As we strive to be better cyclists we often forget about the obvious, our position on the bike. We spend countless hours inside riding Zwift and Trainer Road, and outside training for races, Fondo's, century rides and triathlons but spend no time on our position, and then assume that we are riding efficiently. Sound about right? So now what? Yup, you need to get a bike fit, but there are so many fitters now, where do you go and who can you trust?

Well, to be quite honest, there is no one perfect fit methodology but there are a few that are very close! We believe that there is nothing currently more accurate than dynamic fitting. Why? Simple, we want to know what your body is doing while your pedaling under load. A static fit, one where you are measured in a stationary position with a fitter manipulating your appendages is simply a close guess at best.

But first, you need to know that the most important thing about bike fit is: it starts with the body and ends with the body. So that is where we begin and that is where we spend a lot of time. Nearly everyone has some kind of physical issue; be it high arches, a sore back or a full hip or limb replacement. Every little bit matters. Understanding the body and what it is telling us is the most important part of the fit so we even offer a medical fitting that gives you the option to have a Physical Therapist work alongside you during your session. If your body can not maintain the position for the duration of your ride, then we have more work to do. 

Your comfort and efficiency is our priority and we take it very seriously. In order to earn and keep your trust, we have learned from and partnered with the best fitters in the world and then compiled the best of the best and made it available to you. We combine SBCU Retül Fit physical assessment to determine what makes you unique and Retül Fit fitting methodology for precise positioning. Then ALL of our equipment is 100% dynamic, meaning ALL of our fitting services are done with the rider in motion, without exception. You expect the best, and that is what we offer. 

Be prepared to be involved and educated on the wonder of bike fitting!


Fitting is our passion at Parvilla Custom f i t, it is in our soul and it is what we love to do. In our quest to find the perfect position for each of our customer’s individual needs, we have invested in the absolute best technology in the world. In 2011 we were the first studio in the Mid-Atlantic to invest in a computer controlled fit bike. In 2012, we were first again when we combined our Guru Legacy DFU with Retül’s 3D Motion Capture System and began to set the pace in Dynamic fitting. In 2013 we were the first studio in the country to upgrade our hardware to Retül’s new "Vantage 7" system. 2014 saw the introduction of PARVILLA CUSTOM Fütbeds by Retül. In late 2015 we added GebioMized saddle pressure analysis and introduced a Medical Fit option, working with a registered PT right in the studio. Early 2017 saw a complete remodel of the original Edgewater studio and an upgrade of our Legacy DFU to a new Gen 2.0 DFU. The upgrade made us the only fit studio in the USA at the time that combined the most advanced computer controlled fit bike with Retül and GebioMized that rotated 360 degrees in order to accurately capture both sides of the body. In the fall of 2017, we designed, built and opened a gorgeous new fit studio at Parvilla's new location in January 2018! In January 2019 updated Parvilla Custom f i t to Parvilla Custom Sports Performance and introduce Athlete Testing services in our NEW Sports Performance Lab. In early spring of 2020, we introduced a Metabolic Fit Service that allows positional validation using our V02 testing equipment. This is a must for the competitive triathlete and roadie looking for that extra power savings. 

Spring of 2021 we introduced Retül Premium Fit

We are one of the first fit studio's in the USA to offer Retül's NEW GOLD standard fit service

f i t Partners

SPECIALIZED - SBCU - Industry leader, SBCU is the only bike fit methodology that's ergonomically designed and scientifically tested to improve power, endurance, and comfort. Created by Dr. Andy Pruitt, SBCU brought bike fit into the modern age in thousands of bicycle retailers world-wide. The constant push for excellence in physical assessment protocol, basic through advanced fit methodology and the acquisition of Retül 3D Motion Capture technology has made it the gold standard in fit technology.

SPECIALIZED - Retül - Industry leader, Retül 3D Motion Capture technology, simultaneously measures three planes of movement on the rider while pedaling. Retül averages the rider's body movement to provide a comprehensive data set reflecting the rider's position. Only at this point can a bike fit expert properly evaluate changes to a rider's position. Attempts to analyze the rider in a static position will not provide data at the same level of accuracy as 3D motion capture. Based in Boulder, Colorado, Retül has specialized in bike fit technology and training since 2007. The company was acquired by Specialized Bicycles in 2012 and now exclusively provides fit technology for Specialized dealers.

GURU Cycling - Industry leader, the Guru Dynamic Fit Unit (DFU) revolutionized the fit process in 2010 by drastically increasing efficiency and comfort and by creating an interactive experience for the rider. The original Legacy DFU was the first computer-automated bicycle fitting system in the world that allowed cyclists to feel nuanced differences in multiple riding positions while pedaling. The state-of-the-art, computer-controlled GURU DFU Generation 2.0 adjusts your riding position in real-time to maximize your comfort and efficiency. Incline/decline adjustment allows you to test riding positions while ascending or descending to simulate riding conditions. 

GebioMizedIndustry leader in Cycling pressure analysis tools. Pressure analysis is available for all bicycle contact points including Saddle, Shoe, Aerobar, and Grip or handlebar. This state of the art pressure and force measurement technology was developed in Munster, Germany. GebioMized saddle mapping technology gives the client the ability to visualize the saddle and body interface in real-time, it opens the door to understanding pressure distribution of different saddle positions and/or comparison of different saddle types when combined with fitting process.
