Miyata seats & seatposts

Hi all–

I got a Miyata seat for Christmas (thanks, dad, and thanks, John @
unicyclesource!), but it doesn’t fit the standard four-bolt seatposts on my
current unicycles (you know, the kind that fit Viscount and Schwinn/Semcycle
seats). Is there an easy fix for this? Thanks for any info–my bum is looking
forward to riding on a Miyata air seat …

Re: Miyata seats & seatposts

Do Viscount and/or Miyata come with different sized posts? It appears so,
because I tried to do the exact same thing last week and the Miyata post was a
smaller diameter than the Viscount.

My advice will be to call Tom Miller from The Unicycle Factory (765-452-2692).
He should be able to help you.

Re: Miyata seats & seatposts

Well, I can tell you that my Coker came with a Viscount seat & post. I swapped
in a Miyata seat & post and it fit perfectly. Yes the posts are incompatible
bolt-wise, but appear to be the same diameter. Of course if your current
unicycle has a bolt through the post (like the Semcycle Deluxe) then you need to
drill through the Miyata post. It may seem like a lot of trouble, but you’ll be
happy you did it.

                               Good luck,
                                 Nathan

RE: Miyata seats and seatposts

Your question sent me to the garage with a calipers since both seats are in use
at our house. As nearly as I can tell the seat post diameter for the Miyata and
the others are the same, only the bracket at the top is different. If this is
true, you should be able to interchange the seat posts, although it may be
necessary to drill a hole in the miyata post if you want to install it on a
unicycle with a split frame. Also a difficulty might be the Miyata seat post
extensions are bigger in diameter so it may be difficult to put a long Miyata
seat post in a split frame. You could but the Miyata seat post and have a
welding shop transfer the bracket to a 7/8 od tube. Good luck

Re: Miyata seats and seatposts

It seemed to me that newer unicycles seat posts have become a standard
22mm. Older unicycles have 7/8 and 13/16. The Telford uses the 25mm post as a
selling point because it can be swapped for many bicycle seat posts. Of
course unicycles don’t use the same seat clamping system. It would be
interesting if an after market post was developed that had a bracket
drilled to take either seat bolt pattern. Since the market is so small, I
don’t see a company taking on the task of making after market unicycle
parts. After first seeing all the sites with muni, about a year ago, I
contacted Phil Wood, who makes after market bicycle parts and asked about
the possibility of their being a Phil Wood unicycle hub, he told me that
they had worked on a unicycle hub. He told me if he could find someone to
sell a bulk number of hubs to his company would be interested in making
them. -Mary

Pashley and DM unis use either 25mm or 25.4 mm - which is which I’m afraid I
can’t recall (it is always possible that older/newer models vary too - I do know
that my oldish DM and youngish Pashley have incompatible seatposts - but not
that far off…)
