2015 Specialized Sirrus Expert--lots o' mods
Bought new, decided to mod while still new. The goals were to introduce more CF/reduce weight, naturally. Of course I went overboard; trying to avoid totaling amount outlaid. Managed to trim bike from a shade under 22 lbs to about 19.25-- a lot of it rotational weight. Without further adieu, the list:
Whole drivetrain replaced: 105 cassette and RD are now Ultegra. FD is now Dura-Ace. Crank was FSA Gossamer, now SL-K Light.
3T Arx stem, 90mm. Full unidirectional CF, not the typical CF over alloy.
Easton CF 20mm riser bars
Specialized Overendz CF bar ends to replace stockers
Specialized CG-R CF seatpost to replace stock PAVE carbon
Easton CF wheels. Fawkin' awesome
Zipp Ti skewers
Xpedo pedals
Selle Italia SLR Max Gel Flow saddle
Arundel cage
Whew. I think that's it. So what I retained from stock: tires, brakes, shifters

Looks good. I have a 2015 Elite that is almost 24 pounds. I'm working on putting together a list of stuff to get to shed some weight. Wheels are so expensive though!

Beautiful bike! How do you like the Sl-K lite Crankset? I debating on that or an Ultegra crankset to match the Shimano components I already have. Our bikes look almost the same except I did the CG-R with a Red Phenom Pro seat. Also have A530 pedals on order, I keep nicking my shins with the stock pedals.

Thanks, this helps. Yeah it looks like most of Specialized bikes have a FSA crank for 2016. Keep us updated and enjoy!

Thanks for the warm words AJH, all. I must admit, I enjoy admiring the bike more than I would've expected. As regards the tires: I had planned to upgrade those as well, but I found a number of positive reviews on them and the weight is surprisingly competitive. I decided to live with them and evaluate. It's obviously an easy change down thhe line should I so decide.

Sorry one more question. Would you be able to weigh your old axis wheels?. Next step is wheels and I want to know exactly what they weigh before I decide what I want to spend. On a side note, I went with the Ultegra Crankset and converted it to a 50T 1X, getting rid of the front derailleur and shifter to save weight, I should get it back this weekend.

Unfortunately, I don't have the means to weigh the wheels. There's some info online as to the weight of the 2.0s, however.

Love the paint scheme. Charcoal and red is the best color combination for a bike, in my opinion. I wish I had picked up the 2015 Roam 1 instead of the 2 for that very reason. But my charcoal / green scheme ain't bad either.

Thanks. That's why I opted for it. Could've waited on a 2016 Pro and done less modding but I was partial to this color scheme; although the current Pro is not all that dissimilar.

Wow! It's a whole new bike.
How much did all these mods set you back, if you don't mind my asking.

Very nice and light bike! I have a 2015 Sirrus Elite Carbon Disc with mods and now at 20.5lbs.
Do you know the exact Easton wheel model you got?
