Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

My turn for a fit thread

I was tooling around on the rollers this evening in a hotel room and didn't have much else to do, so I had kuf take some pics to see my new position. It was a little hard to tell from my race last weekend because there weren't any straight profile shots. My arms are apparently slightly longer than normal which partly accounts for my large drop (5"). They never seemed particularly long to me, I just measured my "wingspan" for another thread at about 71" from finger-tip to finger-tip. My shoulders are about 39cm, and I'm 5'9" overall and my inseam is about 32".

Not really looking for anything from the thread, just bored. Though I guess I am still trying to decide if I like the stem length. I can still feel the extra 1cm but I can't tell if I like it or not.

3-o-clock



leg extension



In the drops.



Note that the drops position is somewhat misleading, as I bend my elbows more when when I am actually riding and not focusing on not falling off the rollers, as shown here:



And for reference, the bike without me:

My two bobs worth is that you should try and decide which stem length you really like when out of the saddle in a full on sprint. I think that's the critical area. In the saddle its just different.

Your position looks good as ever.

Kuf also shot a video. This was only my second ride on rollers and I must admit I felt shakey and had to relearn it, but got comfortable much faster than the first time. These rollers are also narrower (the width and the diameter), and I was on my tricross last time which has a more relaxed geometry.

1) Wondering what size bike you ride, or Eff. top tube?
2) Wish I had tan lines this time of year.
3) Why are you in a hotel room?

1) 54cm "team" geometry tarmac SL2
2) although it snowed at today's race!
3) I'm between races in the San Diego area. Staying in a hotel near tomorrow's race. My wife stayed here today while I drove an hour each way...

I'm not an expert on bike fitting by any means but i have nearly the exact measurements as you. 5'9, long arms, ~32" inseam so i can relate. I got fitted by a local certified fitter i trust and my position ended up very close to yours. Stem slammed as low as possible, and my saddle was set far back so i have an identical 3 o'clock position as you.

Your arms look a little stretched on the hoods. I had the same situation so i swapped to a 90mm stem and I feel its more comfortable not having to stretch that far but still needing to bend low due to our massive drop.

I have my saddle forward, near the back of the saddle rails, with a non-setback post...

I can feel it when I am on the hoods, but not when I'm in the drops.

Everything looks fine, but you might want to think about getting rid of the curved back.

Oh, and the reason why you are a bit shaky on the rollers is because the front roller is too far forward. Stick a plumb bob on the front hub and the roller should be directly underneath or whatever is closest without going behind the bob. You'll be much more steady on the rollers.

I rode rollers for a year with them set up like you with the front roller too far forward thinking that I would "fall off" forward if the roller was further back. In truth, the forward rear roller is what keeps the bike from moving forward - the front roller is just to support the front wheel. The bike felt twitchy and not anything like the road; I thought that's just how rollers were. I read something here, checked the roller position with the plumb bob and moved the roller back one notch. Gravy. Just like riding on the road.

If you set the rollers up for your 'cross bike, keep in mind that the 'cross bike has a significantly longer wheelbase, so you'll need to reset your rollers for your road bike.

the cross bike was on different rollers. These I just got and that's how they were setup by the shop. I thought the roller was supposed to be ahead of the wheel so I left it. I'll move it back one and see how it goes. It was really just the first minute or so that it felt unstable and then I regained my confidence.

I'm pretty sure I don't ride on-road with my back arched like that, it was just a roller thing. I'll try to get a better profile at tomorrows race.

I run a slight setback seatpost on my TCR and have my Arione at the middle of the rails. Just took a look the the geometries of our bikes. You have a 73.5 seat tube angle and i have a 73 on my TCR which would account for your need for a non setback seatpost. Also, I notice you sit a little further back on your arione than I do (I can tell by how much "tail" is sticking out at the back.) So with this in mind, i think our saddle positions are roughly the same.

I also noticed your back is rolled a little. I was told by my fitter to keep a flat back.

BTW - here's how I look like on the drops with my back as flat as possible. My posture in general (sitting, standing) is good so it comes natural to me. This pic was taken with the 100mm stem.

I'm 30 not looking for advice... I was just bored. Since I'm not used to being on the rollers my position was not quite natural wrt my back. Same goes for where I sit on the saddle, when I am actually working, I sit more forward and have more "tail" showing

You guys are funny... I like my beard... Kuf requests that I shave the kissable areas so that's why it is shaped so. From whole foods we got dinner and food for today instead of eating out. I got a bunch of stuff from the salad bar (egg white salad and black bean salad) and sesame chicken and a califower cake from the deli case, sslmon avacado sushi roll, and some mocha Bon bons for desert. Kuf got lasagna from the deli case, a breakfast burrito for the morning, and a "strawberry shortcake" parfait for desert. The bagels I had brought with me...

Looks good, except for the chinstrap. Lose that and any fit issues will magically resolve themselves.

The rolled back thing was just a fluke of being on the rollers. Here is my natural position from yesterday...

Your saddle is too low. You also need to swap it out for one of these:


Also try lowering your stem and raising your bars.
