I know, I know, another cross sizing thread. I'll try to make mine a little different. I recently purchased a Pinarello Cross. The overall fit when riding is great, but when straddling the bar, I can only pick the bike up maybe an inch or so before contact with my fellas. I went through a professional fitting process, etc.. before buying it, but it seems a touch big by the "over the bar" standard. Should I worry more about the riding position sizing, or where the bar meets my body? The shop where I purchased it told me that the next size down would be too small, as the bars would be too low. Does this make sense?

Thanks in advance... :beer:

Do you ever straddle the bar when riding ?

Just checked my Tricross, I get about 1 inch, maybe 1.5, of clearance. I'd focus on this sentence:


The overall fit when riding is great

when straddling the bar, I can only pick the bike up maybe an inch or so before contact with my fellas. Much too large a frame. You'll want at least three inches clearance, to get momentum going before racking your pea-sized balls.

:lol: I'll just ride it and shut up. Thanks for all the input guys.

Over the bar sizing is, no longer a valid method of gauging bike size, due to the changes in bike geometries, sloping top tubes, etc.
As long as it is comfortable while riding, you are golden.

I suffer the East Asian affliction of having short legs and long torso.
My ping pongs are always hitting the net. I have about ZERO clearance on all my bikes because I optimize fit for the top tube (traditional geometry).

This has only been a weakness in 'cross, where sometimes I wish I could dab a foot down as easily as some of the other guys, especially on off-camber hairpins. But that really means I should just work on my bike handling more.

It's just remarkable tho, how many shops still use this method. I went to one shop who told me I was a 55cm Felt, because I was not touching. That would have been WAY too big for me. This has been a great learning lesson for me, as I have not bought a bike since I was in college (16 years ago).

I wouldn't worry about any "rules" on sizing these days. Compact frames and individual preference has made the old thinking outdated. I have about an inch clearance over my Tricross and I couldn't be more please with comfort and ride (5'10" / 56cm). I tried a 54cm and it felt like a kid's bike. The key for me was leg length stretch to the pedal. Feeling cramped on a bike is truly miserable, so better to err on the side of slightly oversize in my opinion.

Chulo, How do you like your Pinarello? Where do you ride it?

I have read in reviews that there has been some problem with juddering forks when braking at speed - any experience of this?

I do most of my riding on the Fox River trails, which is close to my office in the NW Burbs. I can easily get to it, and its relatively scenic, and safe.

It's a great bike. Fast, durable, and easy to spend time on. My usual ride on it is ~25 miles, so I can't say I've done a long ride, but for how I figured I would use it, its great.

If you had a pro fit you should be fine. I guess the question is what did they do to fit you? Usually it's going to require measuring your in seam, arm length, stuff like that and setting up on a trainer to measure angles and what not.

Was it like that? If so no worries.

Typically the TT measurement is the most important on a bike and most people prefer to have a shorter TT or at least a shorter stem then there road fit, less saddle to bar drop(higher bars), and some like to have the saddle a bit lower.
