Does this bike fit? (Part 2)

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

Does this bike fit? (Part 2)

After following some suggestions I received in my first thread about my bike fit, I made the following adjustments:

1) Raised and leveled the saddle
2) Slid the saddle back in accordance with "Knee Over Pedal Spindle"
3) Rotated the handle bars forward so that the bottoms of the hoods are essentially parallel to the ground.
4) Rotated the shifters inward slightly so they conform to the natural angle of the wrists.
5) Flipped the 7-degree 100 mm stem to effectively lower the handle bars.

When I first get on the bike, everything feels right. After a few miles however, I do still feel like I am reaching for the hoods, rather than just gripping them naturally. I don't have any pain or discomfort, just the sensation that I am "reaching". Either the reach is too long, or it's all in my head and I'm just need to get used to the right position. Any thoughts?

Here's two more pictures, and a video clip that I uploaded to Youtube. In the video, the first two passes are on the hoods, the second two the drops.

The fit looks Ok (from the vid). Your shoulders look tense. Try and relax more when you ride. That could explain why the discomfort after a few minutes.

BTW, this is what I noticed from the video. Your riding style could be very relaxed when you're not riding in circles on your street.

your saddle is too low. where did you buy this bike and why didnt they fit you? and secondly all the adjustments you did essentially made the front end a bit longer of a reach so it is probably true that you feel stretched out, but by eyeballing it if you are feeling comfortable...and im guessing you havent ridden the bike a ton, i would go with it for a while.

From the video, it looks like your legs are splaying out instead of running more parallel to the bike. This could be causing you discomfort as well

Judging by the video, it looks like your saddle is too low and you're a little stretched out (probably your stem is too long).

Your saddle needs to come up at least a centimeter and probably two. You may feel like you are not reaching as much if you bring it up to the right height. Keep in mind when you bring it up a centimeter or more, you may need to move the saddle forward a little.

^ +1 -also, relax shoulders, flatten back, bring knees/thighs in parallel to the top tube.

The guy at the LBS said he thought the bike fit me. He was so sure that he didn't have me try a smaller one. I'm 5' 10.5" and he sold me a 58 cm Trek 1.2. This same shop also sold my wife a bike that was about 3 sizes too big for her because it was the only one they had in stock. So I don't trust the fit they did for me.

I'm 6'2" and I ride a 58. I have shorter legs though, 32" inseam, and a longer torso. I really don't think your bike is too big for you based on the video. I think your seat needs to come up and you should probably flip the stem back over to bring the bars back up. Bringing them down will make the reach longer. the bars themselves look to be where they should be rotation wise, your levers look to be in a good position.

My experience with bike shops thus far has been to stick with the ones who take the time to get you the right bike for you and not just try to get you on which ever bike they need to clear out. When I went shopping for the bike I bought a few months ago I experienced quite a bit of the latter but was lucky to find one which was also interested in making sure I was comfortable. If this is your first bike and you haven't spent much time riding then give the current set up some time, and if it still feels uncomfortable then get a pro fit from someone who knows what they're doing.

im about your size and by the looks of things i have a similar build, im am kind of right in the middle of a 56 and a 58 so i mean you can def. make the 58 work, the stem on that i would imagine is a 110, go ask for a 100mm and try that, if that is still too long try a 90 make sure they swap them out for you and do not charge you a penny, and after that fiasco, start going to a different shop.

I,m 5'10.5 and picked up a 54 cm Trek 2.1 back in April. The fit was great. I have since picked up a KHS Team carbon with full Dura Ace that also fits great and what a difference between the two. My new bike is like riding on glass.

I actually think the stem that came with the bike is a 100. I thought about trying a 90mm but I am concerned that may hurt the handling. Does anyone have any experience with a 90mm stem on these or similar bikes?

I agree, the seat still feels a little low and the next thing I do will be to raise it. Aside from that, how does the reach and the "cockpit" look?

90 is OK IMO. 58 is a big bike for 5'10", but maybe it works for you. I'm 6' and ride 56, but I don't have any Treks, and I've got short arms. From the above pictures it looks like the reach is too much, and the saddle is too low.

OP...you have the reach of a top racer. It wouldn't work for me and not too well for the average cyclist. You have many options. You can raise your handlebars or shorten the stem if you want to maintain that level of seat set back. You can check yourself with a camera. When riding on the hoods with slightly bent elbows, you want about a 45-50 deg. back angle.
Position is largely a measure of choice and fitness. If you are in racing shape you can tolerate your position but it frankly would hurt my nuts and put too much pressure on my hands.
Trial and error by riding is the best teacher but to my eye you are too stretched out.
HTH.

From the video, it seemed your saddle was half an inch or an inch too low. You could relax your arms a bit more.

Although pro racers have all sorts of scientific methods to judge whether the saddle should be moved closer to the stem or further from the stem, many simply place the saddle where it is most comfortable for their style of riding. Greg LeMond often had his saddles pushed as far back as they could go, and many sprinters have their saddles pushed forward.

I would put the saddle at the "dead middle" of its rails, and raise the saddle one inch. Then ride for a week or so. At that point, if I felt too stretched out, I'd move the saddle forward. If I felt too bunched up, I would move the saddle back.

Setting the saddle position by "comfort" is the sensible thing for recreational cyclists to do. But, many "Lance A-Likes" prefer to use some "scientific formula", no matter how painful the results.

Doesn't my first picture look like about that back angle?

Does anyone think my handling will suffer if I try a 90 mm stem? A 90 mm stem should give me about the same reach as the next size smaller bike. Basically, I'm at the point where I need to decide if I want to go through the hassle of trying to convince the LBS to exchange my bike for a smaller one, or make this one work.

its not going to have any real ill effects especially with the way you are on the bike currently. swap it out is my vote.

..and my next question....does 1 cm change in stem length really make a noticeable difference?

Yes you will notice it. Where you will really notice a short stem is when you are out of the saddle. I'm sure you can make this frame work ok with a sufficiently short stem but in doing so you are making compromises. If it were me and I had the option I would swap this bike out for something on which you can achieve something closer to ideal fit. You look too long in that pic of you on the hoods. I have found that smaller frames handle better in and out of the saddle and are just more fun to ride. The challenge with smaller frames is avoiding excessive saddle to bar drop. The 56 is has a top tube that is 1.5 cm shorter than that 58 but part of that is due to the 58's slacker seat tube (73.6 vs 73.1). The 56 has head tube that is 2 cm shorter so to get the same saddle to bar drop as you presently have you would need to add 2cm of spacers.

Looks like you wont have much seat post exposed, even when you raise the saddle up a bit to proper height. A smaller frame will have the shorter top tube that you seem to need, and since you have a ton of seat post to go, I think smaller is better for you.

That bike store is not looking out for you or your wife's best interests!
