HELP!!! WITH FRAME SIZING FOR BIG GUY(14 posts)

HELP!!! WITH FRAME SIZING FOR BIG GUYstillridn
Sep 2, 2003 7:52 PM
I need the forums help again. I am 6'3 with a 35 inseam ,I also have a fairly long torso. I have my heart set on the 04 Specialized Allez Comp. I am glad I waited for the 04 but I am bummed about the size changes. I wanted a 03 61cm numbers as follows s.t=570 , t.t=594, h.t.=210. For 04 they go from a 60cm to a 62cm. The 60 has a s.t. of 560, t.t.=591 ,h.t.=205, OR the 62 has a s.t.=580 , t.t.=60.5 and a whopping 220mm head tube. I like the long t.t. but that head tube is huge. I like a agressive riding position. Is there a noticable difference between a 594 and 591 top tube and 205 head tube vs a 210? I am leaning towards the 60 cm bike and would like some feedback. I realy would appreciate any help I could get. My local dealer is great ,but not real helpful when it comes to sizing issues. I have no options as it relates to Specialized dealers in my area.Thank You very much for any help

I am nearly the same dimensions as you (6'3'' and i have 36'' cycling inseam). I consider myslef to have a long torso but i suppose yours is a bit longer. I also am searching for a bike with a long TT. I personally would have the dealer look for a '03 61cm. The '03 61 would be a perfect fit for me. As for the '04 60 and 62 sizes, you and I are exactly in between those sizes. If you like a bit of a drop to the bars then you should probably choose the 60 because with the 62 (and the compact frame geometry) your seat will nearly be even with the bars I would think.

I am also in search of a new bike and I'm looking at the Bianchi SL3 aluminum/centaur bike. Bianchi's 63cm frame should fit me well- st=60cm (c-t), tt=595 (horizontal). Bianchi has a slightly sloping TT but not nearly as much as the allez. I like the sloping TT b/c it gives me enough standover clearance yet still has a long enough TT.

I hope this helps, good luck with the decision
just ride them both and go by feelDrone 5200

you are in the right ballpark with either size. Go ride them. You will know which one is right.

For what it's worth, I am 6'3.25" with a 35.5 inseam and what I would describe as a long torso. I am very confortable on a 62cm trek OCLV with 130 mm stem.

Go ride the bikes! That's the only way you will know.

get your adjustment from the stem. Just make sure that your bike shop agrees to swap out the stem at no charge until you perfect the fit since he isn't doing anything else for you that is value added and trying to sell you a bike unridden.

With the sloping top tube you won't have a standover problem. You can always shorten the stem and use a -10 degree and no washers to get an aggressive position.

If you went with the smaller size you might have a 130mm stem on it and still need another cm and not be able to get it.
the 60 should be OK....C-40

The 3mm shorter TT is insignificant and the 5mm shorter head tube should not be a problem, UNLESS you are one of those guys who can't ride a NORMAL 8-10cm drop from the saddle to the handlebars.

My inseam is 6cm less than yours. I ride a sloping TT frame that has a 6.5cm shorter seat tube and 6.5cm shorter head tube. I only need 5mm of steering tube spacer with an 84 degree stem to maintain a 9cm drop from the saddle to the bars. A 90 degree stem will eliminate all steering tube spacers.

I do use Speedplay pedals with Sidi shoes, that reduces my saddle height by as much as 1cm over other pedal/shoe combinations.
I'm only an inch taller, and I wouldn't even GLANCE at a 60cory

I'm 6'4", and while we may have different proportions, I wouldn't even consider a 60cm. I rode 62s for years because that's the biggest off-the-rack frame you can find in most shops, and I was never really comfortable. Rivendell's sizing guide recommended a 65cm Atlantis, and I bought a 64 because that's what they had. It's a huge improvement over the 62s. Many people, probably most, ride frames that are too small by classic sizing methods. We all talk about how fit is the most important factor, but then we buy small frames on the theory that they're lighter and stiffer.
Before you buy, why not at least take a look at Riv's guide at www.rivbike.com? See what they recommend, then decide if you believe it. It worked for me.
inch taller, but what's your inseam???C-40

It's saddle height that is important. The poster has a fairly short inseam of only 35 inches or 89cm.

IMO, the rivbike.com guidelines are for old men with bad backs. If you follow those guidelines, then the larger frame would be the obvious choice.
you can't compare head tube lengths...gtx
Sep 3, 2003 8:09 AM
you can't compare head tube lengths between two frames without taking seat tube angle and bb drop into consideration. For example, my Merckx has a shorter head tube than my custom frame, even though it is a slighly bigger frame--this is because it has a lower bb and a more relaxed STA (and these are old school frames before threadless setups came along). Anyway, the head tube length thing is mostly an aesthetric issue because assuming you're not Grant Peterson or an old man with a bad back most people are gonna be able to get the bars where they want with a fairly normal stem/spacer setup.

If all else fails, try riding other bikes that are a little too big or small...personally I've found I'm much more comfortable on a bike that is slightly on the big side rather than one that is too small, though no doubt the opposite is true for some people...am currently riding a 61cm that feels great, had a 59cm before that that never felt right, have a 34" inseam FWIW.

How about this!Zman

Big Man,

I would say that you have long legs and a "shorter" torso. I am 6'3" tall and have 33 inch legs and a long torso.

Have you ever tried Lemond Bikes? They seem to work best for long legged and shorter torso persons, they have shorter top tubes.

If I had your specs I would still ride a 60 (both C'dale and Trek) but my seat would be higher and my stem shorter.

If I had to decide between larger or smaller I would go smaller, you can always stretch the bike out but making it smaller can be a issue.

A sweet deal on a nice bike, my first road bike, fell into my lap at the end of May. I really liked the bike, but it was smaller than what I thought I should ride.

I got a fit session and low and behold... at roughly 6'3 w/ almost a 36 inseem, I was still able to fit a 59cm bike with a 57.5 tt.

I have a 130 stem on it with a 6 degree neg rise, about 14cm of seatpost showing, and (I think) a fairly aggressive drop from saddle to bars... I don't know how much exactly.

Here is a pic of my setup, sorry I don't have a pic of me on it so you can see how I fit. But I really am quite comfy on it... my riding style is "in the drops" doing my commute like it's a 23 mi TT (I'll break an hour some day :) I've only done one long ride @ 5.5 hours (55 miles w/ 3k+ elevation gain), I had no fit issues whatsoever, the bike feels great.

As others have suggested, ride similar bikes, check out "bike fit" sites, and if you can get a fit session. Find out what different size bikes you can ride with what adjustments... we're not bound to just one size bike, with fit modifications we actually fit a couple sizes. You could prolly get either bike to fit... but the smaller would be my choice.

Also FWIW, I test rode an 02 61cm Allez Elite and it felt good to me. I would not have wanted it any bigger.

Good luck!

p.s. My steerer has been cut since the picture :)
Went with the 60cm.Thanks for the inputstillridn

Nice Pinarello. I think with the 72.5 s.t.a. and the 591 t.t. with the 130 stem I will be perfect. I have my stem slammed in my 62 C-dale and I woul like it a little lower. My never built Eddy Merckx MX Leader is a 60cm with an even shorter t.t. and a 72 degree s.t.. I was fitted for this bike 9 years ago and have not grown since. Thanks for all your input. Now I have to wait until October to get it
