Fantastic titanium endurance road bike. Lightweight, comfortable geo, rack mount, electronic shifting, comfortable gearing. These are custom Van Nicholas Zyphr frames.
Fully pro tuned, torqued, charged, Di2 updated, etc. Currently sitting at Pink Puffin BIcycles.
Check geo chart last picture. Effective top tube of 571mm. It's really moreso a 57/58cm than a 59cm.
