6' 2.5", cycling inseam of 78 cm. 57 cm Mitis, with a 130 stem and 175 cranks. I sometimes wish the bike had a longer TT, but I wouldn't move all the way up to a 60.

Great thread but only a couple of 5'8' ers and one of them undecided. Me too.
I'm 5'8 with 31.5 inseam wanting a red/black Orca so bad!!!
Would you recomend a 51 or 54 cm???
Thanks!

5'7" here and a 30.5 inseam and I'm thinking about having my LBS order me a 51 with a 100mm stem (535mm tt + 100mm stem). It's a toss up for you but I'd be inclined to think you would be fine on a 51 with a 110mm stem and maybe run a post with a slight offset. Unless you're very comfortable on the 54, I'd go for a 51.

I'm 5-10 with a 32 inch inseam. I've been riding for 30 years and usually a perfect fit for me would be a 56-57 but I bought my Orbea Opal in a size 54 and it fits me perfectly. My Orbea dealer explained to me that the Opal geometry was designed to be used with a longer stem (I have a 120) than you'd typically use to get more weight out front aiding an aggressive riding position.

5'-10.5" 32" inseam, 54 2008 Orca that I just ordered today at my LBS. Can't wait to get her built and on the road.

You'll be glad you got a 54. It seems that riders 5-10 to 5-11 are split 50/50 on 54 or 57 frame sizes. But Orbea (at least the Opal) fit totally different than anything I'm used to. My Opal is my 9th road frame in my nearly 30 years of cycling all my previous frames were either 56,57 or 58. I would have bought a 57 myself if my LBS hadn't talked me out of it. With a 57 I would have been forced to use a 80-90 mm stem which would have thrown the balance of the bike off. Weird though because even measuring it with a tape you'd swear it was going to be too small until you actually ride it.

my adventure

I thought I would share my sizing experience with a 2009 Orbea Orca. I am what you call, the inbetween size. I am 5'11" with a 32.5 inch inseam. after getting sized, and sized again, the 54cm was just too small. I would have been sitting sky high, and the bar drop would have been huge.

What I found. 1, at my size, a Felt 56cm is the perfect fit. But I love my Orca, and the 57 was going to work. So, I have a 100mm stem, with almost no spacer. I just switched from an offset post to a thomson with 0 offset. Bottom line, the bike is near perfect now. No, I don't have a euro-pro 120mm+ stem, I guess I had to give up that uber cool look.

Bottom line. If you're 5'11'' like me, you're not going to get the "perfect" fit. But based on my experience and my measurements, the 57cm is in fact the correct bike, and is near perfect. I would advise anyone spending this kind of money to get sized before buying, and if you still have doubts, do the sizing again. If you're in between, don't guess, or estimate, just do it again until you're sure.

oh, and the blue orca, gorgeous i'll update my picture in the thread soon once i get my final upgrades for the year...

About to buy the gold Orca 5"10 30 inseam and they reccomend the 54. I am skeptical of the size does that sound right?

I'm 5'11" with a 30 inseam and ride a 54 Opal. But, I'd echo the frequent posts in these forums of ride it first if you can.

check out the chart here: http://bicycling.about.com/od/howtoride/a/bike_sizing.htm

From the chart I'd say your at the high end of 54cm riders. The chart fits you somewhere between 54-58. I'm 6'0 with a 31" inseam and fit nicely on a 57cm Onix. I'd definitely give both the 54 & 57 a ride ... top tube length will make a difference in proper fit.

I'm 5-10 with a 32 inch inseam. I ride a 54cm Opal. Been riding for 30 years and all my road frames have been 56-57 cm. The Orbea Opal is the exeception. Trust your LBS the 54cm WILL fit you.

 

[WhyRun]

top tube length will be the determining factor, if they say 54, do it. (5'11" - 32.5 = 57 orca for me)

 

[FlynG]

Sounds right, I'm 5'9" 31" inseam and I'm on a 51 Opal which has a TT of 53 or 53.5 if memory is correct.

The top tube length, while important, can be misleading when selecting an Orbea (an Opal at least) my LBS explained that the Opal was designed to be run with a long stem to get more weight over the front wheel. If you're currently riding a 57 and running a 100-110 stem you would have been better off with a 54 and a 130 stem.

Hi guys, I'm currently looking at a secondhand '08 Orbea Orca in size 54cm. I can't go and ride it, as it's not located in my city, and I don't have an Orbea dealer in my town either.

My 'specs':
Height: 167.40cm/ 5' 5.9"
Inseam Length: 79.40 cm/ 31.25"
Arm Length: 57.70cm/ 22.71"
Shoulder Width: 37.50cm/ 14.76"
Weight: 56.00kg/ 123lbs

Bike 'specs':
Frame: 54cm
Cranks: 175mm
Seatpost: 300mm (Ritchey Full Carbon WCS 1 bolt)
Stem: 80mm (the guy reckons he can swap it out for any length though)

If the stem and cranks are to long/short for me, then I can easily swap them out, the frame is what really matters, do you think it would be OK? I see a couple of people in this thread are around 5'7/5'8 and are riding 51cm and even 48cm frames, so it's a bit confusing. Cheers.

I've been riding, racing for 30 years all my bikes have been 56-57cm and I'm 5-10. However I have a 2006 Orbea Opal and it's a 54cm. The Opal frameset (according to my LBS) was designed to be run with a longer stem to get more weight out over the front wheel. All my other bikes I ran a 100-105mm stem. I run a 120mm with my Opal. My best guess is yes the 54 you're looking at will fit you.

tcurtbike I just re-read your post. I thought you were 5-9 but upon looking again I see you're 5-6? In that case a 51 would be your best bet. The 54 will fit but you'd be looking to run a shorter stem. Probably why the seller only has an 80mm stem on it now.

6' with a 34 3/4" inseam. Does a 57 cm Mitis sound right?

 

[Timbuctoo]

193 cm/s or 6"3. My bike is a 60cm Orbea Onix and it fits perfectly with a shortened stem. Just a bit to much reach with the standard longer stem.

6'4" 35-36" inseam and ride a 60cm 2009 Onix

My onix is a 54 cm and i am 5'10" . I was shocked, a 54? The specialized and cannondale 56cm's fit me best, and they told me that I would need a 58 on a trek. I hope the 54cm was right for me. Not too much seat post showing although they did move the seat a little back.

That happens,,, it's why you test ride.

You can swap out the stem for longer/shorter
for other bikes I looked at...
Specialized I fit a 61 cm
Trek Madone 4.7 62 cm
