Lauf TR Boost Fork

Fast. Light. Stiff. The Lauf TR Boost is a unique match with today’s lightweight XC mountain bike frames. Nimble, light and ready for adventure.

  • Zero Maintenance
    The design of the Lauf TR Boost is based around eliminating all “moving parts”, and therefore, friction and maintenance. The monocoque carbon fiber structure delivers incredible strength, and the test-fork we have in our lab has already been “shocked” over 170 thousand times, without showing any signs of wear and tear. That equals more mountain-biking than you’ll manage to cram into at least 5 years of action!
  • S2 Springs
    The springs on the Lauf forks are made of military spec S2 glassfiber that is extremely tough on hits and flexible in the direction of the travel. The springs have been “shocked” in our test lab over 400.000 times reaching 40mm amplitude every time.
  • Progressive Spring Rate
    The Lauf TR Boost has 60mm of travel with progressive spring rate. This means that the further the fork compresses the springs become stiffer. This helps keeping the fork from bottoming without sacrificing small bump compliance.
  • Plus Tire Compatibility
    The TR Boost can take 27.5+ tires up to 3.0" as well as 29+ tires up to 2.8” wide. Some 29x3” tires will also fit but as tires are different from brand to brand you need to measure the tire beforehand.
  • Cargo Mounts
    We do not have cargo mounts on our forks but there are 3rd party solutions that can be used. For instance the Twofish Unlimited Quick Cage adapters that can be used with a broad variety of cages.


  • Wheels 29" / 29+ / 27.5+
    The TR Boost takes both 29” wheels and 27.5+ wheels as they share the same diameter, roughly.
  • Max Tire Width 29x3.0" / 27.5x3.0"
    Put a 27.5+ 3” tire under for more grip and playfulness or go for slightly larger 29” tires (in diameter) for a more racy setup. It’s always good practice to double check the fit beforehand. Some 29x3.0" tires but as tires vary from brand to brand make sure to test the fit.
  • Travel 60mm 
    This is the sweet spot for our forks. Since the travel is fairly short and progressive, we don’t need damping. That makes the fork a lot simpler and maintenance free.
  • Weight 1.000 g 
    The TR Boost is very light - especially when compared to other boost forks. Be prepared to lift your front wheel over rocks instead of navigating past. The TR Boost is 1.000g.
  • Unsprung Weight 260 g
    The low unsprung weight is one of the design elements that makes this fork extremely good at tracking small bumps and chatter which gives you great traction and isolates you from vibration.
  • Spring Rate Regular (over 65 kg / 143 lbs) or Light (under 70 kg / 154 lbs)
    This should be used as a reference. If you’re an aggressive rider it’s likely that you’d prefer the “Regular” stiffness, even though you weigh less than 70kg. You won’t lose any of the small bump compliance.
  • Axle 15 mm Lauf Thru-Axle
    We supply all forks with our own axles. We made a lightweight low profile axle which requires a 6mm allen key. If you prefer a lever, you can replace it with e.g. the RockShox Maxle.
  • Hub Spacing 110 mm
    The TR Boost uses boost hub spacing. You can use a spacer kit to use a non-boost hub, but to fully take advantage of the boost technology you should use a boost hub.
  • Rake 49 mm
    Goes hand in hand with our Axle to Crown length. This fork is designed to “trail” the same as a 80-100 mm suspension fork.
  • Axle to Crown 485 mm
    It’s designed to replace a 100mm XC fork. When you take sag into account on a normal telescopic fork, the axle to crown length is roughly the same.
  • Steerer Tapered 1 1/8" - 1 1/2"
    It’s also possible to fit our forks on bikes that have an oversized headtube (44mm). Then the lower bearing needs to be changed to a 1.5”. Uncut steerer length 250mm.
  • Minimum Rotor Size 180 mm
    180mm is minimum but if you prefer a larger rotor, spacers can be used.
  • Rider Weight Limit 110 kg
    This is your weight in riding gear.
  • Colour Naked Carbon/Matt Black
