Come ride across Portugal with me: tinyurl.com/ycxjj853
How do you transfer your bike fit from one bike to another? A couple common problems people have are, 1) getting a new bike and it just doesn’t feel right, and 2) trying to figure out what size bike will fit them when shopping for a new bike.
I am constantly getting bikes in for review, building them up, riding them for a while and then sending them back. And many of you have asked how I set them up to fit the same.
So in this video, I’l explain my process.
I’ll explain two critical bike measurements: stack and reach.
And I’ll talk about things to watch out for when transferring your fit and when buying a gravel or road bike.
This video is supported by InGamba, with whom I am going to ride the length of Portugal - some 450 miles and 30,000 vertical feet - in three days on a trip led by Laurens Ten Dam and Ted King. Wanna come on this or another InGamba trip? Full info here: tinyurl.com/32c5xak3
Thanks to Avery Stumm of @alexeyandavery for shooting this one.

Thank you very much for this information, I have had problems getting the correct positions on my bikes. Another thing I've never heard of organisations inGampa, looks interesting, enjoy "my" beautiful country. I hope it's free for you because I saw the prices they mentioned on their website were very high. Brave of them! 😅

This is something I've always wondered about you and others who switch bikes so often. A dialed fit vs a non dialed fit can make the bike feel way way different and affect the way you think it rides. Definitely a huge variable that is not always accounted for.

Great video with enough depth and "gotchyas" covered to be something I share with friends and others needing to transfer fits. The handlebar reach and hood reach are the points most often overlooked from what I have seen, so I'm glad you hit them well.

All great information and we know it matters because 2 mm of saddle height change on a ride feels like 2"!! PRO tip, laser levels that project a plumb and level line are very common and can be had affordably at any home improvement store. Shoot that plumb line thru the center off the bb and you can nail your saddle setback, reach, bar position.. etc. Use the level line over the bike and measure down from it to nail your drop from saddle to bars. Geometry Geeks another great resource to get a clue what the actual difference between bikes is on paper.

All good! I'd add: 1) Try measuring saddle height from top of pedal body to top of saddle in line with the seat post. Pedal body heights differ as do seat post setbacks. 2) Always ensure the same saddle angle (a phone's spirit level app is useful) - it affects everything else! 3) Measuring bar reach from saddle tip is imperfect (triangles n'all). 4) We get very hung up over precise bike fit and it feels weird when we change bikes, but the body is very adaptable and slight variation will make little difference, so we shouldn't get too anxious! Enjoy the ride, don't obsess over a 1mm difference in setback!

Rather than measuring from the center of the BB for saddle height, I measure from the top of the padal at the bottom of the stroke. This eliminates the concern of cranks not all being the same length.

Very nice summary! When I was looking to buy a new road bike, I wrote a program to compute the stack and reach at the stem, given its length, angle and stack (height), as well as head tube angle of the frame, headset stack, spacers.

For years I had two different kitchen drawer find tape measures that had metric. They were basically the same worn out on the end, so I went to Amazon to buy a new one. You’d think it would be more prevalent, but a tape with metric is definitely not.

@theRidewithBenDelaney you mentioned stack and reach, how does that work in conjunction with STA/HTA? I get esp confused with gravel bike sizing since they typically use such shorter stems (seems to equal longer reach).. I'd love to get more on how interpret geo charts when you're deciding what size.. maybe I missed something in the video?

@Gufolicious 4 ай бұрын

cool tutorial, only thing i would add is, that before you can do any of those measurements you will need a perfectly horizontal floor, otherwise everything gets heavily messed up. so first make sure both truth axles are away the same amount off the floor. thanks for the video!

@TheRidewithBenDelaney 4 ай бұрын

Yes, great point. And also if you have your bike on a trainer, similarly make sure that the front and rear axles are the same height. 👍

@toshman696969 4 ай бұрын

your stack and reach should be pasted so people can understand this concept well. majority of people will go into a bike store and either shop based on looks or the bike store will do a quick measure and tell them you are a 56. a 56 cm bike can have a stack and reach wildly different between trek specialized bmc etc.

Is it possible to transfer a road fit to a mtb fit? Should saddle height be the same in relation to the bottom bracket assuming the bike is correctly sized.

@gregdurbala5970 4 ай бұрын

Ben, where do you run your cleats? Middle, all the way back? I'm curious as I'm experimenting with it and I'm finding that I prefer them more towards the middle. Pedal spacers, widening the Q factor made a huge difference in fit for me.

With manufacturers standardizing on Stack & Reach was a huge improvement for measuring bikes. Now I wish the Setback would be added to that standard. Without knowing the setback the reach is almost useless

@Chader9 4 ай бұрын

Setback it self is not a great singular value. It can be impacted greatly by simply swapping between regular and short nose style saddles. As of now, paying attention to seat tube angle and the seat post offset are key. But broadly speaking, unless you are swapping between very different style bikes (road to MTB), the general range of seat tube angle is not drastically different between bikes to prevent a "normal" saddle position for that style of bike. MTB's and Tri bikes have steeper angles while roadies have slacker. So within those genres, you can likely hit the saddle setback as needed. In cases where needed, a swap in seat post to change offset can be done.

@WowRixter 4 ай бұрын

@@Chader9 I agree with all you've said, but I still think measuring horizontally from the stack backwards to where it meets the seat post is a worthwhile measurement. Of course seat post offset, saddle length/shape also factor in. I've got 1/2 dozen road bikes and the seat tube angle/setback definitely impacts the reach and the knee-over-spindle equation

@Chader9 4 ай бұрын

@@WowRixter "I still think measuring horizontally from the stack backwards to where it meets the seat post is a worthwhile measurement." - Wouldn't that just be Effective Top Tube Length (Center of Head Tube back horizontally to the center of the Seat Tube or Seat Post)? - If so, that "old" sizing value is still considered worthwhile by many people. I know that I still look at for bike sizing and selection, since I basically agree that Reach is not the only geo number to check for thinking about actual rider fit. "I've got 1/2 dozen road bikes and the seat tube angle/setback definitely impacts the reach and the knee-over-spindle equation" - So you are at the physical limit of the saddle rail in the seat post clamp in some of those cases and still not where you want for final saddle setback? - If so, that could be a time to swap seatposts for different offset, but depending on which side of the current setup you are on, it may not be possible. - I am sure there are some people and fit cases that hit those limits. Those could be times to consider different bikes entirely or sizing swap, but with all the other geo impacts that is not always an easy change. - Complexities like that are the reason I have a massive Google sheet with geo numbers and use sites like Bike Insights to compare geo for my needs and my fit customers when needed. LOTS of numbers in all of this needed to dial in that fit :D

@WowRixter 4 ай бұрын

@@Chader9 Yes I suppose Effective Top Tube - Reach would be the setback. My saddles are nowhere near their limit, I did notice though when I converted my commuter bike to gravel, I needed a 25mm seat post offset to get the overall reach that I needed. I've had a couple of bike fits and I've gotten my bikes to where I like them. Each one though is still slightly different setup, owing to different handlebar sweeps, different hoods (Ultegra mechanical & Di2 vs Dura Ace Di2 9050 & 9200) and different saddles (Specialized Toupe vs Fizik Antares). When I had a Ti bike made I agonized over so much minutia for way too long

Yes, sir! I have that bike because a) I love how it rides, and b) I hit a deer on a descent with it, braking the prototype wheels and my hand, but only cracking the seatstays. I was working for Specialized at the time, and that was a bike from the PR fleet. Turns out they didn’t want a broken bike back… so I had Brady Kappius patch the stays and I have been riding it ever since. Good eyes.
