I've just finished my "I've got a bad back" build, using a Diamondback Master 60cm frame. As you can see in the pictures, it has a high-rise stem. Just had a "Laminectomy" on my 70+ year old (acc. to the doctor) back.
Just thought I would share with you all that life doesn't end when you have medical issues that threaten your joy of the road.
BTW, the frame is built of True Temper AVR. Do any of you have any idea where I can get information on its specs?
