I have a Giant Reign x1 bike which has 2X factory installed 22-36t 4 bolt Sram Truvativ chainring. The question is, is it possible to find 39-53t 4 bolt chainring that can be fitted to this bike or if it's not possible what tooth ratios are possible?????
The reason I want to increase tooth ratio is my bike doesn't go fast enough on downhills no matter how fast I keep pedaling but in the same trail with my hardtail 3X chainring bike I can gain speed much better.
The highest speed record on trail, downhill, with full suspension bike: 61km/h (it's not possible to go faster unless the hill is steep slope) and with my hardtail one: 74km/h (It was possible to go faster)
