|Hey I am 5' 8'' and ride a 58cm 2001 Trek 5200. I hear a lot of you guys say you're my height but yet you ride a 54cm! Do I just have wierd proportions?
BTW: my inseam is 31.5" ,I have a a 250mm seatpost maxed out, and yes I am fitted right.

|Curnching the dirty numbers through the standard fit formulas says you should be on a 54ish frame (depending on how it's measured).
Are you sure it's a 58???

|I am 5'9" and have a longish (for my height) inseam of 33" and I ride a 54 c to c Serotta with a 55.5 top tube. Are you sure your inseam is only 31.5" as described in "fit your bike like a pro" at coloradocyclist.com? Anyway, it sounds large to me, but if you are mostly pleasure riding and touring it probably is alright.|
|Grant Peterson would say it's too small||gtx|

|but most people would say it's one or two sizes too big. But if you're happy, you're happy.|

|i "may" buy a coppi from gvh...a 54, neuron. the seat angle is 74 and tt is 54.5. my short legs will be happy on a steeper seat angle..steel lugged fork. |
what do you think? i'd build it wiht an old ugly 105 group (plus old, heavy and nice dura ace hubs) that hang on my present frame.

|sounds good to me if you think it will fit. The Coppis I have seen have looked pretty nice. Glad to hear you're getting so into road riding.|

|If you are in a proper riding position (hips not rocking when pedaling backward is one way to determine this, knee at a slight angle at the bottom of the stroke is another) and your seat post is max'd, then you obviously can't use a smaller frame. Check out some/all of these web sites for sizing guidance. They'll be a lot more use to you than just throwing out some numbers like you've done.

|I'm 6' with 35" inseam and ride a 58CM Trek 5200 OCLV.|
Nov 23, 2001 5:56 PM
|Are you sure your frame is a 58cm CT??? Your #'s just don't add up. Maxed out seat post with a 58cm frame and 31.5" inseam..... ????
I'm 5' 8" with a 31.75" inseam and I fit perfect on 54-55cm CT frames. I can't imagine that you could fit a 58cm TREK.
Nov 23, 2001 6:12 PM
|Well, its closer to 32", but yeah it is a 58cm frame. It fits good and I have a slight bend in my knee with about 6" of seatpost showing(measured from top of collar to bottom of clamp.)|
Nov 23, 2001 8:03 PM
|My brother's 58cm Colnago has 5" of seatpost showing and he has a 34" inseam! He rides with the standard amount of knee bend.
Your #'s don't jive!
Nov 23, 2001 8:23 PM
|I have the same inseam (34"), size bike (58c-t) and post showing (ok, just a tad more--5.5" measured to the seat rails) as your brother. This guy's info is wrong or he's just messing with us.|
|wait, I know!||gtx|
Nov 23, 2001 8:30 PM
|he's using really really short cranks! Something like one piece steel cranks off a little kiddie bike! He likes to spin like mad while pedaling through the sharpest corners in crits!|

|BC - I am 5'9" with 31"inseam, but I have size 13 feet (47-Euro) I find I always go into a larger bike because at the bottom of the crank, my extended foot needs more length. Could that be your difference?|
Nov 23, 2001 11:36 PM
|Are you sure you're measuring crotch to floor, and not just using your pants inseam measurement? If so, that would explain the obvious discrepancy in numbers. FWIW, I'm 6-1, 35" inseam (measured crotch to floor) and ride a 60 cm frame.|
|any standover clearance???||C-40|
Nov 24, 2001 6:16 AM
|A 58cm Trek has an advertised standover height of 31.8 inches, which is similar to other brands 56cm c-t frames. If your inseam measurement is correct (bare foot measurement), you shouldn't even be able to stand over this frame in bare feet.
If this is the case, there's no way that you could have the seat post maxed out. I have 3.5cm of standover clearance, and my saddle is only 17cm above the top tube. I've got a couple of inches of spare length on the seatpost.
|there is no single 'right' size||DAC|

|I'm 6'2", with a 34" inseam (pant inseam measurement, that is), and have been told that a 60cm frame is right for me. I have one bike that is 63, and another that is 63.5, and both are good for me. Anything smaller, and I feel cramped.|
|Torso and Arm Length ?||Prince|

|What is your torso and arm length ?|
|I think the bike's fine, you're really 6'1"...||rib-eye|

Nov 24, 2001 5:01 PM
|OK, sorry. I remeasured without bulky bluejeans and my inseam is about 33". Standing over my bike with butt against saddle front I can lift front wheel 3" comforotably off the ground.|

Still, If you're comfy on your current ride, then it's good enuff...

|54cm frame, too small...||C-40|
Nov 25, 2001 6:17 AM
|Sounds like you have a 54cm frame. Measure from the center of the bottom bracket to the top of the seat tube for this model of trek. The standover on a 54cm is advertised as 30.3 inches.
From your dectription the frame is too small vertically, The 54.5cm top tube is certainly not too long either. You probably need a lot of steering tube spacers or a high rise stem too.
If your LBS knew that your seatpost was maxed out when they sold it to you, they didn't do you any favors. A 56cm frame would have cured this problem, only requiring a 1cm shorter stem to get the same fit.
You're very close to my size and proportions. I would certainly have chosen a 56cm.

|Ive gotten to the point that I dont even worry about the #'s. I test ride the bike and if it fits great and if not I move on. Ive found that the #'s are not equal from one make to the next.|| |
