I have risers that are 1 5/8" tall and a additionally 1/2 riser with a 1" pullback.
Altogether, my total stack is 2 1/8" tall and has a 1" pullback.
Since the old posting, I've been experimenting with my handlebars height and pull back.
ie; I had a spare riser to experiment with {evil grin} and thought I might be able to add more adjustability to my set up.
Reasoning; When I enter a turn, I sometimes find that I'm setting to far back from the front.
Gives me an uncomfortable feeling.
Leaning slightly forward fixes the uneasiness and I can make the turn easily.
I thought a little adjustment might make me lean a bit more forward...
With that in mind, I removed 1/4" from a the (1 5/8") risers, and installed them yesterday. (risers are now 1 3/8" tall)
I'm still using the 1" pullback, so the (new)
total stack is now 1 7/8" tall.
Haven't got to ride the bike yet because of rain, but the tiny adjustment seemed to make a difference..
Ride safe, Ted
