Stooge MK7 Frameset

What We Say...

The MK7 custom builds are now available for pre-order. This much-awaited frame set from Stooge comes in 3 sizes and, as Stooge's exclusive retailer, we have a very limited supply that is quickly selling out! Don't wait to get your hands on one.

What They Say...

The MK7 is here, and by crikes its a bit of a rocker. Here’s some deets – 3 sizes: 16″ (S/M) with 610 ETT,  18″ (M/L) with 625 ETT and 20″ (XL) with 645mm ETT . Boost axles front and rear, rack mounts on the rear triangle and fork. Triple cage mounts on the fork and downtube. Designed primarily around 29, this will also run well with 27.5+. For best results in 29er mode run a 3.00 or 3.25 front tyre and a 2.6 or 2.8 on the rear.  For clarity on rear tyre size, i’m running a Terravail Coronado in 2.8 on a Velocity Dually i40 rim and the clearance is good.  On a 30 or 35mm rim it may well be that a full 3″ tyre might fit on the rear, though the proof will be in the pudding and its not something i’ve tried yet.

The big change this time around is the sizing.  For the first time we have 3 sizes.  The 16″ Is basically the same size as the old 18 but with a shorter seat tube to allow longer droppers and will be great for shorter riders and those wanting a smaller, more flickable ride.  If you’re 5’9 or less it’ll be a great size and should be good for anyone down to 5’6.   The 18″ is now 15mm longer than the old frame, with a 625mm ETT. This size will still suit the majority of riders from 5’9 up to 6’1.   If you’re on the borderline between the 16 and 18 then ask yourself if you prefer a longer cockpit and base your decision on that. There’s also a new XL (20″) size which has a 645mm ETT, taller head tube and a 20″ seat tube.  I’d only recommend this for riders 6’2 and over.

In addition to the updated sizing, the MK7 will also run with a Super-Duty version of the biplane fork with 65mm offset, so heading back towards the MK4 vibe.   The Dirt Tracker was the first of my frames to use the 65 offset with a 66 degree head angle and it really is something else when it comes to light yet stable steering, so it made sense to let the MK7 reap the rewards.

In short, the mission remains the same, to keep producing framesets that transcend the humble status of the rigid bike, and turn us mere mortals into the golden gods of the hills, or something like that. The MK7 will make a great rigid trail bike and shreddy bikepacking steed. In fact, its so good it’s predecessor won the 2023 bike of the year award over at Bikepacking.com. Here’s what Logan had to say about it….

‘As I see it, Andy’s obsession with building the perfect rigid mountain bike paid off in spades. Like the band it’s named after, the MK6 is punchy, lively, raw, and is simultaneously ahead of and behind the times. If someone asked me to pick just one bike to spend the rest of my life with today, it would definitely be this one.’

Framesets include – frame, forks, EBB insert, bolt on dropouts, allen key thru axles, all mounting bolts, seatclamp.

Here are some numbers that might be useful if you’re looking to collect some parts:

Seatpost size – 31.6 mm. Minimum insertion required of 150mm.

Hub sizes – Rear 12×148, Front 15 x 110

Headset – 1 1/8th” AKA EC34

BB standard is 73mm threaded.

Brake mounts are IS, so choose the IS to Post adapter that goes with whatever size rotors you’re planning on running. Talking of which, max rotor for the front is 203mm, max for the rear is 185.

Chainsets – if you’re running gears then a Boost spaced chainset is the way forward, we’re talking a 51 – 55mm chainline. I’d go for the 51. For single speed or keeping it hardy with 8/9 speed then any non boost size will also work fine.
Max chainring size – 36t
Running square taper cranks? – 73×121 with gears, 73 x 118 will also work fine.

NB:  all steel Stooge framesets have a 2 year warranty for the original owner, this is valid from the day you take delivery of the frameset.
