The Belgium-based Lotto-Belisol World Tour Team is going for a classic, retro look in 2014 — the Belgian National lottery has been sponsoring a team in the pro peloton for 30 years, and to this end, the team's kits pay homage to sponsors and to its Belgian origins. And while retro is cool, riders want the fastest bikes available, and that means the steel frames of 30 years ago will remain a memory. Ridley is leaps and bounds ahead of 'retro' and its Noah Fast was one of the first bikes in the industry to be tested and designed around aerodynamics. 

While other companies look primarily at modifying tubing shape to determine optimal airflow, Ridley looked at every portion of the frame, from brakes to paint, and subsequently developed the ultimate World Tour race machine. And while technologies are impressive, quantifiable numbers are moreso. For example, the combined technologies of the Noah Fast offer up to 2.8km/h advantage in a sprint and up to 20 watts less power input needed to average a 40km/h (just under 25mph) breakaway. And while we can't guarantee that the podium is yours, if you make the break, the advantage certainly is.

The Ridley Noah Fast shares the same carbon fiber blends (50, 40, and 30-ton carbon fibers), geometries and proven aerodynamic features as its Lotto-Belisol team-issue iteration, including an aerodynamic down tube, internal cable routing, an aero seat tube that extends into an integrated seat mast, plus a deep rear wheel cut-out. The Noah Fast sets itself apart from the standard Noah as well as other "aerodynamic" frames, in is its use of Ridley's FAST Concept Technology . As a result, the Fast is, well, faster than the standard Noah, and of course, faster than the competitors. One of the most notable developments are the F-Brakes. These are not unlike the linear-pull brakes seen on TT bikes, but with significantly greater power modulation. Both calipers hide completely out of the wind behind the slotted 4ZA F-Splitfork and rear seatstays. In addition to the aerodynamic benefits of these hidden brakes, the lack of a brake caliper actually helps further reduce the frame weight and adjustment complications, due to the simple cable-actuated lever near the handlebars.

The Fast also utilizes Ridley's F-Fork, This slotted front fork focuses on one specific issue of bicycle aerodynamics: According to Ridley, your wheels produce eight times more drag where they pass through your fork and seatstays, due to the turbulence of the colliding air masses there. The Noah is built to minimize this drag with its use of long, slotted airfoils that are built into both the fork legs and the seatstays. These airfoils redirect oncoming air away from the turbulent areas near the wheels and reduce drag by 8.2 percent.  The oversized head tube provides additional front end stiffness so you'll feel comfortable cranking on it in the heat of the final 200 meters.

Now for most frame companies, these technologies are more than adequate. But Ridley doesn't stop at tubing, brakes, and fork. Ridley used oil mapping in the wind tunnel to isolate spots of turbulent airflow. And where structural limitations kept Ridley from re-sculpting the frame, it applied a textured surface treatment for boundary layer control. Ridley calls it "F-Surface," also affectionately referred to as "aero paint." These thin strips of texture are amazing -- they purposely trigger a known amount of turbulence that re-energizes lost boundary layers, ultimately re-establishing laminar flow, and minimizing drag. In other words, they carefully create an airflow mess in order to make an unprecedented cleanliness. Airflow control is why you see vortex generators on aircraft wings, and why you see dimples on golf balls. And it's exactly what Ridley does with its F-Surface paint.

The Ridley Noah Fast Road Bike Frame - 2014 is available in the sizes X-Small, Small, Medium, Large, and X-Large and in the color Black/white. Given its semi-compact geometry, we strongly suggest that you focus on the effective top tube length as you make a determination of the proper size. And whether you choose to build your Noah Fast up with a SRAM, Shimano, or Campagnolo groupset, Ridley has assured us that the F-brakes are fully compatible with all three — mechanical and electronic. The Noah Fast requires a PressFit 30-compatible bottom bracket and a braze-on front derailleur. It includes a 120 gram seat clamp assembly that allows an 18mm range in saddle height and comes with 1mm micro-spacers for small adjustments. Ridley also offers an aftermarket clamp that provides 40mm of height adjustment.

Great All Around Bike

  • Familiarity: I've put it through the wringer

I've been using the Noah Fast for a few months on a windy 17 mile beyond category climb in SoCal and I can't imagine a better bike to do this with. It's light at 15.5 lbs and can handle gusty descents markedly better than any other bike I've ridden. My average downhill speed has increased by more than 5 mph and its handling is accurate and predictable. With the current design trends of spindly rear stays and the awkward looking lowered seat stay attach points, this bike may well be the best looking of its generation and something to hold on to. What else can you ask for?

Would a medium fit a 6'1" rider?

I'm 6'0" and the fit was perfect. I cut almost 2" from the seat tube.

Is the weight listed correct? You list the frame at 2.27 kg, but on other websites the weight of the noah fast frame is listed at 1.1 kg? Do different models of the bike have different weights?

My build with sram red 22 and aero carbon wheel set with power tap power meter was 15.5 lbs.

Is the small size a good fit for a 5'6" rider?

It would be a stretch, but yes I think it will work. Ridley's fit quite large. Give me a call or email at extension 4769 or and I can go through specifics with you and options on how this set up would work.

Will the medium frame fit a 6'3" rider? My current bike measures 33" from crank center to saddle top.

I would suggest a large size in this frame.

FAST is a fitting title

  • Familiarity: I've used it several times

If your serious about racing/performance it's worth the extra money over the Noah. It just gives that little bit extra into an already superb frame with a slightly higher carbon grade and more profiled brake set up.

I have owned/raced on several ridley bikes including the helium and Noah. The Noah is surprisingly light for what would be considered the heavier frame in Ridley's lineup. I wouldn't hesitate to ride it as an all around race bike but it shines most on the flats into the wind on a solo break. Excellent aerodynamics and super stiff bottom bracket make it handle superb in any situation and no loss of power in your pedal stroke, you get everything out of it you put into it. An excellent choice if you have one bike for training/racing, and doing tri's or TT's as the aero properties give you full advantage of all that has to offer but geometry can be ridden everyday. clip on some aero extensions and your good to fly.

Sizing can be tricky on Ridley bikes as they do tend to run a little bigger than most so free to contact me here at with questions on the Noah, frame in general or with sizing questions.

How are brakes adjusted when switching wheels of differing rim widths? EG - is there a "quick release" or some type of adjustment lever?

There is a quick release wich opens the brakes. The fork is developed for 700C race wheels with a build in width of 100 mm, quick release system with a maximum diameter of 9 mm Brake - wheel clearance. The F-Brake can accommodate wheels with a maximum brake surface width of 23 mm. Fork - wheel clearance. The fork can accommodate wheels with a maximum rim width of 30 mm. all that according to bicycle manual.
