Nice!

That's a sweet ride! I hear that Ti-Springs make the suspension feel a lot better than with the normal steel spring. Have you ridden it with that spring? If so, I would be interested to see if you feel a difference in the way the suspension feels. I'm thinking about upgrading to a Ti-spring on my Iron Horse.

On of my friends have an M1 with a Ti-spring, and it does feel better than some of the other M1s I have ridden.

Nice ride...now we need some action pics... :)

If you've never broken or bent a BB, running a giga-pipe DH might be a bit of overkill. I'm not going to tell you what to run, but there are lighter options and categories...although the Sunday runs a pretty specific spindle size and choices may be slim.

These are two areas that will save some weight.

I wound up with the FSA 85x133mm BB due to a mix up and it turns out it is about 90grams lighter than the Truvativ.

Also go tubeless. The Mavic Ex 823's I am running are about 70 grams lighter each. A UST tire is about the same weight of a conventional DH tire and you can drop the weight of a tube (250-700 grams depending on what type you use).

Anywhere between 450-875gram weight savings.

taking the stickers off the dorado should save some weight and make it look better
Thats not a good idea. The stickers add a little bit more imapct protection to the fork. I have personally wrecked a pair of 03 doraods from a tank slap so the carbon is torsionally strong but doesn't have good imapct resistance. Leave it the way it is. Make sure you run bumpers with the fork.

The carbon DH bar is only 10 or 20 grams lighter, not worth it IMO. And unless your a light guy a XC carbon bar on a DH bike is not a good idea.

Don't get too hung up on the ultimate weight. Try to minimise your rotational weight though.

From the look of it you are running 2.7inch tires? If so use 2.5inch tires, there is around a 220grams differance per tire and with the sticky compounds you don't really need a 2.7. Use xc tubes as well. Check what cluster you have as well, there is about 150grams differance between an lx and an xt cluster.

tubless will save you alot of weight and money, also do you need a guide and bash system becasue just a boxguide with no bash might save you some weight there, otherwise snap a light weight XC ring inside your guide because you have a bash protecting it...

and seriously, a homemade tubless system will save you heaps in stationary and rolling weight so much so that you should not pass it up if your concerned about weight...

but thats a sick ride man, super jealous, have a good time on it...
