critique my 70.3 switzerland (gravel!) bike setup
Quote | Reply
ok folks:
the story is that i'm getting a new tri bike this summer in canada. meanwhile i'm here in zurich and signed up for 70.3 switzerland on a bit of a whim. the best bike i have currently available is my gravel bike, so i've tried to make it work. your thoughts on my setup/position:

-scott addict gravel, w/ clip-ons
-fulcrum 40 wheels w/ 30mm gp tires
-castelli san remo suit
-specialized evade helmet
-silca socks
-bont tr-1 shoes
-i've fit a tube, levers, tool, and CO2 in that bento box, and there should be room left for gels and gummies. so, no saddlebag needed.
-have a home-made BTA bottle (zip ties!) that i'll replace with hand-ups on course, and a 500mL aero bottle on the frame. (2x bike bottles and 1 aero bottle would be 2.25 litres during the ride, which feels about right.)

i've ridden some in this position and it feels good, including a long ride with 2x30mins at race-ish power.

IMO it’s OK, non-distinguishable from a road bike with clip-ons.

T1/T2 is on a grass field. If you intend to put cycling shoes on and run in them, fine. Otherwise, I wouldn’t like to run in socks on this muddy grass. Not sure if you then change socks for the run.

Your saddle looks too high (not pink).

If that position is comfortable enough you can hold it for two plus hours, the bike will not be slowing you down much at all. Agree it does look like your leg is extended a bit too much when at the bottom of the pedal stroke. Maybe that is because you are trying to prop yourself up on the wall, but your saddle might be a touch on the high side.

What clip-ons are those?

those are an aliexpress special: a cool $11 and they're yours:

honestly, they've been good for the price. initially i bought them because i wanted some aerobars on my trainer bike, but i was happy enough with them and decided to slap them on my bikes for a few races. i think i've raced them four times now? the only 'problem' (which could be user error) is that a couple of times now i've had the extensions come loose during races. maybe i didn't pay close enough attention to torque when swapping them between bikes?

The saddle isn't too high. The cranks are too long.

While he looks too stretched out that bottom of the stroke, he also looks crunched at the top of the stroke. Saddle height could move down a touch, but likely not enough to make a difference.

thanks all -
-cranks are 172.5. i'm 183cm tall (exactly 6'0", i think), with fairly normal proportions (although a fitter once told me i was a bit long-limbed).
-it's true that in the image i'm resting on my left shoulder at just a little bit of an angle, so i'm leaning slightly away from the camera. does that have the effect of 'stretching out' my right leg? maybe.
-i do have very, very tight hamstrings (always have) and though i'm working on it, it does often make for lower-back pain off the bike. my last long ride in this position (aerobars and all) i did a bit over an hour in aero position. off the bike (slow transition in my house) i had probably a few steps of walking, lunges, etc., 60-90 seconds of quite ginger running, and then was at full pace within one km. after that i ran race pace for ~10k comfortably enough.
-so in terms of saddle height, i could probably drop it a few mm but somehow feel i wouldn't want to go too much lower.

For a road bike, 172.5 isn't all that long. I'm 5'10" and ride 170s. On my tri bike though, I run 155s. That's a downside of swiss-army knife bike (pun intended). It's not going to be perfect, whatever that is, but it will be functional. If you can run afterwards and it doesn't hurt, I say go with it.

Tight hamstrings would be more evidence your saddle is too high. Although your cockpit doesn't seem too much lower than your saddle relative to what others ride.

i did a guru fit last year and one of the things we experimented with was crank length. definitely i felt good riding shorter, but one thing the fitter emphasized was his belief that you should run the same crank length on all your bikes.
thoughts on that?

Absolutely not. Triathlon is a different sport to cycling.
It's like saying you should use the same pedals and Q factor across all the bikes to make it the same. Great until you have to use road pedals on your mtb and then you are trying to narrow the Q factor on your MTB to make it match your Tri bike.

It could be worth it if you are a pro/highly competitive athlete but then you would just train more on your race bike (or set up two identical race position bikes).

yeah, i have to say - short cranks did feel nice. but as someone who rides (and races!) tri, 'cross, gravel, MTB, and road . . . i can only afford so many cranksets!

Different horses for different courses. I don't want the fit to be the same on the road bike as my tri bike, so the frame geometry and crank length and stem and handlebars are all different.

i should say that it's not that my hamstrings are tight specifically when riding. it's that they've been tight my whole life. i've been a far cry from touching my toes since i was a kid.
