i would be happy to help you find a new bike. but i’m going to give you a mild spanking first. not too hard. but, publicly. for all to see. as continuing education for everybody. here goes.
you do not have “retul measurements.” there’s not a single metric you listed that retul discovered, invented, developed. this is not to denigrate retul, which does a fine job at what it does. but these are not retul measurements. most of these metrics are going to come to you via a F.I.S.T. fit. and a GURU fit. but they are also not F.I.S.T. or GURU measurements. well, stack and reach are, and i suspect that most of the metics you list were first used in fit systems by us (F.I.S.T.). but i don’t claim them. they are just fit coordinates.
RETUL offers the following: a fit bike, a motion capture system, a school for fitters, and some software to help integrate it all.
GURU offers the following: a fit bike, a motion capture system, a school for fitters, and some software to help integrate it all.
Trek PrecisionFit offers the following: a fit bike, a motion capture system, a school for fitters, and some software to help integrate it all.
Shimano offers the following: a fit bike, a motion capture system, a school for fitters, and some software to help integrate it all.
the only proprietary brand here worth speaking of is the fitter. the fitter is the brand. the “brand” is either ready or unready to provide a true, quality dynamic fit depending on whether he has a fit bike. that fit bike can be an exit cycling bike, guru bike, retul bike, or purely custom bike. or shimano fit bike, altho i think those are not yet shipping. a “dynamic” fit (and a “retul fit” is a dynamic fit) is a fit that is executed while pedaling aboard a bike, so if that bike does not adjust quickly, and produce metrics, etc., it’s like saying you got a “dynamic” running shoe fitting, but were not allowed to do anything but stand still during the “dynamic” process. so, was your fit session executed aboard a fit bike? if not, then i question the validity of the output.
that said, the metrics you list are a top notch set. your fitter gave you top cabin metrics. rather than a set of retul metrics that are specific to retul’s motion capture system (it’s own version of body angles), which you can do absolutely nothing with, your fitter gave you metrics that you can actually use. that’s very helpful and good of your fitter to do, as far as that goes.
but let’s drill down on this. you said that you “took out a few spacers during the last fit.” i take that to mean this fit was executed on your existing bike, aboard a trainer, so, you got off the bike, sat around for 10 minutes while the spacers were taken out, got back on, and tried it. that’s a time interval that moves fro 10 minutes to 10 seconds (or fewer) with a proper fit bike.
now, you might say, “so what? how does that affect the quality of the end metrics?” it would not if the fit is being driven strictly by retul’s body angles. however, those angles sit inside a range. what determines where in the range? usually, it’s you. and it’s hard to know what you like better between one “trial” or “fit” and another if you have to wait minutes and minutes between each adjustment of the bike. this is why no true professional fitter using these newer post-F.I.S.T. protocols are without a fit bike. not everybody who’s got a fit bike is an experienced, serious, professional bike fitter. but every serious, professional bike fitter has a fit bike (or is soon to get one). it’s like hiring a professional wheel builder who has no truing stand. maybe he can build great custom wheels. but why would he not have a truing stand?
that mild spanking aside, here’s my concern: Saddle Setback- 36mm on a cobb saddle. unless it’s a new JOF cobb saddle, i question that metric. if that is truly where you want to sit, fine. if not, then that very choice, right there, reverberates through the entire fit, and outputs a bike wildly different than a bike you would have chosen had that metric been +10 or +15, or even more, which is more typical of a tri bike position of someone your height with a v flow max or plus. so, if that -36 is really, in my nomenclature, a +36, then we’re in business. and i can find that out pretty quickly just by reconstructing this position on one of my fit bikes and seeing if the metrics match.
but first, why don’t you tell me what cobb saddle it was?
