Ideas to lighten 2016 S-works Crux Disc
Moderator: Moderator Team
I just built a new 2016 S-works Crux Disc.
I am really happy with the bike, but I am trying to find a few ideas to further lighten it-
It is 8.228 kg, or 18 lb. 2 oz.
Stock wheels, 9000 front der. and stock 685/785 Shifters and brakes.
Items changed
6800 GS Rear Der
SRM Spider
Praxis 110mm 34/50 chainrings
SRAM 1170 11-36 Cassette
Zipp SL stem
Specialized Carbon Compact handlebars
Reynolds Ouzo Seatpost
Fizik R1 Antares Saddle
Kenda Happy Medium 700x35mm tires
Shimano 9000 XTR pedals
Here are the items that I am most open to change
Saddle- would consider 00 or Specialized Phenom
Tires- but I like something that is not too slow on the road
Thru axle bolts- still using stock Specialized Labeled DT thru axle bolts
Seatpost- but must be setback- get a Ritchey Superlogic?

Wheels. (if you can find any hubs to fit Specialized's stupid axle-standard)
You might have a look at TiesT bike. He took his Crux to the max.

I am not sure how much weight would be saved, but one option for lightening the disc brakes would be exchanging the calipers with XTR ones (as far as I understand, the Ultegra calipers are similar to XT ones).
What are the wheels? I'd probably start with those, if they are heavy.

Those wheels are pretty light for disc clinchers. I say just ride it and be happy.
You've added some heavier components (i.e. SRM, XTR pedals, VERY heavy cassette and medium cage ultra der). You could spend a LOT of money and not save much weight.
You should really only need an 11-36 range if you're running a 1x setup. Ditch that pie plate to something more reasonable.... you've got a 34t small ring, do you really need lower than 1:1 gearing? I would argue that if you do, then you don't need a 50x11 top gear.

Tune chainrings or Extralite.
A lighter cassette, do you really need 11-36 with double in front?
Thru-axles will be hard as it's not regular axlestandard with 12x100 and 12x135.
Crank Brothers Eggbeater or Candy can save some
I have a set of 1300g tubulars on my Diverge. Tune King/Kong hubs with 25mm Light-bicycle rims. Works with some tweaks
Seatpost check if you can find a Engage Revit or the new "bent" Tune post if you want save weight for real
A lot to do on that bike, my Crux Elite X1 was 7,6kg last week.

His bike is cool but it is a 1x with cantis and AX light tubulars.

I may check out the XTR calipers- that is a good tip.
I really do need the 11-36 gearing and mid cage derailleur. I do a lot of long off-road climbs. 11-12% for 20 minutes- sometimes more.
And I am not a bad climber.
It would be great if Shimano made an XTR level 11 speed 11-36.
Wheels are 1350- not bad for disc brake tubeless wheels?
Does anyone make thru axle bolts that are light for this application?

I'm surprised that it is so heavy.
Which crank?
Did you setup the Wheels tubeless?
I know you said that you need 11-36 but you could really save a lot of weight by changing to SRAM 1190 11-32 cassette.

Specialized crank with SRM.
Yes, I am sure the 11-36 is heavier than Ultegra 11-32 by 100 grams- probably weighs double what the stock Dura-Ace 11-28 weighs.
You guys keep asking if one really needs an 11-36??? Come ride where I ride- you will want an 11-36.
I have many long climbs that are 10-12%- I like those climbs. I don't put along on the tourist paths. My FTP is close to 5 w/kg.
I wish Shimano made an XTR level cassette (or a SRAM 1190) but this is not the case.
I think the next challenge for Shimano is some gravel focused components- a medium cage clutch rear derailler (a light one) and also a light 11-36 cassette.

I ride a 32 + compact in the same area. But I just ordered a 11/36 so that I can get up some of those steep grades I avoid. 11/36 with a compact may not be a bad Idea.
