Could you get a super-light MTB derailleur instead of road? They take the cable from the front, not the back, so you could cut loads off the housing. Obviously a trade off with the derailleur weight but worth looking at perhaps?

Edit: didn't realise it was 11speed. Probably incompatible and difficult to get lighter than SRAM Red I suppose.

Y U 60mm valves?

Random ideas from someone who is absolutely not a weight weenie, mostly extremely impractical:

• does seatpost weight correlate with diameter? If so maybe a seatpost shim with narrower seatpost would be lighter (doubtful).
  
• is a narrower steerer lighter than a wide one? If so a 1" adapter headset thing might be lighter (also doubtful).
  
• glue/fix your seatpost in and lose the clamp (almost certainly not worth it)
  
• file down your brake tracks/pads/tyres to the wear limit (might as well file through a stack of tenners)
  
• try to put some cable stops/guides in your bars and on the frame and lose as much of the outer as possible (is this one actually a good idea??? Feed it through the inside of the bars, guide at the corner, then a hole in the bars like normal internal cables. Someone should invent that. Fiddly as hell but could work.)
  
• smaller chainring and a few links taken out of the chain (tradeoff with gear range obviously)
  
• cut some bits off your saddle at the nose or back
  
• I suppose 650b wheels are lighter in principle? Majorly fuck your handling to save a few grams
  
• shorter stem, saddle moved back to compensate
  
• throw away a bunch of spokes
  
  

I'm just here for the engineering challenge

Yeah all of those are bad ideas

That is all well thought through esp

shorter stem, saddle moved back to compensate

I know they're terrible ideas, just flinging some shit to see if anything sticks. Tough crowd

Shave your head.

Shave everything.

Shave your neighbour.

Remove heel rubber from shoes and stick some Velotoze on for your Brighton HC.

I’ve already ruined a BIC shaving the chain. I’ve had just about enough of your nonsense.

You waxed it yet?

Srsly, epoxing the seatpost is a good one, but I want to swap it out for an aero / less snappy one for flat TTs next year.

Easy would be super light cable outers and power cordz, but I didn’t do it when I set the bike up so I’m unlikely to do it now. Getting them at all cheap means ordering from China, so they wouldn’t arrive in time for this season anyway.

Tubs, but I calculated that I’d only save something like 50g on each rim if I got the old Planet X budget weight weenie wheels (if I could find any) and the lightest tubs. I’ve already gone through one £10 latex tube so fuck that.

In sum, I’ve got to leave some marginal gains to be had for 2018.

Aren't those cranks ridiculously flexy? Makes a bigger difference than some grams especially when pushing mad watts innit?

Also congrats on the WIN

S-Works cranks flexy? Extraordinary claims need extraordinary evidence...

Thanks!

According to the Fairlight Bicycles they’re the stiffest they’ve ever tested.

Ahh I probably mixed them up with the lightning ones

I think they’re 50mm. It’s the only length Vredestein latex tubes come with.

No it ain’t. I have 80mm ones. It does look like 50mm is the shortest tho so as you were. :)

On lube, I'm surprised nobody suggested this:

Aside from the advanced formula it comes with a UV torch because Sky worked out people can't be trusted to oil their chains properly. Faff factor sounds high though.

Forgot my aero bars and TT saddle for this afternoons 2.8% with a tailwind 😐

Hulk sad :((

Twigs and masking tape would be considered unsafe I suppose.

Paraffin wax is better
