Rear axle length for new hardtail

[hillcat]

... noticed the masterlink brushed paint off, just the paint.

Yikes! It may be precise measuring but that's not right.

Yep and if you put many miles on the chain and it will be eating off the metal.............

hard to tell but it looks pinched in to me. measure tubing near the axel plates inside to inside. move up about a foot and measure again. same?

Cinch down one side, then work off other end.

That's the plan, I ordered some spacers off lowbrow, I'll used those and try to line up the rear tire by following FabKevins article.

I'll post the results and see if I my chain will clear

From the looks of this (if I did this right) I definitely want to cut my axle back and have it re threaded. Shouldn't be a big cost I don't think.

I also forgot to account for the brake caliper bracket, but I have enough spacers to make it work.

Also, question about the chain. I'm going to need a longer one due to the stretch (3.75in?).

I saw lowbrow has a chain for 60$, now is it better to buy a longer chain and cut it back or is there a way to extend my OEM chain?

While chains can be extended by adding a piece, and an extra master link, you should not extend an old chain with a new piece.

Best to buy a new chain.

And better to buy a good quality chain now, instead of buying a lower quality no-name ($60) one, then buying a better one, such as another one Lowbrow carries for $100; Diamond 530 Drive Chain - 120 links USA made.

You can figure out the length of chain you need with this calculator; input pitch (5/8 for 530),
# of teeth on sprockets, and distance between centers:

What is the condition of your sprockets... and maybe now is the time to consider changing sprocket sizes to change your ratio to achieve certain rpm for your cruising speed; best life from a new chain is having new chain with new sprockets.

You can use this RPM Calculator to determine your RPM in top gear with different sprocket sizes and comparing with stock, what you have now and options;
