Dialed in the TT fit today at the best fit studio in Cincy, BioWheels. Mitch uses his years of bike fit and bike racing experience as well as the highest tech tools in the industry to optimize every aspect of the fit. Hands down the best in the biz and the only dude in town who will work on my bikes.

I was amazed at all the data collection points and how well that translated into real world changes on the bike that actually felt much more comfortable. If folks only knew they didn’t have a clue about bike fit, they would be coming to you in droves! I am going to share my data and let people know what a great investment a bike fit is!

OMG I would not have believed that just a few small adjustments made such a huge difference. NO back pain other than the usual fatigue when you do a hard ride. My hip and foot numbness...TOTALLY GONE! This honestly is the best I have felt since the bike was purchased. I am so comfortable with the new lower position and it was easy to keep my arms bent because I was not falling forward the entire time. It is wonderful to feel powerful again on the ride.
— Olivia Lally, 49, recreational road rider
I have to say that your adjustments and new equipment you recommended (cleat extenders, longer Speedplay axles, new shoe inserts, shorter stem, etc.) I am stunned at how much of a difference they have made. ...I’ve been up Amsterdam 3 times since your adjustments and haven’t stopped once on them, and I just rode 60 miles yesterday (the longest by me by more than 15 miles) and I felt just fine afterwards — only tired. My more upright position allows me to breath easier, my shoes feel better, my toes don’t go numb, and my knees don’t bow out or get sore. Now I feel like I should have visited you much sooner.
— PJ Combs, 55, recreational road rider
Mitch is the ultimate professional. He treats everyone with respect, whether you are a newbie like myself, or a seasoned rider. The fit is worth it, whether buying (a bike from him) or not. He spent the time making me practice unclipping from my pedals to reduce chances of falls, as well as appropriate shifting, riding areas. 3 weeks after my bike purchase he emailed me to ask if there were any issues that he could assist with. Best bike shop experience ever.
— Lester Doplechan, 48, recreational road rider
Just another update fyi. Had pretty much a breakthrough last night. Just my typical short 15 mile ride, but did my fastest time ever with my fastest average speed and fastest max speed. Felt totally great with my seat and hands totally fine the whole time. Also had a breathing breakthrough. Just all around great ride. So glad I had the fitting done. Everything’s changed.
— Shawn Rose, 40, recreational road rider
Remember how bad my fit was when I first came in? I probably wouldn’t be cycling still if I hadn’t come by for that Retul fit 3 years ago.
— David Wise, 55, recreational road rider
Really, that was awesome. And thank you for the fit because 1. I learned a lot 2. I have never felt comfortable until now! I can’t thank you enough!
— Matt Wright, 36, Triathlete
I can’t describe how much better my bike legs stayed fresh and I could tell a huge difference in efficiency and felt fantastic and I can tell a major difference. I believe everything will continue to improve with each ride and I want to thank you for this.
— Josh Evans, 42, Triathlete
I went for about an hour yesterday, the bike was amazing. Took some time to get used to it, but my cadence on the flats was way stronger. Climbing also improved with the longer front end. Overall an awesome improvement.
— Willam Baker, 62, recreational road rider
I have ridden twice on the road and once off-road. In short, I love it. I feel like I am getting significantly more power to the pedals. I have been trying to find a negative with the new fit, but cannot. Thank you so much!
— Seth Nuckols, 31, cyclocross & road racer
Wow what a difference! I really did add around 2 mph to my average ride speed and I feel a lot stronger during climbs.
— Tina Ulanowski, 50, triathlete and road rider
I wanted to give you a quick update...your positioning updates have really helped. For a beginner I’m making great strides I just finished a 50 mile Loveland trail ride last Sunday at a 19.25mph pace so I believe I am really starting to get the hang of this and I can tell it’s definitely a sport I can excel in and enjoy. Better yet, I’m halfway to my century ride goal so I’ll have to amend my own goals.
— Michael Lorenz, 28, recreational road cyclist
Just touching base to let you know my rides since the Retul fit have been awesome! I can’t thank you enough, I’m having the best rides ever.
— Cathy Doxey, 60, IM triathlete
New fit added 2mph for me! I felt real smooth and strong on the bike. Averaged 23.1mph when normally about 21mph. I had virtually no leg fatique the entire ride until the last 5-6 miles and still ran very well...6:36 splits. Overall 4:35 (previous PR was 4:50) and a third place finish!
— Jonathan Bade, 30, triathlete
Had a great 20 mile ride yesterday morning on what feels like a totally different bike. The hips and back feel great.
— John Lowe, 62, recreational road cyclist
I’m very happy that I went with the Retul fit. I can tell a huge difference, especially while climbing, I just feel much more comfortable on the bike.
— Mike Wissman, 36, adventure racer
Where I live (Florida), there are no bike fitting locations within a few hundred miles. So when I came home for Christmas this year, my brother suggested Mitch to me. The fit alone was phenomenal. My previous geometry was all wrong and I didn’t know what “right” felt like until now. The fit had an added bonus of helping me decide between a few bike brands I was debating between for my next tri ride. Very happy with my experience here.
— Kaitlyn Kinney, 28, triathlete
Thank you again for the time you spent getting me fit correctly a couple of weeks ago. The adjustments have worked like a charm. My saddle sores have all but subsided.
— Dave Lane, 45, recreational road cyclist
So I needed a road bike fit and started calling bike shops. Mitch picked up and worked me in the next day. The process, knowledge, and results were fantastic. In the end my bike is where I need it to be to prevent injury and go fast & efficient. It’s nice to deal with the owner with all those years of experience. It shows. The process was so easy for him but effective for me. I truly feel like I am on a different/better bike. Also, unlike other fits I have had, Mitch was never upselling me on a bunch of new stuff for my bike. Don’t go anywhere else!!!!!
— Grant Johnson, 35, recreational road cyclist
Had an awesome Retul bike fit from Mitch. The same day I completed my new bike fit, I went on a 3 hour ride and was 12 watts higher and my cadence increased by 10 RPM throughout the duration of the ride. This was on the same course, at the same heart rate, eating the same food as the previous week. I was honestly shocked and would be happy to share power files if you want to see proof. Thanks BioWheels!
— Kris Karwisch, 35, mountain biker
Got a fit by Mitch Graham at BioWheels last year and this helped increase my power and allowed me the comfortable training time necessary to win the Ault Park B Race Series with the support of Team Popsicle. Thanks Mitch!
— Rob Bruyer, 34, road racer
I went for a 20 mile ride yesterday. Wow! What a difference. My pedal stroke was so effortless! I have not been on the bike for a few weeks and the soreness that I usually have in my neck and back was not there. I usually have some minor chafing/friction as well. None of that was there. Amazing! Most noticeable was the inserts for the shoes. Kudos to you for your fitting process. Tom Carleton (fitness road rider)
