The new Mason RAW hardtail. View and First Ride Review

Today, those achingly-cool folks at Mason Cycles are launching the Mason RAW, a steel hardtail. If you’re surprised that Mason hasn’t already got a mountain bike in its range, then join the club. However, it’s not a completely new direction for founder and designer, Dom Mason. Dom cut his designing teeth making some great hardtails for Kinesis, before setting out on his own to start Mason Cycles.

The Mason RAW has been long in the development and this look-and-see approach has seen Mason avoid the worst of the geometry growing-pains of recent years so the new hardtail comes out looking pretty on-spec for how riders today want their hardtails. I was lucky enough to get a pre-launch invite to try a new Mason RAW on some of the trails around some Lakeland trails. My first ride impressions are below, but first, let’s look at what the new RAW is (and isn’t…)

The Frame


The Mason RAW is a steel hardtail, handmade and built-up in Europe. The tubing is from Dedacciai in Italy and Reynolds in the UK. The tubes are welded in small batches by Five Land Bikes in Scotland, which also handles the beautiful wet paint job. (As in, paint is sprayed on rather than being powder-coated. This gives a much glossier finish, aided by a top coat of hi-gloss lacquer to protect the paint layer. Frames have eCoat corrosion treatment, inside and out to stop and nasty rust worms. Despite the shiny looks, Mason intends the RAW to be used hard and often.

As well as Dom’s Kinesis pedigree, Mason Cycles also has off-road roots in its ISO (In Search Of) drop-handlebar adventure bike, which has been used by team rider (and all round long-distance honch) Josh Ibbett. It was Josh’s push for a bike to race events like the Highland Trail 550 and Great British Divide that helped form the basis for the direction Mason RAW.

What the RAW isn’t, is a low-slung, woodsy jump bike. Instead, the Mason RAW has been designed to take big 29in tyres, as much (or little) luggage as you want, thanks to a more level top tube for bag room, and many, many fixing points for bags. There are semi-custom options too, for riders wanting top tube bag mounts, or external-fit, male bottle bosses and nuts on the seat tube, to allow full dropper (or dropped) seat post insertion on the smaller sizes. Dropper routing is internal.

Internal cabling ‘where it makes sense’ and room for all sorts of bags.

As Mason says: “All bottle/bag/accessory eyelets and convertible internal routing is standard within frame price. No hidden costs. Cable/hose routing internal where it makes sense.”

About now, you’d be asking for some geometry, so, for a Medium (with a 430mm seat tube) you’d get a roomy 451mm reach (471mm on the Large), and angles of 66°/75° (virtual seat tube). The bike is designed for a 120mm fork, with a SID Ultimate being specced (assuming they can get any). The frame will come in four sizes – S to XL, to fit riders from 5ft 3in up to 6ft 6in.

Smaller seat tubes can have this external bottle cage bolt/nut instead of an internal boss to allow dropper post insertion.

Colours: Vela (which is the stone colour), Filter Yellow, Sensor Blue

Prices: The Mason RAW comes in several specs. The base frame and accessories is £1695, the RAW with RockShox SID Ultimate is £2,395. An SLX build is £3795 with the range-topping XT Launch build coming in at £4195. All frames and bikes come with Deda Elementi headset, Mason seat clamp, a beautiful Mason head badge, full ‘black stainless’ bolt sets, all frame inserts and a natty 3D printed Mason chainstay protector. There’s also the cost-free option of male threaded seat tube bottle mounts (above) and a top tube mount or not.

The Mason RAW first ride

At 5ft 9in/175cm, I’m right on the cusp of most medium and large divisions, and that’s true of the Mason RAW. The medium I rode is good for 5ft 5in up to 5ft 9in, while the size large is 5ft 8in to 6ft 2in. Hopping on the medium, though, gave that modern geometry feel of a bike that initially feels a little short, thanks to the steeper seat angle, but a quick ride round the block showed it to be very well balanced, with just the right amount of weight on the grips on longer flat sections. This is an important factor on a bike that’s intended for that ‘Fast, far’ mindset.
The inevitable product-sourcing issues meant that some of the bikes we rode weren’t quite 100% on-spec, but they were close enough to get a good idea. Interestingly, Mason will fit whatever chainring and cassette you want, when you order it, which is a very useful feature, given that what works for South Downs epics won’t necessarily cut it in the Lakes.

