ProsFast shipping. Great piece of kit
It's not easy to find a 1" carbon fork expander. The M-part one is just great, with a perfect finish all round and a cool carbon ahead cap with minimalist logo.
Overseas shipping from SJS was fast and hassle free.
Thanks.

Il prodotto è della misura giusta per una forcella da 1 pollice e fa quello che promette. L'expander mi sembra di buona qualità, anche se il tappo di chiusura è diverso rispetto a quello raffigurato in figura
Good Quality Product At A Reasonable Price

Hi I need a expander for my 1”Mizuno 700c Carbon Steerer forks the internal diameter is 18mm would this work or can you advise an alternative..
Cheers Richard
Hi there,

Unfortunately the smallest that this will fit is 20mm, and we do not sell anything else that would be suitable im afraid.

Thanks.
Will it fit a stem that has its own top cap?

I have a Merida Warp TT bike and it has a 1 in steerer tube fork (20.5 mm approx inner diameter) and a special stem with its own steerer tube top cap. Does this M:Part expander use a special cap with internal threads (like the FSA model) or would any regular top cap and bolt work? I would simply use the Merida cap and bolt. A picture of the expander with the top cap removed would greatly help.
Hi there,

This uses a standard top cap/nut not an internally threaded one.

Thanks
