Brooks saddle rails too narrow.

Squidgy Black

I managed to get my hands on a Brooks B17 fairly cheap off a friend who was parting his bike, but the problem is that the rails are about 2 mm too narrow, he was using it on an older seatpost with the bolt style clamp so I think that's why it's so narrow, I'm using a 30.9mm seatpost with a microadjust clamp.

Anyone have any idea on how to re-widen the rails to fit my clamp? Unfortunately the seatpost is seized in the frame so I can't even swap it out.

If your seatpost is stuck, then you are unlightly to achieve your correct saddle height by just fitting your new saddle to an already seized seatpost.

There are many brute force methods of removing a seized seatpost, but most of these are lightly to damage your frame.

I assume that you have a steel frame and an aluminium seatpost?

If you click on the link below....This is my favourive method...You will need to make several vertical incisions into the seatpost with yer hacksaw blade, being super careful not to cut into the frame...You will eventually hear a pop sound...Just crush the prodruding stub of the post inwards with a vise-grips and remove...

I call it the seatpost-ectomy...a delicate surgical technique that requires the hands of a lady, and the heart of a lion:pac:

Good luck...and please wear eye protection....

That's for brooks' that have two saddle rails on each side, 4 in total. This is just your standard two rail, like a normal saddle.

Here's what I mean by it not fitting:

Yeah it's a steel frame and aluminum post, I'm not too keen on hacking it up yet as I haven't really had a go at getting it out with brute force and WD-40 yet, but if it comes to the point that it's badly stuck I'll try the method cheers.

The rails will spread to use the older style clamp. I've had this happen with a San Marco Rolls recently when I removed it from a bike with a modern type seat post and put it on a bike with an old style clamp.

Yup - the Brooks saddle will be taller than standard saddles so generally the seatpost has to be lowered to give the same height.
