2013-02-21 Thread Scott Henry
Jim might be able to more acurately chime in on this, but after about a
dozen years in the shops, I think its the other way around.  Shops make
money on partsand labor.   At least for me, standard markup on a complete
bike was in the 30-35% range.   The markup on parts was 100% and labor was
just pure gold.  Thats was years ago, but even then the labor rate was
based off of something like $75 hourly.  Your shop may vary, but thats how
it worked in my area (Cincinnati).

We liked to sell hot bikes for one reason only, because we got to build
them.  There was a special enjoyment from wrenching on top-o-the-line
stuff.  The boss wanted us changing front tubes all day, they were the
fastest easy money that you could make on a two minute repair.

More or less, a shop saying you can't run a 130 wheel in a 126 frame is
just lazy.  It probably tells me that the employee was also the mechanic
and just didnt want to do the work.  He'll get paid minimum wage either way.

I can certainly envision several reasons why your LBS told you that.

It could be that the shop employee was inexperienced and doesn't know much 
about older bikes. 

Or it could be that the shop doesn't want the liability associated with 
installing parts that are, technically speaking, incompatible with the frame. 

Or maybe, they've gone down the rabbit hole of modernizing old bikes in the 
past, and feel that it isn't worth the trouble. I know that I've had experience 
with that kind of thing, where some unforeseen and seemingly trivial 
incompatibility issue causes the project to take 5x longer than quoted and in 
the end, the solution was a kludge that isn't 100% satisfactory.

Or maybe you're the fifth guy this week who wanted to put a modern parts group 
on an old bike, and they figured that, like the previous four, you'd balk at 
the high price, and it would be just easier for everybody if they cut to the 
chase and say no. After all, buying a parts group and wheelset and the labor 
to install it all can often cost as much as or more than a new bike that has 
the same parts and wheelset.

Jim, based on my experience, you are right on the money.  When I got out to 
Colorado and wanted someone to just look over my 1971 Schwinn SS, no one in 
boulder would even touch it, and only one shop in Denver would.  That 
particular shop (CycleAnalyst) had an experienced mechanic that did a nice 
job of getting the bike safe again.  But it wasn't easy.  And I wasn't 
trying to update it.

2013-02-21 Thread Ryan Ray
I had some shops tell me I had to do it and some tell me I didn't. Then I 
just tried it after all the hubub and my frame was slightly wider than 126. 
I didn't really have to pull it apart much at all so I just went with it.

The must-cold-set folks lose a little credibility with all the steel frames 
that measure 132.5 or whatever and let you use both MTB and road hubs.

Still, if it was a super nice frame and was a tight 126 I'd pay to get it 
done right.

2013-02-21 Thread William
Remember RB1s were spaced 128mm when they came with a 126mm 7 speed rear 
end or a 130mm 8 speed rear end.  

Remember also that the first Shimano 130mm rear hubs had a cone shaped left 
lock nut that would allow you to pull the rear wheel in, which would pull 
your frame out to 130 for you.

Hey Jim just to be clear I'm not slamming bike stores. And regarding where 
they make their dough yes just like automotive outfits its the parts and 
labor where they make their money. I've never run a bike store and can only 
imagine the number of idiotic questions plus resistance to spending money 
by some customers. In the case of my LBS I think it's a case of just being 
busy. I'm happy their busy and doing business. I also agree that doing a 
resurectio project can and probably is more expensive than buying a bike 
off the rack but for me the end result will be far more satisfying.

I don't  have any photos  .. lol !!!   The frames I did it on were 531 ST,  
Columbus SLX and an 83 Stumpjumper.  The builder showed me how to do it, 
without tools. He showed me outside his rural shop, in the grass of all 
places !!!  I asked him where his tools were , he siad he didn't need any 
as he's done it so many times .  He did have a tool to check it though, but 
he was spot on the first time .  

Basically you go by feel . If one has no confidence to do this, by all 
means DO NOT do it !!   I had experience in shop doing it with tools, so I 
already had an idea of how to do it, but not with no tools !!  The frame on 
it's side, gently pull one stay towards you at a time.  Check it with a 
string test or if you have a large straight edge .  

It's mostly a matter of self confidence, just know you can do it , and you 
do it :)
