Specialized Tarmac SL9 Prices Bring Superbike Performance Closer

 

The latest Specialized Tarmac SL9 range makes Specialized’s flagship race-bike platform considerably more attainable. The headline model for many UK cyclists will be the Specialized Tarmac SL9 Comp Shimano 105 Di2, priced at £3,999.

Move up to the Specialized Tarmac SL9 Expert Ultegra Di2 and the price increases to £5,999. For that additional £2,000, riders get a lighter electronic groupset, carbon wheels and a quoted bike weight that is approximately 680g lower.

Both models give cyclists access to the SL9 platform for substantially less than the original £11,999 S-Works launch price. But which represents the better buy, and is the Expert genuinely worth another £2,000?

Specialized Tarmac SL9 Comp 105 Di2, £3,999

The Tarmac SL9 Comp Shimano 105 Di2 is built around Specialized’s FACT 10r carbon frame and uses Shimano’s dependable 12-speed 105 Di2 groupset. Specialized quotes a weight of approximately 8.21kg, although the final figure can vary according to frame size and specification.

Its DT Swiss R470 aluminium wheels are reliable and practical, but they are also the clearest area where the Comp gives something away to the Expert. Riders looking for more speed and a racier appearance may eventually consider upgrading to a deeper carbon wheelset.

That does not make the Comp incomplete. Shimano 105 Di2 delivers fast electronic shifting, hydraulic disc braking and much of the functionality found on the more expensive Ultegra system. For sportive riders, fast club cyclists and anyone buying their first premium carbon race bike, this is likely to be the sweet spot in the range.

Specialized Tarmac SL9 Expert Ultegra Di2, £5,999

The Specialized Tarmac SL9 Expert Ultegra Di2 takes the same high-performance concept and adds components that make it faster and lighter straight out of the box. Its Shimano Ultegra Di2 drivetrain is lighter than 105 Di2, while the supplied Roval C38 carbon wheels provide a meaningful upgrade over the Comp’s aluminium wheelset.

Specialized quotes a weight of approximately 7.53kg, which is around 680g lighter than the Comp. That difference should be noticeable when accelerating, climbing and carrying the bike, although fitness, position and aerodynamics will still have a much greater effect on real-world speed.

The Expert makes most sense for cyclists who already know they would replace the Comp’s wheels. Buying the higher model from the beginning gives you a well-balanced specification without the cost and inconvenience of upgrading individual parts later.

Tarmac SL9 Comp vs Expert Comparison

Is the Tarmac SL9 Expert Worth the Extra £2,000?

The answer depends largely on how much you value the Expert’s carbon wheels. The performance difference between Shimano 105 Di2 and Ultegra Di2 is smaller than the price gap might suggest. Both provide precise electronic shifting, hydraulic braking and the wide range of gears needed for fast British road riding.

The Roval C38 wheels are a more significant upgrade. They reduce weight, improve the Expert’s overall specification and help give it the appearance and feel expected from a bike costing almost £6,000. If you bought the Comp and later added a comparable carbon wheelset, the total price difference between the bikes would become considerably smaller.

However, the Comp leaves £2,000 in your pocket. That could fund a good set of carbon wheels later, a professional bike fit, power meter, clothing and several cycling trips. It also gives you the option to choose wheels that match your preferred rim depth and riding conditions.

Who Should Buy the Tarmac SL9 Comp?

Choose the Specialized Tarmac SL9 Comp 105 Di2 if you want the SL9 frame and electronic shifting at the lowest available price. It is particularly attractive for club riders, sportive cyclists and ambitious amateurs who care more about value than having the lightest complete build.

It is also the better starting point for riders who enjoy selecting their own upgrades. The aluminium wheels can be used for winter riding or training if you add a faster carbon wheelset in the future.

Who Should Buy the Tarmac SL9 Expert?

Choose the Specialized Tarmac SL9 Expert Ultegra Di2 if you want a lighter, more polished race bike from day one. It is the stronger option for competitive riders, fast climbers and cyclists who would otherwise upgrade the Comp’s wheels almost immediately.

The Expert also sits neatly below the much more expensive S-Level and S-Works builds, offering a premium specification without taking the price into five figures.

Pros and Cons

Our Verdict

At £3,999, the Specialized Tarmac SL9 Comp 105 Di2 is the standout value option. It opens the door to the SL9 platform, electronic shifting and genuine race-bike performance for roughly one-third of the original S-Works launch price.

The Tarmac SL9 Expert Ultegra Di2 is still a compelling upgrade. Its carbon wheels, lower weight and Ultegra Di2 equipment create a more complete package, especially for cyclists who do not want to budget for upgrades later.

For most riders, we would choose the Comp and consider a wheel upgrade when funds allow. For racers and performance-focused cyclists who want the stronger specification immediately, the Expert is likely to justify its premium.
