I bought some portable luggage scales which are pretty handy for weighing bikes too. I was a bit schocked to see that my carbon commuter (Giant TCX) weighs almost exactly 11kg - a lot more than than advertised "base weight" of 9.2kg. I have a non-stock wheelset (Fulcrum Racing 5 vs Giant PX2), and possibly marginally lighter tires (32mm Vittoria Hyper), so I estimated the accessories to come in at about 2kg.

Here is my breakdown:

Pedals - Shimano M530 - 455g

Lights - Lezyne 800 lumen front c. 200g, Serfas rear 60-80g

Altura KLICKfix bracket 118gr (for bar bag - not included)

Topeak accessory bar 116g . (needed for light when bar bag is used)

Topeak top bag 150gr

Topeak large saddle bag c. 176gr

Topeak Hexus multi-tool c. 170gr

Topeak minipump 82gr

Schwalbe Innertube 28-40mm - 150g

2 x Bottle cages - c. 100g (bottles not included)

Bell - 20gr? (legal requirement)

Sigma bike computer + sensors - 50gr?

Garmin Edge 200 - 65gr

rear fender (SX Raceblade pro) - c. 200gr?

Total: c. 1950gr.

It certainly all adds up!

Some items I would consider absolutely necessary: pedals (duh!), spare inner tube, pump and basic tools (although maybe lightweight versions or a couple of allen keys would do)

Others are normally needed: lights (for added safety even in daylight), bottle cage (& water bottle), bell

And the rest is not essential or strictly necessary, but adds utility: bags (for food, spares, tools, phone, wallet, rain gear), fenders, computers.


I should stress that this is a commuter bike, so I'm not racing it, or going very long distances (about 28km round trip, although there are quite a few hills). I do need to keep the bags for carrying stuff, and if I got rid of them, I'd only have to use a back pack with the same total weight, but less comfort.

I'm curious whether anyone else had gone through the same exercise, and what your total accessory weight is?

If this were your bike, would you be looking for weight savings, and where from?
