I finally, (I say finally simply because I have been asking since December for it, really how hard is it to send an email and when I pay $250 for something I expect some level of service that does not involve me nagging), got my Retul report. This is a bit of a rant but the reality is my takeaway from Franco Bikes is that while they, specifically Julian whose name is above the door, really knows his bike stuff and whose bikes are really nice, the customer experience is pretty bad, and that’s a real shame because as a small custom shop he needs all the word of mouth recommendation he can get! Ok rant over!
So this report contains all the measurements taken by the motion based camera.
The idea here is that I can take these into any shop and be fitted accordingly. It is interesting to a point but to be honest it’s information overload. One thing that I was asked by Sean in NY was about the Knee Forward of Foot…now I was told that this is for optimum power transfer from the rotation of the pedal into forward motion. WTF? Ok disclaimer time; I am no expert here…nor do I play one on television. Firstly as best I can tell this is a variation on KOPS (Knee over pedal spindle) whereas a plumb line from your patella (knee cap) would line up with the spindle of the pedal axel, now there are arguments on this as an “golden rule” as in it is always true. See here for Pro and here for Against. It makes obvious sense that if you are drastically behind your power output is compromised and I am sure the same would be said if you were too far over. This can also be affected by the seat being too far forward or too far back, there are a lot of variables at play here.
Here are some examples of what I talking about and the photo I posted last year with the KOPS angle highlighted in green…it’s off right, you see I am behind!
As you can see there is a real science to it all. Now that being said, the qualitative variable is feel, you may be optimally fitted but just plain uncomfortable. I am still tweaking mine even after 300 miles, in fact I have lowered my seat 1cm since being refitted, this pushed my knee forward, opened the knee over axel angle and close the torso to arm angle which makes me less efficient but it’s more comfortable and that’s what counts…in my opinion!
PS I totally missed Sean’s question, so if you have asked me something and haven’t gotten an answer either in a post or email just nag me and I will get back to you…sorry again Sean!
