Hi Guys,

Have been reading WW for some time now but never posted anything.
Anyways collected my new bike last Friday, I'm delighted with the handling and paint job on the bike but would like to get it down to 6.8kg at first and see where ill go from there.
The Bikes current weight is 7.8kg which I was a bit shocked at as I thought it would be a bit lighter.
So here are the spec and weights of the parts I've got on it. Sorry I'm not the best mechanic so I haven't removed any of the groupset other than the cassette so ill just have leave it blank. I also dont know the frame weight so ill have to fill in later, not great for my first post...!
My question is what parts could I change to achieve my 6.8kg goal without costing myself an arm and a leg and also keeping the bike robust enough to cycle a couple of times a week?

Frame : Dolan Ares Frameset (Cant strip the frame at the moment) ????

Have a look at different tyres and tubes. For example the Michelin Pro Race 3s I use weigh approx 200g ea and the Michelin ultra light tubes are 72 - 75g each. That saves approx 300g for around £60.
Also check the listings for a seatpost. You should be able to save another 100g there.

+1 on what 585 said, do those first, then handlebar and pedals could save you another 200g.

Just purchased a blackops carbon/ti seat post, suppose to be in around 180g so that should hopefully drop the weight by another 100g. Also going to look into the tyres and tubes for another cheap but great weight saving purchase. Thanks for the advice.

When you get the seat post there will be a minimum insertion line on it. Measure how far this is from the bottom of the post. Once you have the saddle height set correctly put a strip of tape on the post flush with the seat collar, remove the post, measure down from the tape the minimum insertion distance and then cut the post at that point. An additional weight saving for free.

According to the Dolan website that frame in a 48cm is 1200g

I presume this is without the Forks weight included? I'm cycling a 52cm.

1200g with forks would make the frame about 850g with 350g forks which is too light at this price point, so I would say that it is the weight without forks.

The fact that the bike as a whole is not that light despite mostly reasonably light parts also suggests that frame and fork can´t be too light. The obvious place to save weight is the wheels but then you have to go tubular. If you want to keep riding clinchers 6.8 seems hard.
If you really want to build a light but solid bike I think you have to get lighter frame/fork.

Great looking bike though. If you like the ride I would get some nice tubular wheels and not pay lots of money for small weightsavings like handlebars and stuff.

Ok so just did my first 110km ever and must say I thought the bike was great. Managed the route in round 4.30hrs which I thought was ok considering it was very hilly. My black ops seat post(350mm - 190g) arrived just in time. But unfortunately I had to add 2 new bottle cages @ 24/25g and also a cycle computer so weight loss was negated. Gonna purchase a new set of Michelin Pro 3 tires with lighter tubes at the weekend so hopefully get 300g off the bike.

Made a few changes to my bike. Removed the BB30 to English thread adaptor from my frame and swapped my GXP Force Chainset to a BB30 Force one. Dropped the weight from 7.5kg to 7.37kg, not too much of a difference but it didn't cost me much. Changed the saddle to a San Marco Caymano which was suppose to be 165g, turns out its really 190g. Also changes the tyres and tubes. Heres the my full new spec and weights.
