Expand your horizons.

The peloton is notoriously adverse to change, so when disc brakes start to voluntarily appear in the top tiers of European racing, you know that the technology isn't just a marketing gimmick. As such, Ridley's 2017 Fenix SL Disc Ultegra Complete Bike brings all the Flanders-worthy elements we loved in the rim brake version and ups the braking modulation ante with Shimano's Ultegra hydraulic braking system. Add in our own custom colorway, the legendarily trustworthy Ultegra mechanical drivetrain, and stiff, responsive thru axles, and you have a race-ready ride that's as functional as it is prepared for the bike industry's future.

While this Fenix is more than capable in Flandrian sprint finishes and animated road race tactics, its combination of powerful disc brakes and artful layup of vibration devouring unidirectional carbon fibers expand its capabilities beyond buttery smooth pavement into roads (and paths) less traveled. In comparison to the super-stiff featherweight frames in Ridley's line that use up to 60-ton moduli, the Fenix SL utilizes a blend of 30-ton and 24-ton carbon to strike a balance between road-smoothing compliance, rigid efficiency, and race-worthy weight. Poorly graded gravel, cobbles, and other road hazards that would otherwise feel like jarring punches on a 60-ton carbon take on all the disagreeability of crosswalk paint—though the stiff, tapered head tube does provide responsive steering to dodge the unrideable obstacles.

Compared to the original Fenix, the Fenix Disc also has a slightly bigger wheelbase, measuring 2mm longer for a size medium. While this difference is more pronounced in the smallest sizes, even the bigger frames benefit from a more stable footprint for loose gravel and packed dirt roads. The adventure-minded cyclist will also appreciate the Disc model's increased tire clearance, allowing bigger tires for maximum plushness and reliability on everything from summer chipseal and sun-soaked logging roads to loose limestone gravel.

  • An endurance bike with expanded, all-terrain capabilities
  • Endurance geometry blends comfort with responsiveness
  • Carbon construction balances stiffness and compliance
  • Beefy bottom bracket shell transfers power efficiently
  • Responsive tapered head tube tracks confidently
  • Hydraulic disc brakes increase stopping power
  • Ultegra drivetrain delivers precise, reliable gear shifts
  • Special colorway specific to Competitive Cyclist

wow, just, wow!

  • Familiarity: I've used it once or twice and have initial impressions

Took my inagural ride today and I must say Im impressed.

First let me say that backcountry / competitive cyclist? did a great job. Made it to my house in Oregon from Utah in 3 business days and arrived very well packaged. All I had to do was install the wheels and handle bars. Came with all the Ridley documents and a thorough assembly checklist from competitive cyclist. When I say checklist I mean a 42 point list of all the things you would expect from a proper, professional, build. everything is perfectly aligned, and properly torqued. Its the kind of thing that's very reassuring to see especially when buying a bike online.
Speaking of buying online, Ridleys run stretched out! They have LONG TOP TUBES. Believe the reviews when they say you might want to size down. This Fenix is replacing my Ridley Orion so I already had experience with the brand. I'm 5ft 6.75 inches on a good day with a 31 inch inseam. Most brands say I'm a small or even medium frame. Ridley its definitely extra small.
Now the bike. For 2600 bucks you're getting full ultegra kit, shimano hydros, and a bad a** frame. This is a lot of bicycle for the cash, even with the kinda clunky stock wheelset. Lets be honest if you're a wanna be racer, weight weenie like me... you're probably going to replace the wheels anyway. For the majority of folks these wheels are fine. Mine are DT Swiss rims with Formula hubs, they weight about 1850g. The bike is great just the way it is, but with a hand spun 1500g set o' hoops this thing would be like having a time traveling, flying, DeLorean.
Clearly from reading the other reviews there are slight variations on what's being shipped out. Mine came stock with 25mm contis, I'll probably switch to 28s. Mine is apparently the climbing version because it came with a 10-32 cassette; nice. Spinning is winning!
How does it ride? this is a stiff, comfortable bike. Its more comfortable than my orion due to the compliant rear end (seat stay configuration), and stiffer than my orion due to the carbon layup, thru axles, and bottom bracket. It's very comfortable on a medium length ride (50 miles) but still jumps when you put the hammer down. Would a Specialized Roubaix or Trek be more comfortable with their head set spring, and iso decoupler thingy, maybe. But you'd be ridding a specialized, or trek, along with everyone else, and their mom. The modern tapered head tube makes the bike feel nimble but not twitchy. It enters a turn with a little bit of an effort but once in and copping a lean it goes through the apex like its on rails. With this handling and excellent braking descending is a hoot.
This is just a great bike. Made by a Belgian company with racing pedigree. Sold by some folks who clearly know what they are doing.
It was a little over priced for the competition when it first came out, but at this price do yourself a favor and buy one.
Any one interested in a well loved Orion? :-)

Very convincing and a great review! Thanks!

Disc Road

  • Familiarity: I've put it through the wringer

I love that it comes stock with a 28c tire. I experimented with 25c tires years ago and swore I would never go back to 23c, I wouldn't ride them if they were free. The 28c tire as a stock tire, with plenty of clearance really sends the message that this bike is ready to incorporate a dirt road or two into your loop, and frankly I like that option. This is far from a gravel bike though but fits nicely into the endurance road category. I feel like Ridley is ahead of the game here, through axle disc, flat mount brakes, and 28c tires stock, I am willing to bet it will be another year or two before some of the other bikes in this category are coming with this setup, but it will happen. I would buy this bike all over again too.
Ridley's tend to run long, so pay close attention to the numbers. I typically ride a 54cm frame from the big red S and felt right at home on an XS

Riley Fenix SL Disc

    I'm new to biking. I did some research and bought this bike. It's sweet to ride and the friends I ride with say it makes me look like I've been riding for years. I have disc brakes on my mountain bike and wanted them on a road bike. Excellent.

    great all around roadie

    • Familiarity: I've put it through the wringer

    The Fenix replaced one of my favorite bikes of all time, the Ridley Excaliber. I was a little worried it wouldn't live up to the predecessor but I was really pleased when I got my new Fenix. It's really a comfortable bike and probably ideal for 80% of road riders out there. I have it set up with ultegra and been very impressed with what a great bike it turned out to be especially considering the cost. It's a competitive bike but if you a really serious racer I think you'll find the bottom bracket a little soft/flexy when in a high speed sprint and that's really the only downfall in my opinion. Feel free to contact me with questions on builds or specifics on the frame. they run pretty big and at 5'7" I ride an XS and can actually ride an XXS if I want to get really aggressive


      This is one of my favorite bikes of the year so far - Hard to beat this build and price.
      Great bike for endurance rides or the 60-minute morning ride. The High Modulus carbon keeps the ride smooth and the overall weight low (18lbs). Easy to lighten the bike up over time if weight is a concern…cassette, carbon bits, wheels etc.
      Gearing is great on the bike. Comes with a sub-compact 52/36 and a 28T cassette on the rear. This gearing will allow you to tackle just about anything.
      You may be wondering why you are not seeing this color frame anywhere else. Competitive Cyclist has worked with Ridley to get this custom paint job, so you won’t be seeing this rolling around in the local shop. If you want to run this tubeless you will have to swap tires and get a tubeless conversion kit (Item # EAS001N) – happy to do this for you just give me a call or shoot me an email.
      Please feel free to reach out if you have any questions or if you are interested in it.
      Sizing: I’m 5-10” Saddle Height 71.5cm, I went with a Med for more of a upright riding position.
