- 1, 2026, is generating debate over its potential impact on cyclists, particularly women.
- Critics contend that this minimum could disadvantage smaller athletes, especially women, who often require narrower bars for optimal fit and performance.
- Bike fitter James Thomas told BikeRadar that in his experience, over 80% of women cyclists need a bar narrower than 38 cm.
The UCI’s new bar width rule is creating meaningful controversy within the cycling world. This regulation mandates a minimum handlebar width of 38 cm, sparking concerns about its impact, specifically on women cyclists, who may require narrower bars for optimal performance. Critics are highlighting the potential for the rule to disadvantage smaller athletes and limit consumer choices.

UCI Bar Width Rule Sparks Controversy Over Fairness and Impact
Updated June 22, 2025
A new UCI bar width rule, set to take effect Jan. 1, 2026, is generating debate over its potential impact on cyclists, particularly women. The regulation, part of a broader release of updated equipment rules, establishes a minimum handlebar width of 38 cm, measured from the inside of the hoods.
Critics contend that this minimum could disadvantage smaller athletes, especially women, who often require narrower bars for optimal fit and performance. Some experts say the UCI bar width rule may be a blatant disregard for almost all female cyclists.
Bike fitter James Thomas told BikeRadar that in his experience, over 80% of women cyclists need a bar narrower than 38 cm.
The rule also stipulates a minimum distance of 32 cm between the brake levers. According to one analysis, even an average-height male athlete might find it challenging to comply with this requirement on a 38 cm bar, depending on lever angle.
the regulation raises concerns that the UCI bar width rule might inadvertently favor certain component manufacturers over others, depending on hood shape and lever placement.
The UCI issued a press release June 12 outlining several changes to equipment regulations, including rim height limits, helmet specifications, and fork width limits.
The question remains whether women’s teams and fitters were consulted about the bar width change. Some find it hard to believe that smaller women athletes were considered in this decision.
According to elite cyclist and fit expert missy Schwab,wider bars on adventure bikes don’t actually make a lot of sense when fit comes first. The problem is that the starting point is too wide.
Schwab said that even bikes that offer a bar on the smaller side of the trend line are speccing too wide. Instead of the common 42 for a size 54 gravel bike she mentioned considering “maybe a 38-40 bar to have a little bit more width” in case there’s a need to “stand up or really pull through.”
If a size 54 gravel bike should be running somewhere around 38-40cm bar width, what about all the smaller bikes in the pro peloton?
Critics also worry about the broader market implications. If professional cyclists are restricted to a minimum bar width, it could reduce consumer options for narrower handlebars, even for non-UCI-sanctioned events. The fear is that the cycling industry operates on a “race Sunday, sell Monday” model, influencing the availability of parts and sizes.
It’s already arduous to find 38 cm bars on bikes or for sale at the higher end. It’s even more difficult to find something smaller.That trend is starting to change as athletes realize it’s faster to run a narrower bar. Suddenly smaller riders are getting more fit options as demand grows because of aerodynamics. This rule will chill that trend, and it won’t matter if you race in UCI events, it’s going to be more difficult to find a bar in smaller sizes.
What’s next
The UCI has not yet commented on the criticism. It remains to be seen whether the organization will consider adjustments or clarifications to the UCI bar width rule to address concerns about fairness and accessibility.
