Specialized launch all new Sirrus X 'grammuter' bike for 2020, with wider tyres, new geometry and 1x gearing

The new off-road friendly version of this classic commuter from the big S is shorter and taller, and is designed 'to take the Sirrus platform to places it has never been before'

Specialized have launched an all new version of their popular Sirrus hybrid/commuter bike, the Sirrus X. This one is more than just a city dweller, with wider tyres, 1x gearing and disc brakes on all models.

Like the standard Sirrus, the Sirrus X is unisex: "specifically designed as a shared design for Fitness riders", say Specialized. Rather than just taking the Sirrus, sticking some slightly bigger tyres on and changed the name, the Sirrus X also has a slightly different geometry, with a reach that is 10mm shorter and 15mm of extra stack. 

Sirrus X 2.0 and 3.0 have 42mm tyres, while the higher end 4.0 and 5.0 drop down to 38mm because the addition of Future Shock suspension negates the need for very wide tyres to add comfort; the top-end Sirrus 5.0 is the only model that is set up for tubeless tyres.

All Sirrus X bikes have a single chainring for simplicity, and include eyelets at the dropouts and fork for mudguard mounting. Mounts for racks differ depending on the model. 

There are also new standard Sirrus models for 2020, starting with the Sirrus 1.0 with an alloy frame and rim brakes, and going all the way up to the £1,999 Sirrus 6.0 with a carbon frame and fork, Future Shock and Shimano 105 shifting - all have either triple or 2x chainring set-ups as opposed to 1x on the Sirrus X models. 

Models and prices of all Sirrus and Sirrus X bikes coming into the UK are as follows: ​

Sirrus X 5.0: £1,599
Sirrus X 4.0: £999
Sirrus X 3.0: £699

More details and all your buying options are now on the Specialized website. Does the dawn of the Sirrus X mean gravel and commuter bikes are now crossing over? We even reckon we've coined a new term to accurately describe it (see headline). Let us know what you think in the comments of course... 

After cobbling together a few hundred quid during his student days off the back of a hard winter selling hats (long story), Jack bought his first road bike at the age of 20 and has been hooked ever since. He was Staff Writer at 220 Triathlon magazine for two years before joining road.cc in 2017, and reports on all things tech as well as editing the road.cc live blog. He is also the news editor of our electric-powered sister site eBikeTips. Jack's preferred events are time trials, sportives, triathlons and pogo sticking (the latter being another long story), and on Sunday afternoons he can often be found on an M5 service station indulging in his favourite post-race meal of 20 chicken nuggets, a sausage roll, caramel shortbread and a large strawberry milkshake.
