eRX-TT TIME TRIAL Electronic Hydraulic 2×10-12 SPEED Disc Brake Groupset

The L-TWOO eRX-TT is a fully electronic hydraulic groupset engineered specifically for time trial and triathlon racing. Offering 2×10-12 speed configurations with disc brake hydraulics, it brings race-level electronic shifting to riders who demand precision and consistency — whether you're carving through a criterium in Hyderabad or pushing threshold watts on a flat TT course outside Delhi.

Our Take

L-TWOO has positioned the eRX-TT as a serious alternative to the established European electronic groupset names, and the value proposition is genuinely compelling at this price point. For Indian TT racers dealing with heat above 35°C, the hydraulic disc system delivers consistent braking confidence regardless of temperature or surface condition. The electronic shifting removes mechanical cable-tension variables entirely — a real benefit on roads that can punish traditional setups. This is a groupset selected for performance-minded riders who want electronic precision without paying a premium price for a badge.

Sizing for Indian Riders

Groupset sizing here concerns crank arm length and chainring selection rather than clothing measurements. L-TWOO follows standard road crank sizing conventions — match your crank arm length to your inseam and bike fit, just as you would with Shimano or SRAM. Riders in India running compact or semi-compact gearing for rolling terrain around Pune or Coorg should verify chainring compatibility with their chosen frame's front derailleur mount.

Compatibility Notes

The eRX-TT is designed for disc brake frames with standard hydraulic hose routing. It supports 2×10-12 speed configurations — confirm your frame's rear derailleur hanger standard and bottom bracket shell type before ordering. The electronic system requires charging; keep the proprietary charger accessible, especially during multi-day events or touring stages. Compatible with standard disc brake rotors across common mounting standards.

Pairs Well With

Complete your TT build with an aerodynamic carbon wheelset for maximum speed, a dedicated TT or triathlon saddle for aggressive position comfort, aero TT handlebars or extensions for optimal positioning, and a power meter crankset or pedal system to track watts and training load effectively.
