The Wheel Size Debate: A Specialist Wheel Size?
Do We Need 32in Wheels?
Mountain bike wheel sizing has come a long way since the days of 26in wheels being the standard. Now, with 29in and mullet bikes paving the way for even more innovation, we have a variety of wheel sizes to choose from. However, the introduction of 32in wheels is raising questions about whether we need this new wheel size.
Benefits of 32in Wheels
•
- Improved roll over and momentum gathering
- Larger contact patch with the ground
- Increased traction
Drawbacks of 32in Wheels
•
- Slower acceleration due to increased rotational mass
- Tougher to corner due to increased chain stay lengths and rotational mass
Expectations from 32in Wheels
If we were to take BMC’s prototype as an example, we can expect at least early 32in bikes to bring some compromises in frame design. These compromises might include:
•
- Reduced standover height
- Lower front end
- Limited suspension travel
Specialist Wheel Size
While 32in wheels may bring benefits to taller riders and XC pros, I don’t believe that they’re going to dominate most of the facets of the sport like 32in wheels have. Rather, they’ll go the way of 26 and 24in wheels in dirt jump. 32-inch wheels will be a more specialist wheel size.
Investment in 32in Wheels
•
- Maxxis and numerous wheel brands have already invested in the wheel size
- Investment suggests that 32in wheels may pose an advantage to cross-country racing
Conclusion
While 32in wheels are certainly coming, they’re not going to replace anything. 650b, 29in and 26in wheels, to a point, won’t be going anywhere. Rather, my guess is that if they were to become popular, they’ll stick to the cross-country circuit, where clearance issues of such big wheels don’t pose that much of a limitation.
