Suspension Fork Mounts

Weight is the key difference between the two different versions. The performance of both the Carbon and Stainless Steel SFM is comparable. The overall look of the two different materials is of course slightly different.

Currently, forks with a leg diameter lower than 38mm or larger than 45mm are not accommodated. Luckily, most modern suspension forks, barring long travel forks such as Fox’s 38 or RockShox’s Zeb fall between the recommended dimensions. Please note the SFMs are not compatible with the Fox 34 Step-Cast 2022/23+ Fork (earlier models are compatible), the Fox 34 Float Performance Elite Fork OR the Fox 32 Taper-Cast Gravel Fork

This is due to the raised section on the reverse of the fork legs.

Just as if you over-tighten your seatpost collar and find your dropper post performance hampered, exert too much clamping force on a thin-walled suspension fork, and performance can be compromised, potentially damaging the sensitive internals. Through exhaustive testing, we have created an accessory mount that requires minimal clamping force, thus minimising the risks to your expensive suspension fork.

The Tailfin SFM is unique in giving three different cage mounting points. If mounting a single cage, you may choose any of the three. When mounting two cages, you will need to use the two outside mounting positions. We suggest positioning the SFM at an angle that places cages as close to the fork as possible.

The Tailfin SFM is shipped as a pair. Giving you all you need to attach cages to ONE side of your suspension fork. Order TWO sets to fit cages to both sides of your fork.

The SFM has been designed to minimise the chance of scratching; however, with repeated fitting and removal, slight scratching could occur. We recommend applying a thin layer of helicopter/self-amalgamating protective tape if you want to protect your decals fully. Remember to measure your SFM after the tape has been applied.

In order to ensure the complete and unrestricted performance of your suspension fork, it is highly important not to exceed the recommended maximum torque of 3Nm. As with any precision component, the use of a torque wrench is required for safe fitting.

Carbon fibre and stainless steel were chosen as materials for making the SFM, as one of the key properties of both is the ability to resist an effect called ‘creep’. Creep is a behaviour observed in polymeric (plastic) materials in which they gradually deform over time when subjected to a constant strain, even if that strain is within the recommended limits. It occurs as a function of time through extended exposure to levels of stress that are below the yield strength of the material. Given sufficient time, this can lead to creep rupture, the failure within a material as a result of continuously applied stress at a level below the tensile strength. Plastic materials are particularly prone to creep rupture through exposure to static stresses. Simple answer: carbon and steel SFMs will last longer and perform better than plastic counterparts.

Yes, as long as the diameter is within the 38-45mm. Lefty Ocho – yes, but you will need to clamp below the cable guide.

No, currently the SFM does not fit a Rudy fork, as the lower leg tapers too much.
