Fitting Your Bike Are you confused about how you should fit a bike to your particular body dimensions? Have you been reading, found the terms Merxx or French Fit, and don’t know what you need? Every style of riding is different- in how you fit the bike to you, and the sizing of the bike itself. It’s more than just measuring your height, reach and inseam. With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.

Updated Fit Pics – How do I look now?

In conjunction with my previous thread, I've decided to revert back to a longer (110mm from 100mm) stem, lower the cockpit down from a stack of 50mm to 30mm, and drop the saddle height down 1/2" (from 34" to 33.5" measured from center of BB to top of saddle). I wanted to lengthen my reach a bit, and get a little more aero. I had put on roughly 100mi with the previous set up, shorter stem, higher seat, and was experiencing a lot of upper back and neck pain the morning after a ride. Always felt comfortable during the ride though.

I realize this is no where near as accurate as a proper in-shop fit, but given the fact that I won't be able to get a proper fit for some time, I wanted to post a few photos here first to glean some insight.



A couple things I'm noticing with the new set up are:

1. My reach still appears to be more upright. My upper arm isn't as close to the optimal 85° and 90° to the upper body. Optimal meaning from what I have read from various fitting sources online.

2. With regards to KOPS, my knee is quite a bit beyond the spindle. Is this ok? Perhaps I should set my seat back another 1/2" or so?

3. How does my spine, neck, shoulder posture look?

Thanks

Im no expert, In fact not even close, so take this with very few grains of salt...
but you still seem a touch cramped, aka upright. your arms are pretty straight, would be nice to stretch you out a touch and get some curve in those elbows.
You could move your seat back some, and maybe up 1 or 2mm. Your legs could extend a bit more on the pedal stroke it appears. Moving the seat rearward will increase that distance a touch, so move rearward first, then upward. does your seatpost have some setback or is it straight?
Your stem could be a touch longer, you seem tall, at least 6'2", prob taller. i would start at 120mm and consider 130mm.
You are pretty close and if you feel good after a 20-30 mile ride you are very close.

Thanks! I'm 6'4" with an inseam of roughly 37.25", maybe a touch longer. So yes, I'm long. Bike is a 61cm Space Horse, which originally came with a 120mm stem. Seatpost is straight, but I will heed your input and start by moving the saddle back a bit and see how that changes things.

I'd also say more reach, however you choose to get it.

Your posture looks excellent and you appear comfortable, if upright and closed in. I vote for increasing reach by increasing saddle setback and stem length simultaneously, and incrementally if necessary. Your arms don't look strained so try to maintain this weight distribution as you flatten out into a more athletic position. Hips back a bit, hands forward a bit. That 110 mm stem sounds like a good idea. My hunch, though, is that you'll be using the 120 before you're finished.

Set the saddle back another .25-.5" and rode this morning. Bike felt faster, and I felt comfortable extending the reach a bit more. I also have a hunch the stock set up with the 120mm stem was fine to begin with, it was just my body that needed to adjust.

Thanks for the feedback.

the frame looks a bit small for you?

I'm just guessing though

I suppose it's possible. It's the largest they offer at 61cm with an ETT of 610mm.

the eddy fit is pretty accurate .... your frame size is not far off the recomended size .... try setting up the saddle height/position and stem/handlebar position according to the Eddy fit results and see how that feels?

You look comfortable as already said but I would move the saddle back some - a cm or two. Before you move anything, mark the saddle rails with a felt tip pen so if that change does not work out you can easily return to the previous position.

The the saddle fore/aft measurement came out at 12.5cm behind he center of the bottom bracket. This is quite a difference from the above recommendations. However, I realize each bike's geo varies.

For what it's worth, the eat isn't maxed out in the rear most position, it could move back another 2cm if need be.

On my own bike, to get the saddle back far enough, I had to go to a seat post with a larger set back. When I got the saddle back with the new seat post, it took quite a bit of pressure of my hands and could also use the glutes and hamstrings more effectively. Over a number of years, the bike is now very comfortable. The only fly in the ointment now is the old saddle came to the end of its useful life and I was unable to replace it. Now I dealing with a new saddle but I don't expect finding the best position will take as long as in the past.

Your upper arms still not making 90° to your torso. Another "try moving the saddle back." I run my saddles near the rear limit adjustment on the rails, plus have a setback seatpost.
