First Look: Transition’s Spur Kicks Trail Bikes Into High Gear

New 120mm lightweight trail bike with long and slack geometry


Transition is best known for its long and slack trail and enduro bikes, and the quirky launch videos that accompany their release. So it came as a bit of surprise when we learned the Bellingham, Washington-based brand was gearing up to launch a new model that borders on a marathon cross-country bike. The Spur is a lightweight, 120mm trail bike that looks like it would be equally at home at the start line of cross-country stage races like the BC Bike Race or on an all-day adventure through the mountains. Read on for all the details.

It’s a sign of the times that short-travel bikes have caught up to Transition’s preferred riding style. This season we’ve seen an impressive fleet of progressive short-travel mountain bikes that obliterate the line between cross-country and trail bikes. The Spur is up to speed with the long, slack geometry we’ve come to expect from Transition, but with additional features intended to shave grams.

Unlike Transition’s other mountain bikes, which feature Horst-Link suspension designs, the Spur eschews the chainstay pivot in favor of a lighter flex-stay. Cannondale and Specialized use similar arrangements on their respective cross-country models, the Scalpel and Epic.

The Spur’s frame features full tube-in-tube routing and a threaded bottom bracket. The carbon frame is constructed from a blend of premium Japanese Toray fiber with 24T, 30T and 40T carbon sheets used to create the right balance of frame stiffness, strength, and impact toughness.

According to Transition, the Spur has an excellent balance of support and small bump sensitivity, with anti-squat tuned to for improved pedaling performance and acceleration. Riders are able to add or remove volume spacers in the rear shock to suit their individual riding style and bottom-out control. In its stock form, the Spur has 120mm of rear-wheel travel with a 190mmx45mm stroke shock. Riders on the XC end of the spectrum can install a  190mmx37.5mm stroke shock to reduce the rear wheel travel to 100mm.

Transition Spur Geometry

The Spur may only have a scant 120mm of rear suspension, but its geometry mirrors that of enduro race bikes from two seasons ago. The slack head angle and steep seat tube angle should make this a very capable machine no matter which side of the mountain this bike is pointed toward.



Spur Build Options And Availability

The Spur is equal parts cross-country and trail bike and the builds reflect this. Complete bikes come equipped with RockShox SID suspension, 29×2.4 EXO casing Maxxis tires, four-piston SRAM G2 brakes, and SRAM’s new wide range 10-52t cassettes.

The price for the frame with shock is $2,999. Complete builds range from $4,999 – $8,999.

    Nice to see Transition and Kona recognize not everyone shuttles and are making bikes for people that like to earn their turns and shred too.

      I know a couple of manufactures are really starting to see this as an emerging type of bike. I am on an Intense Sniper trail, also 120/120 and am usually the first one to the bottom of the trail. I am wishing Intense had this seat tube angle and dropper insertion. So many people over bike and lug their burly unnecessary components all over the place.

        Demoed this, but ended up trailing out my BLur with a 120 step cast and db inline out back. I also have a 150/160 bike to compliment it but will likely bump that bike up to a 170 enduro/wreckoning. Point being, the 120 bikes are now so capable and the 170 bikes can pedal so well it makes covering anything and everything that much easier.
