The intriguing Orange Crush MX concept is essentially a mullet hardtail makes sense on paper but what happens when the rubber hits the trail?

Orange Crush MX Pro Ltd need to know

  • 6061-T6 custom butted aluminium frame comes in four sizes and is designed around a 140mm-travel suspension fork
  • LTD edition gets a brushed alloy finish and a Fox 34 Performance fork
  • Shimano SLX 12-speed drivetrain and Deore two-piston disc brakes round out the build
  • Available as a frame only for £600

If you read last month’s MBR magazine, you’ll know that I laid out my thesis for the optimum trail hardtail. For anyone that missed it, here are the Cliffs Notes.

If you are running 2.4in tyres then it’s best to have 29in wheels and benefit from the improved rollover they bring. If, however, it is improved grip and comfort that you want from your cutting edge trail hardtail, no amount of tubing manipulation will match the benefits of bigger tyres. So, I proposed that a mullet hardtail was the way to go. By having a 29in front wheel you get the steering precision you want from a regular 2.5in tyre, and you can run a shorter-travel fork to reduce the geometry variations you typically get on hardtails; making it a win, win in my book.

A 27.5in wheel at the back makes perfect sense for a modern hardtail

By switching to a 27.5in rear wheel with a 2.6in, or even a 2.8in tyre, you get extra cushioning and traction from the higher-volume rubber, but also a stronger rear wheel. No bad thing on a bike with zero rear suspension to absorb the biggest impacts. And this is where running a tyre insert like CushCore would really help too.

To put my theory to the test I started searching for mullet hardtails. Much to my surprise, the only one I could find was the Orange Crush MX. So, as promised, here it is.

Two-piston Deore brakes sacrifice power for reliability of action

Built around a 6061-T6 custom- butted alloy frame, the Orange Crush has always had a softer ride feel than most alloy hardtails, and the Crush S won our Hardcore Hardtail test back in 2015 with a perfect 10 rating. But as brands like Whyte made the switch to larger-volume tyres, the Crush started to slip down the ratings.

Well, it’s back, and it’s not just the tyre and wheel sizes that have been switched up, the geometry and sizing have been updated too. The size large boasts a generous 473mm reach, which actually increases as the fork sags into its travel, so it’s going to feel slightly longer than a full-suspension bike with the same static reach measurement. Standover clearance is equally generous, so the bike never feels like a handful even though the 1,243mm wheelbase gives it a footprint that’s every bit as imposing as modern full-suspension bikes.

Angle of head tube is suitably slack but it could do with trimming down

It’s slack, too; the sub-64° head angle a good match for the 140mm-travel Fox 34 fork. It’s great that Orange hasn’t gone crazy steep on the seat tube, so more of your weight goes into flexing it rather than trying to compress it. This makes complete sense, because with no rear suspension to sag as you climb, there’s no need to have 78° seat angle on a hardtail, and I’d even argue that it actually makes the ride less forgiving.

Best of all, the BB height on the Orange Crush MX sneaks in under 300mm, something that none of the bikes in last month’s test managed. Yes, even with 170mm cranks, I clipped the pedals a couple of times, but no more than I would when riding the same trails on a regular full-suspension bike.

SLX rear mech is a good match for the 32t Race Face chainset

So the frame is dialled, but what about the build kit? For a £2.5k bike there’s nothing fancy but it’s all functional. I think it’s cool too, that there’s not a single carbon component to be found. The alloy Burgtec RideWide Enduro handlebar has a great profile, as does the classic WTB Silverado saddle. Orange mixes a Race Face Ride chainset with a 12-speed Shimano SLX drivetrain to great effect and while the two-piston

Deore brakes have slightly less power than Shimano’s four-piston units, they have better modulation and don’t seem to be plagued by the brand’s variable bite point problem. Which, I have to say, is a bugbear of mine.

How it rides

I was super-excited when the Orange Crush MX arrived. Sure, it had a slightly longer-travel fork than the ideal trail hardtail I’d outlined last month, and I’d have liked the 2.6in Maxxis Rekon rear tyre in the tougher EXO+ casing, but it was close enough, and I was more interested in the concept of a mullet hardtail and didn’t want to get distracted by minor details.

It’s somewhat ironic then, that a component part as small and insignificant as the upper headset bearing cover almost proved the undoing of this bike. The 10mm conical bearing cover prevented me from getting the handlebar low enough to properly weight the front end. Now, it’s worth pointing out that if I’d been on the size medium, this wouldn’t have been an issue, as the head tube is 10mm shorter.

800mm-wide Burgtec bar has perfect profile

So my first ride on the MX left me feeling a little deflated. I promptly ditched the bearing cover and slammed the stem, which instantly had me power wheelieing out of corners rather than hanging off the back of the bike. The lower bar position allowed me to pull up harder on the bar when sprinting, while offering an altogether more centered riding position for hard charging.

The Crush MX isn’t only for the hardcore trail rider though. The overall riding position is great for big days in the saddle, and that’s where the 2.6in rear tyre really comes into its own. Not only is it more comfortable, the tyre’s ability to wrap around rather than ping off roots and rocks, really increases traction, be it climbing or braking. Sure, the low-profile tread on the Rekon lacks bite, but it keeps the tempo and efficiency high, which is exactly what you want from a hardtail.

Up front, the 140mm Fox 34 fork is super-sensitive, but by running it a little firmer, you can get it to run higher in its travel until you hit something hard. This, combined with the progressive geometry and sizing, makes the Crush MX a stable but thoroughly engaging ride. Could it be improved upon? Well, I could argue that if a 27.5in wheel with a 2.6in tyre is good, maybe a 2.8in tyre is even better. I suspect there’ll be more mullet hardtails springing up soon, but for now, Orange is ahead of the curve and the Crush MX ticks virtually all the right boxes.
