Build your own lion of Flanders.

The Excalibur is Ridley's best-selling race frame for good reason. Some of it is self-evident: At 1100 grams, it's second only to the Helium in Ridley's spectrum of lightness. This is because the Helium uses higher grade carbon fiber (and therefore less of it) netting a lower weight, while the Excalibur relies on 24 ton material with 30 ton reinforcements in the high stress areas of the frame. This is where the cost savings are derived, but don't think that you'll sacrifice stiffness or performance one bit. And, like the Helium, the Excalibur utilizes full carbon dropouts and head tube to reduce weight even further.

Unlike the triangulated "Sharp Edge Design" you find on the Damocles, or the super-aero tubes of the Noah, the Excalibur is built with oversized round tubes. Here's a good tip: If you're interested in assessing the likely torsional stiffness of a frame without eve riding it, inspect the girth of its tubing and junctures -- larger diameter tubes resist deflection better than small. Then take a long look at the headtube/down tube juncture and the down tube/BB juncture of the Excalibur and utter a big "WOW." You'll verify this stiffness under power on the first ride as the Excalibur leaps with every pedal stroke.

While you might look at the Excalibur and think it's a mere kermesse bike -- the sort of "grip it and rip it" rocketship suited for little more than the warp speed circuit races so popular throughout Ridley's homeland of Belgium, think again. It was the team bike of the UCI Continental Pro Team Unibet. Unibet riders cracked the top-20 in 6+ hour epics such as the Tour of Flanders and Paris-Roubaix, as well as a host of other rough-and-tumble spring classics on the worst roads of Belgium and northern France. Team Unibet knew the secret of the Excalibur: Its oversized tubing gives it top fuel racer-like acceleration and resistance to flex, but it won't brutalize you when you head out the door for a 5-hour cruise in your 53x19.

You'll be hard-pressed to find another carbon bike in the Excalibur's price class built with such care (both structural and aesthetic), with similar lightness, durability, smoothness and with anything even closely resembling its pro pedigree. It's a thoroughbred that has many of the markings of framesets priced well above it.

The Ridley Excalibur is available in White/black and comes in five sizes from X-Small to X-Large. Given its compact geometry, we strongly suggest that you focus on the effective top tube length as you make a determination of the proper size. The frame comes with a painted-to-match Ridley 4ZA Excalibur monocoque full carbon fiber fork and a proprietary FSA integrated headset. It requires a 31.6mm seatpost, an English bottom bracket, and a 34.9mm front derailleur.

  • Curved, wafer-thin seat stays soften up rough cobblestones or gravel fire roads on your 'epic' rides
  • Carbon fiber dropouts and steerer tube shave excess weight

I rented an Excalibur for a 200K...

and I really liked it. My other bike is a Cervelo R3, which I also like very much, but the ride is so harsh on the rough Sonoma County, CA roads where I ride. Anyway, I've been looking for a bike that is stiff, fast on the flats and rollers, climbs well, like my R3, but unlike the Cervelo, also with a much smoother ride on rough road. There weren't any major climbs on the 200K, so I didn't get to test it well that way, but for the rollers and flats I was on, as well as plenty of rough spots, the Excalibur matched the R3 in terms of that feeling of speed and lurching forward under power, but was vastly superior to the R3 in how well it soaked up road shock. It was hard to believe it could have that stiffness and still ride so smooth! I found myself much less concerned about taking lines in the road to avoid patches that would give quite a set of little jolts on my other bike. The handling on descents was also very impressive -- very easy to maneuver but very stable and super easy to ride with no hands on the bars. It's hard to believe that Ridley discontinued this bike, but I'm grateful I managed to get one from you guys -- a great build at a fantastic price. I can't wait to take delivery and get that baby out on the road!

Unanswered Question

Is the 1100 grams weight for frame only,...

Is the 1100 grams weight for frame only, or is it the weight of the frame and fork: this is with reference to the XS. Thank you

The zoomed in photos of various frame...

The zoomed in photos of various frame features look like the Lotto-Belisol team red/black colors, but the photo of the full frame is not the Lotto-Belisol team colors. Can you confirm whether the red/black XS is the Lotto-Belisol colors?


Responded on

The red/black XS would be the same as the main photo. The Lotto color has sold out.

Corners like it's on rails.

  • Familiarity: I've put it through the wringer

I have the Excalibur built up with SRAM Force and some old Ksyrium SL wheels. I've ridden it in criteriums, road races, time trials, and local fun rides including the RAMROD, which is a 150 mile ride with over 10,000 feet of climbing. It's comfortable all day in the saddle, climbs efficiently, and corners smoothly and predictably. This is a great bike for a guy like me who 1) loves to ride and 2) occasionally rides (marginally) competitively.

Which year is this one? Does not look like the 2012 model.

It is the 2012 model - I purchased it at the beginning of 2013.
