With your keen weight saving eye, I wouldn't mind your advice on this build http://www.crell.co.uk/?p=350
I'd assumed I'd get this to 19Lbs but it's currently on the scales at 20.5 Lbs. Hypothetically, If you were going to take some more weight out of it, where would you target? All my bikes are SPD so the pedals have to stay. Tyres are another area where I need some grip and mud clearing ability so again can't go too silly in this area also.
Other than that what would you target and in what order?
Pretty bike! I have never seen a Whyte bike in person yet.
Personally I would go with smaller diameter rotors. 180/160 is pretty aggressive. True it improves modulation, but with your carbon hardtail I doubt you will be going down 10,000 foot decents for 2 hours. You can really save some weight by going with smaller rotors. The pro3 hubs use the 3 bolt rotors right?
Then I would try some other tires. I too have been a long time schwalbe user. But I feel that as of today they have lost their edge to Conti. The new contis (Race King 2.2 and Mountain king 2.2) Supersonics blow the equivalent schwalbe tires out of the water. That and the contis are consistently lighter than the Schwalbe.
Then I would go with the Shimano Yumeya SP81 cables in white. It would accent the white logo on your bike and save some weight over the gore cables. In my opinion Shimano housings shift the best.
You should try some silicone foam grips from ESI grips. http://www.esigrips.com/Silicone_Grips_ ... orbing.htm
I too was an Ergon user, and I wanted lighter and gave these guys a try. They absorb vibration very well. I like them a lot.
Then I would see about tuning the bolts.
-Aluminum bolts for shifter levers, brake levers
-Aluminum bolts for bottle cages
-Aluminum bolts front derailleur clamp
-Aluminum bolt for headset preload cap
-Aluminum bolts for jockey wheels
-Aluminum bolts w/ loctite for chainring bolts
-Aluminum bolts for disc brake lever reservoir caps
-Ti bolt for seatpost clamp
-Ti bolts for stem
-Ti bolts for rotors
-Ti bolts for cable pinch bolts on the front and rear derailleur
-Ti bolts for disc brake caliper to frame
Other than that, it looks like a solid build. To go lighter you would need to start ditching perfectly good parts in favor of lighter ones.
By doing the above you might lose 1/2 lbs to 2/3 of lbs.
I might have tried harder to source a Cannondale SiSL BB30 crankset in black. It would have been lighter and stiffer than FSA crankset.
