How it compares

170 mm at the fork almost exactly matches the 170 mm median of the 56 bikes in the “e-enduro bike” category in our database. Front and rear both work with 170 mm of travel. No other Santa Cruz model among its e-mountain bikes has more travel up front. Santa Cruz builds the frame from carbon.

The lightest build, X0 AXS RSV 2027, weighs 21.7 kg according to Santa Cruz – about 1.7 kg less than the category median (23.5 kg across 19 bikes with a stated weight). Within the range, weight varies by 1.0 kg. At €7,699 for the 70 2026 build, pricing is typical for the category (median €6,900). For the XT Di2 RSV 2027 build, Santa Cruz asks €11,999. For suspension, Santa Cruz combines components from FOX and RockShox. The fork line-up ranges from the RockShox Zeb Base, 170mm to the Fox Podium Factory, Grip X2, 170mm. The XT Di2 RSV 2027 build uses a coil shock (Fox DHX2 Factory), so SAG is set with the spring rate rather than air pressure. It is powered by Bosch Performance CX BDU38 with a 600 Wh battery.

Setup notes for this spec

Fork (RockShox Zeb Base, 170mm): air goes in through the valve on top of the left leg. After every change, compress the fork firmly a few times before measuring SAG.
Rebound: turn the red FOX and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
Coil spring (Fox DHX2 Factory): if SAG is off, only a different spring rate will fix it. Preload should just keep the spring from rattling; more preload makes the shock less supple.
Shock (FOX Float X Performance): get on the bike in your normal riding position, step off carefully and read the O-ring. Always cycle the shock a few times after pumping.
e-MTB: because of the extra weight, start with slightly more tyre pressure – the surcharge is already built into the table below.

Target SAG for the Santa Cruz Bullit

The table converts the recommended SAG percentages into millimetres, so you can check them with the O-ring directly on the stanchion and on the shock shaft. Adjust the air pressure until the value is right. If Santa Cruz specifies its own target SAG for your model, that takes priority.

170 mm fork, 65.0 mm shock stroke (all builds)

Riding style	Fork SAG	Shock SAG
XC / touring	17 % = 29 mm	24 % = 15.6 mm on the shock shaft
Trail	20 % = 34 mm	28 % = 18.2 mm on the shock shaft
Enduro / rough	22 % = 37 mm	30 % = 19.5 mm on the shock shaft
Bike park	20 % = 34 mm	27 % = 17.6 mm on the shock shaft

How to measure SAG is explained in our guide SAG setup.

Tyre pressure starting values

The values apply to 2.50″ wide tubeless tyres with a trail casing, including the e-MTB surcharge. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi). Stock tyres: Maxxis Assegai 29"x2.5", 3C MaxxGrip, Double Down / Maxxis Minion DHRII 27.5"x2.5", 3C MaxxTerra, DoubleDown; Maxxis Assegai 29"x2.5", 3C, MaxxGrip, Double Down / Maxxis Minion DHRII 27.5"x2.5", 3C MaxxTerra, DoubleDown.

Ready-to-ride weight	Front	Rear
60 kg	1.48 bar (21 psi)	1.68 bar (24 psi)
70 kg	1.60 bar (23 psi)	1.80 bar (26 psi)
80 kg	1.72 bar (25 psi)	1.92 bar (28 psi)
90 kg	1.84 bar (27 psi)	2.04 bar (30 psi)
100 kg	1.96 bar (28 psi)	2.16 bar (31 psi)
110 kg	2.08 bar (30 psi)	2.28 bar (33 psi)
120 kg	2.20 bar (32 psi)	2.40 bar (35 psi)

Air pressure in the fork and shock

You will find a guide value for air pressure on the fork sticker (or on the shock) or in the suspension makers’ charts. Our calculator also takes riding style and rebound into account. In the end, measured SAG is what counts.

Note: all information without guarantee. Specs can differ by model year, frame size and market – the type plate, the owner’s manual and Santa Cruz’s information are authoritative. Never exceed the maximum pressures of fork, shock, tyres and rims.
