Real-world yaw-angles are constantly changing, and turbulence from other riders can also be a factor, he explains. Take control of your bike’s handling and find your perfect riding position with a precision-designed bike handlebar stem from Wiggle. Most bike manufacturers fit different length stems across the size range, so shorter stems on smaller frames and longer stems on larger4 frames. This size-specific approach goes a long way to getting you set up with the correct stem length, providing you’ve chosen the right size frame (another area where a bike fit comes in useful). 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

Overall, I really like this stem. It's incredibly stiff and brilliant for sprints and climbs, although prolonged use on rough roads might call for you to put some extra padding on your bar and mitts. It is priced around the same as its major competitors and has some neat design features, like the Puzzle clamp, which make it look cool on the bike and function well during adjustment and fitting. Verdict We are continuously looking to improve our products. Besides a thirty-year experience in producing bicycle components, we work together with top cycling teams, athletes and mechanics to innovate and develop the best products out on the market. Every year our products are used by the top riders and cycling teams in the most difficult and demanding one-day classics like Milano-Sanremo or Paris-Roubaix as well as Gran Tours.

A frame that's too small potentially results in excessive seat post (where you will get some flex) and a very long stem will affect the steering (on a bike that's supposedly has carefully tuned handling based around one of normal length) 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.But the stem length needs to be considered as part of the bigger picture of the frame size, saddle height, saddle fore-aft adjustment and the shape and size of the drop handlebars. That’s where a professional bike fit is invaluable, as all those other factors will be considered. There are other defintions of the triangle that involve the balance of power, comfort and aerodynamics according to need, however, as described in: If you’re friendly with your local bike shop they’ll likely have a couple of spare stems and they’ll lend you one to try out, or you could try a cycling friend or even your local club. There can't be any hard numbers as we're all different, so I imagine the lead up as being on the lines of:

Whatever cycling discipline you enjoy, Wiggle has an array of bike handlebar stem spares to choose from. 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. Weight could surely have been lopped off via aluminium hardware (or even titanium but that would significantly increase costs), but only at the expense of durability. On the scales, the SL-K is a run-of-the-mill 165g for the 120mm length tested, meaning there a plenty of lighter options out there at around this price.The stem is made from a 3D forged 7075-T6 alloy, which keeps the weight down to 137g for the 110mm model tested. This is very good for an aluminium stem, with many carbon stems also sitting around this figure. It's hardly surprising, given that it's the same stem used by Chris Froome in last year's Tour de France – Sky's marginal gains wouldn't have stood for anything else. Therefore if I extend a stem from, for example, 12 cm to 14 cm, I need to make it 58% stiffer per unit length just to get the same deflection for a given load. Start with a stem that is 10mm longer or shorter, depending on whether you want to extend or reduce your reach to the handlebars, and go for a ride. 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. Never forget that pro riders are generally young men. Young men that have often made decisions about positioning and frame preferences prior to even being men.... do not think that professionals choices are made through wisdom and insight, its often not the case.

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 stem Credit provided subject to age and status. We may receive a commission if your application is successful, and the amount may vary depending on the product chosen and the amount of credit taken out.But there are many pros that clearly ignore sensible bike fitting advice and forge their own path, and pros riding smaller frame sizes and fixing the reach with a super long stem is common in the peloton. That’s why 130 and 140mm are common stem lengths, and we’ve even seen custom made 150mm stems on some bikes. The 2014 aluminium alloy used is typically used in aerospace applications, and is among the strongest aluminium alloys whilst also having high hardness – which is what you want in a stem I guess. 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.
