Well, we got our Disc Truckers. I had them give them to us with the steering tube uncut since they insisted on cutting it to the length they thought it should be with no extra. This is from them taking a measurement from a different bike we were measured on to determine frame size. The steering tubes were going to be cut before we had seen them or sat on them for the first time. So I said no.
Of course this is going to take a lot more time on my end to get the bikes in riding condition. I've got a star nut installer and cutting guide ordered. Then there is the matter of spacers.
Surly Truckers come with four 10mm spacers. On my bike this leaves the bars a little over an inch lower than the top of the seat. My bb to seat distance is pretty well dialed in, but I will have to do some careful fitting on my wife (who is very new to riding) before I determine hers.
So I have two questions.
1. As a starting point, where would you position the handlebars in relation to the seat?
2. After that has been determined, how much steering tube would you leave above the stem for the initial cut?
Right now with the tube uncut, there is about 70mm of tube left above the stem with the 40mm of spacers underneath. I don't have any other spacers and the star nut is not installed, so as long as I have to wait for everything I might as well make a cut as soon as everything arrives to make the steering tube a reasonable length.
I would like to have plenty of room for adjustment for our first riding season while not having an unreasonable amount of steering tube above the stem. Stems might also get changed in the near future. The stems that come stock have 40mm of space on the tube. I don't know if this changes with different stems or if this is a standard size. I haven't touched a bike since quill stems.
Thanks for any info and advice.
