I just got back from the bike shop and had some simple sizing measurements. This was because I was thinking of purchasing
a Surly Long Haul Trucker.
He used a slide type calculator with the feet and inseam to derive:52/84-86 >69.0
Added the Torso with the Arm Length to get 116.6 close to 61cm minus 11 (stem length?)=50.
I told him to focus on the top tube length for me, and he felt that best frame combo was the 46cm frame rather than the 50cm. That the 50cm would have too long a top tube.
I was kind of shocked. He pointed out the TT(Effec.) on the LHT chart on the 46cm frame was 515.0 and the 52cm frame was 530.0, which he felt was too drawn out for me
to have a comfortable upright riding position.
But I was surprised in pointing out that the Head Tube length with the 46cm frame was 116.7 mm and the 50 jumped to a 144.0mm length (HT) What's up with that?
Wouldn't I then need more spacers to get the handlebars up to the saddle height?
And what is the deal of not offering a 48cm frame? Why the jump from 46 to 50????
Thanks for any advice and help.
Here is the frame geometry page from Surly
It kills me that they cut the steerer tube. If you order the complete bike, which is the way to go, they cut it. Only if you order the frame and fork, does it come uncut. I stand corrected.
Must have been bad information. Thanks, guys.
