Seat Post!

The UPS folk rock! I had to scurry away to work this evening so I placed a sign
near my door to get them to deliever the uni to the neighbours house instead…
And they did! :smiley:

So I’m happy, the uni is the pefect size etc. The blue Viscount seat is quite
nice too… However and please bare with me it’s only been out of the box for
less than 10 minutes… But on the end of the seat post there’s a big black
rubber stopper. It’s preventing the seat from being inserted with the clamp
loose. How does it manage to get fit in? Should I talk to it politely or should
I use force? :slight_smile:

Other than that it’s wonderfull! Big thanks to the people over at
UnicycleSource.com ! Now if only I had an air pump handy… Tomorrow! :smiley:

Unfortunately that tends to be more normal than it should be on Taiwanese
unicycles. I’ve had “T” unis that came with specks of weld splatter, chrome
splatter, and other crud in the neck of the uni and that made it impossible for
the seatpost to clamp in securely. If that is the problem you can carefully use
sandpaper to remove the splatter inside of the neck. Just be careful not to get
over excited with the sandpaper and sand off more than you should.

The clamp used on the “T” unis is also bad at clamping tightly. If you are lucky
the clamp is not welded on the frame so you can remove it and repalce it with a
real clamp. A double pinch bolt BMX clamp is the best way to go. Typically a
7/8" (22.2mm) clamp will fit most “T” unis. The double bolt clamps typically
have half of the clamp fit over the neck of the uni and the other half fit over
the seatpost and makes things very secure. A bike shop that carries BMX stuff
should have a good supply of BMX clamps.

Ok ok, so I was having a blonde moment :slight_smile: The seat is now in place. But I can
still move it around a bit with my hand even if it’s clamped down pretty
tightly. Is this normal?

Re: Seat Post!

Hi,

It is worth noting that the Taiwanese unicycles do not come with a 22.2
(7/8") stems, but with 22.0. OK you can scream at me and say that is nothing…
but it explains why it is sometimes hard to fit Miyata seatposts in to used
Taiwanese frames - they are 22.2 (7/8"). 0.2mm is often the reason why you
cannot tighten your seats using the standard seat clamp and I totally agree
with John the double bolted seat clamps do the job and go for the ones with
the 22.2 lip on the inside (the outside is 25.4 if I remember correctly). For
another anomaly… the Taiwanese frames use non-metric tubing - it is 22.2
on the inside, so whenever you use a 22.0 seatpost you need to bend it in to
make it fit.

I know all this because we are now making shims for Pashleys to fit 22.2 and
8. seatposts and I made the mistake of assuming that they were both the
same - then finding that the stiffer Pashley frame was not as forgiving
as the Taiwanese frames so not clamping the 22.0 posts… we now
produce both sizes!
