Patented 255 TG Resin Formula DMA Test & Analysis： - After long time tests, the red line is our new high TG resin temperature 255° carbon clincher rims Graphics，TG255 is our specially developed formula. - when heating reaches 200 degree, our resin remains 79% solidness. When heating up to 230 degree as what most of you can achieve when descending, our resin can still keep 64% solidness. - High TG epoxy resin 255° be used to make rim is good enough at high temperature heating on the wheels during braking, The carbon bike clincher rims provides stable brake surface with high TG resin system. - Advantages: * Extraordinary  High Heating Resistance * High  Rigidity in brakes * High Impacting Strength * High  Stability of the resin loss rate * Better handling of lamination To learn more about rim brake wheels of different widths (23mm, 25mm, 26mm, 28mm width), please click here...
