Seat Adjustment

Hello, I’d like to adjust my Miyata seat angle so the back part is
more flat. Can I just take the seat off the post and bend the plate on
top of the post so it changes the seat angle? The way it is, I seem to
keep sliding onto the narrow part of the saddle. Thanks in
advance…Joe in Iowa

A lot of people do like their seats angled upward from the stock Miyata
position. Bending the plate or bending the tube before it reaches the
plate should do the job. At one point I even bent my Miyata post in the
opposite direction on accident-- landed hard on the front of the seat. But
the seatpost was harder to slide up and down in the frame after that
because it didn’t just bend in one spot-- it bent a little over several
inches of post length.

What I did on my unis was I just cut a notch out of the seat post, bend
the post to close the notch, and then welded it back together. But
probably the easiest non-welding non-bending method is to buy a two
carriage bolts 1/2" longer than what comes with the Miyata seat and buy a
stack of washers 1" high that will fit around those bolts. Then put a
1/2" stack of washers on each of the front bolts between the seat frame
and the post. I’ve never used this method, but it seems like it would
work fine.

another way would be to make a bike seat type base for the bottom of the seat. (as in two parallel rails) then you can use a bike seatpost on the attackment. this is what i did, and i can now select the angle i want the seat on, however i used a suspension seatpost and had to muck around with the seat diameters to make one fit in the standard 22.1 mm uni post hole.

I thought about notching the post, but I don’t have a torch or welder. I
also considered the shimming up the front method, but I didn’t want to
take the seat cover off yet. I tried the bending the plate method today
and it worked out good. It could still go a little more, but it’s an
improvement. I rode it into work today, two miles each way, and I was
more comfortable. I may do the air seat conversion this weekend.
