Welcome to road bike weight game info and discussion thread. This is for weight watchers, but be aware, it'll violate your bank account when you spend to make your bike lighter.
All the components listed for road (in relevance to this thread) HERE.
All parts listed are mostly expensive, but there are cheaper alternatives, so enquire within the thread.
-EASIEST WAYS TO DROP WEIGHT- (In order of price low to high)
There are ways to drop weight off of your bike. But your frame is an important factor when it comes to doing this. You don't have to spend a lot of money on a road frame if you look around. A lot of alloy frames are 1500grams nowadays, such as Kinesis. I point out Kinesis as I have experience with their frames, which are low cost for the weight.
If money is no object, you have all of the options available to make a light weight bike.
1) Bolts are an easy and cheap option to save weight, but they'll only drop an insignificant amount, they should be used with another component, unless your bike is ont he scales to being light as is.
2) Headset spacers are another option. Especially carbon spacers, or CNC'd alloy spacers. These can also be used in the same terms as bolts.
3) Stemscan be a cheap upgrade to save weight and you can get cheap ones which are alloy, or even carbon.
4) Tyres and tubes are a cheap option, but you have to sacrifice puncture protection with proper tyres. Latex tubes are lighter by a good margin, but again, you'll have no puncture protection.
5) Chains are various prices, but also another way of dropping a few grams. You need to be looking at high end chains like Dura Ace etc. for decent, light chains.
6) Bottom Brackets prices can vary, but you can spend a half decent amount and lose a good lot of grams by changing to an expensive one, also giving you more durability.
7) A saddle/seat can help too. Lighter, thinner saddles, like Fizik can be acquired for a fair amount, but will be more comfortable on long rides.
8) Pedals are an expensive component when you want light weight, but remember you pay for quality.
9) Seatpost is a good weight saving option, I'd recommend carbon, as it soften road buzz (road vibrations) YOu can acquire a good and light seatpost for around £/$50-70.
10) Bars which are recommended by me to be carbon retail in the £/$100+ price mark, but are worth it in the long run. Cheaper ones flex, and should be avoided.
11) Brakes go into a pretty expensive price range when you want decent power with light weight. You can get low priced light ones like Planet X CNC versions with Swissstop pads for a good price.
12) Crankset is an expensive component, but if you have the money, go for a carbon one, like SRAM Force, although alloy ones can be just as good.
13) Fork You need to spend a good amount on a fork for low weight in today's world, but you can pay under £100 if you want one which is light around 550+ gram mark.
14) Wheels probably on of the most expensive upgrade, but also can be low cost depending on how light you want to go.
15) Groupsets are an expensive upgrade too, which is why I put this last. You will be paying a good amount for a lightweight groupset, but anything in the 105,Veloce,Apex range can be a good weight, but ranges around £/$500+
Anyone think I can get my Giant Defy 4 (23lbs/11kilos in weight at the moment) down to a good weight with a good pair of wheels and parts? I'm thinking of keeping the 105 deraileurs as they're light enough. Maybe a D.A cassette etc.
Now I'm single, I'll have a lot more cash to spend on myself, so I'm going to spend a good bit of money to make my bike light.
Just left you a comment but here is a list: Aim for 1500g wheels or so replace the 1200+g fork with something under 400g no need to drop cash on a dura-ace cassette 105 or ultegra should be fine for now Light crankset would be helpful Tires are huge stem/post/bars/saddle all adds up a lot
Wheels would save 1950g (if they are indeed as heavy as that spec sheet you have claims) fork would save about 850g thats 2800g or about 6lbs lost just for those two
I say build wheels and save some cash....light hubs on IRD cadence rims and dt competition spoke (14/15 butted) should be pretty damn light and affordable, plus with the right spoke count will hold up to training miles and you can still race them if you dont want to buy a seperate race set.
Definitely replace the seatpost with something that isnt an anchor Stem: Go with the syntace F99 (99g if you swap for Ti bolts) Bars: I like alloy, not carbon. So I'll suggest what I ride; syntace racelite 7075 (220-230g dependent on size) Dont go for the spoon...Try fizik or selle italia, there are some very light, yet very comfy saddles out there I also say get something lighter than that 500g giant fork...some of the ebay carbon ones are very affordable and 380g uncut (claimed) or you can search around and aim lower if you have the cash (Scott has some light forks you could sand the paint off of and clear coat too) Aim for 250g about on a training tire The stock headset probably isnt too weight conscious either
Then the small things add up for weight...cages, skewers, expander, pads etc. are good final touches to bring the weight down
James, do you know of any popular rims (but most importantly) sold in the U.K? I can't find any of the rims you suggested before here and don't want to mess around with customs/pay silly money for tracked items from abroad.
I'm getting some Hope Pro3 Monos as hubs as someone I know is selling them cheap, so I'm sorted there.
