+FAQ

How do I choose the right length and angle for my bike?

We put together a set of instructions that can help you determine the length and angle of your existing stem and provide guidance on what to chose based on riding style - check it out here.

How is the ShockStop Stem different from other suspension stems?

There are a lot of ways the ShockStop is different - so many in fact, we wrote a whole blog post about it. Check it out here.

Can I put the ShockStop Stem on my mountain bike?

Yes and No. The suspension travel on the ShockStop (1-2cm) is optimized for the types of bumps you typically encounter on roads and light trails. So, the ShockStop Stem is not going to provide the same suspension feel as a typical mountain bike front fork suspension, which will have closer to 10-15cm of travel. However, if you use your bike primarily on the lighter trails (i.e. not aggressive downhill) and you’re looking to take the edge off of an otherwise stiff frame (e.g. a bike with a rigid front fork), then the ShockStop could be exactly what you’re looking for. The ShockStop Stem is not designed to be used on a mountain bike riding on technical downhill singletrack and if used in these conditions could become damaged and lead to serious injury.

There are two different optional mounts available: the Computer Mount, and the Utility Mount: 

The Computer Mount is an integrated mount that is compatible with your Garmin, Powertap/CycleOps Joule, CatEye, Mio/Magellan, or Wahoo bicycle computer (for options not in drop down, please email us at support@redshiftsports.com).

The Utility Mount puts a small section of tube in front of the stem that provides a location to mount anything you would normally put on your handlebar (bike computer, phone, light, etc.). 

 

The ShockStop handlebar clamp is 31.8 mm which is compatible with many modern bikes, without the need for shims. However, some bicycles have different size handlebars which may require the use of shims to fit properly into the ShockStop handlebar clamp. We have shims available for 26.0 mm and 25.4 mm handlebar sizes. 

- 25.4 mm is common on bikes with flat handlebars.
- 26.0 mm is common on older road bikes with drop handlebars. - There are other less common sizes that we do not provide shims for. However, other handlebar shim sizes may be available at your local bike shop. 

- Note that some mountain bikes have “over-sized” 35 mm handlebars which are not compatible with the 31.8mm clamp and would need to be replaced with a 31.8 mm handlebar in order to be compatible with the ShockStop Stem.



The easiest way to determine your handlebar size is to see if it's printed on the handlebar. This will require removing your current stem faceplate. 

 



If you can't find the printed size, there are a couple ways you can measure your handlebar: 

Best method: Use a pair of calipers to directly measure the diameter or take your bike to the local bike shop and they will be able to measure it for you. 

 



Alternate method: Use a fabric or paper measuring tape (or print one at https://printable-ruler.net/ ) and measure the circumference of the handlebar right next to your existing stem. 

- A 31.8 mm handlebar will be 99.9 mm in circumference at the center.
- A 26.0 mm handlebar will be 81.7 mm in circumference at the center.
- A 25.4 mm handlebar will be 79.8 mm in circumference at the center.


Keep in mind that 25.4 and 26.0 mm are very close in size. 

 



If you are not able to measure your handlebar, and you know the make, model, and year of your bike, you may be able to find the handlebar size online at your frame manufacturer's website.

Stem Angle 

The ShockStop PRO is available in +/-6 degree angle. If you are looking for the +30 deg stem please visit the classic ShockStop page.
Stem Length
If you chose the +/-6 deg ShockStop, then you will need to choose one of 5 different length options: 
 

- 80mm = 3.2 inches 
- 90 mm = 3.5 inches
- 100 mm = 3.9 inches
- 110 mm = 4.3 inches
- 120 mm = 4.7 inches 

Here's some guidance on the length selection: 

1) If you are replacing an existing stem and want to match it, then start by seeing if the length is printed on the stem. Choose the length of ShockStop that most closely matches your existing stem's length. If the length is not printed on the stem then go to #2. 

2) You can measure the length of your existing stem as shown in the following picture. The length is measured from the center of the handlebar to the center of the steerer tube. 

 



3) Once you determine the length of your existing stem round to the nearest 10 mm and choose the closest match. 

4) If you are unable to measure the length of your existing stem then choose 90 mm. This is one of the most common lengths and tends to be a good fit for most people.
