Can I make a 62cm LHT work for me?

I know I have posted way too many threads about frame sizing, so please forgive me in advance. If I had the money, believe me I would just have a custom frame made to fit me perfectly and never look back, but I am in my mid 20s, and money isn't exactly falling from the skies right now. Ok, now that I have that out of the way, here goes my question.

I have been eyeballing either a Gunnar Grand Tour, or a Rivendell Sam Hillborne, but both of these bikes cost more than I would like to spend right now. I just flipped through the newest issue of Adventure Cyclist(April 2011), and in the gallery picture that is always on the last page, I noticed that on of the cyclists is 6'6" and rode a 62cm Surly Long Haul Trucker! I had already decided that this bike was too small for me being 6'3.5" with a 93" pubic bone height and a 83" saddle height. Anyway, this leads me to believe that maybe I can get a 62cm Long Haul Trucker to work for me if I don't cut the steerer tube.

I checked out the geometry very closely on the 62cm frame with 700c wheels, and I just don't see how I can get the handlebars even, or higher than the saddle. With a 62 cm frame, my saddle will have to be approximately 20 cm above the top of the seat tube to achieve my desired saddle height. I checked the head tube length and then looked at the fork steer tube length, and if I leave it un-cut, it will extend 11 cm beyond the head tube. I know the head tube extends above the top tube quite a bit so maybe that adds another few centimeters. Lets say that gives me 13 centimeters of height above the top tube to the top of the steerer. Somehow, the get my bars even with the saddle, I would need to get another 7cm higher!!! Can this be true? If it is, that means a stem with no rise would leave the bars almost 7cm or 3 inches below the saddle. That is WAY to far below the saddle for a touring bike for me. I want my bars to be at least level, or above, and I don't think there is a stem out there that will even get me 3 inches of rise.

Sorry for the ridiculously long post, but I have had a terrible time getting bikes to fit me. Am I figuring out all of these measurements correctly, or am I missing something. If I can fit on an LHT, that would be terrific, as it is a great frame and would save me a heap of money. Please let me know if I am figuring this out correctly, or if I am missing something important.

Thanks

If you just need the steerer tube to be longer then you could add an extension. I've never used one or know much about them, other than the fact that they do exist.

I'm pretty sure your pubic bone height is not 93", unless it is above your head. And if your saddle height is 83" inches you must be riding one of these:

You need the LHT sizing spreadsheet. Look here.http://spreadsheets.google.com/ccc?k...31WpvkCw#gid=0

BR, I wasn't able to follow your frame analysis, probably because I just returned from a ride and too tired to think. When you say saddle height are you talking from the center of the bb to top of saddle? FWIW, I am 6'05 with a 93.7cm pubic bone height and my saddle height, from bb to top of saddle, is 83cm. I like my bars about an inch lower than the saddle. I used to own a 62cm LHT and that's how I had mine set up. I was hoping to find a photo but I could not which is sad because I thought I had photos of all my bikes past and present. Sounds like we are pretty close so I would think it would work for you. If you buy a frame the steerer is uncut. However, that's not the case if you buy the complete bike unfortunately.

I mentioned it once but I really suggest you check with SJS Cycles to see if the Club Tour would fit you (which I know it will). You have nothing to lose by completing their fitting form and sending it to them. Here is a picture of my Sherpa with an uncut steerer and ridiculous amount of spacers but it works and I am comfy on it. Disregard the front rack which is leaning forward. I was trying to see if a Blackburn front rack would work. They are very good at fitting people thousands of miles away and won't sell you something that won't work for you. The Club Tour would get the bars even higher than a LHT. It will cost you about $300 more but it has better tubing than the LHT.

You got me there! I was typing pretty hastily as it was a long post already, and I accidentally wrote inches instead of centimeters, so it should say 93cm PBH and 83cm seat height.

I don't see why it wouldn't fit, have you tried it at a shop?

I'm a shade under 6'4 and ride the 62 LHT. Got it as a frame set and put on the stuff from my old bike on it. I've got a 17 deg x 130 bontrager stem and butterfly bars. The stem is about even with my seat. I love it, but could stand to raise the stem up another half inch. I could still probaly get close to that with more risers and just hanging some of the stem up over the top of the steerer tube. The clamp on Bontrager stem is really long.

Seriously, look at the spreadsheet. There are a number of riders your size or bigger who have contributed data and comments. For what it's worth I ride a 60cm LHT, and am 6'2", with a 33" inseam.

I always found that the Rivendell chart selects frames way bigger than I would want to ride. Looking at your PBH on their sizing chart I would think that the biggest frame I'd even consider if I had a PBH of 93cm would be a 62cm. I'd probably go with a 60 myself, but I like my bars well below the saddle.

Only you can say what will work for you, but I am sure that a 62cm is plenty big enough for at least some riders with the same PBH you have.

Old school .. stand over the frame , lift the front wheel off the ground a few inches ,
and it's adequate for road riding..

Try to find a last gen Salsa Fargo in the XXL or XL size. It comes with a 350mm steerer tube, and the fork is longer to start with (IIRC, 465 vs. 400mm). You can get your bars way up with this setup. They were being blown out for about $350 a few months back, but I'm not sure if any are left.

After reading your post more carefully, I'm only a bit smaller than you. I'm 6'3", 81cm (32") saddle height, with a 91cm (36") pubic bone height ("cycling inseam")

Here's a picture of my 62cm Crosscheck:


Uncut 300mm steerer tube, riser stem (17* x 100mm, I think), and the bars are just a bit above the saddle. The LHT has a longer steerer, I think, so you should be able to get your bars higher.

By contrast, here's my XL Fargo:


Uncut 350mm steerer, bars maybe 2" above my saddle, and I still have probably 40mm of spacers above the stem!

(Wow, that's a crazy mix of metric and English units.
)

I think an LHT would probably work fine for you. The Fargo might work even better, since the top tube is a touch shorter, but the head tube and fork are considerably longer. You seem to be pretty leggy for your height, at least, relative to me.

Thank you for the help everybody. I looked for one of the older XX large Salsa Fargo frames, but have not been able to come across one. I decided I have enough info now to determine that there is at least a decent chance that a 62 LHT will fit me. So, I ordered one up, and I will build it up with some parts I have laying around and see if it works. I figured for the price of one of these frames, it is worth giving it a shot. If it ends up not working out, I will just sell off the frame and move on.

I am about the same size you are. Last year I was looking for a new frame and it was between the Salsa Vaya and Surly LHT. I finally decided on the Vaya. I thought it might be fun to try disk brakes. I was actually basing my decision on frame size on top tube length. The Vaya has a 600mm TT and the LHT has a 610, either of which would work fine. With the long seat posts available now (I got a 350mm Easton) fitting a smaller seat tube/long top tube bike is much easier. Greater clearance on the top tube during dismounting is always nice.

I would suggest you find a good LBS and get them to help you. Seeing a person on a bike in person is 10000 times better than trying to understand a slew of sizing numbers and what it all means.

So do I and so am I.

OP: I think a 62cm will work for you. My bars are a tad lower than my saddle and I still had about 1" of steering tube left that I just had cut today.
