to-crown (size S), 606 mm axle-to-crown (size M-XL)
They will fit, but we haven’t tested them, so we cannot recommend a dual crown fork on Slash at this time. However, you can put a 190 mm single-crown fork on there, and that’s pretty close and has a better turning radius.
S – 290 mm, M – 305 mm, ML – 325 mm, L – 340 mm, XL – 370 mm
We know that the following shocks will fit. Other shocks may fit but should be checked for frame clearance at full suspension compression.
– RockShox Super Deluxe coil
– RockShox Super Deluxe AXS
– RockShox Vivid Air
– Fox Live Valve NEO
– Fox X2
Slash takes a 230 mm x 65 mm shock with an industry standard 54 mm x 10 mm upper and 20 mm x 8 mm lower standard pin mount.
Min – 28T, Max – 34T round, 32T oval
55 mm
Sizes S to L use a standard un-cut 126-link chain. Due to the longer chain stay length on the XL, that size requires 128 links.
BSA 73 mm, threaded
No Knock Block here.
Frame – 200 mm direct post mount with 220 mm max. Fork – check manufacturer spec
ISCG 05, 3-bolt
Some colourways will have paint-matched storage doors, but not all. Generally, matte paint jobs will not have paint-matched storage doors.
All models (even the frame sets!) come with a Bontrager right-side-load water bottle cage. Our apologies to the lefties.
There’s a new tool to make it easier to remove bearings in the rocker and main pivot. See service manual for part numbers
