Stem Riser Vs Adjustable Stem

If we talk about Stem Riser Vs Adjustable Stem; the adjustable stems allow you to position the handlebars forwards or backward. Whereas, Stem risers are used to raise your handlebar higher than it can go naturally. When considering purchasing one of these, we want to look for grasp strength, durability, and, of course, height range. What we look for in such accessories is a strong yet lightweight grip, as well as a wide degree range.

Stem Riser

A stem riser is a hollow tube that fits over the steer tube of your fork and extends above the head tube of your bike using pinch bolts similar to those found on regular threadless stems, essentially expanding the length of the steer tubing and placing the rider in a significantly upright posture.

Stem risers are rather simple to install on a bike if you are familiar with working on the bike and have the necessary tools, but there are a few points to keep in mind.

While the riser handlebar and stem with a higher degree of risk can add a couple of inches to the height of your handlebars, stem risers can increase them by up to six inches (15cm).

With such a substantial increase in handlebar height, the present shifter and brake wires may be too short for the new location, necessitating the replacement of longer cables, making the job more complicated and time-consuming than a simple stem swap.

For bikes with such a steer tube that is cut too low and requires additional elevation to the handlebar position, a stem riser is an excellent solution.

They function well for the intended purpose if properly installed, but keep in mind that the handlebar ends up in a rather set position and on-the-fly adjustment is not possible, so make sure that the new position will fit whoever would be appropriate for the rider.

Spacers can sometimes be used for micro-adjustment; however, this is entirely depending on the length of your steer tube as well as the sort of stem riser you’re using.

Pros & Cons

  • Excellent for tall folks.
  • Installation is simple.
  • Sturdy
  • Only able to move up and down
  • Adjustment is not possible while riding.

Adjustable Stem

Adjustable stems are stems that can be adjusted up or down without having to remove them from the bike or move any spacers.

The basic construction of most adjustable stems is the same: there is an upright section that attaches to your steer tube much like a conventional fixed stem, but rather than the fixed stem “neck,” there is indeed a hinge with bolts that can be released to vary the stem angle up and down.

Adjustable stems are just as simple to install as standard stems, and once installed, all you must do to change the handlebar height is follow the instructions, which would primarily involve adjusting either one of two bolts, setting stem rise, and then retorquing the bolt.

With a simple hex wrench, adjustable stems make it simple to alter the seating position on the bike.

If you have a bike that you frequently let members of the family and visitors ride, this is a terrific method to quickly make your bike fit them better.

Adjustable stems make it simple to share the bikes with many people.

Pros & Cons

  • whole range of motion
  • Simple to modify
  • It makes it easier for people to share a bike.
  • They do not reach as far as stem risers.
  • greater cost
Adjustability The handlebars are raised and lowered by a stem riser. It does not permit forward or reverse the movement. An adjustable stem allows you to tilt the handlebars up to 60 degrees. It does not rise and fall.
Grip A stem riser, with bolts holding it in place, will grip tightly to your bike, making it a safe option. When installed, an adjustable stem is identical to a stem riser. The main distinction is that it has an additional component that enables back-and-forth mobility.

This element must be thoroughly tightened using a hex wrench. If you’ve let someone else ride your bike, make sure to verify the grip tightness of the adjustable stem before you ride.

Height A stem riser may raise your bike’s handlebars by up to 210mm, which is a significant increase in height. An adjustable stem can likewise raise your handlebars, but only to a considerably narrower range of 85 to 100mm.
Durability The majority of stem risers are composed of aluminum alloy, which is lightweight and robust. Cheaper solutions use thinner metals that corrode rapidly, so don’t always go with the cheapest option. The adjustable stem is more durable since it is more complicated. It is constructed using the same material as stem risers.
Safety Ensure that the stem riser is not built of carbon steerer tubes for maximum safety. This material is relatively thin and, if broken, can jeopardize the stability of your bike.

Also, with non-carbon steerer tubes, the stem risers are thin, so intense biking is not recommended.

Because adjustable stems cannot be made thin, they will always be strong. Although an adjustable stem allows for some wild rides, mountain biking is still not recommended.
Weight The typical stem riser measures approximately 200g and 250g because of its light material and simple construction. The typical movable stem weighs between 280g and 350g because of the added pieces.
Installation The installation of a stem riser is simple and can be done by anybody. It is designed to fit often these commercial bikes, but double your bike size before purchasing. Installation is similarly simple. As with a stem riser, make sure the part fits your bike.
