Howdy,

Big news — we’re officially rockin’ and rollin’ in Corinth, Texas! 🎉

We made the move in mid‑November and have been full‑speed ahead ever since. Right now we’re booking about 2–3 weeks out, with March openings up for grabs.

And to everyone gearing up for the Little Elm Ironman in March — go crush it! 💪🔥 You’ve got this.

Dynamic Bike Fit is Open For Fitting in Roanoke, Texas

DBF will continue providing state of the art bike fitting services in North Texas. While Mad Duck Roanoke (bike shop) closed this past week, Dynamic Bike Fit continues to provide independent fitting services. Moving forward, I will be performing fits at our Roanoke studio on select days. If you are in need of services outside of published times, please reach out. We can see what we can make happen.

Online Scheduling:

12/01/2024

I want to address and clear up any rumors and misinformation floating around town.

First and foremost...DYNAMIC BIKE FIT IS NOT CLOSING.

Mark, owner of Mad Duck Roanoke and independent of DBF, will be retiring from the bike industry at the end of the year. He will close the Roanoke bike shop later this month. While it may be enticing for some to take over a bike shop, I have no desire nor time to run the day to day activities of a local bike shop.

Dynamic Bike Fit will remain an independent cycling services company focused on providing bike fit services in a judgement free environment open to all levels of cyclists from serious recreational to competitive road and triathlon.

Since 2009, I have remained an independent Master Retul Fitter rooted in science and not in myth and hearsay. As such, I am free from bicycle brand constraints and void of demands to sell and service bikes. My focus has always been and will continue to be on you, the rider.

Whether you bought your bike from a fine local bike shop, snagged an online ride, or secured a used bike, DBF will continue to work with you to fit your unique requirements. Where you buy and service your bike has no bearing on the advanced fitting services Dynamic Bike Fit provides.

Finally...looking to the future:

December 2024
- Begin offering new time slots to better align with rider's work schedules.
- Support and assist Mark in activities related to closing Mad Duck Roanoke.

March 2025
- Move to a new location in the vicinity of Roanoke, TX that is better sized for the services DBF provides

Thank you,

Howdy,

NEEDED - SRAM BLIP BOX

Does anyone have a SRAM eTAP blip box that they would be able to loan for a few weeks? I know some of ya'll have TT bikes that sit until a TT while others have Tri bikes that may be dormant for a few weeks. Its a long story but I have a client who is in great need for that part to be able to get their rig back rolling before a big event later this month.

Please let me know if you can accommodate.

Thank you
Craig Fulk

UPDATE: THANK YOU FOR HELPING TO MAKE IT HAPPEN.
Our little community here pulled through and helped to make Trent Fielder trip to world championships in Australia happen.

I am seeking some help for a para-athlete I have been working with... Does anyone have a bike case like the ones pictured below and would be willing to loan it for a short period of time? This athlete is in need of one to get to Triathlon World Championships in Australia. The airlines and shipping companies have been less than accommodating. However, these cases may accommodate his hand-cycle and allow it to go on the plane at a reasonable cost.

Let me know....THANK YOU!

Howdy,

I am about to wrap up my dissertation and need some help!!! I am asking for about 3-5 minutes of your time to answer a really quick survey on your cycling participation.

Examining Post-Covid Cycling Participation

We are interested in your cycling experiences…

Now that we are past the COVID-19 pandemic, we find it essential to examine the role of technological innovation on cycling participation. Presently, there is a gap in our understanding of what drives traditional sports participants to engage in technology-driven forms of sport and exercise.

You will be asked to complete a single online anonymous survey that is expected to take less than 5 minutes to complete. The survey includes questions related to your participation in the sport of cycling.

Thank you for your time.
