Specialized Turbo Creo 2 Comp

The Specialized Turbo Creo 2 Comp is aimed at riders who want subtle electric help on long mixed-surface days rather than a full-power e-bike. You still pedal a drop-bar bike, but Specialized's 1.2 SL motor, claimed at 320 Watts and 50Nm, helps on steep climbs, into headwinds and over extra distance. High-volume 700x50c tyres, Future Shock 3.2 and a 50mm X-Fusion Manic dropper give it genuine gravel manners, so one bike can cover tarmac, farm tracks and light bikepacking.

It is the current UK model, sold as the Turbo Creo 2 Comp with Shimano GRX Di2 at an official original UK RRP of £4,999.

The GRX Di2 carbon build

This Comp uses a FACT 11r carbon frame on Specialized's Creo 2 mixed-surface electric platform. The motor, fully integrated 320Wh SL1-320 battery, MasterMind TCU and 12x142mm rear axle sit inside that generation, with internal routing and mounts for a rack and mudguards. Those mounts are compatibility points. The accessories themselves are not listed as fitted.

Shimano GRX Di2 does the shifting, with RX715/717 levers, an RD-RX717 12-speed rear derailleur, a 44t chainring and GRX RX410 hydraulic discs. Carbon, electronic shifting, Future Shock 3.2 and the dropper are why this Comp is £1,000 more at RRP than the separate alloy Comp E5, which uses mechanical Apex Eagle, Future Shock 2.0 and a fixed seatpost. It sits below the Expert carbon builds in the range.

Climbing help and mixed-surface control

Assistance is strong enough for very steep climbs, yet it arrives in a natural, rider-led way. MicroTune lets you trim support from the handlebar remote, and the MasterMind TCU talks to the Specialized app over ANT+ and Bluetooth. Specialized claims up to five hours of assisted riding, though assistance level, wind, climbing and your own input all change that figure.

On the road, endurance geometry and 20mm of Future Shock 3.2 travel take the edge off broken surfaces without the bob of a conventional suspension fork. Leave the tarmac and the 700x50c Tracer TLR tyres, plus stated clearance up to 29x2.2, give you far more tyre than a typical electric road bike. The dropper is the extra that matters on a steep, loose descent: drop the saddle 50mm and you can move your weight back without stopping.

Specialized quotes 14.65 kg for a size 56. That keeps it lively for an e-bike with this tyre volume, but UK law cuts assistance at 15.5mph, so stronger road riders will feel the mass once they are above the limit.

Charging, tyres and upkeep

The 44t chainring and 10-51t cassette give a very low climbing gear, which suits the 50Nm motor on long hills. GRX Di2 adds a small shifter battery to keep charged beside the 320Wh main pack. Because that pack is fully integrated, convenient bike-level charging and dry indoor storage matter more than they would with a removable battery.

A Specialized Range Extender is compatible but not fitted. It stretches longer days, at the cost of a bottle-cage mount and extra weight. DT Swiss G540 rims and Tracer TLR tyres are tubeless-ready and come with inner tubes, so converting is an ownership choice. Bias the bike toward tarmac with a faster, narrower tyre, or toward rougher tracks within the 29x2.2 limit. Plan for ordinary chain, pad and cassette wear, plus specialist support for the motor, battery, software and Future Shock hardware.

Frame sizes run 49, 52, 54, 56, 58 and 61, with crank length, bar width, stem and seatpost changing through the range. Manufacturer height bands overlap, especially around 54, 56 and 58, so reach and stack are the figures to trust rather than height alone.

Earlier SRAM Comp bikes

The earlier Turbo Creo 2 Comp on this carbon generation used SRAM Apex/X1 Eagle AXS wireless mullet shifting and 700x47c tyres. Leftover or used SRAM listings are the same Creo 2 carbon platform with a different groupset and a slightly narrower stock tyre, not an older frame generation.

With the right size, the current Comp can turn a hilly loop or a gravel day into a ride you finish fresher, without giving up drop bars on the way home.
