Thank you Ian for your assistance in this thread.
Can I please get some assistance. I currently ride the new speed concept, size medium, long far topper. Using your video of getting stack and reach I came up with the following
Pad y (stack back of pad) 620
Pad x ( reach to back of pad ) 455
(pads have 14 degree tilt)
Seat height : 77.1cm
Rider height : 178 cm
Seat distance behind bb: 19mm with adamo race saddle
Enclosed is a pic of a club super sprint race for some idea.
I believe the stock canyon stem default allows for a reach of 460 is that correct ? When one is so close to the max setting would it make sense to order the bike with a longer stem to allow margin of error ? Does the long stem cover a shorter reach at all or is its minimum 460? I ride with larger bontrager race pads and have the elbows on them with some hanging off the back but thatâ€™s ok because of their size. Refer to pic below.
Thanks for your patience on this. In terms of the "stock Canyon stem default"... I don't think you're talking about the Speedmax CF, which of course comes with a stock stem that is sort of a mortal stem but not really and it is made by canyon. I think you're talking about an Speedmax SLX or CFR. I'm going to proceed under that assumpiton and if I'm wrong get back to me please and I'll respond in a more timely manner. So... the SLX/CFR (same geometry) ships in the USA with short stem (short cockpit) - but to say the Pad X max is 460 depends on the size of the bike - but again based on the context I think what you're asking is... "what is the Pad X range of the the proper size SLX/CFR for me?". Here we go....
With a Pad Y of 620 and a Pad X of 455 the right Speedmax SLX is size Medium, short stem, low spacer, and medium extension (everything I just listed as the proper front end config for you is stock in the USA - by that I mean you pull the bike out of the box it'll hae a short stem, medium extension and probably a mid spacer on it but in a box-o-bits that comes with your bike you'll have a low spacer and some wedges so you can add tilt). And you'll have room to push your pads forward another 9mm if you need that to a max of 464 or pull your pads back to a Pad X of 410. You're seat height will even allow for both water bottle bosses to be exposed behind the seat post so you can run that Canyon behind-the-post cage if you like.
