And dove in, head first, to my first single speed. Oh, and it's fully rigid too. Here's the result:

First ride this morning (in the dark, for the most part). Umm... Wow. Fastest lap I've turned in a long time, in spite of the fact it was a brand new bike, I made a couple of stops, and it was dark. I'm just a little bit hooked, I believe I may have seen the light.

So, one little question. The chain was relatively taut when I picked it up from my pals at the LBS last night. It's a little bit loose now (not a lot, but it isn't all the way taut like it was prior to being ridden. I assume this is relatively normal, but how slack is too slack?

Is that a Stumpjumper? Nice.

Here is one of many articles on chain tension:

Yep, it's a Stumpy. Thanks for the link to the article, exactly what I was looking for.

If the chain got way loose on the ride, check to make sure the EBB hasn't slipped.

Also, have you weighed the bike?

Nice!! Welcome to the fold.

Nice build. I sold my 575 18 months ago to get a One 9 and as nice as it was I've never missed it.

Yep, I can see how that could happen. I've got an Air 9 frame I'm about to build up 1x9, part of me is wondering why bother...

Damn nice bike man! Love all the red

 

[Just J]

Lovely! Well done for seeing the light!

 

[BunnV]

Definitely nice.
It's amazing how that Niner carbon fork goes so well with other brands of bikes.
I want to build a 29er just to get one of those forks!
Awesome build, congratulations. :thumbsup:

Nice look'n bike there !
In the beginning I was tightening my chain every few rides, now very little.
I went from stock 21 to 18 and now 17t cog and acceleration is still very very good.
If you start getting the dreaded rear rotor noise, you can try an alligator....not as powerful as G3, but nice'n quiet
