Will My Brakes Open Wide Enough?
A common question we get regarding wide wheel fit is if the brakes on the bike will open wide enough. The answer is most often yes. The video below walks through adjusting brakes along with moving spacers for more room.
Tire Height & Width
Over the last decade, we’ve seen the trend toward wider tires (wider is faster), but bikes are not as adaptable to tires as wheels. When it comes to wheel fit, you’re actually more often restricted with tire size rather than rim width. Below is a guide to help you determine the tire sizes that will work on your rim. Note, these are general guidelines and may not be the case for all bikes.
Bike Model Year | Tire Size That May Cause Fit Issue |
---|---|
Pre – 2011 | 23mm |
2011 – 2017 | 25mm |
2017 – 2020 | 28mm-32mm |

Brake Track Width & Your Brakes
If you have a disc brake bike, then you can skip this section. FLO All Sport wheels will fit most, it not all, disc brake bikes.
If you are still unsure and have a rim brake bike, you will need an understanding of how wide your brakes will open. To do this, release the brake cable bolt and open your brakes as wide as possible and measure the distance between you brake pads. FLO All Sport wheels are 28 mm at the brake track. If your measurement says 30mm, you are in good shape. Most modern (last 5 years) brakes will open wide enough. We know that most Shimano, SRAM, TriRig, FSA, etc made in the last 5 years open up with plenty of room.
If you have any questions on fit specifically, with your bike, please contact us and we will be happy to talk you through it.
