Brompton seat height

[steveindenmark]

My brompton is blue so I don't think your answers would be appropriate.

Go have a look at his site. He might still talk to you even if you have an inferior coloured bike.

There's a new gadget available to solve this problem. I'm going to get one next time I'm in the shop and give it a try. The hip level thing does work most of the time but sometimes I'm in a hurry and don't get the height quite right.

Wot - ? ! ' In a hurry' - on a Brompton - ? !

My Brompton seat tube is a bit slippy, so I have to get off and alter it every half an hour anyway.

Aren't you keen to get home after a day at work?

That doesn't sound right @Sara_H Can't you get it fixed?

I'm not sure, I did ask the esteemed members here and sent a query to Brompton, but didn't get any useful answers.

I'd be worried in case it moved a lot suddenly while you were riding it. It could be dangerous. Was it not a new one you got? If so, I'd be taking it back to get checked.

That was an issue that both the good lady wife and I had with our Giant Halfway. We resolved that by replacing the quick release seat clamp with a 'proper' seat clamp requiring the user of a hex key. Before anyone comments, we both weigh about 70 kg., so it wasn't THAT causing the problem - !
BUT, neither of us have experience a sinking feeling with our Bromptons. It does state in the 'Book of Words' that the seat pin must be absolutely clean, as must the seat tube. Give said pin & tube a good rub down with a white spirit soaked cloth which should shift any traces of greasiness which may be the problem.

Not good, silly obvious 1st question - the clamp is tight enough isn't it?

I'd have the seatpost out and give it a serious cleaning and make sure the frame seat tube is properly clean inside too.

Might be worth checking with a couple of Brompton specialist LBS's that the frame and post are as they should after the road rage repairs.
