Wahoo SHIFT fit
Looking for some advice from those with experience transferring a professional bike fit to a smart bike/trainer. I had a professional bike fit and I’m trying to replicate those measurements on my Wahoo KICKR Bike using the Professional Fit option. I entered the following numbers: - Saddle Height: 766 mm - Saddle Setback: -102 mm - Reach: 562 mm - Stack: 643 mm - Drop: -60 Values I used: SX: 102 mm SY: 752 mm HX: 562 mm HY: 692 mm Crank Length: 170 mm Wahoo’s numbers: Standover height: G Saddle height: 12.5 Setback: 0.7 Reach: 9.6 We recommend you purchase and install a +7° 130mm stem (31mm clamp) for best fit. Stack: 0.9 Crank length:172.5 The problem is that once I enter everything, the fit feels way off—especially the saddle height. My legs feel almost completely locked out at the bottom of the pedal stroke, which definitely wasn’t the case on my road bike. I’m wondering if I’m misunderstanding how these measurements are supposed to be entered, or if the KICKR Bike’s “Professional Fit” measurements are referencing something differently than my fit report. Has anyone run into this before? If so, what was the issue? Are there any common mistakes when transferring a professional fit to the KICKR Bike? Any advice would be greatly appreciated. Thanks!

I gave up trying to use the Wahoo software to set up the trainer and just used tape measure, plumb line & spirit level in exactly the same way I'd set up any normal bike to my measurements. Was the simplest and most accurate way in the end.
Transferring bike fit measurements to other bikes.
@Dan Smith hoping you can help me out here. I’ve had a recent bike fit resize some of my bike measurements. My bike fit was undertaken on my Ridley with Specialized power comp saddle. How would I go about transferring the bike fit measurements to my other bike? The other bike has a different (longer) saddle in length, same width (155mm), so am unsure as to how apply fore aft . I’m thinking that fore aft is measured between bottom bracket and saddle tip, and I my scenario I need to transfer bike fit fore aft to other bike, but with different length saddle. Is there a best practice method here to accommodate different length saddles? Thanks, any help very welcome.

Usual process is to measure to a point on the saddle where the saddles are the same width as each other (80mm). Find the 80mm wide point on both saddles and use that to determine setback.
🎥 Webinars - what works best for you?
We’ll be running live webinars in this community, covering Bike Fit concepts and common themes that come up here. To help plan these properly, it’d be really useful to know: - Which days/times of the week out of the options below suit you best? Also let us know by commenting below, if you're more likely to join us live, or catch up on the recording at a later time? No commitments of course, this is just to help shape things in a way that works for most people. Let us know if you have any other suggestions around timing of the webinars. Thanks in advance for your input.
