raising handlebar stem

[jack sprat]

I have a bad back and need to straighten my posture. The base riser diameter of my Hyperscrambler 2 appears to be different than the risers offered on Amazon. If anyone out there can direct me, it would be appreciated. I need a riser to go at least 5 inches. Maybe a standard bike riser will work. I don't know. Thanks, Jack

I use this 4.6" stem riser from Delta on all 3 of my bikes:

It fits bikes with 1 1/8" (28.6mm) stems. Don't know if it will fit Juiced bikes, but you can always return it.

Not familiar with your bike.. but looking at a photo you may be able to loosen the stem and roll the bars toward the saddle for a more upright position.
If you post the measurements of the steer tube someone might know of a stem riser that'll fit.
If unavailable different bars might do what you need.
