Do any of you upsize your frames?

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

Anyone here ride frames that are intentionally larger than your "prescribed" frame size? Just curious.

I did. I have short legs/long torso. A correctly sized bike inevitably has a top tube 2cm too short, even with a 12cm stem. I went with a 53cm PF and the first thing everybody says is your saddle is too low, as if I didn't measure that already. My saddle is 2-4cm lower than other guys my height because of my dimensions.

They want a longer top tube, so they can get lower?

Top tube is more important than seat tube, and so you are actually riding the right size then.

My Fuji is a tad big on me. Course, the next size down was almost too small so I went big instead of small.

I used to, but then tried the "presribed size" and wish I hadn't. I also have a long torso, and now have my seat sitting so far back I go through 3 rear tires in the time I go through one front.

+1.



This is a 58cm and while a 56cm would have looked like a "more normal" fit, the TT was simply too short on the 56cm frame.

i have the same issue, my trunk is longer than my legs. Felt provided my solution. i went to try one out and asked for a 58 because that's what other bikes i've ridden were sized and ended up with a 56 that fits me perfectly.

Yes, unintentionally back in 1993 when I picked up my 1992 Trek 5200. It is a 54cm and my inseam (actual) is only 28.5". So, technically, I fit better on a 52 or 53cm ... and maybe a 51cm on some frames. But, I rode the 54cm 5200 till last year full-time. I now have a 53cm Cannondale which does fit a bit better. I tried the 52cm several times, but was simply too use to the larger frame.

I would love to get a custom carbon fiber frame next. I need to understand a bit more about handling before I go custom again.

My first compact was too small so I got upsized. That was too big so I went for more traditional geometry and got the perfect fit.

MIN, that looks like the setup of my bike. about 1.5 inches of saddle-bar drop with a 110 mm stem and my seat is positioned on the rails a couple cm back from center.

I'm 5'4" with a 29 inch inseam. I've been told that I should ride a 49 for that racier position, but I'm on a 51 and fairly comfortable on that. Longish torso, short legs.

I'm glad to see that I'm not the only one here.

I road smaller then went too big. Now it is just right.

If you move your seat waaaay back to stretch out then isn't the knee getting too far back?
Shouldn't the stem be reeeeeal long?

I have the same issue, if you can't go custom, look for Lemonds or pre-cf Kleins. Heck, if you find a CF Klein in the USA, let me know!

Back in the old days when even the best seatpost would bend or break if extended more than a couple of inches every one rode frames that today would be considered too large. My long gone mentor would say that when standing over the top tube didn't hurt it was too small! Look at photos of 70's and earlier era bikes and there riders and you will see what I'm talking about. Being over 50 I still use frames considered too large by modern standards but I can stand over my bikes top tube and not squeeze any tender parts. My old mentor would laugh at me for even that! He would say bikes are for riding and not for standing over. I do like stretching out over a long top tube.

I just got a 58 even though I should be riding a 60 based on my overall height. I have a short torso, so I didn't want to feel too stretched out. Unfortunately, raising the saddle to the proper height creates a lot of saddle-to-bar drop, so I have to leave my stem flipped up.

Interesting...When I went shopping a few months ago the local Trek dealer insisted that I was a 56 (yes they had 54s) and it felt okay. The Trek 54 was noticably small. I tried a Felt and the LBS said I was at the high end of a 54 and it felt great. I guess that the sizes from company to company really vary so riding the bike is more important than simply sticking to a number.

2.5" saddle to bar drop for me. Seat tube is 58cm c-t and 56cm c-c.
I am 5"10.5" with a 32.25" inseam. Since the photo I have moved the saddle backwards a bit.

^ 110mm Ritchey WCS.

Proportions look funny in the photo because the perspective is from the bottom up. No else has ever mentioned that it looks too big on me, etc. When I rewarpped the bar, I rotated the bar down as well, per the FSA installation guidelines. The install was jack-up from the factory.
