Generally a riser bar won't change reach, but 4 spacers, if they're 10mm each?? Will shorter your reach by approx 20mm depending on HT angle. You just might really like shorter reaches and prefer a more upright and/or rearward biased body position? I've played around a lot and like a pretty low stack, longer reach and being more forward and low over my bike. But it really is all about personal preference, which is what some manufactures are trying to offer. Make a bike with a low stack (short head tube) and longer reach... if that's what you like, ride it. Want less reach and more stack, add some spacers. Want to keep the reach but like more stack, add a higher rise bar. And fine tune with stem length.
But Canyon hasn't given us the ability to tune our ride here (as the stack is already fairly standard) so you can't shorten the effective reach by much.
