ABS FORK

Abs Fork Tune is an Italian product created to help your mountain bike fork fine-tuning and function optimisation according to the rider’s needs and rider’s technical ability , this kit as well as allowing to modify the compression curve and the damping speed (compression and extension) linearises the elastic operation of the fork according to overheating from prolonged use during a long off-road descent avoiding hardening, eliminates vibrations though the hands, keeps the air chamber lubricated by means of its specific grease reducing the clutches and thus increasing the sensitivity of handling, making it a “plush” fork in all senses.

HOW DOES ABS FORK WORK?

Abs Fork Tune is an Italian product created to help your mountain bike fork fine-tuning and function optimisation according to the rider’s needs and rider’s technical ability , this kit as well as allowing to modify the compression curve and the damping speed (compression and extension) linearises the elastic operation of the fork according to overheating from prolonged use during a long off-road descent avoiding hardening, eliminates vibrations though the hands, keeps the air chamber lubricated by means of its specific grease reducing the clutches and thus increasing the sensitivity of handling, making it a “plush” fork in all senses.

AbsFork is available in 2 versions (modular systems) to meet the needs of any Rider:

Kit comfort & Grip:
In the RACE field it’s necessary to have a S.A.G. of 15% to exult the characteristics of the product, on the contrary for a normal use (for example touring on Ebike) we recommend a S.A.G. 25-30%. Further decreasing the number of cylinders will gradually produce a more sustained and linear fork at the expense of comfort.
Kit Race:
Use this kit where high performance is necessary at the expense of comfort, we recommend an abundant 20-25% S.A.G. to make the fork very strong at low speeds.By further decreasing the number of cylinders, a more sustained and linear fork will gradually be obtained at the expense of comfort.

* Both kits are supplied with different modular cylinders by means of a rod and their specific lubrication grease (10 cylinders + 1 rod for 34 to 36mm forks with 140-180mm travel) (7 cylinders + 1 shaft for the forks from 32-33mm with excursion 80-110mm)

AbsForkTune can be installed on all air mountain bike forks with stem diameters from 32 to 36mm, including forks with rod (old models Fox or RS dual position) where in this case the rod supplied in the kit must not be used in this case the cylinders will be inserted directly on the rod.

Preliminary operations and necessary material:

1) With a high pressure pump for suspension forks, acquire a suitable cup wrench to unscrew the air fork chamber cap. Before carrying out any operation, it is necessary to carefully clean the area where it will be inserted to prevent impurities from ending up inside the fork chamber during the kit installation.

2) Before installing AbsFork, write down the inflation pressure reading from the pump pressure gauge.

3) Using the high pressure pump, inflate the air chamber. It is very important to make sure that the chamber is completely deflated to avoid unintentional plug removal operations.

4) Unscrew using your Cup wrench (not supplied in the kit), the air chamber cap to access the compartment where the ABS FORK TUNE will go. Before installing the product remove any (token) “volume spacer” present in the positive chamber.

5) Depending on the fork model, create your ABS FORK TUNE kit on the supplied rod (7 or 10 cylinders according to the excursion or your riding needs) and lubricate with the grease (PM600 military type or transparent silicone grease) starting from the bottom (contact area with the plunger in the positive chamber ) working upwards.

6) Insert the suitably greased kit into the fork chamber.

7) Exerting pressure between the bow with one hand and on the cross with the other hand fully extend the fork throughout its travel.

8) Remove the unnecessary Abs Fork cylinders so that there is at least 15mm offset between the base of the cap and the installed Kit.

9) Fully extend the fork again.

10) Measure the offset with meter or caliper in such a way that once screwed the positive chamber plug have 15mm between it and the installed KIT.

11) Screw the cap back on by hand.

12) Tighten the plug with the torque indicated by the manufacturer of the suspension.

13) Inflate the positive fork chamber with high pressure pump to obtain the S.A.G. desired.
