Our 2021 TRL bikes start with longer 21"' and 21.25" top-tube trial geometry frames with chain-stay mounted brakes. Traditional 33mm offset forks pair perfectly with the stable 74.5 TRL head-angle. We spec'd classic 29"X9", 11 back and 2 up, 2-piece bars with FIT Longtech flanged grips on all four TRL models. Other notable improvements on 2021 TRL's include double walled FIT OEM rear rims on all, female front axles, and a new U-Brake with more tire clearance and softer pull strings.
