Bontrager Paradigm SL Wheelset – Carbon Clincher Performance
We built the Bontrager Paradigm SL wheelset for riders who demand carbon performance without compromise. This premium clincher wheelset combines our proprietary OCLV Carbon layup with a 25mm internal width rim profile, delivering exceptional stiffness-to-weight balance for racing, fast group rides, and aggressive training.
The Paradigm SL features DT Swiss 350 centerlock hubs with reliable Ratchet EXP engagement and Aero Comp II bladed spokes for power transfer that matches high-end tubular wheels. We designed the rim bed for modern tubeless-ready tire compatibility from 25c to 32c, with a hookless bead that seats tires securely at higher pressures. Whether you're sprinting for the line or holding tempo on rolling terrain, the Paradigm SL responds with instant acceleration and confident handling.
Paradigm SL specifications
OCLV Carbon Construction & Rim Profile
Our OCLV Carbon layup process creates rim walls that balance vertical compliance with lateral stiffness, so the Paradigm SL absorbs road chatter while maintaining responsive cornering feel. We engineer each carbon fiber layer with precise resin content and curing schedules to eliminate voids and maximize strength-to-weight ratios.
The 25mm internal width rim profile accommodates modern tire volumes without compromising aerodynamic performance. This width supports 25c tires for racing and 28-32c tires for endurance riding, giving you flexibility to match tire choice to conditions. The hookless bead design meets current tubeless standards and allows slightly lower pressures for improved traction and comfort.
DT Swiss Hub System & Spoke Lacing
The DT Swiss 350 hubs at the core of the Paradigm SL deliver tournament-level reliability with tool-free maintenance. We spec the Ratchet EXP system with 36-tooth engagement for 10-degree pickup under load, so power transfer feels immediate when you accelerate out of corners or jump in a sprint.
Centerlock rotor mounting simplifies disc brake installation and ensures perfect rotor alignment every ride. The hubs accept Shimano HG 11-speed freehub bodies as standard, with compatibility for SRAM XDR and Campagnolo cassettes when you order those options at checkout.
Tubeless Setup & Tire Compatibility
Recommended Tire Pressure
The hookless rim design works with tubeless-ready tires from most major brands, including our Bontrager R3 and R4 models. We recommend 25-28c tires for racing applications and 28-32c tires for endurance and gravel crossover riding. The 25mm internal width supports these ranges without tire sidewall rolling or pinch-flat risk at appropriate pressures.
For tubeless setup, we suggest starting at 70-75 psi for 25c tires and 60-65 psi for 28c tires for riders under 175 lbs. Heavier riders or rough road conditions may require 5-10 psi more. The hookless bead seats tubeless tires reliably with a standard floor pump in most cases, though a compressor speeds initial installation.

Bontrager Paradigm SL Wheelset Questions
No, the Paradigm SL wheelset is designed exclusively for disc brake systems with centerlock rotor mounting. The carbon rim structure is optimized for tubeless tire use without a brake track.
If you need a rim-brake compatible carbon wheelset, consider our Aeolus Pro 3V or Paradigm Elite models which feature machined aluminum brake tracks bonded to carbon rim structures.
We rate the Bontrager Paradigm SL for riders up to 240 lbs (109 kg) for general road riding and training. For competitive racing with hard accelerations and sprints, we recommend a maximum rider weight of 210 lbs (95 kg).
These limits include rider weight plus gear, so factor in clothing, water bottles, and any frame bags. Heavier riders should maintain proper spoke tension and inspect the wheels regularly for any signs of stress or trueness issues.
Yes, the DT Swiss 350 hubs accept interchangeable freehub bodies for different drivetrain standards. The wheelset ships with Shimano HG 11-speed freehub as standard, but you can order SRAM XDR or Campagnolo freehub options at checkout.
Freehub body swaps take about 10 minutes with basic tools—simply remove the rear axle end cap, slide out the existing freehub, and install the replacement. DT Swiss freehub bodies are available through authorized Bontrager dealers if you need to switch later.
The hookless bead design on the Paradigm SL requires tubeless-ready tires specifically labeled for hookless rim compatibility. Most major tire brands including Continental, Schwalbe, Vittoria, and our Bontrager R-series tires work with hookless rims at recommended pressures.
Hookless rims limit maximum tire pressure to 72 psi per current ETRTO standards for safety. This pressure ceiling works well for 25-32c tires on road applications. Always verify your specific tire model's hookless compatibility before installation.
The DT Swiss 350 hubs need minimal maintenance compared to traditional pawl-style hubs. We recommend cleaning and re-greasing the Ratchet EXP freehub body every 5,000-7,000 miles or annually, whichever comes first.
The process requires no special tools—remove the rear axle end cap, slide out the freehub body, clean the ratchet teeth, apply fresh DT Swiss Special Grease, and reassemble. Hub bearings should be inspected and re-greased at the same interval or whenever you notice roughness in wheel rotation.
The Paradigm SL can handle light gravel and mixed-surface riding when equipped with appropriate 28-32c tires. The 25mm internal rim width supports wider tires well, and the OCLV Carbon construction absorbs vibration effectively on rough surfaces.
For dedicated gravel racing or aggressive off-road use, we recommend our Kovee series gravel wheelsets which feature reinforced rim layup, higher spoke counts, and wider rim profiles designed specifically for loose and technical terrain.
Independent wind tunnel testing shows the Paradigm SL wheelset saves approximately 8-12 watts at 25 mph compared to a standard box-section alloy training wheelset. Real-world benefits include faster acceleration due to reduced rotational weight and improved high-speed stability from the aerodynamic rim profile.
The performance difference is most noticeable during sustained efforts above 20 mph, sprint accelerations, and rolling terrain where momentum matters. Riders typically report holding 0.5-1 mph higher average speeds on similar routes after upgrading from alloy wheels.
