Reserve 77|88 Rims

While the 77|88 profile is optimized for time trials and triathlons, they are perfectly capable of handling high-speed road riding. However, because of their deep-section design, they are most effective on flat or rolling terrain where maintaining momentum is the priority.

The rims are tubeless-ready, which means they are designed to perform best with a tubeless setup for improved puncture resistance and lower rolling resistance. You can still use inner tubes if you prefer, provided you use the appropriate rim tape.

The maximum tire pressure for the Reserve 77|88 rims is 100 psi (6.9 bar). Always check your tire manufacturer's recommendations as well, as your specific tire choice may have a lower maximum pressure limit.

No, these rims are designed exclusively for disc brake systems. They do not have a braking track on the sidewall, so they cannot be used with traditional rim brakes.

Each rim comes with the necessary rim tape and nipple washers to get your build started, along with a user manual. You will need to source your own hubs, spokes, and nipples to complete the wheel build.

Reserve engineered these rims with stability in mind, but deep-section wheels will always be more susceptible to crosswinds than shallower rims. They are designed to be predictable and manageable, but riders should expect some handling feedback in gusty conditions.
