| 2347.1 | With regard to smaller frame... | ODIXIE::RRODRIGUEZ | R-SQUARED | Thu Jul 09 1992 12:03 | 9 |

I don't know about Specialized, but about seven or eight years ago,
I was shopping the Columbus/Panasonics (Team America). When going
from a 57.5 cm seat tube to a 60 cm, they altered the geometry.
I imagine it was to compensate for what would be general rules of
human proportions with relation to height. It's worth looking into.

| 2347.2 | check out the fit directly | SHALOT::ELLIS | John Lee Ellis - assembly required | Thu Jul 09 1992 12:29 | 14 |

As you can imagine, bike sizes (being measured in linear units)
can't "run big" like say shoes or shirts (with American size-numbers,
as opposed to other countries' which use linear measurements).
58cm can only mean a few things, e.g., center-to-center from
crank spindle to top-tube, or center-to-top. That's a variance
of maybe 1cm. Anyway, the simple thing is just to go down when
the bike comes in and see if it fits. (A facile answer, I know.)
Bearing your inseam and other bodily proportions in mind, a good
shop should be able to check the fit pretty simply.

| Just an FYI, Jim, but 60cm does not equate to 24'' or 25''.
60.0 cm = 23.6 inches
61.0 cm = 24.0 inches
62.0 cm = 24.4 inches
63.0 cm = 24.8 inches
63.5 cm = 25.0 inches
You need to find out what size you need and go from there.

If it's 60cm center to center, then it's going to be
really close to 24" center to top.
I think that some manufacturers measure center to top of lug.
On a Cannondale this is significant.
The sizes are rarely spot-on anyways.

| 2347.5 | More confusion | DNEAST::APPANEAL_JIM | | Thu Jul 09 1992 16:52 | 18 |

This gets more confusing on the size all the time! this would tell me
that 58cm= 22.8" which really sounds small?? can you actually convert
a cm to inches and expect it to be the same??
Also at noon I took arun to another bike shop here in Nashua.
They had the exact same bike, a 91 selling it for a sale price of $499.
and The bike salesman in this store also indicated that in this brand
he would expect I would take a 58 cm where he said a 60 in another
brand??
I guess the only real way to know is wait for it to come in and see how
it fits!!
Can anyone give me some pointers on what to look for for the correct
fit??

I did a DIR/TITLE=FIT since the first of the year, but only found
the following. There must be older notes.

There are multiple dimensions of bike fit, and many rules-of-thumb for
fitting you to the bike.
Important measurements include inseam (or its equivalent), tibia
length, torso length, and elbow-to-hand length. It's important to get
the correct frame size (and geometry), but presumably you should be
able to get the brand you want in the size that's right for you.
(An obvious statement, but what I'm saying is, if you prefer the
Trek's (or Fuji's or DiamondBack's, or whatever's) geometry, components,
ride, etc., but the frame they have in the shop doesn't fit you, you can
order one in that brand that does.

| General Rule is that you have about 1" of clearance between you and the top
tube when you are standing flat footed over the top tube. If you are planning
to race, you might even consider 1.25". From there, the salesman should know
how long of a stem you need, saddle adjustment etc.. You might even consider
spending some money to get fitted. Some shops do it for free if you are
purchasing a bike that is about $600 and up. The problem is that since you are
looking to spending $350.00 for a $550 bike, the shop employee might not give
you that extra service because he is not making any money on that bike.
Good Luck,
Dave

| 2347.8 | I bought it! | DNEAST::APPANEAL_JIM | | Mon Jul 13 1992 14:54 | 7 |
| Well I bought a road bike on my way back to Augusta on friday! I
stopped at a bike shop in Freeport and they had a 60 cm "91 Trek 1000.
The price was the same as the Specilized and it has an alunimum frame.
The compoents are not as good the other bike had Suntour edge, and this
has Suntour Blaze, but it fits!!!
Thanks for the help, Jim
