2021 Sirrus X 2.0

Sirrus X is your ticket to riding more, and to places you never imagined possible. It's a comfortable, capable, "let's do stuff" kind of bike that will inspire you to ride more than you ever have before. With bigger, confidence inspiring tires, a slightly more upright riding position, a super intuitive one-by drivetrain, and plenty of mounts for racks and fenders —it's more than just a solid partner on pavement. Sirrus X is a dialed option when it's time to hit some gravel. We've also equipped every Sirrus X with next-level comfort from our scientifically tested and ergonomically engineered Shared Platform Body Geometry saddle, handgrips, and pedals.

A great bike with thousands of KM to prove it!

I purchased my Sirrus X 2.0 in Dec 2020 and have never looked back. I cycle heavily (over 6,600km covered between Dec '20 and Nov '22). Whether on-road or off-road, I haven't had any issues. I clean it often, including the chain and cassette, but it has had full services along the way. Mudguards were installed, however, they are not an easy clip-and-play...they took hours to put on! Highly recommend the bike for daily commuting and longer rides.

Awesome platform

After riding a mountain bike for the wrong application (city/gravel trails), this is like getting a super car. It is incredibly lightweight, agile, and quick. I feel like i can really push myself on this bike without getting fatigued from over pedaling, like you would on a mountain bike. The hydraulic brakes are super responsive, and noiseless after a proper bed in. My favorite feature are the hybrid tires. They have little rolling resistance on pavement, and the bite you need on gravel. I would recommend this bike to anyone looking to commute to work, or just something that isn't quite road/mountain but more of an in between. If only cities would accommodate those of us that want to bike more, as most places have limited dedicated areas. Hopefully that will change one day.

Great bike, for both off-road

Great bike, for both off-road and road. Gears shift fairly smooth. All black frame looks really good.

Beautiful looking bike

The bike is aesthetically correct and the colour is an unusual dusty turquoise. It is comfortable and at first it was much faster. Unfortunately it has suffered the same chain issues and that has damages the chain guard and chipped the paintwork. Bike still looks great but it will cost me to repair or replace the faulty parts. Disc brakes are awesome though.

Chain and gears update

I wrote a review about how the chain and gears are useless on this otherwise great bike. When I took it back to ship the first time, they just adjusted the derailleur, which only helped for a couple of days. I took it back a second time... they found the real problem, which was the rear wheel cogs not being properly aligned and tightened... they fixed this and the bike has been a dream since... doesn't slip gears, chain hasn't come off.... so if you experience this problem with the bike I recommend getting your retailer to look specifically at this.

Reliable bike

I’ve had this bike for a yr now and only cover @ 50miles a wk on it – road & baths. Use it for work and it’s never let me down. Lovely ride, smooth gears and braking v.good. The only issues I’ve had are the peddles, one sheered off while on the bike!! And the bearings around the peddles are creaking so need to change them. Purchased from Bristol, good service. Other than that, I love the bike as do my sons!!

Chain issue and gear issue

When I first got the bike, the chain would fall off constantly and I would have problems changing the gear. I had to bring it back to the shop several times before the issue was resolved. Now, I don't have the chain problem, however, the gears don't change as smooth as I would want it to be. Sometimes it is stuck in one gear before it changes.

Love this bike! (After mods)

So I purchased my Sirrus X 2.0 in June of 2020, and I’ve been riding it every other day since! Comfortable ride position, great handling, lightweight hybrid with bigger tires for the trails, strong disc brakes, and clean styling. Yes, I experienced the chain coming off the front as you accelerated and it was frustrating. But the great service crew at Roseville Cyclery were able to obtain a rear derailleur with a clutch from Specialized that fixed the problem. I can ride it anywhere now and the chain stays on. This bike can’t be a better value at its price point. Most of all, it’s just fun to ride!
