I've had a bronze saddle from Burton. Was fine and clipped gently into place.

Harder wearing, slightly more direct/positive feel to the gear changes, can feel a bit notchy at first but only takes a few hundred gear changes to wear in.

Sounds like a hall effect speed sensor. Where is it located on the car? Can you post a picture?

Thanks. That's helpful. Mine's a 150 too but doesn't have any stickers or info like yours. I heard that Caterham grind off a part of the engine to make it fit in the 7, and as bad luck would have it the part they remove is the part with the engine code on it.

Yep, should have said. Fixed cam. There seem to be a variety of codes across the fixed cam engines. Not clear if they only relate to date of manufacture or to something more significant such as design revisions etc.

Anyone know what engine code/engine number Caterham used for their run of Sigma engines? I'm tempted to find and recondition an engine from a breaker as a project but curious to know which engine code to look for.

Interested in this option as changing the mirrors over when removing the screens is currently a faff.

Mine was from Burton Power. Given this is a pretty niche product there can't feasibly be more than one manufacturer making them, so if I were buying one again I'd simply buy from whoever had it cheapest, on the basis that all the suppliers are likely buying from the same factory.

I replaced my nylon saddle bush with a brass one last spring. Gives a firm and positive gear change that shouldn't degrade with use. Mine took a few tens of miles to wear in as it felt a bit too stiff to start with, but feels great now.

They're all a bit stiff I believe. Regular use will likely loosen them up.

Yep. 👍

Tonneau cover for S3 chassis with leather seats. Zip in middle. Came with my car and now no longer needed as I've swapped the leather seats for Tillets. Appears almost brand new - I've never used them and it seems that the previous owner/builder didn't either. Open minded on price. Aiming for £200-250 or nearest offer. Will throw in postage for the right offer.

I've seen that content on RRT's site before but it doesn't seem to support @7 wonders of the world's statement above. Unless I'm missing something?

That sounds intriguing. Can you point me to some data on that please?
