Technical Information

Reynolds 853 DZB Tubing

Seamless Air-Hardening Heat-Treated Steel with Double Butted Zones. The benefits of air-hardening steels are particularly noticeable in the weld area where, unlike conventional steel alloys, strength can actually increase after cooling in air immediately after welding. 853 is heat-treated to give high strength and damage resistance, and the steel properties allow thin walls to be used, so that lower weight but fatigue-resistant structures can be made. The chemistry includes carbon, manganese, chrome, molybdenum, silicon, copper. The interaction between the alloys result in a fine grain structure that forms with air-cooling without the traditional “quenching” (fast cooling in water or oil) process. High strength from bainitic phase steel after a series of cold-working operations. Heat-treatment to the 853 specification raises the yield strength for the entire tube, increasing dent and impact resistance.

Gates CenterTrack

Next generation Carbon Drive System. Unique, super-strong, carbon-reinforced polyurethane system that requires no lube and provides a nearly silent ride. CenterTrack is stronger, lighter, more compact, and better at shedding debris than the prior Gates systems.

Dropout Modularity

Patented Kobe 2 Slider Dropouts allow belt-driven or chain-driven or geared configurations

Boost 148 Rear Spacing

New standard to allow better clearance for short seatstays and big tires, plus a better spoke bracing angle for stiffer wheels.

110 mm Front Spacing

Better spoke bracing angle for a stiffer front wheel.

30.9 mm Seattube

Larger diameter seattube than most steel frames allowing compatibility with more dropper posts available in the market.

Tapered Steerer and Headtube

Stiff steering handling up front.
