Engineered for ambitious competitive cyclists, breakaway specialists, and endurance racers seeking class-leading stiffness-to-weight performance, the Bola ELT-R series combines precision Toray T700/T800 composite rims, ultra-smooth ceramic cartridge bearings, and Pillar 1420 ultra-lightweight aero spokes. Built around our high-engagement BL200 54T ratchet hubs, ELT-R wheelsets deliver instantaneous acceleration and wind-slicing aerodynamic stability from 1,240 grams per pair.

Toray T700/T800 Aerodynamic Rim Profiles

Each ELT-R rim is precision-molded with a targeted resin system and directional carbon layup, balancing featherlight rotational weight with lateral sprinting stiffness. Available in 40mm climbing (1,240g), 45mm all-around endurance (1,250g), 50mm aero (1,290g), and 60mm high-speed time trial (1,400g) profiles across 28mm to 32mm external widths. The CFD-refined U-shape profile stabilizes steering in turbulent crosswinds while creating a flush aerodynamic transition with modern 25c–32c tubeless tires.

BL200 54T Ratchet Hub with Precision Ceramic Bearings

At the center of the ELT-R wheelset is our straight-pull BL200 hubset, engineered with a dual-spring 54T star ratchet drive system for instantaneous 6.67-degree power transfer. Fitted with precision ceramic cartridge bearings with low-friction seals, the hubset drastically minimizes rolling resistance and watt loss at race speeds while maintaining dependable weather sealing for all-season durability.

Pillar 1420 Aero Bladed Spokes & Center Lock Disc Integration

Laced with Pillar 1420 bladed aero stainless steel spokes—offering high fatigue strength and aero efficiency at just 4.3 grams per spoke—the ELT-R series provides responsive road feedback and dampens harsh road buzz. Standardized on 12x100mm front and 12x142mm rear thru-axles with Center Lock disc rotor interfaces, the wheels ensure flex-free cornering precision and powerful braking modulation in wet or dry conditions.

Handcrafted Precision & 2-Year Global Warranty

Manufactured entirely in-house with zero distributor middleman markups, Bola guarantees unmatched build precision. Every ELT-R wheelset undergoes comprehensive ISO 4210 impact certification, computerized acoustic spoke tension balancing, and truing tolerances within <0.2mm. Complete wheelsets are backed by our 2-year official global manufacturer warranty and factory-direct technical support.
