Hey guys. I am swapping an arione for a specialized Romin Evo. The saddle placement and height have been measured out and set by my fitter. I am pretty meticulous and would love to find a way to preserve the overall fit and measurements with the new saddle. Do any of you have a sure-fire method for figuring out where the new saddle should (for/aft) go and whether I need to do anything about the height?

Height is pretty obvious, just from the center of the BB to the top of the saddle. Keep the same number with the new saddle, maybe up or down the seatpost.

As for back and forth is hard to tell because who know where the new saddle wants you to seat but pretty much probably the guy will measure their length and then adjust depending were the tip of the saddles are falling in relation with the center of the BB shell.

Probably all of this will makes sense now, right?

You can preserve the angle with a level and a stack of quarters. Stack as many quarters as needed on the low side to get the level to sit level. Don't spend them until you've leveled the new saddle.

That said, whatever measurements you make, don't think of them as rocket science. Saddles vary, they sag differently, and you sit on them in different places, so make reasonable effort to match the position, but consider it only as a starting point. Then fine tune based on feel.

Basically, do the best you can and tweak from there. Tough advice for someone who likes to measure but pretty much what I figured. Interesting tip with the quarters though.

Thanks guys, now let's hope thus new saddle dies the trick.
