Default Road Unicycle Set-Up and T7 Handle Modification


Thanks for all your input.

eenwieler-sander: I used a bike seat because I had all the bracket
attachments for it. I haven't tried it with a unicycle seat, but I
think a bicycle seat is actually better for this kind of setup- there is
no reason for a curved seat that is three times as thick as it should be
(ie unicycle seat).

scoope: good point about fork rake, but I had no trouble steering it.
I haven't used it in any tight cornering and haven't had enough
experience on it to give you a firm opinion yet. However, there are many
riders who use long extension handles and seem to steer ok (Sam Wakeling
and Dustin Schaap spring to mind).

BoojiBoy: Yes, you need some back and forwards movement to adjust
balance, but how much do you tilt back and forths when riding? Very
little. And no one is suggesting a position so stretched out that you
can't adjust your balance. Many riders use a stretched out position
already (see above), and I haven't seen them fall off yet. I've noticed
that when I'm riding, my back is at 35-45 degrees anyway. So the only
difference is not the tilt, it's where your hands are placed- close to
your crotch (with your elbows flexed at more than 90degrees) or further
out in front(slightly bent elbows) like on a bike.

naturequack: I"m still in talks with the framebuilder. He answers his
emails rather slowly...might give him a ring today.

agentQ and Jerrick: Yep, everything in this world has a purpose. It
took me a while to figure out what that T bar was for though.

brycer1968:
Yes, the T7 is prone to fatigue...I've seen at least 5 broken T7's.
But not sure that this will be much more fatiguing on the welds (except
now there is stress on the back welds too). The front weld I don't
think will be taking any more pressure than if you had mounted the seat
on the seatplate. It's certainly less force/leverage on the welds than
if the T7 had a longer bar sticking out from the front.
-Do you run zero Q cranks? Ye
Yes, I prefer zero Q cranks, except I don't like it on my Schlumpf
because it makes me nervous. I haven't got around to getting some
flared cranks yet
-Do you set your set for close to full leg extension or do you keep the
seat lower than this?
Same as a bike, knee slightly flexed at it's lowest position.
-Ever tried this bar set-up on a Nimbus 36 frame (with wider hub and
narrower frame crown)?
I think the issue is the tube diameter. The KH has thick tubes and a
square crown that whacks against my legs. A Nimbus frame would probably
be better, but not a fan of the wide hub. You can squeeze the frame in
though to take a regular hub.
-Are you a race horse jockey sized rider with narow "Steven
Tyler-esque"
I'm not heavy. 57kg race weight, currently about 60kg
-Did any of your angle adjustments fix the knee/frame issue or would
you have to move the seat forward somewhat?
I basically tilted the seat up and pushed the rails as far back as
possible. Although it's angled upwards it actually self corrects when
you ride it (ie the fork legs tilt forwards and the bar/seat are
relatively flat). In the photo I've tilted the unicycle forwards to
show this. It doesn't rub my legs as much on the frame, but I can't
ride with my knees pointing inwards and close to the midline like I
normally do.


monocyclism: Yes, I was referring to Pete Perons V-frame. I think it
needs to be more stretched out that what Pete has though. If you look
at that photo in the link you provided....his back is arched. If that
was a bike, you would say to the rider they need a longer stem/reach.
