Trek Pilot Frame Size
 

I ride a 58 cm Trek Pilot 5.2 and am curious if the bike is the right size for me. I'm 6'1" w/ the following measurements as measured by my LBS using bikefitting.com:
Height: 180.5 cm
Inseam: 91 cm
Torso: 55.5 cm
Left Arm: 73 cm
Right Arm: 73 cm
Shoulder Width: 43 cm
Left Foot: 27.5 cm
Right Foot: 27.5 cm

The Pilot line goes from a 58 cm straight to a 63 cm. There's no 59 or 60 cm sizes.

Bigger question is how does it feel?

Feels pretty good so far, but the LBS didn't have a 63 cm to compare it to. I just want to make sure I didn't get a too small frame pushed on me just to make a sale.

Sydney is right at this point it is about how it feels to you. Try these online fit calculators for some piece of mind. (next time before you buy a bike)

You didn't give all the measurements they ask for you you'll have to measure yourself or better yet have someone do it for you. Good luck.

With those measurements, you appear to be long in the legs in proportion to your torso. I'm 6' with a 33.75 cycling inseam (86.5 cm) and my "big" bike is a 58. By adjusting the stem and saddle, it's set up to measure exactly the same as my other 3 bikes - a 57 Lemond, a 55 Lemond and a 56 Santana. I prefer the smaller frames for responsiveness and performance up to about 60 miles. Anything longer than that, and I want the comfort of the bigger frame.

So, the 58 probably fits just fine as a smaller, "race" style setup. But it may not be right for you if your goal is to do all day marathons.

As Sydney wrote - how does it feel?

I find Trek's sizing very frustrating, amongst other frustrations of the BIG manufacturers. I understand the rationale of reducing the number of sizes that dealers need to keep in inventory but I think the customer is at a loss when their sizing goes from 58 to 63cm.....not to mention no eyelets for fenders, and tire clearances that are ridiculous. Trek and Specialized finally acknowledged that not all riders want to ride with bars 4-6 inches below the level of the seat. I found what I needed in a custom bike for the cost of a Pilot or Roubaix. Rant over.

You and I are the same size at 6'1" and being long legged. The good news is the Pilot has a long steerer tube relative to top tube length so you will still get a good measure of handlebar height compared to how stretched out you are with your proportionately std. size torso. In effect that bike will ride for you more like a bigger std frame Trek 5000 except it will have a bit shorter reach...not a bad thing for your proportion. If I were buying a Trek Pilot, I may very well choose the same frame size and I prefer a big bike...I ride a 61cm c-t-t mildly sloped top tube Bianchi. With your torso length you would likely feel too stretched out on a 63cm Pilot.
Hope that gives you some peace of mind.

i agrree but at least they give you an actual size as opposed to S M L XL

S M L XL come with geometry charts,so there goes the mystery.

Seems like 58 cm is probably the right size for me in the Pilot. I looked at Giant's compact geometry sizes, and they only go up to a 58.5 cm frame which is listed as an extra large. In fact, the largest Giant goes is 59.5 cm in the TCR Composite. Anyhow, my handlebar height is only 1/8 to 1/4 inches lower than my saddle, so I'm still pretty upright on this frame. I agree that the 63 cm would probably stretch me out too much seeing that my torso is shorter than average for my height. Thanks to all for the advice and encouragement. This sizing thing is far from an exact science as I can see.

Anybody feel a 6'5" rider (w/37" inseam) should be looking at anything other than a 63cm Pilot? I ran the idea past a couple others and they feel the 58 would be to small. (I did not test ride a 58 yet.)

I currently have an Giant OCR (size XL) that I'm replacing and it does feel small. I bought the Giant without trying the XL size since the LBS didn't have an XL in stock. I'm now having the same problem finding a 63cm Pilot to test. :(

I do think the 63 would be a better fit, but you should ride one first regardless.

Just took delivery of a Project One 58cm Pilot. I'm 6' 1", mostly legs and arms, with a very short torso. Very, very few stock frames fit my dimensions, but the Pilot comes close. The toptube measurement had to be short enough, and the headtube needed to be long for me. Even the 176mm Pilot headtube is a bit on the short side, as I kept a fair amount of spacers on steerer. A very nice bike and I do not feel a drop in performance compared to my Klein Q-Pro XX. Certainly more comfortable. Bottom line, if your body has some out of proportion measurements, custom is the answer. Sometimes a stock frame cannot be dialed in no matter what components are swapped. If you are short in the torso, have to believe 58 is good for you. BTW, what is your saddle to bar top drop?

Saddle top to bar top on my OCR is 28cm. My torso length is *about* 67cm. Not sure if that's about average or on the long side.
