Summary of Reviews

We have read all expert and user reviews on the Ridley Fenix. In summary, this is what cyclists think.

15 reasons to buy

  • It was widely agreed among experts, that the Fenix was an all-rounder, suited to both sprints and endurance, for amateurs as well as pros.
  • The frame was assessed as being responsive, well-handling and solid. It was said to be ‘cobble-friendly’ and both racy and relaxed.
  • This bike was considered to be very stiff, a factor increased in the chainstays by a wide bottom bracket. Compliance for endurance was added to by an arched top-tube and carbon / resin construction.
  • The drivetrain was portrayed as being faultless and efficient, on the Ultegra Mix.
  • On the SL 10, Zipp 202 Firecrest wheels needed no upgrading. They were regarded as aerodynamic but not too deep or heavy against winds. Users said the DT Swiss E1800s on the Ultegra Disc were sturdy, stiff and bombproof.
  • The Fenix’s ride is depicted as being smooth, comfortable and stable at high speeds. Its deemed an excellent climber, comfortable all-day and good on slight gravel.
  • On the SLX Disc, Campagnolo Potenza Brakes offered great modulation. On the Ultegra, users said discs were quiet and easy to modulate. Rim brakes on the SL Ultegra were rated highly.
  • Most users received their Fenix partially assembled and said any remaining setup was simple.
  • 30mm tire-clearances were appreciated. Continental GP4000s came pinned to the SL10 and received praise. On the 105, users said stock tires need no replacement.
  • The Fenix’s industrial design lended it a ‘gorgeous’ appearance and attractive shape.
  • Ridley offers customers a custom paint program on its own site. Stock colorways, such as the all-black found on the SLX, were divisive. Some found it mean and rad. On the SLX Disc LE AXS 12, an iridescing red/black scheme dazzled.
  • Experts said the full Ultegra was great value on the SL. The SL 10 was dubbed ‘competitive. In general, the Fenix was viewed as decently priced for its versatility and full carbon frame.
  • Weight on the SL Ultegra at 17.85 lb and the SL 10 at 16lb, was reckoned to be ‘respectable’. On the SL Disc, 18.69lb was ‘decent’. The SLX Disc, at 17.3lbs, trimmed 300gm off standard models by using higher modulus carbon.
  • Steering was seen as snappy and responsive but not twitchy. Others saw the bike’s neutrality as superb. It was felt to be confident and secure, feeling planted through corners.
  • On Ultegra models, the 6800 groupset was praised. The 52/35, 11-28 gearing offered a generous range. Campagnolo Potenza on the SLX Disc delivered great performance. Users said 105 kit was easy to adjust and SRAM AXS groupsets were amazing.

8 reasons not to buy

  • One expert felt that caliper brakes on the Ultegra Mix reacted with excess flex.
  • An expert judged the SL Disc as perhaps not representing the best value.
  • Contact Points (including saddles and bar-tape) on the SL and SLX Disc models were evaluated as being too harsh for longer endurance rides.
  • The SL 10 was deemed to not be the lightest of its class. A reviewer of the Classic Ultegra noted that it wasn’t as light as a pure race superbike.
  • The SLX’s stock black-on-black colorway received polarising reviews.
  • In contrast to most other reviews, one expert described the ride on the SLX as slightly rough and not so comfortable on long rides. The ride on the SL was viewed as ‘somewhat firm’.
  • Wheels on the Ultegra Disc were represented as not being ‘super-light’. On the Ultegra Mix, a disappointed expert recommended fixing tires no wider than 25mm to the narrow rims. Forza RC31 Wheels cought crosswinds and seemed slow on climbs.
  • A single user complained of the amount of assembly required for their Fenix A Tiagra.

Bottom line

There is a dizzying number of model specs for the Fenix; eighteen in carbon and six in aluminum. With a majority of buyers opting for carbon, they report on a road-bike that somehow felt both relaxed and aggressive, professional as well as approachable to amateurs. Almost all experts and users felt this bike was equally suited to getting up out of the seat on gung-ho sprints – as it was to long-haul endurance. It’s not the cheapest bike but it was rarely seen as overpriced, due to the high quality of componentry represented in all the various Fenix configurations.

Ridley Fenix SL 10

While not featherweight, it’s light enough to take to the high mountains, conquer the cobbles and is even capable of delivering André Greipel to the line first in a bunch sprint.

Ridley Fenix C Ultegra Mix Review

My overriding impression of the Fenix C is of a good frameset with a great fit that can be as racy or as relaxed as you like. But so much of that is compromised by those narrow rims…

… The Fenix is not a pure comfort bike – it also has a race-oriented geometry. You can easily complete long distances as well as intensive units. The handling allows for both and makes the Fenix an all-rounder.

RBA Test: Ridley Fenix

It’s stiff enough to keep you competitive on the weekend group ride or at the occasional criterium, but it’s compliant enough to not beat you up even after a long day in the saddle.

We were able to convince ourselves of the high driving stability of the carbon frame on a test round. And also, the Fenix is nice to look at.
