Road Unicycle Set-Up and T7 Handle Modification
With that set up the fork rake will be negative which will make turning more difficult. Did you experience the unicycle wanting to keep in a straight line when trying to turn? -- scoope ------------------------------------------------------------------------ scoope's Profile: http://www.unicyclist.com/profile/17710 View this thread: http://www.unicyclist.com/thread/75372 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

Road Unicycle Set-Up and T7 Handle Modification
I laughed a bit at first about the metal fatiuge teter-totter you had developed there Gizmo, but like a lot of out of the box ideas, it sparks other ideas too. . . . . . I ride a really long set of bars on my KH36 that is run off of a beefed up rail adaptor, but if I could cut the length of cantelevered "mast" esentially in half, that would reduce some of the structural problems with this design that I've had to engineer around. I'm intriuged enough with your experiment to try to mock-up something similar . . . . a cross between my existing mast set up, but with the seat set back behind the frame somewhat. But I'm worried about the legs hitting the frame bit that you reported. Couple questions: -Do you run zero Q cranks? -Do you set your set for close to full leg extension or do you keep the seat lower than this? -Ever tried this bar set-up on a Nimbus 36 frame (with wider hub and narrower frame crown)? -Are you a race horse jockey sized rider with narrow "Steven Tyler-esque" hips http://www.bestweekever.tv/bwe/image.../06/653292.JPG or more average sized?? -Did any of your angle adjustments fix the knee/frame issue or would you have to move the seat forward somewhat?

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. -- GizmoDuck The Induni Unicycle Tour 2009. Unicycle Tour of India.

Boojiboy: I've attached another photo of me riding with a short seat extension (GB4). Notice how my elbow is almost locked at 90degrees. I have very little leverage and it's very uncomfortable to take any weight on my arms. Now just imagine the same position, but instead of my arms being locked in a flexed position, that they are placed out the front on a handlebar, with my the elbows only slightly flexed (ie like a bike). I think forwards/backwards balance isn't going to change how much, but it will be a lot more comfortable. +-------------------------------------------------------------------+ |Filename: Riding Position.jpg | |Download: http://www.unicyclist.com/attachment/30834 | +-------------------------------------------------------------------+ -- GizmoDuck The Induni Unicycle Tour 2009.

Good stuff Ken. I did a bit of experimenting with a bike seat this fall and will definitely have a bike seat and long handle on my next 36er.

I'm not the only one who thinks the T7 is too upright! You could extend the reach without getting a super long handle by sticking out another post from the back also, and mounting the seat on it. Much like what I've done with the T7. -- GizmoDuck The Induni Unicycle Tour 2009. Unicycle Tour of India.

Road Unicycle Set-Up and T7 Handle Modification
i'm not really a road rider... i prefer muni...but today i was bored and i still have my 29" schlumpf...and i thought your idea is worth to try it... it feels good, there is way less weight on my bottom...but it is still a little to short and the angles could be better... and i need shorter cranks ;-) .. i could only ride it for a short distance...hope i can try it really soon. thanks for the great idea!! +-------------------------------------------------------------------+ |Filename: DSC04139.jpg | |Download: http://www.unicyclist.com/attachment/30856 | +-------------------------------------------------------------------+ -- turtle -'platzangst' (http://www.platzangst.com/)- '-schlumpf-' (http://www.schlumpf.ch/) 'my vids' (http://de.youtube.com/user/Balzner) 'my pics' (http://picasaweb.google.de/einrad2) ------------------------------------------------------------------------ turtle's Profile: http://www.unicyclist.com/profile/11288 View this thread: http://www.unicyclist.com/thread/75372 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |

That's a neat idea, but I don't think the T7 seems strong enough... Looks like it would bend at the rails pretty soon. I don't think I'd try it. -- CoreTechs UNICYCLE FOR CHRIST In nomine patris et filii et spiritus sancti )--21stOverall-RTL2008-O )--18thCriterium-RTL2008-O ------------------------------------------------------------------------ CoreTechs's Profile: http://www.unicyclist.com/profile/15629 View this thread: http://www.unicyclist.com/thread/75372 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |
