3.5 years and 6 pages ago, sz-rider posted an idea for an on-the-cheap set of risers. I decided to use his idea and post some pics. My setup only adds 1/2" rise, but that was exactly what I needed. My total cost was about $15. Click on the pics for larger versions.
After taking off the handlebars and removing the mounts, this is what one of the mounts looks like.
Go to the hardware store, and take one of the above with you (just in case you need to compare).
I bought two of each of the following.
3/4"x1/2" collar
3/8"x3" hex head bolt
3/8" lock washer
I chose stainless steel. Its more expensive, but overall seems worth it.
When it goes back together, this is the order. The triple-tree goes between the collar and the lower rubber washer.
Don't forget to use some of this.
And here is what it looks like when all put back together.
This is my take on what you did. I could not get a collar. I searched our huge hardware chain store today and they had none. So I used 4 washes on each side. I also bought 3" x 3/8" bolts to mount the bar clamps back onto the triple clamp. You need at least 3" to allow for the extra length created my the bolts.
These cheap risers have given me 3/4" rise. What I like about using the washers is I can lower them in increments of just over a 1/4". So far I like the height.
