I was 28 before I made the realisation that 110mm stems provide the best balanced handling, and actually, having my bars a bit higher was still aero enough and a damned sight more comfortable.

In terms of performance, the SL-K does everything well enough, but nothing really stands out about it. Stiffness is good and should be plenty for most riders, while the weight is about average. One thing that does stand out is the fact that the bolts have remained uncorroded despite over a year's worth of use in between periods of storage in a very damp shed. This stem is made of durable 6061 T6 aluminum for an optimal ratio between weight and stiffness. The 4-way screw clamp guarantees a durable attachment for oversize handlebars. The stem is supplied with a suitably shaped top cap. Features of the FSA ACR stemAerodynamically optimized aluminium stem with fully integrated cable routing! The FSA NS ACR Road stem is part of the fully integrated cable routing system called ACR. It allows the cables and wires to be routed internally at the most important points in the steering area. Enjoy cat-like agility in the turns, and a lower centre of gravity for improved stability with quality bicycle parts from top brands like Race Face, Ritchey and Deda. There can't be any hard numbers as we're all different, so I imagine the lead up as being on the lines of: According to the brand, the Filante SLR was designed to be as aero as possible, but with similar ride characteristics and weight numbers as the Zero SLR. The frameset is disc-only and designed solely for electronic groupsets.

Upgraded components help to sharpen bike performance, and with BMX, MTB, commuter and road bike handlebar stem components all available, you can upgrade your bike stem to match your preferred cycling position.

How does it feel? Better? It’s good to do a couple of rides of decent length to see how the stem length change impacts your riding comfort.

Wilier doesn’t make specific claims about the magnitude of aero improvements over the Filante SLR’s predecessors, but the bike does take a somewhat new approach. Bike Fast Fit uses the phone's video camera to dynamically record the rider’s position to analyse a whole range of measurements, including stem length as part of the frame reach, forearm and torso angle. But if you’re making radical changes, a 70mm stem on a 58cm frame or a 140mm stem on a 52cm frame, for example, is a clear indication that you might be riding the wrong frame size. The other factor to also consider when choosing stem length is the rise of the stem. If you want a lower position, opt for a stem with a negative rise that lowers the handlebar height in relation to the ground. If you're after a more upright position, a stem with a positive rise will lend you a more comfortable fit. It’s all down to personal preference. Don’t copy the pros Curvature induced in a cylinder is proportional to the bending moment, which for a given transverse load is proportional to the load (assumed fixed) times the distance from the end of the stem. So the bending moment is proportional to x, where x is the distance from the end of the stem. The deflection is proportional to the second integral of the bending, so integrating x twice yields a deflection proportional to L³, where L is the length of the cylinder.Please bear in mind that not all manufacturers provide correct imagery and we may put a similar or alternative image to the actual product for illustration purposes only.The actual item you receive may differ from that which is displayed, for example the box may have changed or a model may have been upgraded or changed after we have added the product online. Choose an angled handlebar stem for a more comfortable riding position, or an ultra-stiff and ultra-light carbon stem to achieve that aero riding position.
