Parts Formula Selva R Air Sprung Fork

The Selva range of forks from Formula is a culmination of 10 years of development and refinement from the Italian manufacturer of some of the world’s best Mountain Bike and Motor Bike components.

The Selva features hard-anodized 35mm 7075 Aluminium stanchions on a hollow forged aluminium crown with anodized aluminium 1 1/8″ to 1 1/2″ tapered steerer tubes. Matt Black powder-coated aluminium alloy lowers feature 15mm integrated quick-release axles and 110mm Boost spacing as standard. All Selva models feature 21 clicks of rebound damping and 12 clicks of both high and low-speed compression damping adjustment as we will as being CTS compatible.

Formula’s CTS Compression Tuning System gives you the power to change your compression damping characteristics in as little as five minutes. No more pulling your fork off your bike to send it off to a suspension specialist and paying them to have the damping modified, hoping that they’ll get it just the way you want it while you wait patiently for weeks to get it back. With the Formula Compression Tuning System, you can choose from 7 distinctly different compression damping circuits that you can swap yourself, with basic hand tools, at home, with the fork still on the bike!

The Selva range of forks from Formula also provides internally adjustable travel reduction (air springs only) and interchangeability between dual-air, single-air and coil spring types so you can easily adapt your fork to your needs as they progress. (kits sold separately)

The Selva R features a dual air-spring, meaning it has separate positive and negative air chambers for better customisation of sensitivity letting you precisely tune the forks response around your sag point.

The Selva R is an Enduro oriented fork with up to 160mm of travel in the standard version and 180mm in the ‘extended’ variant. (the 29″ extended has 170mm travel) Gold and Blue CTS compression valves are included and others are available separately. The Gold valve is the closest to the “industry-standard” set-up of a MTB fork: great sensitivity in the first two centimetres of travel, the right amount of support at low and medium speeds, and a constant though gentle progressivity. The Blue valve has been designed to combine comfort and support, providing a more pronounced progressivity, for that reason it makes the fork more suitable for those riding styles that look for comfort at lower speeds and support at the higher speeds.

The Selva R has the same damping as the other models of the Selva family: compression, CTS (Compression Tuning System) with interchangeable valves, rebound, lock-out, and lock-out threshold.

With the Selva R, Formula has combined a state of the art dual air spring with the tunability of the CTS system, which allows almost unlimited configurations of the compression curve.

Who’s this item for: Gravity oriented riders who want ultimate adjustability of their air fork.

Spring type: The Selva R is a dual air-sprung fork incorporating separate positive and negative air springs.

Wheel size compatibility: There are two models to suit 27.5″ and 29″/27.5″+.

Fork offset: 37mm on the 27.5″ fork and 43mm on the 29″ fork.

Axle to crown height:

• 27.5″ – 550mm @ 160mm and 570mm @ 180mm travel
• 29″ – 565mm @ 160mm and 575mm @ 170mm travel

Suspension travel amount: 27.5″ – Standard 160mm, Extended 180mm. 29″ – Standard 160mm, Extended 170mm.

Compression damper style technologies / adjustments: Drop-In Cartridge with Internal Floating Technology and Formula’s CTS interchangeable Compression Tune System valves. All Selva models feature 12 clicks of both high and low-speed compression damping adjustment as well as a lockout and lockout threshold adjustment.

Rebound damper technologies / adjustments: Drop-In Cartridge with Internal Floating Technology featuring 21 clicks of rebound damping.

Travel adjustability: The Selva R can be reduced to 140mm for the standard version and reduced by 10mm in the extended version with all parts required already included. There is an optional kit to reduce the standard version to 120-130mm.

Volume adjustability: The Selva R uses Formula’s Neopos air volume adjustment. If you think of the Neopos as an air volume spacer that can be compressed, the Neopos makes it possible to make the air forks progression curve more linear, thus avoiding the excessive progressivity given by the traditional volume spacers. With the Neopos you get all the support of a traditional volume spacer halfway through the travel, but without the abrupt ramp in the final part of the compression curve. The progression curve will always remain gradual, allowing you to use all the available travel of your fork. A more linear curve, using all the available travel. Sounds like a coil, right?

Pros: This has got to be the most user-adjustable air fork on the market. There is no setting you can’t reach yourself.

Cons: This could be the most user-adjustable air fork on the market!
