I hate when Mom and Dad fight.

No, you are wrong. I don't need to google it. Take a basic course in strength of materials and you might learn something. Look up the term modulus of elasticity and see what it is for steel.

So a 274mm long steel wire with a diameter of 1.5mm won't stretch under 100kg of force?
How do you bring up modulus of elasticity and deny this? Steel is stretchy.

It will stretch about 0.7mm, which is not very much when you are trying to select spoke length to the nearest mm.
Thanks for doing the math and answering his question.
Exactly what I said.

Let's not forget that I told him to use 274mm to begin with.

the "ideal" spoke length was 274.8 also, which after science is only .1mm off target

I looking at two of the carbon track forks you carry and am wondering which would be the best aesthetic match for my black gazzetta. It's between the tange and columbus. The rakes are close enough to not really matter to me, especially since each one gives me more than the OE fork has anyways.

The Columbus fork will look better in my opinion.

Are these the same ones that are are now going for $250 on your site? You posted this a couple years ago that these were going for $195.
Also, how wide are the shoulders? I'm hoping that it will match the narrower tubing of the gazzetta.
Thanks for the help.

Same fork. Our price to purchase them from Columbus went up considerably in the past couple of years (as prices often do) so in turn we had to raise the retail price. We purchased their entire remaining stock and even though we currently have a lot of them on hand, it's my understanding that once they're gone there won't be any more.
I'm not at the shop right now to measure but a friend of mine just installed one of those forks on his Bare Knuckle and it looks great on a steel frame.
If price in an issue, the Tange fork will look just as good on your Gazzetta, I just happen to think the solid satin black finish and that cute lil' dove looks nicer than 3k carbon weave.

Thanks again.
Do you know of any 1" threaded ISO forks with 370-375 axle to crown distance (drilled for brakes). Probably my fault for sticking with old technology (but I love lugged frames and quill stems). Right now I have a replacement fork in the frame that's 365 mm and unless I'm absolutely perfect in putting my wheel in, the 23 mm tire rubs on the brake - even best case I'm at less than 1 mm clearance. Oh and I need a 240 mm or longer steerer. Am I looking for a unicorn/bigfoot?

howdy scrod.
I have a rounded off seat post collar bolt (the previous owner must have been a monster). Anyways, has anyone come to your shop with this issue?were you able to fix it, if so how? Both the bike shops by me just shrugged at my question and continued to proceed with their usual **** customer service. Any help would be rad.
thanks in advance

This is just a guess...but is there a slot in the back of the collar where you can get a blade on the bolt? See if you can borrow a Dremel from someone with a thin cutting disc and just cut the bolt in half. Then take the collar (if removable) and the pieces to a hardware store and have them match it up.
It might take a bit with a Dremel and the thin cutting discs wear down fast/can snap if you flex them too much...so expect to go through 2-3 discs. Also tape off below/above the section so you don't cut the frame if it slips.
It's a huge pet peeve when I hear of stuff like this...the bike shops should have at least attempted some type of fix or gave you some possible options/ideas to do on your own.
