I have been working on my Flash for a while to get it down in weight. It is currently on 7,6 kilos and I am still looking for options to reduce weight. As the bike is used for regular XC training and XC racing, I have compromised on a few parts (seen from a WW perspective) as the lightest parts did not seem race-worthy to me in a few categories (this is of course a personal judgement only). The parts ended up being pedals (I like the XTR far more than Eggbeater) as well as tyres and tubes.

The current build list is as follows:

Cannondale Flash 26"
Cranks and BB: Hollowgram SL
Chainrings: XX
Pedals: XTR
Chain: SRAM
Cassette: SRAM XX
Rear Mech: XX w. Ti bolts
Front Mech: XX w. Ti bolts
Shifters: XX w. Ti bolts and BK carbon clamps with Smolke carbon bolts
Brakes: Magura MT8 w. Kettle carbon rotors and black Ti bolts
Handle bar: MCFK carbon
Steertube: MCFK carbon
Stem: AX Lightness 70mm w. Ti bolts
Grips: Extralite foam
Fork: Lefty DLR SL
Wheels: Enve clincher carbon w. Project 321
Seat post clamp: MCFK carbon w. ti bolt
Seat post: MCFK carbon w. Ti bolts
Seat: Tune Speedneedle
QR: Tune Ti.
Tyres: Rocket Ron
Tubes: Michelin Latex

In general, I have tried to change most of the bolts to black Titanium bolts and a few Smolke carbon bolts for low stress areas.

Any advise on further weight reduction will be much appreciated. :D

Thanks for the look. :wink:

Nice bike! Seems both reliable, stiff and light! If you want to get it lighter you can:

Is it possible to find titanium spindle for the XTR? Would save a bit
Change chainrings to Tune or B.O.R. The spider on XX is so large anyway so stiffness is less of a problem than on say a XTR or hollowgram standard spider. Saves around 60 gms
Change pulleys to Roth Sheks. Saves around 10 grams

How do like the rotors? How's the braking?

Thank you for input.

I think I like the CK/I9/P321 engagement type too much to change to Extralite even though I reckon that I could save some significant weight in that area. I am not sure of the engagement type and reliability of Extralite. Any input?

Lighter seat is a valid point - I will look into that.

Ti spindles for XTR would be great. I am not sure if a new version of those is out, because the last version on the market had a tendency of breaking.

EP is a brand i find unreliable, so will pass on the spindle unless I can find an alternative company making them.

Leonardi spider rings is a great suggestion - I will look into those. SI SL2 - I will have a look. For the i link cables I hear mixed feedback. Are they reliable?

I think I will keep the paint - do not have the abilities neither an appropriate location to go into paint removal.

For the Kettle rotors, I have to say I am still in the testing period. Not yet sure if they are going to deliver when the pads have broken in.

I links work fine. They just need to be properly set up.

Yes - it is a bit high. I have always liked my frames on the smaller side, so that is the challenge that then comes along :D

You need one size bigger frame.

You are most likely right, but I prefer the current size :wink:

Take a Delrin Spacer instead the orginal MCFK carbon one. Then change the front MT8 to the good old Marta SL IS 160mm, and you`ll loose weight and 2ti scews and the ugly adapter :)
Tell me more details about your lefty
