BenKess,
Fabulous! You've got a bike that fits you well. We can take the Pad Y (aka Pad Stack) and the Pad X (aka Pad Reach) from that bike and prescribe a Canyon Speedmax from those numbers.

Let's do the easy one first: Pad X
Get the bike on a level floor and lean it up against wall or cabinets or what-have-you so that's pretty straight up and down. Measure from the center of the bottom bracket down to the floor. Then measure from the top of the arm pad down to the floor. Subtract the smaller number from the bigger number and you've got Pad X. I want it in mm but I can convert so measure with whatever's handy; mm or inches.

For Pad Y here's my suggestion...
dangle a plumb- line (this could be a piece of string with anything small/heavy-ish tied to it - a salt shaker for example) dangle that off the back of your arm pad so it's almost hitting the floor (make sure the front wheel is straight, in line with the frame). And then measure the distance from that string back to the center of the bottom bracket. That's your Pad Y to the back of the pad.

Get back to me with those numbers (or questions) and I'll have answers.
