We’ve been lucky enough to have the all new Transition Spur in for an exclusive first ride test ahead of its launch. The brand new Transition Spur sees Transition entering a new sector of the market and the Spur is designed as a 29” wheeled, short travel, fast, fun and capable trail bike. Recently there seems to have been an explosion of fast and capable XC focused bikes and this is Transition’s take on the genre.

With 120mm front and rear and a full carbon frame, the Transition Spur is designed to climb like an XC race bike, but with angles and components capable enough of getting you back to the bottom, down whichever trail you like. Then climb back up and do it again. Where some bikes in the Transition range may seem like they favour descending over climbing, the Spur is all about getting to the top under your own steam.
Based around a brand new full Japanese Toray carbon frame that is manufactured using latex EPS moulding in Transition’s new carbon factory, the Spur delivers 120mm rear travel via their GiddyUP suspension system. Where the rest of the Transition range uses a four bar Horst Link system, the GiddyUP system on the Spur utilises a carbon tuned pivotless flex stay that allows Transition to get rid of the chainstay pivot helping keep weight to a minimum. Claimed weight for a size M frame with shock is 2500g.
The suspension is designed to have around 30% progression through the stroke so it can remain supple at the start while still maintaining plenty of support for hard cornering and pumping trails, and absorbing large impacts. It’s also been designed to work with a sag range from 25% – 30% allowing riders to tune the feel of the bike. Similarly the anti-squat has been tuned to for optimum pedalling performance, but not at the expense of suspension performance.
Designed to be ridden up, across and down whichever hills, mountain and trails you choose, the Transition Spur is definitely long and low, with reach on our size large test bike being 480mm and a BB height of 335mm. The head angle is a slack 66 degrees which is paired with a steep seat angle (76.7 – 75.6 degrees depending on size) for efficient climbing and confident descending. Chainstay length across the range stays at a compact and nimble 435mm.
The Spur comes in three pre-specced models along with a frame only option, and two colour options – Black Powder and Deep Sea Green. All full builds come with SRAM drivetrains and RockShox suspension with a starting price of £4,999.95 for the GX build, up to £8,999.95 for the top end AXS XX1 equipped super build. Frame pricing with SID Luxe Ultimate shock is £2,999.95.
All models in the range utilise the same carbon frame with the differences just coming in the spec of the complete bikes. The frame features fully guided internal rear mech routing, but fully external rear brake hose guides making drivetrain and brake maintenance nice and easy.
The headtube on the Spur is designed for press in headset cups to allow for the use of adjustable angle headsets for those that want to push the geo even further. There’s a threaded bottom bracket that will keep a lot of people happy and the frame features not one, but two water bottle mounts on the downtube (one on top, one under), along with an ‘accessory mount’ under the top tube so you can ride fast and light with minimal baggage.
Transition has also gone with a collet main pivot axle, with a bearing shield, for the main pivot to maximise the weather proofing and keep the suspension running smoother for longer. Another conscious decision in the design was to make the seat post insertion as big as possible to allow the use of longer droppers across the range. Our size large came specced with a 180mm dropper but there’s plenty of room to push this further.
Out back there’s clearance for a 2.4” tyre and a nice neat moulded chainstay protector to keep the noise down and protect from chain slap. All the frames in the range are covered under Transition’s lifetime warranty.
Transition Spur Specification
The model we’ve had on test is a size large, middle of the range X01 build that comes in at £5,999.95:
- Rear Shock: RockShox SIDLuxe Ultimate 190 x 45
- Fork: RockShox SID Ultimate 120mm
- Headset: Cane Creek 40 Series
- Stem: Race Face Turbine R 50mm
- Bar: OneUp Carbon 800 x 20mm
- Grips: Sensus Lite
- Saddle: ANVL Forge Ti
- Seatpost: OneUP dropper Post 180mm
- Brakes: SRAM G2 RSC
- Rotors: SRAM Centreline (180/160mm)
- Shifter: SRAM XO1 Eagle
- Derailleur: SRAM XO1 Eagle
- Cassette: SRAM XG
- Chain: SRAM XO1 Eagle
- Crankset: SRAM X1 Carbon
- Wheelset: DT Swiss XR 1700 Spline 25
- Tyre (front): Maxxis Dissector 29 x 2.4 3C Exo
- Tyre (rear): Maxxis Rekon 29 x 2.4 3C EXO
All bikes in the range use the new RockShox SID suspension and the XO1 build comes adorned with a SID Ultimate up front delivering 120mm of race inspired travel. The Ultimate features the new Charger Race Day damper that is the lightest RockShox has ever produced and also features a proper solid lockout, perfect for fire road grinds or sprinting up hills.
This is paired out back with a SIDLuxe Ultimate, that again delivers 120mm of XC focused trail taming bounce. As with the fork, the SIDLuxe Ultimate was borne from XC racing and features a lightweight design with progressive air spring, along with minimal high speed damping to eliminate harshness and keep things under control on super rough terrain.
As you might have guessed by the model name, our test bike features a full SRAM XO1 drivetrain, including X1 carbon cranks and a XO1 50 tooth (production spec will feature the 2021 52 tooth) cassette giving plenty of stiffness for sprinting up climbs and into corners.
SRAM are also on call for stopping with a set of 4 pot G2 RSC brakes offering independent reach and bite point adjustment. Those 4 piston calipers clamp onto SRAM centreline rotors with a 180mm up front and an XC looking 160mm out back.
SRAM G2 levers… and 4 piston calipers
Rolling on 29” wheels, the Spur is specced with a set of DT Swiss XR1700 Spline 25 wheels. These feature DT’s 350 Ratchet hubs and are laced to lightweight aluminium rims with a 25mm internal width. Wrapping those are a grippy Maxxis Dissector 29 x 2.4 3C EXO on the front and fast rolling Maxxis Rekon 29 x 2.4 3C EXO on the rear.
Rounding out the spec list is a raft of components from other fellow US and Canadian brands. The seatpost is provided by OneUp components, with a V2 180 dropper seatpost and V2 lever. Cockpit is a mix of brands with a OneUp 800mm wide, 20mm rise, carbon bar being held in place with a Race Face Turbine R 50mm stem. Finishing off the contact points is an ANVL components Ti railed Forge saddle and a set of Sensus Lite grips.
All this added carbon goodness, and XC componentry adds up to an impressive out of the box weight of 26.89lbs with inner tubes. Once then tyres had been tubeless’d with the Stans Valves and sealant that came with the bike, this then dropped to a super light 26.01lbs.

