Wilde Supertramp Steel Fork — 29in Bikepacking, Disc Brake, Black

Wilde Supertramp Steel Fork — more capability, bolted onto the bike you already own

Most upgrades make a bike slightly better at what it already does. This one changes what the bike is for. Swap a stock rigid fork or a tired suspension unit for the Supertramp fork and a competent hardtail becomes an expedition machine: room for a 29 x 2.8in tyre, cargo cages on both blades, a low rider or platform rack at mid-blade, fenders top and bottom, and a dynamo wire running inside the leg where nothing can snag it.

It is powder coated black, and that matters more on a part sold on its own than it does on a frameset. Powder coat is the tougher of the two finishes — it shrugs off the rock strikes and strap abrasion that a fork on a loaded bikepacking build collects by the week — and black is the one colour that disappears cleanly onto somebody else's frame.

Built around carrying weight

The mounting pattern is the point of this fork. Three-pack mounts on each blade take cargo cages, dry bags or bottles. A mid-blade rack mount accepts low riders or platform racks. Double eyelets at the fork ends let a rack and a fender share the same fixing without a stack of spacers. And the blades carry mounts for the Surly 8-pack and 24-pack racks, which is the practical detail that decides a lot of bikepacking builds — those two racks are the reference standard for front cargo, and a fork that takes them natively saves you a bracket, a clamp and an argument.

Internal dynamo routing

The wire runs inside the blade rather than cable-tied down the outside. On a bike that spends nights out, that is one less thing to catch on a branch, one less rub point wearing through the finish over a winter, and a considerably tidier front end.

The numbers that decide whether it fits

Two figures matter before anything else. The steerer is 1 1/8in straight, not tapered — so the frame needs a straight head tube, which rules out most modern trail bikes and rules in steel frames, older hardtails and purpose-built ATB frames. And the axle-to-crown is 450 mm, which is in suspension-corrected territory: on a frame drawn around a rigid fork of, say, 400 mm, this will raise the front end and slacken the angles noticeably.

The steerer arrives at 350 mm, long enough for almost any frame and stack height, and is cut to length on fitting.

What is included

The fork only. Headset, crown race, star nut or expander, thru axle, brake caliper and adaptor are sold separately.

The frame it was drawn for

This is the fork from the Wilde Supertramp frameset, Wilde's bikepacking and all-terrain platform. That frameset already ships with its own fork, so you do not need to add this one to it. Buy it as a spare, as a deliberate black-on-Dirt-Champagne contrast, or — far more often — to bring an existing bike up to the same standard.

Frequently asked questions

Will it fit my bike?
Three things decide it. Your frame needs a straight 1 1/8in head tube, because this steerer is not tapered. Your front hub needs to be Boost 110 mm. And your frame should be drawn around a fork of roughly 450 mm axle to crown — either a suspension fork of about 100 mm travel, or a rigid fork of similar length. If your current fork is much shorter, this one will raise the front, slacken the head angle and lift the bottom bracket. Send us your frame model and current fork and we will tell you honestly whether it works.

Can I run a suspension fork's axle and rotor?
Boost 110 mm spacing means most modern Boost front wheels drop straight in, and the caliper mount takes up to a 180 mm rotor, which is ample for a loaded bike. Check the thru axle standard of your existing hub before ordering — that is the one part not included.

What tyres will actually fit?
Up to 29 x 2.8in, which is genuine plus territory rather than a marketing figure. If you are running fenders as well, drop half an inch or so of width to leave somewhere for mud to go. The clearance is what makes this fork worth fitting to a bike that currently maxes out at 2.3in.

Which racks and cages does it take?
Three-pack mounts on both blades for cargo cages, dry bag cradles or oversized bottles. A mid-blade mount for low riders or platform racks. Double eyelets at the dropouts for a rack and a fender together. And native mounting for the Surly 8-pack and 24-pack racks, which covers most front cargo setups without adaptors.

Will it match a Dirt Champagne Supertramp?
No — this fork is black, and we would rather be clear about it. Geometrically it is the same fork as the one supplied with the frameset, so it fits and rides identically, but it is a contrast rather than a colour match. Black against Dirt Champagne is a good-looking combination and plenty of people choose it deliberately, but it is a choice, not an accident.

Can you fit it for me?
Yes. Our workshop at L'Hirondelle Bike Shop in Meppel cuts steerers, presses crown races, sets up headsets and aligns disc calipers as routine work, and we can run a dynamo wire through the internal routing at the same time. Bring the bike in or send us the frame — a steerer cut wrong is a steerer cut once.
