The Bola 700c 30 mm Asymmetric Carbon Tubeless Rim is a versatile shallow‑depth aftermarket carbon rim built for DIY wheel builders, bike mechanics, and riders needing replacement rims. It works flawlessly for both rim‑brake and disc‑brake custom builds, ideal for road racing, hill‑climb events, gran fondo endurance and light‑load all‑road / mild gravel riding. Made from blended premium Toray carbon unidirectional carbon‑fiber, this low‑profile asymmetric rim delivers ultra‑low rotational weight, balanced aerodynamics and proven tubeless compatibility without the premium cost of big‑brand carbon rim alternatives.
Important note: This is a single bare rim only. Hubs, spokes and nipples are sold separately, for custom wheel assembly or single‑rim replacement.
Its asymmetric U‑shaped offset profile solves one major pain‑point of modern wheel construction: unequal spoke tension between drive‑side and non‑drive‑side. The offset redistributes rim material to balance spoke bracing angles. After professional lacing, you get more even spoke tension, improved lateral stiffness, less truing drift over long‑distance mileage and extended overall wheel service lifeBola Carbo....
Available with hooked OR hookless bead options, plus choice of 21 mm or 23 mm internal width, 28 mm external width.
‑ 21 mm internal: optimized for 25‑38 c narrow‑profile road tyres for racing & criterium
‑ 23 mm internal: optimized for 27‑40c endurance road / light gravel tubeless tyres
Four distinct weight‑tier selections let you tune your build for your riding goals:
- 320g Extreme‑Light: hill‑climb focused, race‑day minimum rotational mass
- 340g Ultra‑Light: racing / gran fondo balance of weight & strength
- 360g Super‑Light: all‑round performance for frequent training
- 400g Standard: maximum durability for everyday commuting & rough road conditions
Tubeless‑ready straight from factory; works with standard 6.5 mm tubeless valves. It supports both tubeless set‑ups and conventional tube‑type clincher tyres. Unique selling point: compatible with both rim‑brake and disc‑brake hubs, giving builders huge flexibility for vintage‑modern mixed builds.
Lab‑tested to ISO 622 / ISO 4210‑7 cycling safety standards. Passes 750 000‑cycle fatigue testing and >40 J impact resistance. Strict in‑house quality‑control validates flatness <0.25 mm, roundness <0.3 mm, dynamic equilibrium <3 g and maximum spoke tension >300 kg. Max system rider weight is 105 kg for professionally‑built finished wheels.
Performance & Use
The shallow 30 mm rim depth delivers modest real‑world aerodynamic advantage, while keeping rotational weight exceptionally low. This makes it outstanding for hill‑climbs and punchy accelerations. The asymmetric U‑shape geometry raises lateral stiffness for snappy power transfer during sprints and out‑of‑saddle efforts. While shallow‑profile rims transmit some road vibration, pairing with wider 25‑40 c tubeless tyres lets you safely drop tyre pressures (Max 110PSI) to boost comfort and dampen road buzz.
With dual hooked / hookless bead options plus rim‑brake + disc‑brake compatibility, this aftermarket rim opens‑up countless custom‑build possibilities: rebuild vintage rim‑brake carbon wheels, assemble modern disc‑brake endurance road wheels, or build light‑duty all‑road wheels for occasional gravel excursions.

Quick Buyer Insight vs other Bola rims: This is our 30 mm shallow‑depth rim. Compared to deeper 45 / 50 mm Bola rims: much lighter, far better cross‑wind stability, prioritises climbing and acceleration, with modest aerodynamic gains. Available in hooked / hookless bead and supports rim brake builds — a rare feature among modern carbon aftermarket rims. Not for heavy‑impact gravel or mountain‑bike use.