Putting the ‘grr’ in ‘gripped’.

Just stood still, the Mason RAW has a very neat, classy look: the beautiful curve of the seatstays down to the bolt-thru rear dropouts, the shiny head badge, the neat (and informative!) decals around the frame and that very, very shiny paintjob. It seems a shame to go and get it dirty, but that’s what it’s meant for, so we set off from our lakeside cafe and took off up into the hills.

As I mentioned, the steady-away riding position of the RAW is very comfortable. After all, you don’t want a front-weighted riding position if you’ve got 500 miles of Scottish back roads and singletrack ahead of you.

Great front and rear balance rewards a good rider

The trail soon kicked up and gears were grabbed, until none were left to grab. The leaf-slick, crazy paving trail made traction hard to find, but it also showed the balance and poise of the Mason. The fore-aft position felt very sensitive (and responsive) to weight shifts. The difference between a spinning back wheel and traction was surprisingly easy to feel and manage. Eventually, though, everyone was off and pushing. It was here that I appreciated the lack of sticky-out rackmount bolts (they’re on the inward curve of the seatstays) and the rear brake, tucked into the rear triangle.

Dom regales journos with epic tales of the RAW’s development (and spicy pasties too…)

At our lunchtime debrief, Dom Mason had said that he’d had to relearn what modern mountain bikes were doing. Having been away from the ‘scene’ for the last half-dozen years, while working on Mason’s adventure bike line, he had come to hardtail design fresh and free from the incremental improvements that other manufacturers had been playing catch-up on in the last decade. When he last designed a hardtail for Kinesis, headtube angles were still in the 70s and dropper posts weren’t as omnipresent as they are now. This fresh start seems obvious in the bike’s ride, as there are no legacy quirks to worry about, as the RAW was designed from a completely blank slate with some 29in wheels on it and nothing else.

Chipps, getting warmed up on the climbs.

The design of the RAW frame took a lot longer than intended, not helped by his Italian tubing and frame factories having to close completely for two months during the worst of Covid. However, this did help Dom to nurture his relationship with the builders at Five Land, who he’d met at Grinduro in Arran. By the time the factories had reopened, Dom was ready to give them the job of making the Mason RAW. And, indeed, the welding on it is faultless looking, with neat downtube gussets and tricky welds like the inboard rear brake mount done perfectly.

While the Mason ISO has won many fans in the gravel riding and racing world, Dom knew that riding ‘proper’ off road on a drop bar, rigid bike ‘is hard and bumpy’ so the RAW would be designed around a suspension fork.

Sit/stand/fore/aft – the RAW takes body English very well

The neat balance of the RAW does help with riding on tricky terrain, as a subtle weight shift can either weight the forks for grip or lighten the front wheel to smooth bumps or hop over obstacles. There’s a really nice compact and ‘together’ feel to the bike, like you’re riding something that works as a whole. The exaggerated, dynamic body shifts that are sometimes needed to bully a modern slackgnar bike between linked turns isn’t needed here. The Mason RAW rides with a neater, cleaner feel. Welcome back to the work of picking lines… not that the RAW doesn’t take on the bumps, but good lines are rewarded with extra exit speed. Smoother, contouring trails are a joy and it was fun cornering at a speed that put the tyres into controllable drifts. If you’re on the gas and you have the traction, it’s going to be a blast to thread between the trees.

Bring back dry, summer trails!

Our wet and slippy Lakeland test loop was probably a world away from the dappled and dusty, south-coast woodsy singletrack that that RAW was doubtless trialled on, but it handled the day just fine. Give the bike some confidence and enthusiasm and it’ll reward you with an engaging ride.

