Brompton seat height adjustment

[chriscross1966]

Thanks everyone. Now if I can just stop my seatpost from slipping down after five minutes riding, all will be well. And I get cycle clips to stop my jeans catching on the little wheels. And I get a saddle that doesn't hurt. And comfortable handlebar grips. And I learn to stop pedalling to change the hub gear.

Clean and degrease the post and the li er in the seatpost tube. Also if the bike is secondhand it might need a new seatpost liner, my liners last about 2500 miles, so although the fun bikes aren't likely to see a new one between me changing them round a lot, the daily rider is now going through one a year.

Well. I now have a VERY comfy saddle, which looks a bit weird but my backside loves me, so there's that. I have Ergon GP1 grips, ye olde cycle clips and I gave the QR nut 1/8 of a turn, which seems to have cured the seatpost slippage. I am good to go. Thanks for all of your knowledgeable replies.
