Reminder, if a bike has truvativ/sram crank arms it's a low quality bike,


Sram crank arms:


1: weigh a ton, sand cast aluminum cranks so solid

2: cast aluminum has weak threads, any machinist knows that cutting threads into cast aluminum isn't a good idea, the proper way to do it would have been to put in a steel threaded sleeve

3: in being cast aluminum it flexes opposed to Shimano stiff hollowtech forged cranks

4: sand cast in China vs forged in Japan....for a similar consumer price


The hollowtech ii bottom bracket is not only cheaper than a square taper it's much stuffer, uses sealed bearings

The only reason a bike would run sand cast aluminum crank arms is price, they're selling you shit in a "convenient" package.

Insist on Shimano
