Can this be done?
The new post seems to be truncated ~5mm shorter than the old one, but if I were to put a triangle wedge at the trailing edge, could this post fit and be clamped in a p4?
I have to replace mine, and I can get a p5 post much cheaper than the old one at my LBS, hence the question. It seems to be the same general shape apart from the trailing edge, can anyone confirm if this is correct?
If you get the “uci legal seatpost package” (not sure what they call it) you get a wedge and I think an S5 seatpost. That probably won’t be cheap though. Despite being professionally engineered I hear it has some trouble with slipping too.
Maybe you can find a seat post on ebay for cheap?
