How it compares
120 mm at the fork almost exactly matches the 120 mm median of the 23 bikes in the “cross-country full-suspension bike” category in our database. Travel is the same front and rear at 120 mm each. Within Lapierre’s mountain bikes, it sits between the Lapierre Prorace and the Lapierre Zesty TR on travel. The frame is made of carbon.
The starting price of €3,799 (5.9) is roughly in line with the category median (€4,350). The top build, 10.9, costs €10,000. For suspension, Lapierre combines components from FOX and RockShox. In total, 4 different forks are used, from the RockShox SID Select 3P to the RockShox SID Ultimate 3P Race Day Remote. Lapierre gives a maximum system weight of 120 kg for bike, rider and luggage combined.
Setup notes for this spec
- Fork (RockShox SID Select 3P): 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: 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.
- Shock (RockShox SID Luxe Select+ 3P): 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.
Target SAG for the Lapierre XR
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 Lapierre take priority.
120 mm fork, 50.0 mm shock stroke (all builds)
| Riding style | Fork SAG | Shock SAG |
|---|---|---|
| XC / touring | 17 % = 20 mm | 24 % = 12.0 mm on the shock shaft |
| Trail | 20 % = 24 mm | 28 % = 14.0 mm on the shock shaft |
| Enduro / rough | 22 % = 26 mm | 30 % = 15.0 mm on the shock shaft |
| Bike park | 20 % = 24 mm | 27 % = 13.5 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. 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 Trinotal Race Grip 60-622; Continental Trinotal Trail Grip 60-622; Michelin JET XC3 RL FB TLR 60-622.
| Ready-to-ride weight | Front | Rear |

| 120 kg | 2.15 bar (31 psi) | 2.35 bar (34 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.
