In contrast, a short stem is usually the best option for competitive road riders. Handling is more compliant and the rider sits in a more aggressive and aerodynamic position. A short stem requires more precise movements, which can feel twitchy to inexperienced riders. Hybrid Slowpoke wrote:I am trying to understand how to interpet the angle of a handlebar stem, and have a hard time with geometry. Leisure riders will appreciate a more upright, closer position as this more comfortable and easier to control. So stems no longer than 100mm and with 10 degrees or rise will be a good option for most.

Lastly and not to be overlooked is the stem colour. Does it match your bike, bars, seatpost? A small consideration to some but once you have your position sorted there’s no point in spoiling it with the wrong aesthetics! Simply put, a longer stem provides you a more stretched out and aggressive posture while shorter stems bring bars closer to the saddle and put you in a more comfortable position. A lot of positioning and responsiveness depends on the length of the stem. While road riders choose their stem length based on bike-fit and positioning, off-road riders often determine stem length based on how the bike handles. If you are an experienced racer, most likely you have been through a bike fit process and know the length of the stem you need.would rise or drop 14 degrees if the steer tube were perpendicular. A "high rise" for some or "deep drop" for others. Stem length has a big impact on the overall fit and ride of your bike. David Caudery / Immediate Media If you are a regular rider, you may appreciate a neutral position with a slight rise in stem. Around 6 to 7 degrees of stem rise and a stem length that complements your position would suit you the best.

On my Colnago EPS, I have a Deda Zero100 stem in 110mm. The specs say it is an 82 degree stem. Looking at the stem, it has almost no rise to it. Once you choose the appropriate type of stem for your bike, it is important to determine which clamp dimensions are compatible with your steerer tube and handlebars. Steerer Tube Clamp Diameter Stems between 100-120mm of length are known as long stems and anything below 90mm is considered as short stems. Generally on a road bike stems tend not to be shorter than 90mm and longer than 130mm. In other words, for example, the following stem specs that you might see are equivalent, from lowest to highest rise (and drop): Newer bikes most likely require stems with a 1 and 1/8 in. steerer tube clamp and an oversized 31.8mm handlebar clamp. On average, it is best for casual riders to have a longer stem (70mm to 120mm) with a positive (6 to 10 degree) rise. It is worthwhile to discuss stem options and fit with qualified staff at your local bike shop.Bike stems look like a standard equipment without any science to it, however, they are highly influential when it comes to comfort and control. The wrong stem length will not only make it difficult to reach for the handlebars, it will also destabilize the steering and affect body position on the bike. The numbers are +/- because the stem can be installed to angle up or down. To get to the next level of detail, the actual rise from horizontal depends on the head tube angle. Also, if you make significant changes in the rise (or drop), you might need to adjust the length. But a change of +/- 2 degrees would change the reach in terms of a couple mm. Similar to stem length, you will have to experiment with stem rise to find the ideal balance of pedalling comfort and handling response. Older bikes have a 1” steerer but these are becoming rare and any stem to fit these types will be clearly labelled. NB: some manufacturers quote the other way ie 83° which in reality is a 7° rise so don’t expect a near vertical stem!
