Current Projects chat and miscellany

I don't mean side to side I don't think, I mean that the saddle can still be rotated by hand. I think I managed to scratch the seatpost in doing so, so it isn't easy, but I don't think it's ridable without solving it first.

Doesn't sound ridable

I brought some fibre paste and my torque wrench to the track and tried again tonight. It felt alright at first but then at the end of my first lap racing it slipped down. Luckily, I had managed to leave the old seatpost at the other end of London so I couldn't race any more.

The carbon post just isn't going to work, although the 29.4mm post fit fine without overtightening, I think the clamp area has flared out a little through the previous owner using strange shims. I'd like an inline post to bring the reach down so I still don't really want to use the SystemEx post I bought as a stopgap. Should I:

a.) Buy an £8 shim and use an existing post
b.) Buy a c.£20 BBB Skyscraper seatpost
c.) Buy a £54 Thomson Elite seatpost
d.) ?
