What if the chain guard brackets included some kind of a plastic guide block to keep it off the white walls?

I am just starting to have this issue myself, Which is why I initially was going to stay away from white walls. But I’m not opposed to chain guides. Particularly if they are invisible.

I am not a fan of chain guides at all. I should be able to handle this with cog and ring offsets.

 

[kingfish254]

Here is the old 18T cog and the new 22T cog. Maybe only 1mm more dish ro it. If need be, I can always use one the big offset ogs that Felt used to have.

 

[kingfish254]

I think I am going with the 48T AMF star chainring. It has a nice offset dish to it. I've always lived these and have actually used them on 3 of my build off bikes, including my first one.

I also added another spacer washer behind the ring just for good measure.

I am already digging this shining star chainring.

Crank up some Earth Wind and Fire

I really dig that crank the shape is really cool. You have a closer pics.

The cranks are from a 3G chopper

The shot over top really shows how long that bike is

 

[kingfish254]

Bike rode excellent. This gear ratio is actually a little better for cruising. I couldn't see, hear, nor feel any chain slop. I'll know for sure after I clean the tires and then go on a few rides.

I like hare backgrounds show through the stars.

 

[Ulu]

I wasn’t suggesting that you needed a chain guide that would rub on the chain all the time. Just something that would prevent a random chain slap against the tire.

It looks like you’re getting a lot more contact than I am. Most of my problem disappeared with an adjustment.

 

[JA331]

This chainwheel suits the bike better than the RF one.

 

[kingfish254]

I like how level the chain stretches out on top with this new combo.

 

[OddJob]

That chain and chain ring combo looks 'tight'.

It is. No slack lines here.

I have decided that i am using the limo fin skirts for sure. Pulled out the rattier pair that I have to mockup. Working on the chain guard placement and new brackets today. It's super hot one out here today.

Those are too cool and the fins look to be a signature of yours. Looking tough!

Thanks. I don't know if they are a signature, but I did use skirts as fins one other time. (flipped upside down on VerBoten).
But it will be my 4th time using skirtguards in 11 years of build offs.
I do like how pointy these are compared to most other skirtguards.

 

[kingfish254]

Got the front chainguard bracket shaped and placed, then marked up the mounting on the guard so that it was spaced properly around the drivetrain and level.

Made a couple of notches in the lower lips of the guard to help avoid any clearance issues with the chain and chainring.

Then I moved on to securing the rear of the guard. Well, I discovered where some of the weight of this frame comes from. The U-shaped seatstars were made from solid rod!!
