How it compares

With 200 mm at the fork, the Propain Spindrift AL Dual Crown sits above average: across the 12 bikes in the “freeride bike” category in our database, the median is 180 mm. The rear offers 180 mm, 20 mm less than the front. Among Propain’s mountain bikes, the Propain Spindrift AL Dual Crown is the model with the most fork travel. Propain builds the frame from aluminium.

The starting price of €3,399 (Base) is roughly in line with the category median (€3,270). The top build, Ultimate, costs €6,144. For suspension, Propain combines components from FOX, RockShox and Öhlins. The fork line-up ranges from the RockShox Boxxer Select to the RockShox Boxxer Ultimate Electric Red. With the Vivid Coil Select, the Base build has a coil shock – here the spring rate determines SAG.

Setup notes for this spec

Air fork (RockShox Boxxer Select): 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.
Coil spring (Vivid Coil Select): 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.
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.

Target SAG for the Propain Spindrift AL Dual Crown

Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion and on the shock shaft. Change the pressure step by step until you reach the value; if Propain gives its own target SAG, use that.

200 mm fork (all builds)

Riding style	Fork SAG
XC / touring	17 % = 34 mm
Trail	20 % = 40 mm
Enduro / rough	22 % = 44 mm
Bike park	20 % = 40 mm

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

Tyre pressure starting values

The values apply to 2.40″ wide tubeless tyres with a trail casing. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi).

Ready-to-ride weight	Front	Rear
60 kg	1.43 bar (21 psi)	1.63 bar (24 psi)
70 kg	1.55 bar (22 psi)	1.75 bar (25 psi)
80 kg	1.67 bar (24 psi)	1.87 bar (27 psi)
90 kg	1.79 bar (26 psi)	1.99 bar (29 psi)
100 kg	1.91 bar (28 psi)	2.11 bar (31 psi)
110 kg	2.03 bar (29 psi)	2.23 bar (32 psi)
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.

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