What size frame are you riding?

[William]

So I was curious as to whether the size of bikes that the Forum membership rides will follow the standard Bell curve....and I had a few minutes spare time on my hands between activities. I thought I would create a poll tat would cover the majority of the size range that folks ride. I realize a few people will fall out side either end of the poll but I only had ten spots to use.

I know many folks have more then one ride, so lets make the you main ride - the one you ride the most. So, please mark the range your main ride falls into. If you feel so inclined, please post your TT length and stem length you are using as well. For the sake of uniformity, all measurements should be center to center.

I'll go first:

ST: 64.5
TT: 62.5
Stem length: 130



Thanks,
William

Not sure what you'll get out of this. C-C sizing is all over the place due to tube diameter differences. And without seat height or body height, the numbers aren't going to tell you much about fit or why that stem for that frame. So, what's it for?

ST 50cm
TT 52.5cm
Stem 110mm

Just curious where it leads. And, I 'm not a cat so I should be ok. ;)

[Ken Robb]

frames from 59-62CM c-c. Top tubes 58-60cm. A bit taller than most guys my size (6'1) would choose but I like my bars even with or a bit higher than my 79cm saddle height.

seems us midgets skew the distribution :D

drop varies across bikes from 5-8cm
saddle at 75cm

Fun stuff. I'm also curious about saddle/bar drop.

i feel this would be a function of flexibility/age... so depending on how you built your scale, there'd be a fair bit of skew towards smaller drop.

Two 24in and a 59cm and a 60cm.
stems vary, drop about 4cm.

Stem length: 130
Drop: 9cm (13cm on my SS).

PS: I didn't consider sloping TT's when I posted this. Just not on my radar. I guess virtual ST's would be appropriate then.

Jeez, couldn't you find a bike in your size? :)

[dana_e]

is that center to center

or center to top

sloping, -6, -8 degrees

or virtual ?

Gets the job done for me ;)

Give or take (some bikes have sloping TT's)

yes, agreed there is prolly a high correlation with age. not trying to make anyone feel good or feel bad. it is what it is. people need to be set up to be comfy, that's it.

[TimmyB]

Well,
my carbon race bike is 55x56 w/ -10° 100mm stem w/ no spacers, setback post. about 8.5-9cm drop
my (comfort) steel race bike is 57x57 with -8° 100mm stem w/ a 1cm spacer, no setback post. about 7-7.5cm drop
my beater/school bike is 56cm square with riserbars. like 10cm RISE :)

I'd say for going fast my frame size is 55x56cm. I've got longer legs and a shorter reach. I'm 6ft. 19yo

[roguedog]

46-49cm st
50-52cm tt

yes i'm short

[rice rocket]

Yes, we need more midgets to skew the results! :)

[AndrewS]

seems us midgets skew the distribution :D
Actually, it's probably the compacts.

Take that into account and what do we get: A distribution in a bell-like curve! Amazing.

[alexstar]

55 square with a 115 quill stem.

Hmmm, do I detect a note of sarcasm? :fight:




William ;)

[RADaines]

ST = 53 cm
TT = 54.7 cm, 5 degress of slope
stem = 100 mm


This is a custom frame so how it compares with standard frame sizing is a question.

[jblande]

st: 59
tt: 58.5
stem: 120

I believe 9 cm of drop, but I am not sure.

[snah]

Not PC, think we're supposed to say short people. :)

57 square myself, 120 stem.

[207 cm]

61x68 w/140mm stem.

[Jack Brunk]

55-56cm TT
Doesn't matter on the ST(relative to either straight or sloping)
120-130mm stem minus 10-12 degrees
7cm drop

[Lifelover]

I can make do on anything between a 56 square and a 60 square.

I only want 1" or less of drop so the smaller frames tend to have VERY ugly spacer stacks.

[weiwentg]

Compact frame.
56cm TT.
46cm ST, center to top.
76 degree STA.

I'm 5'5" with a very long torso. I need custom to really fit right. I wanted lugs but we couldn't get a level TT design that looked right - it would have to have a riser stem (as in stem above horizontal, would look funky).

Cool to see so many on the shorter stature chime in on this thread.

Custom Dean Ti: 44 ST, 53 TT (11cm 84* stem) - "Race Bike"
IF Planet X: 48 ST, 53 TT (11cm 84* stem) - "uh, Cross bike"
Custom IF SSR: 48 ST, 52.5 TT (12cm 73* stem) - "All around"

I'm 5'5". Saddle at 65.3 cm, Saddle drop is about 4 cm on the Dean, less on the other two.

Just for kicks and grins, I'm 6, 3.5" and 90 cm PBH.

I'd love to know the height and PBH of some of the riders of some of the bigger bikes. William, 207cm, Jeff N???

Jack's got this nailed. Seat tube length means little these days, it's the (effective) top tube length that helps most to dial in your fit, reach, KOPS etc. (if you use or believe in KOPS)

[learlove]

-ST 52cm ctc (53.5cm ctt)
-TT 54cm ctc
-Stem 120mm
-Seat height 70cm from center bb to top of seat (along the seattube/seatpost line)
-172.5 crank length
-Level top tube, standover 30.5in or 77.5cm (700X23 tires)
-I'm just shy of 5'9" (5'8and 3/4" to be exact) with a 31.5 inseam
-with todays limited size production (51 to 53cm or 52 to 54cm or Sm to Md) i almost find myself falling right between the sizes for a "perfect fit". For example, Cannondale, A 52cm is slightly small and the 54cm is slightly big, both can be fit fine but not a perfect as if they made a 53. Same for most other brands.

[victoryfactory]

Looks like a pretty normal bell curve to me, with a
fairly standard distribution if you adjust for error
(and weird fittings)
