I’m starting to look seriously at n+1. MyVeloFit seems to have a bike sizing for some of the brands - any subscribers know can you plug in dimensions of non-brand bikes?
@Macy I’m unclear on what you’re asking. If you just want bike dimensions, there are a number of sites that have them and can compare to other bikes. My personal favorite is bikeinsights.com because it will graphically show you the difference between bikes (at least in the form of a wire diagram). Their database of bikes seems extensive but you can always enter your own geometries if a particular bike is missing.
The MyVeloFit Sizing tool uses a similar approach of capturing the actual rider sizing via the app, and then applying that to it’s database of bikes. The comparison tools you mention can work, but frequently require comparisons of relevant dimensions while ignoring others.
I have not tried it, but the MyVeloFit tool seems to aim for going beyond the typical Rider Height (and sometimes Inseam) references for sizing that most bike makers supply, and actually get more specific to the rider in front of the app.

@mcneese.chad ahh, got it. Thanks!
I used it on three bikes (road, TT, gravel). It generally gave ok advice, but the changes to my road saddle height caused new knee pain. It also doesn’t have much flexibility about comfort vs aero. So for the TT bike, the ideal setup for me probably varies between using bike for pure TT vs long distance triathlon.
The velofit recommendations came down raising saddle and increasing stem length on all three bikes.
For TT, also went with long bar extensions but that observation came from the Facebook TT group.
There are some online stem angle calculators that can help with finding the new fit.
problem is my stem and handlebar are proprietary (and for the looks I prefer to keep them that way)
Yep, what I was really asking was there a way to use the tool to help size a generic/ chinarello frame* before purchase. It mentions a database of bikes. just wondered was there a way of inputting frame dimensions.
*they’re probably “inspired by” a brand frame thinking about it though, which may help.
Yeah, its possible that you can find a bike model from another brand that is reasonably close to your intended model. A few millimeters one way or the other won’t likely matter with the way this tool works.

Ok. Going to share the results from my first full (fit cycle) here. Keep in mind that the ‘before’ measurement dates all the way back to last November. The ‘after’ measurements were just taken earlier today. Life and other stuff got in the way.
I did use the $75 buy-up option for human review. Jesse (one of the co-founders) was very helpful. This was my first time doing a bike fit of any kind (beyond the usual salesperson instruction of ‘stand over the bike and let’s see how it looks’). I think if you’re more of a fit novice like me, the $75 human review option is helpful. If you know your fit in and out, you likely don’t need it.
Biggest changes I made were to move the seat forward, drop it some, and spent a lot of time adjusting the bars. According to the factory specs, my bike comes with a 100mm stem (it actually measures 90mm). I’m using a 110mm stem in the after photos.
Here’s the ‘before’, apologies for the lousy background. And my excess pounds around the middle.

You didn’t mention any specific issues you had before. Can you cover those and how you feel the changes addressed those for any improvments?
Good question. Lol.
I was having lots of pain and numbness in my hands. And didn’t ever feel comfortable riding with my hands in the drops. It always felt akward and uncomfortable. After the first round, Jesse made clear that my hands were way too choked up on the bars. After getting the seat position right, I spend a long time repositioning the brake levers on the bars, adjusting handlebar angle, etc. And experimented with a 100mm vs. 110mm stem. Worked hard to try and draw a straighter line between my forearm and my hands.
Best thing I can say is that the numbness is pretty much gone, and it’s less painful to stretch out on the bike. I’m aware of the fact that my overall flexibility needs improvement.
At this point, I feel like I have a good, basic, bit fit and associated measurements. Aiming to buy a new bike sometime in the next 6 months.

Excellent, thanks for the details. Sounds like success to me, with some good learning along the way. 
Does the app take a front or back view to suggest adjustments? Or is it just from the side?
Just from the side. I recall hearing somewhere (maybe it was an interview with the founders) that the AI is best able to assess what’s happening from the side profile, and that front view is harder for the AI to interpret.
I’ve never done a fit with the more established fitting systems out there, like Retül, but it was surprising to me how much the various points of your body move around as you’re pedaling. The myvelofit AI accounts for such movement, and they make clear how the AI interpreted the video you upload. So you get a chance to see what the AI is seeing.

Have you done any extensive rides since the adjusted fit? Curious if your numb hands issue is remedied even after a few hours of riding? I’ve had bike fits done at a local fitter several times over the years and even after doing so, I get numb hands usually in the third hour of a ride when I’m more tired and body weight is likely not as supported by my upper body.
I’ve been using the adjusted fit for 3+ months now. I did another round of assessment just last week because I could (one of the benefits of the myvelofit pricing model). But I didn’t make any subsequent changes.
Just did 9.5 hours on the bike this past Saturday and didn’t notice much numbness or pain in my hands or wrists (beyond what’s to be expected from a ride of that duration). Prior to myvelofit, I’d start experiencing pain within 20-30minutes of setting out for a ride (same bike).
So in the end, moving the seat forward about 10-20mm, dropping it 5mm, lengthening the stem by 20mm and spending a lot of time adjusting the rotation of the handlebars and the brake lever position on the bars all did a lot for my comfort.

I’ve had fits done with retul and guru. I don’t recall if either of those system did any type of capture and analysis from the front and back. But then again with the bike fitters I went to I spent almost as much time with them observing me riding on my bike hooked to a trainer as on the guru/retul bikes.
Just re enacted my subscription that lapsed from last year. I like the new fore/aft bar with the recommendation. I’ve seen the bar but never the recommendation. A little bit tighter of a guardrail which is nice!
