Knee replacement at two years...

[Sylvia]

Sylvia, I emailed Tandem East yesterday and they got right back to me. The shorteners will work for adults, no problem! Very excited, thanks so much (again), this gives me hope.

Cool!! I use their shorteners on my spin bike. Just be sure to get the correct width for your cranks. I think they have a wider version and a narrower version. And it is true they do increase your Q factor.

There is one other type of shortener you might be interested in but I've never tried them. The Thorn crank shorteners almost look like they might provide a little better adjust ability. From the pictures, You it looks like they slide a bit, thus allowing you to adjust the distance, but I might be making assumptions. See what you think, and contact them if they interest you. If these do work the way I think, if you adjust them past the length of the crankarm, be sure that you have plenty of clearance when the crank arm is closest to the ground. I don't know the area you ride or if you could make sudden turns, but I wouldn't want to see you catch it on anything.

Oh and one other option... Adjustable cranks, but they are pretty pricey.

I'm so glad I've been able to be of help!! I spent a TON of time researching this stuff for myself, and met some interesting people along the way. I really found that cycling people are some of the best!! If you click on the "Gary fisher beater bike" link below, you can read about some of the stuff I was trying to sort out. You may have to do some similar things. Feel free to ping me, since I've been down this path before.