Just because it’s beautiful, doesn’t mean you need to baby it…

The Mason RAW is going to appeal strongly to a subset of riders, while many others won’t really see the point. It’s certainly very expensive when compared to other steel hardtails, but it depends on what value you put on things. Some riders will just see an expensive hardtail. Others will put store in the ‘UK-welded from UK and EU tubing and frame components’ aspect, or the simply stunning paintjob. Some riders will appreciate the support that Mason has given to riders like Josh Ibbett and to the whole adventure racing scene in general and will shop accordingly.

Josh’s own bike was looking very unscathed, despite months of prototype-test bashing

The bike has a well thought-out layout, with everything fitting together well. The chainstays had plenty of room for some 2.5in WT Maxxis Minions, with claimed room for 29 x 2.6in tyres. The cables all exit from neatly integrated ports and skirt around the head tube without cable rub. There are even some concealed rack/mudguard eyes on the insides of the rear stays. It all seems to come from practical experience, rather than just going through a ‘boss and braze-on) catalogue and ticking boxes.

A painted frame comes in at 2.5kg/5.5lbs, which, in these days of 900g carbon hardtails, is a substantial chunk – and again, it may turn off riders wanting a frame they can race XC at the weekends on. In fact, that’s the same weight as the Salsa hardtail I had in 1991. However, until that frame, this frame takes massive wheels and tyres, all the luggage and it’ll still go round corners. Anyone who’s ridden a too-light steel frame can tell you how unnerving it is to have your head tube pointing in a different direction to your back wheel. The RAW has been designed to travel a long way, fully loaded at a fast speed, so durability has been woven into it from the start. Unless you’ve lost every pound you can from body and gear, then it’s unlikely that you’ll suffer from the frame weight.

Who knows what Josh had in there? Didn’t seem to slow him down though…

It’s hard to get a hardtail to do something shocking or surprising, especially now that longer frame reaches and slacker angles mean that most hardtails handle themselves well on most trails. However, Mason has focussed the Mason RAW onto a particular part of the hardtail world – that of a woodland singletrack smasher and a horizon-bringer and it has done that bit very, very well. You’ll either see the value in the design, the brand and the components, or you won’t. And for those that do, they’ll have a steel hardtail that still has the power to draw a crowd, which is a tough thing to do these days.

This kind of thing…

3 Things I’d Improve

  • Despite the tough clearcoat, I’d still want to Invisiframe the bike to protect from bag strap-rub
  • Mason decided against the extra engineering (and metalwork!) needed to fit SRAM’s Universal Derailleur Hanger. For global travellers, this means always carrying a spare.
  • It costs what it costs, but many riders won’t be able to afford it. And the frame weight is more than you’d expect for the price.

3 Things I liked

  • The poised and precise feeling. The Mason RAW certainly isn’t twitchy, but it responds beautifully to subtle inputs.
  • The fit and finish of the final frames is so good. Even wet and dirty, they clean up quickly, ready for another lap. Seems a shame to take them out in the rough and tumble of the trails, but hopefully that’s what they’ll be used for.
  • Mason really stands behind the riding it promotes: sponsoring riders and events. It really live the ‘fast and far adventures’ motto.

Overall:

The Mason RAW is a particular bike for a particular rider and range of riding. It’s a non-jumpy, top-end steel hardtail, which will instantly limit its appeal. The price, too, will put off some other riders. What you do get, though, is a capable, tough, trail hardtail that is designed to work and balance well, whether that’s on a summer of chalky South Downs singletrack, some map-crossing big days out or that cross-a-country race that needs ultimate reliability when you’ve had two hours of sleep. Mason seems to have hit this balance well, and its high standing in the adventure riding and racing world should see some instant fans. I only hope that riders will try to put the RAW to the test on a regular basis and not just ride on them to the coffee shop for mutual appreciation. It may be pretty, but it’s a bike with some untapped potential.