Hot damn, that makes that Yeti thing look untidy.
Well, I know where my next 6 grand is going… it’s going on food and bills and grown up stuff like that.
But if I had a ‘spare’ 6 grand…
Been dreaming about bikes like this recently as my smuggler is great but a bit of a porker……… sadly 5 or 6 grand means I’m waiting a few years for a used one!
Amazing-looking bike.
I had to look up the Dissector tyre!
That’s a really nice looking bike. Noticed a few of these now where the top tube flows into the seat stays in one line, and I’ve got to say, it’s a pretty neat design
Nice bike, I like transition bikes but they have seemed quite heavy until now..love short travel cc/trail bikes…£6000 though best sell a kidney, oh hold on only have one that works…
I’m logged in but can’t read the review?
@richmtb have you clicked the ‘Verdict’ button to go to the next page?
@Hannah Dobson
Yep, still nothing

@richmtb not sure what the problem is there as it doesn’t seem to be a general issue. Please can you head here https://singletrackworld.com/help so tech can look into it?
Not letting me see the rest either.
Great looking bike. Remarkably similar in concept to the NS Bikes Synonym TR. The angles are pretty much identical, although this comes with a slightly shorter wheelbase. Although I dream about bikes with a little more travel and capability, I suspect something like this is pretty close to what would actually suit most of my riding best.
