Yep, fella local to me paid 172 + post to build an e bike, but didn't realise it did not have a disc mount.
So I bought it off him. I was gonna swap frames for my 97 m2 child carrier, but the fella selling mis measured the seatpost, I needed 30.9 for a dropper but it's a bit smaller than that and the dropper doesn't fit and I CBA to shell out for a 27.2 dropper. Dropper post is dead useful for low speed balance opening gates etc with a child on the back
