The Bola ULT 35G 700C Carbon Gravel Wheelset - a ~1200g 35mm climbing gravel set with Sapim CX-Ray spokes and TPI ceramic bearings, built in Toray T1000 carbon.

Bring confident control and lightweight performance to mixed-surface rides. The Bola ULT 35G reduces rotational mass while maintaining a stable, predictable tire profile for modern gravel bikes - built for riders who split fast gravel, rough farm tracks, and long all-road days.

Buying Guide.

Internal width - 24mm: run a 35-40mm tire at 40-60 PSI tubeless for fast gravel and smooth all-road.

Internal width - 30mm: cup a 42-48mm tire at 28-45 PSI for rough gravel and rock gardens.

Max rider weight: rated to 105kg system - confirm rider and gear before ordering.

Same-depth series: the ELT 35G at $579 uses a BL200 hub, while the SL 35G at $789 moves to DT Swiss 350 - choose this ULT for CX-Ray spokes and ceramic bearings between them.

Adjacent depth: within ULT gravel, the 45G adds aero and the 50G a deeper wide bed - this 35G is the climb specialist.

Target Audience & Usage Notes.

For gravel racers, endurance/bikepacking riders, and mixed-surface riders wanting a light, CX-Ray-shod build.

Not for heavy expedition loads or DH impacts.

Requires a gravel/all-road disc frame.

Max system weight 105kg.

The Ride That Awaits.

A back-country gravel climb rises through pine forest - the shallow rim and featherlight pair float up it, the bladed spokes stiffening on each out-of-the-saddle surge, the wide bed holding a 42mm tyre at low pressure over the rock garden at the top. Free shipping, VAT included, and a 24-month global warranty with 30% crash-replacement cover mean the next summit is already yours.

Trade-offs & Considerations
Aero vs Crosswind: The 35mm depth saves about 1.5W versus a 25mm gravel rim at 40km/h; the shallow profile stays calm in crosswinds on exposed gravel.
Weight vs Stiffness: At about 1200g the T1000 layup and ceramic hub save roughly 170g versus a 1370g steel-hub gravel set; lateral stiffness stays within 5%.
Tire-Type Trade-off: Tubeless clincher on the 24mm bed runs 35-40mm tyres at 40-60 PSI, and the 30mm bed cups 42-48mm at 28-45 PSI; sealant needs topping up every 3-6 months.
Sourcing & Delivery Trade-off: Standard stock ships in 1-3 business days while a custom internal-width build takes 7-15; at about $698 it is a fraction of the price of a Zipp gravel set near $2,300.
Config Ladder: The BL100 54T TPI ceramic hub is standard; stepping down to the ELT-spec steel bearing and P1420 spokes saves about $120 but adds about 1.5W of friction and roughly 40g; the internal bed is selectable at 24 or 30mm.

Max System Weight: 105kg
Recommended Use Cases
Gravel Racing: The 35mm deep, 30mm internal bed runs 40-45mm gravel tubeless and the BL 100 54T ratchet (6.7 degrees engagement) picks up instantly on rough race terrain.
All-Road / Mixed-Surface: At about 1200g with TPI ceramic bearings, the set balances aero and crosswind stability for 38-48mm tyres on mixed tarmac and dirt.
Adventure / Light Bikepacking: The 35mm depth stays aero-neutral at trail speeds; the wide 30mm bed and low-pressure tubeless smooth out rough tracks for long mixed rides.
Climbing Gravel / Elevated Routes: The ~1200g carbon build, versus roughly 1550-1800g alloy, makes short work of ramps linking gravel sectors, paired with Sapim CX-Ray 24/24 spokes.

FAQ
Will the rim crack on rock gardens or bottom-outs at low pressure?
The rim bead area uses a thickened impact-reinforced layer; impact testing passes >60J extreme impacts (above the ISO 30J standard). Inner widths of 24/30mm accept wider tyres, which deform to absorb shock at low pressure.
If the wheel is badly damaged in extreme riding, am I covered?
Yes - beyond the 2-year factory warranty, you get 30% Crash Replacement within 1 year of purchase: a discounted replacement wheel without paying full price.
Are ceramic bearings durable in rain or rough conditions - do they need frequent service?
The bearings use dual-lip contact labyrinth dust/water seals. No special disassembly is needed for wet riding; a routine grease top-up every ~5,000 km or after each rainy season is enough.
Which tyres should I run, and at what pressure?
On the 24mm bed run 35-40mm at 40-60 PSI; the 30mm bed cups 42-48mm at 28-45 PSI tubeless over rough gravel.
Will I really pay no customs or VAT for delivery to the US and EU?
Yes. The Economy channel ships DDP - duties and VAT are fully prepaid by us, cleared in advance, delivered to your door with no extra payment to customs or the courier.
