Ridley Helium SL Road Bike Frameset - 2016 $3,499.00
The 2016 Ridley Helium SL Road Bike Frameset is a featherweight among giants, ready to fly up the mountains like a stage-hunting falcon. While some may express concerns about an ultralight frameset's ability to transfer power and handle descents, rest assured that this frame boasts a near-unicorn mix of minimal weight, stiff power transfer, and the ability to rail corners and bomb descents with the best. This rightly well-loved frameset is back for 2016 with classically inspired colorways to light up any ride.
Aesthetics aside, though, the Helium's main job is dropping grams. A medium SL clocks in at a claimed featherweight of 1,110g for the frame and fork, which is a staggering 800g lighter than a similarly-sized Noah FAST aerodynamic machine. This was achieved with smaller, less aerodynamic tube shaping and a strategic arrangement of 60, 40, and 30 ton high-modulus carbon fiber to create a frame that efficiently transfers power.
Ridley also incorporates an ultra-strong nano-resin into the frame's lay-up, which allows the Belgian manufacturer to use less carbon, decreasing overall weight while boosting durability and stiffness. To further reduce weight, Ridley constructs the front triangle of the SL with a monocoque design. This means that the entire front triangle (head tube, down tube, seat tube, and bottom bracket lug) is made in one piece, saving weight by eliminating the extra material needed to reinforce frame junctions in multi-part triangles.
The SL features rounded tubing emanating from the seat tube juncture, which slowly becomes box-shaped as it approaches the head tube and bottom bracket junctures. As Ridley puts it, this system creates a clean transition from stiffness to comfort. Supporting this ideology, the rear triangle has been designed with a blend of the two shapes. The asymmetric, flat chainstays provide a stiff platform for power transfer to the rear wheel, while the ultra-thin seatstays create a vertically compliant ride quality without sacrificing rigidity.
Although the Helium SL falls solidly in the lightweight climber category, Ridley claims that it's stiffer than the original Helium. Its testing shows that the SL is 8% stiffer at the bottom bracket, 4% stiffer at the head tube, with a 20% increased side stiffness in the fork — all of which is a very mathematical way of saying the SL transfers power more efficiently than the Helium for a snappy ride. To cap things off, Ridley finishes the Helium SL with internal cable routing for clean lines and compatibility with both mechanical and electronic shifting systems.

Hi guys! Ready to buy this frame. Great deal. Need some help on measurements. For the XS size frame, what is the fork rake/offset and do you know the front-center (FC) measurement?
Curious about the XS vs S. I'm 1.71 meters (5'7.5") tall. I'm all leg, very small torso. Based on effective top tube length, I'd be on an XS, but I'm concerned about seat post length. Are there limits I should be aware of? Thanks!!
Ridley Helium SL Review
- Familiarity: I've used it several times
I bought this to replace my Cervelo R3 with a creaky BB. I find Ridley appeals to me (you know, tough no nonsense Belgian approach) and was looking for a sporty bike that handles well and is lively for short rides. I bought the retro paint scheme version b/c it just looks so classic.
I am 69 inches tall and generally ride a 53/54cm or Medium frame but Ridley's are sized on a smaller side so the Small frame fits perfectly. This is a fairly traditional looking frame with double diamonds and pretty traditional geometry except for a tall 66 BB height. I though that would make the bike fall over into turns too easily but that isn't the case. Although it's made for racing, the reach is not very long so you can get a fairly upright position as well which is nice.
Mine weighs 15.8 lbs with cages and pedals which is very light for me. The finish is matte and seems less prone to scratching as with glossy finishes. In terms of performance, the initial feeling is that of stiffness and solidity. This is a racing bike and it feels best when you are cruising in the drops or accelerating/climbing out of the saddle. The frame is very stiff, I'd say only the Giant TCR is stiffer feeling, and feels very efficient. I found with Mavic Cosmic Carbone wheels, it would cause brake rub whenever I stood up to pedal. So I switched them to Novatec Jetfly's which seem to have taken care of the brake rub. So I'd recommend using a fairly stiff set of wheels since the frame doesn't seem to flex much if any at all.
Like the TCR, it has a very stable handling. You can let go of the bars and it tracks straight, bumps around turns don't seem to really upset the chassis or your line. The bike handling is neutral, no over or understeer and it leans in progressively (although your tire and wheel combo choice may make a difference) . Steering is not lighting quick, bordering on twitchy like the Cervelo R3, it's a touch more gradual but definitely not slow. Once it's set into a turn it corners like it's on rails giving you a secure sense as you descend. With its secure handling, you can get a false sense that you are going slow as there is no drama at higher speeds as with some more twitchy bikes.
As for comfort, the geometry is good, you are not leaned over like the Giant TCR with it's long reach, but the bike is too stiff. I am running Conti GP 4000 S II 25 mm tires (which tend to be wider than their stated size ) with about 80/90 psi front and rear and the Jetfly rims which are pretty wide for maximum comfort/bump absorption. There is a small amount of space between the fork/chainstays and the tires on my set up, so you may be able to fit narrow 28mm tires or fat 25mm tires. There is no transmitted vibration but the amount of impact harshness transmitted and the bike's personality of prodding you to ride fast in the drops and standing up to hammer wears me out after a couple of hours in the saddle. But I have more comfy bikes for longer or more relaxed rides. So if you thinking about doing gran fondos and centuries on this thing, this may not be a good choice, unless your route is free from road imperfections. If you are looking for a stiff, stable handling, and a lively bike for racing or for shorter spirited rides, this may be a good choice.

I've taken this bike out for a few rides now and am really impressed. Now, I had never actually ridden a Ridley before and have heard from co-workers and customers alike that have had great things to say.. but it was my chance now.
This is a fantastic deal on a great riding road frame... oh and this one weighs 1100 grams frame AND fork.
Sizing: I am 5'11 and fit perfectly for most brands stock 56cm frame. On this bike I fit a 'M' frame. Please reach out if you do have specific sizing questions.
Looks: Well you can't be cruising around the neighborhood on something ugly now can you? Luckily this bike looks the part- nice almost classic look to it- no aerodynamic camm tail hyper fin robotic carbon dragon wings here. Heck, I'd consider getting a poster made to go next to my collection consisting of Kelly Kapowski and Jonathan Taylor Thomas.
Ride: What we're all waiting for: Good. Great. Grand. Wonderful. It rides like a high quality road bike should. Super light (Helium Superlight by name) the thing rockets up the mountain. I was actually quite impressed with the descent almost more so than going up. I knew it was going to fly going up with a name like helium super light. So bombing down Guardsmans Pass (though not as fast as the Tour of Utah guys) I was stoked to see how smooth, stiff, and planted it felt.
This a great base for your dream build. So many options you can have with this as your blank canvas. Give me a ring or email if you have any specific questions on my ride impressions, build options, why Sagan should still be in the tour, sizing, etc.

Can this frame accommodate 28c tire width?
I don't think it will unless it's a very narrow 28mm tires. It fits Continental GP 4000 S II's in 25mm which is very wide, close to a 28mm Gatorskins IMO. It can catch objects and scrape teh bottom of the fork so I'd suggest putting an electric tape under the fork, just above where the front tire is to protect the pain.
