Swarf Contour Prototype frame and kit
Outstanding attention to detail gives the Contour the feel of a highly polished product, making it easy to forget that my sample was just a prototype (Swarf hopes to have the finished product ready early summer ).
The mainframe and swingarm are lovingly crafted from various types of steel tubing (Reynolds 853 DZB top and down tubes, Reynolds 631 seat and head tubes, Dedacciai chainstays, 4130 seatstays), and the frame has amazingly clean lines, with a built-in seat clamp and neat and well-thought-out external routing for the rear brake hose and gear cable.
I particularly like the way the top tube and seatstays form a single straight line along the length of the bike.
Swarf has opted for a single-pivot suspension layout combined with a linkage-actuated shock. The swingarm has 6mm of vertical flex built in, which eliminates the need for a pivot above the dropouts.
Ady, Swarf’s owner, says he spent a long time engineering the design so that it worked with the smallest amount of flex possible. He’s also configured the suspension to be exceptionally progressive.
The rocker link on the prototype was machined from 6082-T6 aluminium, but production bikes will lose the seatstay brace to improve tyre clearance and use a carbon-fibre link instead to maintain stiffness.
A range of rear shocks will be available, including the Cane Creek DBAir IL fitted here. The frame itself weighs a claimed 3.35kg (Large, without shock).
Vital statistics include 115mm of rear wheel travel, a 67-degree head angle and a steep 75.5-degree seat angle. My large sample had a long 465mm reach and 1,210mm wheelbase, plus 445mm chainstays.
The Contour will only be available as a frame, but I can see a lot of buyers opting for a similar build to this one, which included a RockShox Pike RCT3 fork and Reverb post, and Shimano XT brakes and gearing.
Light Bicycle carbon wheels with a 31.6mm internal width give a nice wide tyre profile and felt neither especially twangy nor overly stiff.
Swarf Contour Prototype ride impressions
Swing a leg over the Swarf and, even in the car park, you’d think it’s got more than 115mm of travel, thanks to the plush shock and impressively progressive rear end.
On the trail, it’s a blast. The suspension fills you with confidence that it’ll handle anything you throw its way. Put rock gardens, roots and massive compressions in front of the Contour and it’ll chomp through them without making a fuss.
As a bonus, it’s got great small-bump compliance too, because the progressiveness of the rear end means you can run lower shock pressures than normal.
Despite its smooth, plush feel, it’s no blancmange on the trail. The steel frame is forgiving and takes some of the harshness out of washboard ripples and trail chatter, but it still goes exactly where you point it.
That bump-dulling ability doesn’t translate to twanginess either. It’s stiff, strong and supple. While the 67-degree head angle sounds steep compared to the latest 650b enduro bikes, it’s relatively slack for a short-travel 29er.
Even when ragging down rough straights or steep sections, I didn’t feel like I was getting pitched forward or that the front was tucking under.
If you’re in the market for a handmade trail bike that punches well above its weight, the Swarf 29er’s special ride and well-thought-out details mean that it needs to be on your radar.
Swarf Contour Prototype verdict
A UK-ready do-it-all trail bike that you can razz hard and it will take the harsh hits like a champ.
