hi, i did a bike fit and i have quite detailed information in a PDF format, is there an email i can send the information to you ?
garg,
I got your fit details. The fit did measure and record your Pad Y at 704mm (they are calling it "arm pad stack BB"), and your Pad X of 461mm (they are calling it "arm pad reach BB at 411mm" measured to the back of the pad, I need it to go to the middle to have a number I can use). If those numbers you sent me are right - and I studied your fit report, checked the images, I think they measured it out properly. They're might be a couple of issues of accuracy but I can say this - you left there in a better position than the one you walked in with - and that's good! The problem is this - your current arm pad elevation is 30mm (30mm below seat height). That's a very modest "drop". I would expect you to be able to ride 80mm to 100m (11-15% of saddle height). I bet you already suspect this because you recognize all of that construction that currently exists under your arm pads (spacers under the stem, the stem it pointing upward, and all of those pedestals under the aerobars).
If this really is your ultimate position then I'm afraid the 2019 Speedmax SLX won't fit you. You'd have to ride a medium to achieve the Pad X of 461 (shortest the large gets to is 471). The highest the pads will go on a medium is 650 and this fit report says you need a Pad Y of 704. Now, don't be dismayed. I have several resolutions for this...
1) Your current crank length of 170 is too long for you. I think you should probably be riding 155s. You'll need to get a crank from Cobb or Rotor or some such because the big boys (Shimano, SRAM, etc) don't make cranks that short. If you committed to that length crank then your Pad Y could be dramatically lower and you could then ride a 2019 Canyon Speedmax, size medium, rise bar, short stem, TSP and 55mm of arm pad pedestal and pads mounted center hole. The end result would be a arm pad drop of 80mm - I think you could come to love that but only with shorter cranks.
2) You could obtain a 2018 Canyon Speedmax SLX size medium, rise bar, short stem, TSP, a single 60mm + a single 20mm spacer and pads back all the way. The cockpit distance would be spot on for what you ride now. The arm pad drop would be 55mm. With this set up you could get away with 165 cranks (which Shimano makes) but, again I think you should be riding 155 or, at the most, 160s.
This is a lot of speculation on my behalf. I haven't done a consult with you I didn't ask about goals, injury history, confidence, etc. I want to be able to say that an in-person fit is soooo much better than what the best can do on a forum but sadly, that's always true.
Here's my final thought on the matter - some tri bikes are made to be long and low. Some tri bikes are made to be short and tall. You need a short and tallish bike. Your current bike is not one of those - it was forced into a position to work for you. The Speedmax is not one of those - but it too can be put into a position to work for you.
