Bottom bracket height Big Dummy?
I am thinking about buying a Big Dummy frameset in the next month or so and am having a hard time finding out the bottom bracket height for a 18" frame (with 26x2.35 tires if possible). I have an xtracycle conversion currently and would like something a little less flexy and with a lower bottom bracket. I am sure the Big Dummy would flex less, but have no idea how high the bb is and can't seem to find that measurement anywhere.
Thanks in advance,
Bruce

Just an idea in case you don't get a response here...you might try posting in the Surly specific brand thread (surly manufacturer forum) over at mtbr forums. I bet one of those guys has a BD sitting around they could measure for you right quick.
Another idea would be to post a message/question over at the Official Intergalactic Surly Regional HQ page on Facebook.

Surly lists a BB drop of 40mm. Subtract that from the radius of your tire/wheel combo.

So, from my measurements, it looks like the Big Dummy would have a BB height of approx 11.7" with the 26x2.35 cst metropolitan palm bay tires I am currently using. This is a full inch lower than my current xtracycle conversion. I will add this to the "pros" list of buying a Big Dummy frameset!
Thank you everyone,
Bruce

Well, that just makes too much sense
