Reduce weight on bike

Taxuser1

Any opinions on this would be of help please

I'm shedding the kgs and would also like to shed the weight on the bike.

I'm riding a FELT F5 from 2010 which I've found quick and responsive and don't want to change the frame.

http://2010.feltracing.com/Belgium/2010-Product-Catalog/Road/F-Series/F5.aspx

i've upgraded to an Ultegra 11 speed drive train on 1650g Graphit Sport carbon clinchers wheels with GP4000s, Look KEO carbons on it.

What would you recommend I change next.

Some of my thoughts on it

Carbon saddle, stem & handlebars, straight fork (more for steering performance), stem, upgrade 105 brake blocks, change bottom bracket, lighter seatpot, 11 speed dura ace cassette ?

what would be the overall weight saving benefit against say me dropping another 3/4 pounds? i'm 159 llbs now, hoping to get down to 152-154 by mid August.

many thanks in advance !

What does the bike weigh now?

Always easiest to lose weight from the engine...

Add some weight to your bike, you'll make the engine slimmer and stronger :-D

The first step down the long, pointless and expensive road to weightweenieism is to buy an accurate set of weighing scales.

I have three, just to make sure.

eeeee

This makes me feel better about my boat anchor (bike). However results may vary. I can neither confirm nor deny the results stated above.

I can confirm 120% more bike envy though. Everytime I get a go on a lighter bike it gets a little harder to love my trusty boat anchor (Henri. I could never say it to his face...he can hear me thinking it though, I think that's why he's slowly falling apart :eek:)

I have a few koms and high places around town on my 13kg commtourer (some of them gained with 3kg luggage extra, when commuting) ;-) When the time comes I will get a 7,5kg carbon one and I'll be flying :-D

Oh, and I came down from 95kg to 81 within a bit more than a year.

If it's the spec from the website, 8.1kg claimed.

That's far from a "boat anchor" op.

Get yourself down to a weight you consider optimal and then worry about the bike.

No point spending €1000 dropping maybe a kilo of bike weight if you have 4 or 5 extra kg hanging off your belly/arse that would be cheaper to shift.

I think he knows that and appears to be doing both.

Nice enough hobby if you don't mind spending.

@Lumen is a man with three scales not like the man with two watches?

8.1 kg claimed alright - with stock wheels and Shimano 105

now it feels as heavy as a Cervelo R3 Dura Ace groupie that a friend rides, and I know I can strip it further so am looking for the little savings.

As for my own weight, optimum weight would be just around 11 stone which would be a stone less than March when i got back on the bike. So that is obviously the major saving for free - all the food money is gone to the bike

The quickest and most efficient weight savings on a bike is usually changing your wheels. Reducing rim weight means you get up to speed faster and better hubs will have less resistance so you hold speed easier.

Saving on weight from groupset and finishing kit will be minimal benefit compare to wheels.

wheels were changed - 1600g set

Seat post, saddle, handle bars stem are your next easiest port of call.

Then crankset.

Last stop pedals, derailluers and shifters

lennymc

how much do you want to spend?

Taxuser1

let's assume cost wasn't an option but bear in mind my first post - i've just gone and purchased a groupset (minus bb and brake calipers) and wheels - it's the add ons that i'm looking at now - whether it's worth it or not

I've a 2011 model F5 which is a claimed 7.98kg on the spec sheet. My bike with pedals and bottle cages weighs 7.85kg on my trusty digital luggage scales. I could drop that weight another 500g by changing the wheels to sub 1500g wheels and use latex tubes instead of butyl but having ridden an F1 with 1250g tubulars and supposedly weighing under 6.6kg I don't see the point as I noticed very little difference in the two other than the slight extra stiffness of the F1 compared to my bike.

I think the biggest gains can be made by losing excess body weight and training harder to become stronger.

If cost wasn't an option I would sell the wheels get a set of lightweight clinchers. I'd start here

edit - but I agree with cjc999 - ride your bike, enjoy your bike, train hard, become stronger.

those wheels are seriously light - never heard of them before
