The Bola CLA 700C 60mm Front / 88mm Rear Triathlon Disc Wheelset - a matched deep aero TT pair for flat time-trial courses, built in Toray T700/T800 carbon.

Fast courses, windy flats, and race-day time trials demand a wheelset that keeps speed without fluttering. The Bola CLA 60/88 pairs a 60mm front with an 88mm rear - the classic fast/steady combination - in tubeless-ready disc-specific carbon.

Buying Guide.

Internal width - 17mm (the only bed offered): run a 25-28mm race tire at 90-110 PSI tubeless for the lowest drag on smooth tarmac, or a 28-30mm at 80-95 PSI for rolling, rougher race roads.

Max rider weight: rated to 120kg system - check rider and gear before ordering.

Same-depth series: among deep-section sets at this level, the ELT 60R is lighter with ceramic bearings at $579, while the ULT 60R adds CX-Ray spokes at $698 - choose this CLA for the deep rear at the lowest outlay.

Adjacent depth: the front/rear depth split already trades stability for flat speed; reach for a shallower set only when climbing or crosswinds dominate.

Target Audience & Usage Notes.

Built for age-group triathletes, TT specialists, and fast road racers on flat-to-rolling courses.

Not for steep climbing (1700g) or very windy days on the deep rear.

Requires a disc road frame with 12x100/12x142 thru-axles.

Tubeless-ready; clincher-compatible with strips.

The Ride That Awaits.

Down the start ramp the front steers with quiet confidence while the long rear drives you forward like a tailwind you wear yourself - sustained effort feels calm and planted. The disc brakes modulate predictably when the run-up turns technical. Free shipping, VAT included, and a 3-year rim / 2-year wheelset warranty with 30% crash-replacement cover mean you commit to race-day speed without a second thought.

Trade-offs & Considerations
Aero vs Crosswind: The 60mm front / 88mm rear combination saves about 9.0W versus a 50/50 set at 40km/h on a time-trial bike, but at 10° yaw crosswind steer forces rise sharply — this is a dedicated race setup, not an all-roads wheelset.
Weight vs Stiffness: 1700g (±5g) for the deep-section pair, about 280g heavier than the 50R — the price of the 88mm rear; lateral stiffness is high and tuned for steady TT power.
Tire-Type Trade-off: The narrow 17mm internal bed pairs with 25–28c competition clinchers at 90–110 PSI tubeless, trading cushioned volume for a narrow aero trailing edge.
Sourcing & Delivery Trade-off: This deep TT build ships in 1–3 business days from stock at $618; custom width or decal adds 7–15 business days.
Config Ladder: Enduro steel bearings and a 54T ratchet (6.7° engagement) are standard; a ceramic upgrade saves about 1.5W friction for roughly +$100. The 60/88 split is fixed; a shallower 60/60 option can be quoted for windier races.

Recommended Use Cases
Triathlon / Time Trial: IM and club TT fields reward deep-section aero; 60mm front / 88mm rear profile minimises drag on flat-to-rolling courses where aero dominates climbing.
Aero Road Racing: Fast flat road races and crits on disc frames; 2026 WorldTour teams run 28-30mm tubeless — pair the inner bed accordingly for rolling speed.
Race-Pace Training: Open, fast courses where holding aero position pays off; stable crosswind handling builds confidence before race day.

FAQ
Will this wheelset bolt straight onto my Shimano groupset?
A Shimano HG freehub is fitted, so an HG cassette mounts directly; note at checkout if you run SRAM XD/XDR and we will fit the matching body.
What actually arrives in the box — rim tape, valves, spare spokes?
Each set ships tubeless-ready with rim tape, valve and spare spokes included, so you can mount tyres and add sealant without ordering anything extra.
How do the 60mm front and 88mm rear handle crosswinds on a triathlon bike?
An optimised deep profile keeps steering torque predictable at 10°–15° yaw, so the 60mm front stays composed in gusts while the 88mm rear lays down stable aero.
Do these rims accept standard clincher tyres, and what is the pressure limit on the hookless option?
Hooked rims accept standard clincher tyres directly. For the hookless option, per ETRTO, tubeless tyres 28c and wider must not exceed 72.5 PSI (5.0 bar) to prevent unseating.
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.
