Tri & Road Bike Fitting Services

Whether you are just getting started, or you are a seasoned veteran, you can benefit from bike fit analysis.  Many athletes assume that a flat aero position is inherently uncomfortable, requires extreme flexibility and core strength, and is something only elite athletes can achieve.  This simply is NOT the case!  If you’ve had back or shoulder problems that you attribute to being too low or aggressive, it’s much more likely to be caused by a closed (too narrow) hip angle and/or a too short or too long cockpit/reach.  Without a biomechanical bike fit analysis, you are simply guessing.  We find again and again that our clients are MORE COMFORTABLE, MORE POWERFUL, and MORE AERO.

Nothing will do more for your speed than an optimal bike fit that gives you the “Big Three” of COMFORT, POWER and AERODYNAMICS.  But how do you know if YOUR bike fit is optimal?

Aero-position (triathlon) bike fit is totally different than standard road bike fit. Bike fit formulas based on static measures of body dimensions are not sufficient to find a good aero position.  Only body angle analysis can tell the whole story, and the best way to do that is to measure angles under load and in-motion, not in a static state.  We can make sure that your body is tracking through the same angles exhibited by the world’s top professionals.

We can help you get faster and more comfortable on your current bike, decide which new frame will work best for you, and help choose components and upgrades. 

The biggest performance upgrade you can make to your bike is a proper fit. Your bike and optimal fit coordinates must promote COMFORT, POWER and AERODYNAMICS.  A proper fit will help you be able to sustain your position for the duration or your event, promote maximum power output, and reduce aerodynamic drag.  The rider accounts for up to 80% of the aerodynamic drag created while cycling.  The bike frame, wheels, helmet, shoes, etc. accounts for only 20% of the resulting drag.  In short, an ideal aero position (horizontal torso) can save you 6 minutes over 40k, while aero wheels might save 1-2 minutes and an aero frame only 1 minute (note that these are not all additive).  Clearly, a good aero fit is the most cost-effective way to improve your bike split.

Now, you probably had some type of bike fit at the local bike shop when you bought your bike. If you ride a road bike in a standard road position, obtaining a halfway decent fit is relatively straight forward and might include inseam measurement, setting saddle height (using mathematical formula or measuring knee angle), etc.  This type of basic fit will generally work fine for a road position, and this is all most bike shops know how to do.  If you have not been fit to your tri bike by an aero fit specialist, you’re most likely set up wrong.  Also, a certificate from a 1 or 2 day bike fit class/seminar does not a fitter make.

The simple fact is this that aero fit is an involved, unique discipline and has nothing in common with a road bike fit.  Ideally, you want a fairly horizontal torso, which requires a lower front end.  Many people equate such a position with PAIN, which is not unexpected, as an aero position will be extremely uncomfortable unless done properly.  It really is possible to be aero, powerful, and comfortable, but you must examine and adjust every fit parameter.  To achieve a positive fit outcome, the position must be measured accurately, and static measuring devices don’t tell the whole story.

The TTBikeFit (aka, The Human Missile Factory) methodology utilized at The Energy Lab has the following advantages over a generic bike shop fit:

  • Aero-specific fit. We know how to fit aero. Many “fit systems” fail to distinguish between road and aero fitting.
  • We use dynamic analysis of you pedaling under load, as opposed to static measurement which may not accurately depict your position.
  • We use software to plot your angles while you are working, instead of measuring angles with a device while you are stopped. Angle measuring devices are prone to error and are unable to take measurements while you are moving.

While we can certainly fit you on your own bike, dynamic fit bike fittings have some major advantages.  They are great for finding a “perfect” position without being limited by a particular bike (frame size, geometry, crank length, aerobar, etc.).  If you have a bike that is wrong for you, or you are looking to move from an entry level to a high-end race bike, a fit bike session will take the guesswork out of the process. The revolutionary PATENTED Vertex Fit Cycle is simply the best fit bike available.  Because the Vertex Fit Cycle can remotely change all your fit parameters while you are pedaling under load, you can immediately feel the effect of changes, and we can immediately see (and analyze with motion analysis software) what the changes do to your body and pedal stroke.  We can incrementally and repeatedly adjust all your fit parameters until we zero in on that perfect fit.  We will also investigate crank length changes using the on-board Vari-Crank.  Proprietary calculators are then used to give you a list of frames that will work well for you.  Or, we can calculate exactly what adjustments are needed to match your current bike to the fit bike coordinates.  We also have proprietary calculators for configuring all the “Super Bikes”.  Since many of these are hugely painful and time consuming to adjust, it is great to know what needs to be done BEFORE wrenching.

