Spot Brand Rocker SS Frame Only

Spot has rethought the way a vertical slider-style dropout should come together (literally). Not only does it allow both belt-driven and chain-driven single-speed configurations, it also gives you the option to add a derailleur and "gear up." The unique compact system also gives you the ability to remove and replace the rear wheel without having to adjust belt tension. Add a redesigned super-strong frame connection to the mix and the Spot rear dropout system is the strongest, safest, least fussy and most versatile you'll find anywhere.

Gates CenterTrack CDS:

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.

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.

Dropout Compatibility:

Patent-pending Kobe Slider Dropouts allow belt-driven or chain-driven or geared configurations
