I’m a corona-rider who started biking regularly around late April. I am 5’8” with 31.5”-32” cycling inseam, riding a Lemond Tourmalet with 50cm c-t and 51cm top tube:


wife says I look like a circus bear on the bike. But here is the problem- I feel very stretched out on this bike. I feel like I need to move down to something like a 48 cm. The saddle is at maybe one hair behind KOPS position. The stem is about 70mm.
Since this pic was taken I moved the seat forward so that I am at about 0.75” ahead of KOPS - it feels much better but is it safe to be ahead of KOPS?

+10 for your wife!

I'd say you need at least a 56cm old school frame but more probably a 58 (not sure about modern sloped TT frames). From the photo, you look like your legs would always be tucked tight and would get very cramped.

You say you started in April but don't say how far you ride.

Are you physically uncomfortable? How do you feel after a long ride. I get being nervous about the position but are there any problems that can be tweaked? If you're reach is bothering you how about a slightly shorter stem?

Yea too small , reach short too for a road bike..

I used to be 5' 7", 31" cycling inseam, and a 50 CM Gitane was too small; I never measured the TT. A 54 CM was just right for me, and you have longer legs than I do.

I recommend seeing if you can get a test ride on a 54 or 56. You might feel better immediately. If you don't, you'll probably feel better once your body acclimates to the bigger size.

Too small imo.

Definitely too small. I agree with all above.

icemilkcoffee 

when you say legs would get cramped - do you mean the legs hitting the handlebar? It’s not close to hitting the bars though.

i guess the issue is that my neck gets tired from holding up my head. If I keep a flat or slightly arched back then the neck would feel better but there would be too much pressure on the perineum and it would go numb.

Everyone says the frame is too small but why do I feel the reach is so far away? A larger frame would put the reach even further away. Are you guys saying my hands should be even further out front?

Do a Google search for proper fit and I think you'll better understand. Perhaps the feeling of being too stretched out is just a lack of familiarity of road positions. Maybe you just prefer something more upright. I always reccomended a professional fit but, in this case, I don't think that will help.

@icemilkcoffee

It looks like you can't straighten your legs which means they are compressed and can't relax. Also, I just noticed you aren't even seated on the seat but almost behind it. Check out the other photo I randomly grabbed off the net and compare to your ride. perhaps it feels good to ride this way because you haven't tried a larger bike.

Please try and ride something a little larger and see what we mean.

The saddle height is adjusted such that my leg is straight when the peddle is lined up with the seat post, and roughly at KOPS position fore and aft. I am following all the usual guidelines. Including the one about riding with a 'flat back'. This is how the bike looks without me on it:

But I don't seem to see much guidelines about how far your hands should be in front of you. I have trouble envisioning how other 5'8" people are riding 55cm frames. Do you guys all have long arms or what?

I think you're on the borderline for going up one size and/or a slightly longer stem but its not that far out. You have a little bit of seatpost out on a horizontal top tube bike and a little bit of saddle to handlebar drop but its not that dramatic. Some racers would have similar fit except for having a longer stem.

How do you feel when you're in the drops?
A picture or 2 of you in the drops would be good. One with your legs at 9-3 and one with your legs at 6-12.

EDIT: A quick question. Does this bike have 700c wheels or 650c wheels? I'm not quite sure and if it does have 650c wheels then this would be why most people think that its FAR too small.

I’m not on the drops very often. When I am on the ends of the drops closest to my body it doesn’t feel too straining. But the drops behind the brake levers I don’t want to be on more than a minute or two at a time.

700c wheels

I'm 5'7" with your 31.5" cycling inseam, so very close to the same. Our shorter upper body means we need a taller bike for our legs, but with a shorter reach for our upper body. The problem with riding too small of a frame is when you adjust the saddle to the proper height, you end up with a huge saddle to bar drop, which many find uncomfortable.

I find 52-54 frames to fit the best depending on the bike, and always end up installing a shorter stem. Some frames even in this size range just won't work for me. (too long or too much s/b drop)

Try some larger frames, especially any with shorter top tube and reach specs. I think you'll be surprised.

OK. Road bikes are about having a low and streamlined riding position and your position in your photo is sitting up pretty high. I definitely wouldn't try to fit you to a smaller bike. You could fit on a one size larger bike yet you can make this bike fit as well.
I think your stem is too short and you could/should change the angle of the bars (bring the tops of the levers and the bottom of the drops closer to horizontal) or even try another set of bars altogether. It usually takes large hands to be really comfortable in the drops close to the levers.

There is an old rule of thumb that when you look down to the front hub the handlebars should be right in line between your eyes and the hub. Its only a rule of thumb yet your bars are WAY behind it and that is a short stem on your bike.

Another issue is centre of gravity on the bike. The bottom bracket (BB) is the centre of gravity on a bike. If you move the seat BACK, then its easier to reach forwards with less weight on your hands/arms/shoulders. I'd try to stretch yourself out both forwards and backwards to find/maintain a good balance on the bike.

Yes. your arms should form a 90° angle with your torso. It's a tiny bike for you. You feel that way because you're not used to riding a road bike. You'll get used to it.

I’m 5’3” and ride comfortably (and even stretched out depending on how far back I put my seat) with a 48cm top tube. I won’t belabour the point since it’s already been made, but wanted to give you an idea of the size of people who normally ride 48-50cm ish.