If you’re considering a new bike, talk to us first! We are about fit first and UNBIASED advice.  Just ask anyone who has used our pre-buy services.  We can tell you what specific frames and sizes will work for you and discuss the pros and cons of just about anything out there.  Yes, we do sell bikes (Blue, Fuji, Kestrel, Argon 18, Louis Garneau, Ventum, Quintana Roo, Litespeed, Open, Orbea, Look, Premier) but we will ALWAYS provide you with a list of ALL bikes that could work for you, and we will NEVER recommend a bike that is wrong for you just to make a sale.  We have absolutely no floor inventory and therefore have no incentive to try to force you onto an ill-fitting bike because we need to make a sale.  It’s in your best interest to read this TTBikeFit Blog post BEFORE making a purchase decision.

TRIATHLETE MAGAZINE included Marc and The Energy Lab on their list of the BEST BIKE FITTERS IN THE US in a 2023 article.

From the article:

But pros aren’t the only ones who benefit from a proper bike fit. When age-groupers seek out a professional for a fitting, they often discover a wealth of information beyond the ideal saddle position. Stuart Selber, an age-grouper with ten Ironman finishes to his name, utilizes his fitter, Marc Galietta, to continually learn how to optimize his performance on the bike.

“Marc is an expert engineer with a full understanding of aerodynamics, bikes, and bodies and how they need to come together to produce an excellent ride or race,” Selber says. “But he also listens carefully, explains what he’s doing, and elicits and values feedback. In addition, he’s always available as a resource, answering questions and providing sound advice. Since I started working with Marc, my bike splits have improved by an order of magnitude, and I’ve been running better off the bike than ever before at the Ironman distance.”

Stuart’s full testimonial:

“I’ve been doing triathlons since the late 1980s, and have worked with many bike fitters. Marc Galietta is simply among the best in the business. He’s an expert engineer, of course, with a full understanding of aerodynamics, bikes, and bodies and how they need to come together to produce an excellent ride or race. But he also listens carefully, explains what he’s doing, and elicits and values feedback. In addition, he’s always available as a resource, answering questions and providing sound advice. Since I started working with Marc, my bike splits have improved by an order of magnitude, and I’ve been running better off the bike than ever before at the Ironman distance. One of the smartest things I’ve done in triathlon is to trust Marc with my bike fit. He’s a game changer!”

Stuart Selber

Faculty Adviser, Penn State Triathlon; 10x Ironman finisher

“Marc is phenomenal. Logical, practical in his approach. Explains everything along the way, making sure you understand the how’s and why’s. He listens and takes in all your concerns and what your aim is. His personal experience as a triathlete is remarkable and applies his experience well in helping you get the right fit. Not rushed at all. He was genuinely attentive and cared that he ‘got it right.’  Super nice and grateful for his time and attention. Went back for him to install some new components to help with my fit – was great he could do that since he had my fit measurements and could make sure it all still made sense for me, taking out any guessing. Can’t recommend him enough. Worth it many times over and I look forward to reaping the benefits of this fit. After just 2 weeks I’m already more comfortable in aero for almost the entirety of my training rides. Amazing.”

Eric Matkowski

“I can’t even express how much today means to me picking up this beauty and all the time and attention Marc gave me getting every little detail of the bike perfect. Also from my fit to full build was 16 days, that’s unreal!

Anyone ever looking for a bike fitting needs to go to him, he uses the Vertex, measures the angles, watch yourself ride live and takes time getting it all right and perfectly comfortable. I know I’ll be back as I prepare for the same first Ironman that Marc raced in Lake Placid! Thank you so much again, I can’t wait to get riding!”

Tina Claire

Philadelphia, PA

“Finding the right fit starts with the principle and integrity of the Fitter. Marc’s service and knowledge vastly improved my recovery and performance. Marc at the Energy Lab 100 percent delivers!”
Vedder Todd White

Buffalo, NY

“Three years ago , I had my first professional bike fit by Marc at The Energy Lab.  He not only selected and custom fit me to my first triathlon bike, but has since optimized my fit for maximum performance .  He gave me the confidence in my riding position which led to many overall age group wins.  I can’t thank  Marc enough for his fine attention to detail , professional manner, and expert knowledge!  I will be continually coming back to Marc for unbiased opinions, recommendations and updated fits!”
