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. Unusually, the rear end offers 172 mm – 2 mm more travel than the fork. Among CUBE’s e-mountain bikes, the CUBE Stereo Hybrid ONE77 HPC is the model with the most fork travel. Depending on the build, the frame is carbon or aluminium.

23.5 kg for the SLT 800 build puts the CUBE Stereo Hybrid ONE77 HPC mid-pack on weight (median: 23.5 kg). There are 1.6 kg between the lightest and the heaviest build. Depending on the build, fork and shock come from FOX and RockShox. In total, 4 different forks are used, from the FOX 38 Float Factory GRIP X2 to the RockShox ZEB Select+ Charger 3.2 RC2 Air. It is powered by Bosch Performance Line CX or Bosch Performance Line CX-R with a 800 Wh battery.

Setup notes for this spec

Air fork (FOX 38 Float Factory GRIP X2): the air valve is on top of the left leg under a cap. Change pressure in small steps (about 5 psi (0.34 bar)) and cycle the fork a few times afterwards so the air chambers can equalise.
Rebound: on FOX and RockShox suspension the rebound adjuster is red. Always count clicks from fully closed (clockwise to the stop) so you can return to any setting.
Air shock (FOX Float X2 Factory): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
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 CUBE Stereo Hybrid ONE77 HPC

SAG is the share of travel your weight already uses in the riding position. The table gives it straight in millimetres – read the O-ring on the stanchion and on the shock shaft and adjust the air pressure until it matches. Any figures from CUBE take 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

For 2.40″ wide tyres, tubeless with a trail casing, including the e-MTB surcharge. With an inner tube about 0.2 bar (2.9 psi) more, with an insert about 0.1 bar (1.5 psi) less. Stock tyres: Continental Argotal / Kryptotal Rear 2.4; Schwalbe Magic Mary / Tacky Chan 2.4; Schwalbe Magic Mary Trail Pro / Albert Gravity Pro 2.5.

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: no guarantee is given. Specs can vary by model year, size and country; the type plate, the manual and CUBE are authoritative. The maximum pressures of fork, shock, tyres and rims always apply.
