Good cranks

It can be tough finding good quality cranks under 170mm. These did the trick! Easy to install and so much easier on my knees. Definitely a worthwhile upgrade.

Short Cranks for Stunner X

I'm glad I added the shorter cranks to my purchase. Although, it should be a switch rather than an add on for $40 since I don't need the longer ones now.
