Cross. Functional.

A supremely versatile bike, the CAADX cyclocross bikes demonstrate their racing heritage with CAAD10 and SuperX inspired tube shapes, SAVE stays and race-bred geometry while rack and fender mounts and a slightly more upright position expand its usability.


  • Race on Sunday, commute on Monday. Race performance meets functional versatility.
  • Light, stiff and comfortable - Cannondale’s aluminum expertise at work.
  • Precise and stable handling, with a comfortable riding position thanks to its Relaxed Race geometry.
  • Equipped with disc brakes on some models for all-weather power and control.

Rider Profile

With its mix of high performance and durability, CAADX is perfect for cyclocross racers, fast commuters, winter training, or general rough-road riding.


  • Relaxed Race Geometry
    The CAADX has a slightly taller head tube and slightly slacker head tube angle than the SuperX, providing a more upright position and stable handling.
  • SAVE Stays
    The flattened shape and refined butting of the stays offer significant vertical compliance for comfort and control over rough surfaces, while remaining laterally rigid for solid power transfer and confident handling.
  • Smooth Welds
    A true smooth weld, rather than the sand, putty, and paint “smooth welds” of our competition. Cannondale’s trademark double-pass smooth weld technology eliminates the stress-risers and weak points found on traditionally-welded frames, enabling us to build lighter, stronger frames.
  • Taper-Butted Tubes
    Like the legendary CAAD frames of the past, the CAADX features 6061 aluminum which has been taper-butted and heat-treated to a T6 hardness. The smooth transitions provided by taper-butting eliminate the internal stress risers of traditionally-butted frames, again allowing a lighter, stronger frame.
  • Full Rear Rack/Fender Mount and Front Fender Mounts
    Rack and fender compatibilty makes the CAADX ready for duty as a fast commuter or winter training rig.
  • Disk brake equipped
    The top model comes with disk brakes for all-weather power and control.

        Comments about cannondale CAADX Disc 6 Tiagra: only complaint is that the Engineers decided to route the rear disc brake cable along the top side of the top tube, instead of along the underside of the tube. It takes away a bit of the beauty of the bike and the occassional perch. On a positive note, it's not bare wires running across the tube with little rubber grommets protecting the paint and graphic. This bike was a long over due gift to myself to encourage my 62 year old body to get back into shape. I give it 4.5 stars.

              Comments about cannondale CAADX Disc 6 Tiagra:

              When I was looking at this bike I noticed very few review online and it was difficult to decide whether to go for it based on my own judgement. I thought this might help someone else. For reference, I am an experienced road rider and have put up 1300 kms on this bike.
              I thought I was buying a bike that would be adequate as a winter road trainer. I was not expecting much more. I would put on full mudguards and get out in all weathers and put up with it being slow and that the tiagra groupset would do its job in an adequate but nothing special manner and the wheels and tyres would be lethargic and dragging.
              First impressions were that Cannondale, after all these years, are still that little bit ahead when it comes to aluminium design and manufacture. Welds are all but invisible. Paintwork is pure class. Small touches like the screw secured bar ends and enclosed top routed cables confirm that someone who actually cares about real world cycling thought out this package. I changed the saddle for one of my own and stuck on the mudguards.
              Rolling out for the first time I was very pleasantly surprised by the Tiagra group – silent slick changes front and back (the front probably aided by the close tooth difference in chain rings) I have both Japanese and Italian higher end groupsets and didn't miss anything with the Tiagra. Next impression was that the tyres soak up the entire road buzz and make for a very comfortable ride.
              Approaching a local challenging hill I was thinking I'd be spinning and sitting as I doubted this bike would lend itself to uphill effort. Wrong again. For one, I did not miss my 34 – the 36 was perfect. Secondly, when I stood on the pedals the bike responded very nicely. How or why I have no idea as the experts tell us the wheels are heavy for climbing and that these tyres are not ideal for uphill roads.
              Over the brow of the hill and into the descent on wet and greasy roads the tyres had lots of grip and the cornering put a smile on my face. Geometry of the frameset is spot on for what it is targeted at .I'd be happy to spend an all day Sportive on it this bike but it is in no way too relaxed . Point into a corner and the bike does what it needs to do without any fuss. I had never used disc brakes prior to this and had forgot that I had read they required bedding in. On a difficult off camber greasy left bend I went in quicker than I ever would have liked and had to lean hard and pray. No bother at all.
              Since that first ride the brakes bedded in and do their job nicely. I am very sure they can be bettered but on a bike at this price point they do their job to my satisfaction. Adjustment and set-up are fiddly but very possible with patience. I have not done any serious off road, just a couple of fireroads and trails where everything functioned well and lent to an enjoyable experience. I would point out that if you were a serious cyclo cross rider then the long headtube and round toptube need consideration.
              One more thing regarding this bike's performance on the road. Although I have been riding bikes seriously for best part of 40 years I am not immune to " new bike enthusiasm." So I checked my gps based diaries to compare my averages on this bike versus a high-end road bike equipped with race wheels, tyres and high-end group.
              There is nothing in it. Seriously. And within my riding group I maintain my usual place alongside lads on much lighter and skinny-wheeled bikes
              Well, that's it; I am very satisfied with my experience!
