Bontrager Aeolus Pro 5 Wheelset
The Bontrager Aeolus Pro 5 wheelset combines a 50mm OCLV Carbon rim with our Rapid Drive hub technology to deliver race-winning speed and confidence across road and mixed-surface terrain. We engineered this wheelset for riders who demand aerodynamic efficiency without sacrificing stability in crosswinds or versatility on varied surfaces.
The 50mm rim depth strikes the ideal balance between aerodynamic advantage and real-world handling, while our OCLV Carbon layup provides exceptional stiffness-to-weight performance. Each wheelset is tubeless-ready and ships with our DT Swiss internals for dependable engagement and service longevity.
Whether you’re attacking crits, logging base miles, or exploring beyond the pavement, the Aeolus Pro 5 delivers consistent performance with the bombproof reliability Bontrager riders expect from our premium carbon hoops.
Aeolus Pro 5 Specifications
OCLV Carbon Construction and Rim Profile
We manufacture the Aeolus Pro 5 rim using our proprietary OCLV (Optimum Compaction Low Void) Carbon technology, the same process we developed for our professional race frames. This compression-molded layup eliminates excess resin and air pockets to maximize strength per gram while maintaining compliance that smooths road chatter and vibration.
The 50mm rim depth represents years of wind-tunnel testing and on-road validation with Trek-Segafredo professionals. This height delivers measurable aerodynamic gains over shallower options—especially at speeds above 25 km/h—without the steering instability that plagues deeper-section race wheels. The 23mm internal width supports modern tire volumes from 25mm slicks to 50mm gravel rubber, allowing you to run lower pressures for improved traction and comfort without risking pinch flats or burping.
Rapid Drive Hub Technology and Engagement
At the heart of the bontrager aeolus pro 5 sits our Rapid Drive 108 rear hub, featuring a DT Swiss 36-tooth Star Ratchet mechanism with 108 points of engagement. This translates to just 3.3 degrees of freewheel rotation before the drivetrain engages—critical for explosive accelerations out of corners, technical climbs with momentum shifts, and sprint finishes.
The Star Ratchet system uses two spring-loaded toothed rings that mesh under load, distributing forces across multiple contact points rather than concentrating stress on individual pawls. This design requires minimal maintenance and tolerates contamination far better than traditional pawl-and-spring hubs. We pre-load our hubs with DT Swiss grease formulated for 3,000+ kilometer service intervals under normal riding conditions.
Tubeless Setup and Tire Compatibility
Every Aeolus Pro 5 wheelset leaves our facility tubeless-ready with pre-installed rim tape and included tubeless valves. The hookless rim interface meets current ISO and ETRTO safety standards for tubeless tire mounting, ensuring reliable bead retention at pressures from 50 to 73 psi depending on tire width and rider weight.
We recommend running 25-28mm tires at 60-65 psi for pure road use, 30-35mm rubber at 50-55 psi for rough pavement and chip seal, or 38-50mm gravel tires at 35-45 psi for mixed-surface adventures. The 23mm internal width provides excellent support across this entire range, preventing tire squirm under hard cornering while maintaining the supple ride quality that defines modern wide-rim performance.

Bontrager Aeolus Pro 5 Wheelset Questions
No, the Aeolus Pro 5 is designed exclusively for disc brake systems. The carbon rim has no brake track and requires Centerlock disc rotors mounted to the hubs.
If you need a rim-brake wheelset, we recommend exploring our Paradigm or Affinity series, which feature aluminum brake tracks compatible with traditional caliper brakes.
The 23mm internal rim width officially supports tires from 25mm to 50mm measured width. We’ve tested the wheelset extensively with 28mm road slicks up to 50mm gravel tires without clearance issues in most modern road and gravel frames.
Check your frame and fork manufacturer specifications to confirm clearance, especially if you’re running wider gravel rubber. Actual tire width can vary by manufacturer even when labeled identically.
Yes, the wheelset ships with a Shimano/SRAM HG freehub body, but you can purchase SRAM XDR and Campagnolo freehub bodies separately from Bontrager dealers. The conversion requires a standard DT Swiss freehub tool and takes about 10 minutes.
The SRAM XDR body is necessary for 12-speed SRAM Eagle or RED eTap AXS cassettes with 10-tooth small cogs. The Campagnolo body fits 9/10/11/12-speed Campy cassettes.
We recommend inspecting and re-greasing the hub bearings and Star Ratchet mechanism every 3,000-5,000 kilometers under normal conditions, or annually for recreational riders. If you frequently ride in wet, muddy, or salty conditions, service intervals should be shortened to 2,000 kilometers.
The DT Swiss internals are designed for easy home maintenance with basic tools. Hub service kits are available through Bontrager dealers and include fresh grease, seals, and detailed instructions.
Recommended tire pressure depends on tire width, rider weight, and terrain. For 25-28mm road tires, start with 60-70 psi and adjust based on comfort and handling. Wider 30-35mm tires typically run 50-60 psi, while 38-50mm gravel tires perform best at 35-45 psi.
The hookless rim design requires adherence to maximum pressure limits printed on tubeless-compatible tires—typically 72-73 psi depending on tire manufacturer. Always verify your tire is hookless-compatible before installation and inflation.
Yes, all Bontrager Aeolus wheels include a two-year manufacturer warranty covering defects in materials and workmanship. We also provide lifetime crash replacement coverage that offers a one-time discounted replacement wheelset if yours is damaged in a crash.
Warranty claims must be processed through authorized Bontrager dealers with proof of purchase. Normal wear items like bearings and freehub mechanisms are excluded after 12 months but remain serviceable with replacement parts.
The Aeolus Pro 5 is optimized for road and gravel use, not cyclocross or mountain bike terrain. While the carbon rim construction is strong, the 50mm depth and relatively narrow 23mm internal width aren’t ideal for aggressive off-road riding, mud clearance, or wide mountain bike tires.
For cyclocross, consider our Aeolus Pro 3 with a shallower 37mm profile and better mud clearance. Mountain bikers should explore our Line or Kovee wheelsets designed specifically for trail and enduro applications with wider rims and reinforced spoke patterns.
