A 32.5 inch inseam, will a 54cm bike be too small?help!Twiggy
Apr 7, 2001 3:52 PM
I'm looking at a 54cm cannondale and I don't know how to tell if it will fit or not. I measured my inseam to be 32.5'. What do you think??

And has anyone heard anything about a brand called Oshiner steel or something like that?

Thanks

a few words on measurments...Akirasho

Just be careful to take an honest inseam measurment... one that gets to the crotch of the matter so to speak.

In order to get an accurate measurment of your inseam, it generally requires at least two people (a friend or a... frrrriiiiennnnndd) and a moment's discomfort (depending on your layers of sub q fat, you may have to shove your measuring level into your nethers firmly). In fact, you might want to take the measurment a few times and use an average.

Given your measurment, and depending on what formula you use, this sounds like a good frame size to start with. The proof will be in how it feels to you.

Sorry, I don't know anything about Oshiner steel.

Be the bike.
I have about the same inseam....dave

Mine's 32-5/8", measured in bare feet. A 54cm is the closest fit that I can get in a Cannondale. Normally I would choose a 55cm, but they aren't a standard size for C'dale.

I've ridden a 56cm, but it provides only 3/4 inch of standover clearance and the top tube is longer than I prefer.

Try straddling a 56 to see how much standover clearance you have. If it's an inch or less, go with the 54.

I have a 32.25 inseam and ride a 54cm cad4. How low do you like your handle bar? I have a 90 deg. stem with 17.5 mm spacers and my bar is about three inches lower than seat. Fine for me , but if you like a one or two inch drop go up a frame size. Have you taken top tube length into consideration?
you should have a 56...dave

A 90 degree stem and 17.5mm of spacers, for a 3 inch saddle to bar distance? Seems like you should ride a 56cm. Measure the head tube length next time you get a frame. A 56cm frame would allow you to remove all of the spacers, since the head tube is 19mm longer.

I've kept my saddle-to-bar distance at 3.25" with an 80 degree stem and 5mm of spacers.

Ihad a 56cm Cannondale and my inseam is 33inches. That was as small as Icould go. Back then(80s) cannondales were measured center to top.

I'm 5' 8" with a 31.25" inseam and I VERY comfortably ride a 54cm. Unless you like very small frames (with lots of drop) I'd suggest a 56cm Cdale for you. BTW: Cdales measure CT and you should be able to get them in 1 cm increments (at least my Caad5 "team" frame is available 1 cm steps).

A 54 cm C'dale is going to have short TT.

If it helps - you appear to have about the same seam as me - I tried a 54 cdale when I got mine - way too small - in fact, I ended up on a 58, which fitted very well, though in theory it "should" have been a little too big - just goes to show, there's no substitute for a good long trial ride, if you can get one.
