I called and asked about that forward-facing seat clamp because I have a NOS set of Dia Compe NGC 982 cantis that I have been saving aside for a mermaid Platypus build for my wife. We both got tired of waiting for the next Platy shipment and, per a conversation with Grant, the Rosco Platy has nearly identical geometry so we getting a green 50 cm frame instead.
Anyway, Will told me that the seat clamp lug was designed for the tandem frames and that they had been worried about too much heat weakening the seat tube in that area during fabrication. Turns out that the seat stays ended up being welded lower down and further away from the lug so they decided to use up those clamp lugs somewhere else. My plan is to put a collar around the seatpost (29.8mm) and anchor a Nitto long cable hanger from there. It’ll be a minor inconvenience to adjust the collar whenever the seat height needs changing but it’s not a frequent or big deal to me. The collar: <https://www.bikethomson.com/product/seatpost-collar/> Looking forward to getting this frame!
