I read through this old thread and didn't realize that I had posted here also.
I never did try a set of risers, I forgot all about them actually, until yesterday when I went to lift my seat.
I went from a stock seat , to an RDL to a slightly modified stock seat. (owner said he got it like that as a spare seat and was unaware that it was modified from stock)
I went for a 60min ride on a gorgeous sunny day and didn't realize how comfortable I was until I got home. My crotch wasn't being jammed into the front of the seat, I used my highway pegs with no apparent discomfort and I didn't remember squirming around as much as usual as I rode. After I got home I wanted to check and see where the seat was set at (I had been experimenting with high and middle) and the seat came up real easy in the front at first? I realized that the seat was riding on top of the height bar and not captured normally by the seat. Then the bells went off as I remembered this forum talking about installing risers. Guess what I'm going to do over the cold snowy winter?
I think a 2" rise is too much and 1" may not be enough, I'll figure out a new height and give it a try. I'm thinking 1.5" but will try and measure the difference in height with my seat in those two positions. (Middle setting tucked in properly up front and the middle sitting on top of the front bar adjuster.)
By having a quick look at the height adjuster, I'll have to maintain the distance from the front bar to the rear seat loop if I want to stay in the middle position front and back. I think this is best and it won't strain the seat frame. If I mimic the front bar height guides horizontal measurement from the back seat loops, I should be able to also use the low seat position front and back with the added height up front.
I have a 32" inseam and can even use the high setting since my "supposed" stock seat was modified from the previous owner to my delight!
Seems like it was Spencerized possibly as it does sit more flat and lower than stock.
I'm probably going to use either Aluminum, Hardwood or UHMW. What ever I can get my hands on first. Looks like an easy pattern to copy.
I took a few pics of the seat in both positions and even the high seat position.
To be continued....
