Road Unicycle Set-Up and T7 Handle Modification

Road Unicycle Set-Up and T7 Handle Modification
GizmoDuck;1166549 wrote: 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. I'm sure it would be more comfortable. During the RTL time trial I wanted to practically lay down on my T7, but just putting a little extra weight on the front and I would have to pull back to correct. Actually, I never thought about it much before, but when I ride, I'm holding on to the very end of the handles, with my palms on the last inch of handle. It seems that I would probably benefit from a longer reach like that. I think putting your main body weight behind that center line will definitely allow you to distribute more weight to the front for an easier ride in the seat. I just have very little faith in those t7 rails. It's almost painful for my brain to see your mod pictures because it's putting more leverage on an already weak point in the t7 design. But as a prototype for a new way of riding long distances, I think you're on to something. if that T7 had a straight tube instead of those rails, I think my brain would hurt less. -- BoojiBoy ---------------------------------- dreamrapper.wordpress.com www.unicyclemax.com ------------------------------------------------------------------------ BoojiBoy's Profile: http://www.unicyclist.com/profile/3923 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
After seeing the modified T7 with seat in rear I ask myself : What does this do to center of gravity? How am I effected for freemounting and riding without hands on handlebar? How am I effected for idling? Giving thought to mechanical advantage, what strain am I putting on T7 bar by moving seat to rear. It just like a crowbar prying seat post. This is a very interesting topic/post. I'm curious to what KH is upto for his development for a handle. -- legtod2 Terry Fox & Trish Crandall... my inspiration in life. ------------------------------------------------------------------------ legtod2's Profile: http://www.unicyclist.com/profile/15732 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
Thanks everyone for your input. I've modified the article on Adventure Unicyclist. It reads alot better than my first post on this thread: http://www.adventureunicyclist.com/?page_id=263 turtle: I ride XC Muni alot too, and I'm wondering if it would be practical for a MUni. After all, mountainbikes aren't all that different from road bikes. Maybe slightly more upright. I'm also toying with the idea of having a suspension shock on the front bar, or if it was a V-frame, on the front fork. CoreTechs: The T7 is not the best design for this...I've never been a fan of rails. But the principle can be applied to other designs. Instead of a superlong front pole, use two shorter ones...front and back. It will be stronger. That said, I'm pretty light, so hopefully it will hold up ok. unijuul: thanks. I've been talking about this for ages, but only just got around to putting it all together. turtle (re your second post). I think that would work. You could flip it upside down and somehow bolt the seatpost onto the seatplate (it's curved the wrong way, but nothing a bit of creativity can't fix), rather than clamping it onto the rails. I actually wanted to clamp the new KH seatpost onto the T7 seatplate, but Tony Melton told me it wouldn't fit in between the rails. Boojiboy: That was the whole point in demonstrating this concept. If you were designing this from scratch you would get rid of the complicated rail and seatplate system, and just use a seatplate and weld the front/back poles onto it. legtod2: What does this do to center of gravity? Nothing. It's more about hand/arm positioning than body positioning. Some people ride with quite upright postures. This setup might not suit them. How am I effected for freemounting and riding without hands on handlebar? I never ever ride my unicycle without my hands on the handle. It's like riding a bike with no handlebar. Fun for a while, but not very efficient or comfortable. Freemounting is a bit weird at first, but you get used to it. How am I effected for idling? I dont' know, I haven't tried idling it yet. -- GizmoDuck The Induni Unicycle Tour 2009. Unicycle Tour of India.

Road Unicycle Set-Up and T7 Handle Modification
Just logged on after a while away, and this thread is great! The "T" frame has been invented as a cheaper alternative to making a "V" frame. Design-wise, as folks have rightly pointed out, that's alot of stress at the center of the "T" (i.e. at the top of the seat tube), whether using a T7 or even a beefier arrangement. Nonetheless, I can envision a production "T" mount with many adjustable saddle & grip positions. It would have the seatpost built into the center section to eliminate the rails, and that's all you need for height adjustment. It could still have a tilt adjustment just like the U-clamp saddle mount. Thanks for the pics - as always, worth 1000 words! -- unisk8r ------------------------------------------------------------------------ unisk8r's Profile: http://www.unicyclist.com/profile/4660 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
This may be a dumb question, but couldn't one substitute a T7 for a simular length of alloy or steel pipe? That way you could still attach the seat to the "pipe" a the back, clamp the seat post to the center of the pipe (possibly with some modification or block shim) and then you have the whole front end of the pipe to work with, vary the length as appropriate and then attach/weld bike components such as bike stems, bar ends, aero bars etc... Just a thought? If I had any metal working skills I'd give this a shot. Just use a length of tubing/pipe that would fit regular bike components....hmmmm -- MuniSano ------------------------------------------------------------------------ MuniSano's Profile: http://www.unicyclist.com/profile/13350 View this thread: http://www.unicyclist.com/thread/75372 Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- http://www.usenet.com |
