Echo TR Splined Cranks

Description and materials
- New, high quality Echo TR Splined ISIS-type cranks manufactured by renowned Asian brand Echo.
- Each crank has been forged and then CNC’d from 6061-T6 aluminium alloy.
- The pedals and BB threads are made on a high-accuracy CNC machine, in order to ensure a high quality standard.
- Large recesses both at the outer and inner side of the crank arm help remove any excess material without decreasing its strength.
- These are splined cranks, therefore the freewheel/sprocket is not screwed onto it, but pressed into the special Echo’s own splines.
- Compatible with standard ISIS bottom brackets.
- These cranks have a 37mm offset, which helps prevent them from rubbing against the seat stays or rim brake cylinders.
- Available in 160mm or 170mm.
- Available in sand blasted black, with white Echo TR graphics.

Compatibility
- These cranks have Echo’s own splines for the freewheel/sprocket, therefore they are only compatible with Echo Splined freewheels and sprockets.
- Not compatible with any other cassette-type or screw-on sprockets/freewheels.
