Suspension Fork Mount


The SFM is a universal clamp system that enables suspension fork users to mount cargo or water bottle cages to the lower leg of the fork.

The SFM ship as a pair, allowing you to fit one side of your fork.

The Carbon SFMs are currently out of stock. To receive an alert when they are available again, please click here.

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.

Just as if you overtighten your seatpost collar and find your dropper post performance hampered, exert too much clamping force to a thin walled suspension fork and performance can be compromised and potentially damage 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 an impact associated with products manufactured from polymeric materials (plastics) whereby any increased strain - even that under the recommended level. 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.

Tailfin Suspension Fork Mount

The mounts work beautifully and have been tested on 2 bikepacking trips with lots of singletrack with a fully loaded bike. The design allows each mount to carry 2 seperate loads on each fork. I carried an Apidura front fork pack using a Salsa Cage and behind this a water bottle cage (and bottle) on each fork. Rock Solid. I intend to leave the mounts on after I take off the cages as they are very discreet and actually look pretty sleek. Very happy with these.

Tailfin Suspension Fork Mount (SFM) and Small Cage

My wife and I just completed last week the northern half of the Oregon Timber Trail (north to south), which is extremely rough on sections (especially in recently opened areas nuked by past fires). We both used a SFMs (two on each fork leg) and a small TF cargo rack on each leg. 34mm Fox. Each leg had a King water bottle cage, which each carried a liter bottle. Each of my racks carried a 5-liter drybag. My drybags carried a sleeping bag (810g) and sleeping pad (650g), respectively. My wife's setup was the same except one of her drybags carried various things that weighed about a kg. The bottle cages were faced outwards and the drybags faced the rear. We used velcro straps to secure the bottles to the bottle cages even more. We used 20" Voile straps for the TF cages (two each) *Straps were a last minute local purchase because of drybag sizing unknowns, so I'm curious about TFs straps* Both the SFMs and the small cargo racks worked perfectly. Zero slipping or shifting. I retightened the bolts slightly after about week on trail. Tightened bolts to the directed torque. My only gripe are the torx bolts.... I absolutely hate torx (gonna swap them out). Other than that, perfect product.

Good quality

Have had occasion to use it on trips out to Colorado and Washington state and the rack and bags have performed as advertised. I can’t speak to their durability yet but they seem like they will last for years to come. I will likely buy from tailfin again.
