Mtb Chick needs help......(9 posts)

Mtb Chick needs help......mtbchick

hi! i am new to the roadie world and am about to buy my first road bike. a friend offered me a klein quantum for real cheap, but it is a 55 cm frame. i am only 5'4'' and have an inseam of 32 inches (really long legs). we adjusted the seat and seatpost, etc., and the bike rides back or knee pain. i was wondering what are the disadvantages of riding a bigger frame like this one. i won't look like a fool, will i? thanks for the help in advance. -mtbchick

Looking like a fool would be the least of my concerns...maybe it should be higher on my personal priority list...but I digress...
I would be surprised if a 55cm Klein would be a viable long term fit. It is not the seat height in relation to the cranks, but the length of the top tube. Even with a very short stem, I'm going to bet the reach is going to cause big time discomfort on longer rides.
I just checked out a Klein Quantum Race, 57cm, and found the top tube dimension was about 3cm greater than my Cannondale, which is a 56cm. I took a pass on the bike, even though it was a great deal. When I mentioned this discrepancy to a buddy he told me "Trek runs small (a 58 is like a 55-56 with a lot of other manufacturers) and Kleins run big". I don't know if that is accurate, but I would definitely go to a knowledgeable shop, if possible, for a looksee and, potentially (if everything checks out), fitting before plunking down coin. In the long run, it makes more sense to spend a little more (or find another deal) than to save a little and end up paying for it everytime you ride.
Kleins must be for people w/ really short legs then :-)kenyee

I'm long legged and short torsoed and Treks don't fit (they're for short legged long torsoed people)...

Your troubles wont start with the inseam.. It will be in top tube length. You may not notice it so much on shorter rides, but on longer rides, you'll wear yourself out supporting your weight over the longer tube. Welcome to the "other side" !

I bought 54cm Cannondale 'cause I got a great deal & didn't know much about sizing. I don't have alot of clearence on my bike & I'd image that Kein is cutting it a little too close. On my bike I ended up replacing the stem with a 9cm, which is probably as short as you'd want to go. On my next bike, I figure a 52cm would be more like it. Also FWIW, I got my C'dale used on this site. Everyone will tell you to get one that fits & if you look around, you can get a good deal too.

You're going to need a frame with a short TT.

Check out the Giant small frame. It's got a 53cm tt which would probably fit you as good as you're going to get.

32" inseam and 5' 4" .... wow!
55 is fine!!!PODIUMBOUNDdotCA

You'll have no problems with a 55... I'm 5'9 and have a 32 inseam and ride a 55 ideally but most frames only come in 56 so I just move up a size. With a 56 I just need to use a slightly shorter stem but not much shorter. Since your 5'4 you may need to get a shorter stem but if your not experiencing any back pains then leave it for now and maybe invest your money later. I remember my first bike had me stretched out since the stem was a tiny bit to long but I've always been flexible so it never bothered me... but people would wonder how I was comfortable.

Anyway most big bike shops have a fit kit where they can help you figure out what stem you need... and your a chick so you might be able to get it for free if you whine a little then pout!

For a 32" inseam a 55 cm is probably pretty good. I suppose the t/t may be a little long.
