TNT MOUNTAIN CRANK ARM SET

TNT uses the same arm set to make mountain cranks. The spider is machined from 6.3mm thick aluminum plate. Like the Kooka Kranks, the TNT spider has three sets of fixing bolt holes. The middle/outer set of holes has a 110mm BCD. The inner holes are drilled at 74mm BCD, with the inner most set drilled at 56mm BCD so the Suntour Micro Drive 20 tooth can be used. Both sets of inner bolts leave you a choice for the inner of either a 74mm or a 56mm, but not both. The 56mm inner holes however leave the user the option of down to a 20 tooth for a much lower gear ratio.

		




A set of spacers is included for the inner fixing bolt set which ever set of holes is used. The arms are available in 175mm or 180mm in Blue, Black, Green, Lavender, Red or Silver, with the spider in Silver. We found the Mountain cranks had a Bike-Pro Q measurement of 144mm. The arm set doesn't come with chainrings, outer fixing bolts, crank bolts or crank arm dust caps. The set does come with inner fixing bolt spacers, and the 175mm long set weighs 403.5 grams, with the spacers weighing 5.5 grams.
