Going 1X

The old C-Record crankset is a double 53/42.   I really like the 1X concept and I am applying it to this build.  Time will tell if its successful.

The crank is modified as a single 42.  I simply removed  the big ring and moved the small ring to its place.  The big ring has a pressed in retainer for the hidden crank bolt.

I had an old FSA crank bolt retainer and modified it with a slot and used a washer.  It feels tight but I may remove it and add some blue Locktite. Blue 242

Greazy...

After cleaning...

I will match this up to a 13-28 freewheel.  Not planning on using a chain guide on the big ring just yet.

I reviewed ratios with the best gear calculator in the known universe here:
