I honestly don't know. This bike does...
The seat tube is 16 inches, center to top (I just measured it).
I thought it may be rubbing because of how the seat is set back above the wheel. But I am far from an expert, very far, in fact!
Ah... just googled them. They are.. pricey, LOL.
Think I'll order that pakrak. At the worst, it will be another one I have to return.
