HI Ian,
I have just ordered the Speedmax CFR size M. Post sale i've been asked to choose from a few options being; Flat Bar or Riser Bar - in either stem 85mm or 65mm
and Extension Bars of Short Medium Long
Any help would be greatly appreciated. My details are;
Height: 184cm
Inner leg length: 88mm
Forearm length: 36mm
Weight: 79kg (ie. not large)
First Tri Bike so not really sure what i'm doing. Plan is for middle to long distance.
I'm too close to age 50 for my liking but reasonably flexible (not sure if that is relevant). Don't really know/understand about the stack,reach, pad x/y. Let me know if you need me to do more measurements
Thinking of going with the Riser Bar to make it a bit more comfortable when cruising in traffic etc.
Very excited to get the bike as it's been a long wait. Once i get these details to them i should get the bike in 2-3weeks (by their estimate).
thanks again, Matthew
Mathew,
I got answer and I've got a question below so hang in for that too.
You've got slightly long legs for your height so I'm gonna put your Pad Y in the neighborhood of 650 and your Pad X around 480. Based on that, yes the Medium CFR is the way to go. I think you're gonna need the long stem (85mm), and you'll probably run either the mid or the high spacer (you're right on the cusp) and to that end I too think you should get the rise bar. The medium extensions should be fine.
Now, a quick comment... just for basics... Stack and Reach are terms to describe a place on the frame, a spot actually. That spot is located at the top of the center of the headtube. We arrive there by imagining a cartesian graph, an Y and X axis emminating from the center of the bottom bracket. Then we slide along the X axis and measure up the Y axis to top of the headtube to get the "rise" of the frame (the Stack). Then we slide up the Y axis and measure out the X axis to top of the headtube and "run" of the frame (the Reach). That works for all bike frames: tri, road, gravel, mtb, you name it. When we go to a tri bike (esepcialy a "super" tri bike with an OEM, Original Equipment Manufacturer, stem) then we need to keep on with the cartesian graph but we're gonna now measure to the back of the arm pad so rather than creating confusion with terms like Pad Stack and Pad Reach we just shift to Pad Y and Pad X. The guy behind this site (Dan Empfield, AKA Slowman on the Forum) has a rich history in bikes - he invented the triathlon bicycle and he invented the terms Stack and Reach and the concept of measuring a bicycle this very logical way. If you're curious you can learn more about Stack/Reach, PadY/X here
