Jonathan Blyer is the aboriginal of a lot of fitters I’m activity to contour here, to appearance you what acceptable fitters attending like and, to the point, what acceptable applicable looks like in your area. Jon’s aggregation is alleged ACME Bicycle Aggregation and he and his business accomplice are in Brooklyn, NY.
I gave Jon and a few added fitters I adore some questions about their operations and again I gave them a warning: “You don’t accept my aftermost catechism yet. It’s a toughie. I’m activity to address your acknowledgment to our readers aloof as you address it to me.” This is array of a Bar Exam catechism for fitters, I explained. “You’re activity to attending competent, or out of your depth, in avant-garde of a few thousand readers. Are you abiding you appetite me to contour you?”
With Jon it was appealing easy. There is no catechism I could ask that he couldn’t acknowledgment at atomic as able-bodied as I could. Here’s an overview of his operation with FuBAR questions (Fitter Bar Exam questions) below.
History & Profile: ACME Bicycle Aggregation was founded in 2012 and Jon ran it by myself until a few years ago aback he brought in an agent who is now a business partner, Colin Tanner. (Jon is in the photo above. Colin is the guy who looks like a adolescent Viggo Mortensen in the photo below.) They accomplish about 400 fits a year. ACME acclimated to do about 70 percent triathlon fits but are now bottomward to about 30 percent tri fits with alley antagonism and alluvium authoritative up the balance. That’s a bazaar reality, not a about-face in absorption or focus.
They accept one area currently in a adjacency of Brooklyn alleged the Gowanus, and are “starting actively to anticipate about our aing steps,” which I booty to beggarly amplification of some sort.
Bike Sales: ACME sells bikes from Dimond, Moots, Parlee, Allied and DeRosa, and saddles from appealing abundant every saddle manufacturer.
Wrenching: ACME additionally offers automated service.
Education and Background: Jon has been an adviser both for GURU as able-bodied as F.I.S.T., that is, he has cogent accomplishments in training added fitters. He additionally holds certifications from Retül and is an IBFI akin 4 certified fitter. Colin holds certifications from Retul and Guru and is a USAC certified coach.
Tooling: – Fit Bike: ACME has both a Guru DFU 2.0 and a DFU 1.0.- Motion Capture: Retul with Retul V7 software; Guru’s Ambit of Right.- Quick Change Bench Clamp: A SwitchIt is assuredly army on the DFU 1.0 and they use a ancestor of the ACME Bench Cleat on the DFU 2.0 (this is Jon’s own bogus artefact that competes with the SwitchIt.)- Pedal/Shoe: Speedplay’s fit kit, a ample alternative of insoles and wedges.- Coffee: Quick Mill Silvano espresso apparatus with a bottomless bifold portafilter and a Mazzer mini grinder, “we alone serve the acceptable stuff.” (Bonus credibility for this.)
Other notable stuff: 60 canicule chargeless chase up for fits and 30 canicule money aback or barter on saddles. They do adaptable fits and bear custom-built bikes. Jon has aureate beyond the country to bear bikes, and will anon fly to the Average East to bear addition and to accomplish abiding it’s dialed in for the rider. (Can’t brainstorm who that adeptness be for!)
Fit Philosophy: Above, that’s the accessible stuff. Necessary! But easy. Now comes the adamantine stuff. I’m allurement every bigger in this alternation what “drives” the fit decisions the bigger makes. This requires a complete answer. “What causes you to change or adjudge on a specific fit coordinate?” No acknowledgment to this will suffice. Here’s what Jon wrote back:
”Our action on the DFU is actual abundant an avant-garde beginning action and we about chase the F.I.S.T. protocol. We alpha anniversary applicant off in a position that is appealing airy and we gradually assignment them into article a bit added achievement aggressive until we alpha to see them breaking bottomward in some way, again we aback off a little bit. An archetype of this would be our adjustment of award arm pad stack; we alpha off acutely too aerial and gradually lower the aerobars a few mms at a time (all while pedaling at a reasonable load, of course), anxiously watching and listening. Aback their anatomy starts to breach down, we accession the confined aback up a little bit. We administer agnate approaches to saddle height, cockpit ambit and weight administration / able bench angle.”
Okay, that’s what Jon wrote me. This is the aboriginal in a series, and I chose to activate with Jon because I accept complete aplomb in him as a bigger and as addition able to acknowledgment these questions. Also, I apprehend that Jon will advice me anatomy my questions bigger as this alternation progresses by his answers. What I was attractive for was article added blunt and concrete, as in: “I’m a Retül fitter, Retül’s accessible metric is anatomy angles, we move the saddle and the handlebars according to a aggregate of the fitter’s eye and the rider’s faculty of comfort, but consistently aural Retül’s angular ranges that accurate orthodoxy.” That answer, however, does not acknowledgment aerodynamics. Aback I contour Jim Manton at ERO I affiance aerodynamics will be a “driver” in his answer. Jon’s acknowledgment aloft is fine. And, he’s a retail bigger and I’m not. I accept the affluence of not seeing the problems he sees. Had I asked that catechism with added attention I’d accept gotten an acknowledgment with the attention I hoped from my ill-worded question.
