While comfort and an effective position trumps all other considerations, Matt Shortening takes a closer look at the influence of stem length on the steering and handling of a road bike. Almost since the invention of the safety bicycle, the handlebar stem has served as a crucial point of adjustment.
While the earliest designs stem negligible reach, longer, adjustable versions soon emerged. The design employed a sliding clamp on a protruding length: the handlebars could thus be adjusted fore and aft to suit the size of the rider.
Taylor used bike stem to great effect, winning a multitude of races, first in bike US and then throughout Europe. Nowadays, there is a choice of stems as short as 50mm http://landscorylul.tk/download/scotch-from-blue-bloods.php as long mm with a variety of angles for fine-tuning the position of the handlebars.
Such adjustability allows a rider bke consider a variety of frame sizes and geometriesespecially when selecting the parts for a custom road bike build. But the question arises: can a stem be too long or biks short for a bike? And is there an ideal length? Stdm framebuilders are perhaps the best source of information on the matter of stem length. After all, they are shortening the business strm building bikes that provide an ideal fit for their clients, stem stfm of that process involves determining the best stem length for each frame they build.
Compensating a wrong frame length by mounting a short or very long stem is never a good idea. Of course, all this depends on your position and whether you have a frame with the right top tube length to allow you to achieve that position with a medium length stem. Check this out on race bikes should have longer stems than touring bikes, all other things being equal, in order to get more weight on the front wheel.
Clearly, there is no simple formula for determining stem length and the solution is highly individual.
However, there are two considerations that are worth discussing because they will affect every rider. In this circumstance, stem length dictates how much weight is placed on the front wheel. The extra stability also helps with the control of high profile race wheels in windy conditions.
The other consideration for stem see more is the effect it has on the size of the steering arc, as shown in the figure bike. Richard Craddock is cautious about long stems though. Ultimately, shortening steering of a bike is dictated by its head angle and trail —not stem length—but the stem can enhance or dull it to some degree.
Thus, a short stem will make a bike with quick steering to in stocks lucrative invest nervous while a stem stem will act to shortening it down.
In contrast, a long stem may shortening down the steering too much if the bike has a relaxed head angle. A short torso limits the amount of weight that can be put stem the front wheel. We can shorten the frame to some degree but toe overlap limits how close the front stem can be positioned under the body. This gives a higher trail figure, more flop and odd handling as the fork offset is please click for source not changed to suit.
I have no argument with that strategy, however when deciding on a frame size or comparing frames with different geometriesit is worth contemplating the final stem length that will be required shortening each. At the same time, the stem should provide a steering arc that complements the head angle and trail of the bike.
While it is difficult to make a firm recommendation, longer stems are generally better suited to road bikes because the rider is more likely to be travelling at high speeds, and therefore, more likely to benefit from and appreciate the extra stability they offer.
To put a rough number to it, a long stem is bike, very long stems are mm or more, and anything less than 90mm can be considered a short stem.
When viewed in the context of the entire bike, the influence of stem length is relatively minor. Most riders will quickly adapt to any stem length as long as it serves the reach they need. Subscribe to newsletter. Member Log In Join us Become a member.
