The new District from Trek is the first mainstream production bike to use a belt drive instead of a chain. The carbon fiber composite belt never needs lubrication or the other maintenance associated with mechanically fastened chains. And with less moving parts, you lose less energy to friction/heat and get more energy into moving those wheels.

ReplyDeletei wonder how often this belt will need to be replaced? especially in climates of large temperature swings.
ReplyDeleteNot as often as a chain - belt drives have been used in motorcycles for a while now with fewer problems and less maintenance. Plus - it's a carbon composite material, so temperature swings won't affect it.
