Chainline Questions for fixie conversion project...
 

Hi,
For my fixie conversion project, I am at a stage to get the
chainline set. Per http://www.sheldonbrown.com/chainline and
http://www.sheldonbrown.com/deakins/...onversion.html, I have
done the measurements and now have the sizes of the spacers i need to
add to the rear axle. I will be need to add those spacers and redish the
wheel.

Now, the question is after i do this - meaning after mathematically
proving that chainline is straight, is there something else i need to do
? If i go to a shop to do this will they be doing anything different or
extra ?

Since i am a rookie in terms of wheel building, i am planning to start
out with a BMX freewheel (singlespeed) and then swap it out and put on a
track cog. is this is a good way to go by ?? I am using a single sided hub.

thanks,
ravi

If your frame is straight, and your measurements are correct, doing the
math is all that's needed.

Definitely not. Start with a fixed sprocket and save your money. Fixed
is more fun. Lots of folks have the idea of starting up with a
freewheel then converting to fixed, but most folks who go that route
wind up never using the freewheel after they've ridden the fixed for
long enough to get used to it (usually takes a couple of weeks.)

great thanks. I think my math is correct, I will double check it before
i put on the spacers and start the dishing...

Ok, sounds good. I will get started with fixed itself and see if i
really need freewheel in that case would go and get one. I fell in love
with fixed gears when i rode one in the local velo. my worry was if i
didn't build the wheel properly, i would end up in a mess.. but since my
front wheel has already withstood ~150 total miles, may be i can take
the risk and start with fixed itself...

thanks,
ravi

make sure it's really straight by using your eyeballs and a straightedge
along the outside of the chainring. Pedaling and listening is always good.
Quiet? Good.

If i go to a shop to do this will
they be doing anything different or
extra ?

They'll break out the lazer chain sighting helmet and kevlar cog alignment
spanners, but after that it's pretty much the same

:P

Good idea imho. I ride a freewheeling single--and though I'd love to have
a dedicated fixie---the practicality of the fw is excellent. It's nice to
be able to coast down hills at mile 30 when you're getting a bit winded.
:) Try both--cogs are cheap.

'Things' have changed but riders and cycling has not. Fixies are the
way to go for an alternative, bad weather steed. Fun, easy, simple,
what else is there?

The ability to get up hills while still cycling (i.e. without walking).
Honestly, I have three front chainrings and on this morning's ride (and
every morning's and every ride), I used all of them multiple times.
