"...the redesigned Sirius [R853] delivers in spades."
"The sorted handling, impeccable ride quality and 130mm fork compatibility mean it's all the trail bike you're ever likely to need. Light, lively, versatile and a whole bunch of fun, it's also exceedingly good value."

"Strong enough for 130mm forks yet lively enough for trail duties, this is a consummate all-rounder."
What Mountain Bike Magazine 09/10 - Read the Bikeradar review

To quote What Mountain Bike's technical editor Steve Worland: "Singletrack handling is superb...the ride is lively and well balanced."
"It's our clear top value choice."

"The word 'neutral' could almost have been coined to describe this bike's ride character. Neither nervy or ponderous, it feels right as soon as you climb aboard."

"...the layout delivered a beautifully sprightly ride. This isn't a hang-back-and-hope bike - the Sirius wants to actually be ridden, and responds to getting over the front and doing some work...everyone who had a go came back grinning." - Read the full review

"The ride responses of the frame are superb. It has a taught but resilient feel, skipping without fuss across the bumpy stuff and appearing to have a real spring in it's rhythm on climbs and in sprints. [The Sirius Ti] felt spot on for fast cross-county use but the long-fork geometry allows a relatively carefree approach if the going gets really tough."

"A hard-riding hardtail at the weight of an XC race bike for a good price." - Full review at Bikeradar

"The combination of stout feel, agile geometry and plenty of clearance both above and below the frame makes for a bike that loves technical trails, up and down." - Read the full review

"Where carbon meets steel, magic is made."

"It climbs well, it deals with fast rocky drops as well as any hardtail we've tested and it inspires on singletrack."
"This is a point and pedal bike of the highest calibre.."
