The plan was to build a fully-useable, winter hack / everyday bike. I've built a Kona Cinder Cone that tips the scales at a fraction over 24lbs. But I want it to be lighter :( However, I think although I could add titanium crank bolts and a few other minor ti bits, the majority of 'excess' weight now lies in the frame. I.e. if I went carbon or titanium I'd lose 1-1.5 lbs. Take a look at the specs below, is there any further weight reductions to be had for a reasonable sum, short of buying a new frame?

Lots of little ti bolts on Toronto cycles - not going to save you much though :lol:

Out of interest - What are your frame, tyre, tube and pedal weights ?

WD :D

Forget that, just buy some lighter pedals all in
Current ones are about 360g so quite heavy in comparison

Buying a 300g or less pair would drop it below and will drop more for quite a bit less than other methods.

Given you have XT and Ti/Carbon upgrades, pedals are lagging behind a bit ;)

grip shifts will save a load of weight, 1x9?

Pedals eh? But only a 60g weight reduction? Working on £/g that's a lot of money.

Frame weight is about ~1900g I think. I had an 18" version of the same frame which was ~1800g, so the 19" will be a tad more than that.

Tyres: ~470g (claimed)
Tubes: ~140g (internet)

Have a big poo before riding and don't eat as much?

I have built super light bikes before but they were all hampered by a rider that cannot say no to beer and kebabs.

Food for thought? Or not as the case could be.