Here was my boxy catechism for Jon: “I accept a Pad-center Y/X of 640mm and 505mm respectively. My saddle height, BB to saddle top, 4cm abaft the nose, is 785mm, and my breach adenoids saddle setback is -30mm (plumb band distance, aback from the BB). I ride 170mm cranks. I anticipate I appetite to jump on the disc anchor tri bike bandwagon. That’s all I’m activity to acquaint you unless you charge some abstracts allotment I haven’t anticipation to provide. I’d like 2 complete bike solutions from you. With diminutive detail. Extra acclaim if one of them is a bitter bike that doesn’t accept a proprietary prescriber.”
FuBAR Acknowledgment from Jon: “My best advancement based off of what you provided and because that I’m alone attractive at Disc Anchor Equipped Tri bikes would be a Cervelo P5X in a admeasurement large. The blueprint for the P5X uses the aback of the pad as the advertence point so I adapted your arm pad adeptness of 505mm to 460mm. [Jon provided a browse of the P5X Pad Stack/Reach prescriber which I’ve slotted in here, and I placed a red amphitheater cogent my position.]
“These coordinates acreage you in Medium, Ample or XL area but you accept the best jerk allowance in a admeasurement Ample for approaching adjustability. The XL would apparently ride a bit added abiding than the large, and you still accept a tiny bit of adaptability so that would be a application as able-bodied if you are a afraid bike addition and appetite a bike that adeptness ride a little beneath twitchy. I would alone appoint this if I was 99% assertive that your arm pads didn’t anytime accept to go added aback because there isn’t abundant allowance left.
“Here is the set up from the P5X online tool, there isn’t abundant added that I can add, they do a abundant job with this:
[Jon provided a browse of the P5X apparatus with the slider, that I haven’t apparent – appealing air-conditioned – that gives you a diminutive decree of the avant-garde end; that screenshot of it is aloof above, set to my measurements, with the decree delivered.]
“You accept addition acceptable option, save for possibly the arm pad amplitude spacing. That achievability is the new Cannondale Super Slice. I got the archive for this from Damon and Nathan and they are absorbed to this e mail in a chat document. [Which I got from Jon.]
“You would do able-bodied on a 56 with this bike from a pad stack/reach perspective. This bike is accessible with three altered axis lengths (60,90,120). You can additionally about-face the pads on this bike to change their fore/aft positioning. Note that alteration the axis breadth requires you to alter the hydraulic hoses and drain the system, authoritative a axis change absolutely an ordeal. I anticipate it took my artisan about 4 hours aback he’s done it. The extensions on this bike use a collet arrangement with the collet affirmed to the addendum and they are NOT accordant with any added 22.2 extensions, addition affair to consider. If they are cut too short, as we’ve seen, you are on the angle for accepting new extensions.
“Your set up on a admeasurement 56 would be with the 90mm axis with the pads in the aft position and 50mm of spacers amid the arm pads and the basebar. This puts you aural a few millimeters of your ambition numbers.
Jon additionally showed me how I’m a, “Ceepo Shadow R in a admeasurement Ample (Reach 435, Assemblage 540) with a Contour Design Aeria or Aeria Ultimate bar. The Aeria Ultimate bar has massive fore/aft adaptability but my algebraic is based on the aback of the pad actuality 60mm abaft the bar centermost which is almost in the average of the adjustable range. With this pad fore/aft position, you’ll charge a 90mm x -17 amount stem, a 10mm angle cap, no angle spacers aloft the cap and 10mm of spacer beneath the arm pads, putting the vertical ambit amid the pad and the bar centermost at 70mm. With this set up you should get your assemblage absolutely and the adeptness will alone be off by 4mms.”
The acknowledgment aloft is why Jon Blyer is the aboriginal bigger I’m advising in this series. What makes bike fit a science, rather than a atramentous art, is the adeptness to acknowledgment questions application algebraic aback algebraic beats intuition. Answering with specificity. What I acquisition with the best fitters is that I can accelerate you to any one of them and you’ll appear out with the aforementioned position and a agnate account of bikes that will bout the position the bigger placed you in.
And, yes, the solutions Jon recommended are absolutely the sizes I ride in anniversary bike with the complete configs on anniversary bike.
I’ll be “traveling” about the country, in a basic bout of fitters, city-by-city, and to added countries. Maybe I’ll mix in a little culture, Parts Unknown but we’ll be adequate bike fits instead of cuisine. You can apprehend added about ACME Bicycle Company.
