Our Prospector is getting two new colours for the first time in five years: Olive Green and Teal — same legendary specs, just fresh new looks!

Olive green is a great neutral that pairs well with silver or black components, and looks great with tan wall tires if that’s what you’re into.

Teal is a throwback to our first production run of Prospectors and a tribute to the 10th anniversary of our flagship model. This version is a couple shades darker than the original and makes the gold decals really pop.

Tumbleweed Prospector Frameset 2026 New Colours

Season:2026

Brand:Tumbleweed

Code:TWProspector2026

Note Pre Order - Feb 2026 ( ETA )

Please contact us before ordering with a fork choice and to discuss availability / colours / component choices / hopes and dreams

The Prospector is our timeless and rugged expedition mountain touring bike, designed around the stalwart Rohloff Speedhub drivetrain. It’s a bike designed to be reliable, tough and field serviceable in the harshest of conditions. In the face of ever changing bicycle part standards and the integration of exotic materials, the Prospector is built to last and to buck the trend of short product cycles and throw away upgrade culture. We believe that the most important features of a reliable expedition bike are a comfortable fit, a tough frame/fork, strong wheels, reliable components, and as much tire/mud clearance as possible.

While the Prospector is derailleur & singlespeed compatable it was designed specifically around the Rohloff SPEEDHUB, a 14 speed internally geared drivetrain that has proven itself to be supremely dependable and capable. We've been using Rohloff hubs on our tours for over a decade and tens of thousands of miles through sand, mud, snow and at elevations of up to 18,000' without issue.

The Prospector has several features that separate it from other expedition bikes. We use the best chromoly tubeset available, it's oversized, heat treated, multi-butted with integrated gussets, and it's custom drawn just for the Prospector. A Phil Wood eccentric bottom bracket offers half an inch of bottom bracket height adjustability, custom cast dropouts work seamlessly with the Rohloff hub, and a hollow chainstay yoke maximizes every millimeter of mud and tire clearance to round out a complete package that can take you anywhere in the world with confidence.

Prospector Fork Options

We have three steel fork options for the Prospector: If you don't plan to run suspension, go with options 1 or 2.

Note that the current 'complete bike' ( see below under 'Professional Opinion' ) is now offered with a Hope Pro5 front hub, if you'd like to run a SON dynamo best to choose option 2 or 3 - that would increase the cost of the complete bike to £4600

1. 135mm Quick Release fork with rear disc spacing: The original fork that we offered with the Prospector, uses the same spacing as the frame, allowing you to run two rear wheels on the bike, useful if you run the bike singlespeed ( or even 4 speed? ) and want to run two ( or four ) different gear ratios. Wide hub flanges produce an incredibly strong wheel with great spoke triangulation.

2. 150x15mm thru axle. The modern fatbike front hub standard. This will build you the strongest possible front wheel, and if you don't plan to run a suspension fork on your Prospector (95% of people don't) then this is your best option. Lots of hub options, wide hub flanges for great spoke triangulation and super strong wheels.

3. 110x15mm Boost thru axle: Allows you to swap between rigid and suspension forks without needing to build a new front wheel. If the Prospector wasn't suspension corrected then we probably just make default option the 150x15mm fork since it produces the strongest wheels for an expedition mountain touring bike like the Prospector.

Complete Bike Purchase Process

We build complete bikes in the order that build specs are finalized. Our standard build with the parts list as shown is £4400, we use this as a starting point for your build, and since we custom assemble each bike from the frame up including hand building all of our wheels, there is a wide range of changes that can be made to our standard spec.

Once you place your complete bike order, we put your name on the frame/fork and reach out to start confirming the final spec for your bike. Once we have finalized the build spec, we send over an invoice for the final balance due if there are any upgrades added on. Once the final invoice is paid, your build sheet goes into our build queue and we begin ordering any necessary parts for your bike. Our goal is to have your bike completed and ready to ship within 4 weeks from the time you pay your final invoice, although there can sometimes be unforeseen delays if a component is out of stock from the manufacturer, etc.
