from a bike by taking off:
Generic, basic, unbranded centre lock disc wheels
Kenda Nevegal Wire Bead 2.2 tyres
Rock Shox Tora 100mm forks
Shimano Olivio (sp?) Octolink 9 speed chainset
HG50 casette
basic alloy stem, riser bars and seatpost
for:
Hope Pro 11 on tubeless xc type rims
Tubeless Schwalbe Racing Ralphs
Easton carbon XC risers
Ritchey WCS stem
FSA or something nice carbon seatpost
Sram lightweight cassette
XT 9 speed chainset
Rock Shox Reba 100mm forks
Maybe change little things as well like grips, saddle, pedals….
The easy way, I know would be to weigh the parts on the bike to come off and research the weight of the parts to replace them but I don’t yet have the bike in my posesssion.
I’m considering buying a bike that is a porky 31lbs but I only want it if it’s possible to get it down to about 26lbs with the above parts that I’ve mostly already got in my garage.
Thanks

best bet is often to look ‘up’ the range of bikes fromt he same manufacturer and see what the ‘top’ one weighs – you’ll be unlikely to beat that without spendign lots of money.

Think you might be missing the point a bit.

Yeh, you’d probably save that in wheels/tires and forks alone.

Depends on the bike.

Might be economicaly better to flog the pile of bits and buy further up the moddle range though?

You can probably save 2lbs on the tyres.

Maybe change little things as well like grips, saddle, pedals….

Depending on what you choose, you could easily lose one pound plus on the ‘little’ bits. IMO it’s there you can make a difference. Many OEM saddles weigh a ton. The BG jobby on my winter road bike was over 400g, and still far less comfy than a Toupe.

The wheels will yield the biggest saving, however:

Hope Pro 11 on tubeless xc type rims

Is very vague, and could be XM819s, at nearly 500g each, or ZTR Podiums at 290g each, which makes quite a difference.

Difficult to actually tell, some of your stuff isn’t that light (FSA carbon post), but some OEM Toras can be incredibly heavy, and you may save up to 2lbs there alone.

Toras 2400g vs 1650g Rebas = 750g
Nevegal Wire x2 + tubes 2850g vs RR + latex 1700g = 1150g

1900g x 2.2 = 4.2lbs

well on the way

have a lok on retrobike weight weenies for the weight of the new bling stuff, weigh the old stuff, bobs’s yer uncle.

“Think you might be missing the point a bit.”

Care to elaborate?

I could get the bike for a very good price, sell the cheap parts (admittedly for not much money), fit the parts I have and buy the parts I don’t have and hopefully, have a reasonably non hefty bike with nice spec. for not much cash.

This particular frame is double butted, next one up and beyond is triple butted.

Wear thinner socks and no undercrackers that should save a few oz’s.

3rd option……

Buy an inbred or scandal or even cheeper, the brand-x XC frame (also sold as dirty-jo, hansome dog, arrow, etc).

Seeing as the OEM bits are probably worthless, a cheep frame might be a really good bet?

Thanks for the replies.
Looks very doable but possibly not the great scheme I thought it might be.
Thanks again

What do you weigh?

Is it an option to loose 5lbs off you before the bike.

I am serious.

I just dropped 5kg off my belly and it’s made a massive difference. 31 lbs ain’t that heavy… Swap stuff when it wears out.

+1 for losing weight off yourself before worrying about the bike. I hear so many people worrying about minuscule amounts of weight on their bike whilst chugging a beer and ploughing through several packs of crisps.. In fact ride the heavier bike for a bit and then swap the components round -it will feel like cycling on air (like when you’re trekking and take your rucksack and boots off at the end of the day). I’ve got guns of steel from lifting my steed about!

I’d be looking at wheels, pedals, tyre choice, and tubeless in particular.

That whole “lose the weight yourself before you think of the bike” thing is a lot of pish.

I like beer and I’d much rather buy shiny bits than change my lifestyle.

So stick that in yer Acai Berry Smoothie ya bunch of sanctimonious tw*ts.

You weigh 31Lbs?! If you are more than about 6 months old, see a doctor!

The acai berry one is nasty stuff Spin but I’m sure it would help your bowel movements shift all that sh!t you’re full of. I like beer and chips and probably have quite a few more than I should but then I’m not worrying about the weight of my bike either. If a beer belly helps cushion the landing mind don’t bother.

In fairness Monksie you could be as svelte as a roadie in which case I agree- tyres first!

Weight on a bike is different to weight on the belly. But if you cant afford XTR and titanium and nice carbon then go ahead and justify loosing weight from your belly as an viable alternative to the bike weight. But its not the same!

First, weigh everything. Weightweenying without good information is doomed to fail in irritating ways

And for some reason some people think losing weight off the bike and losing weight off you are mutually exclusive- “lose weight off you before the bike”- why not both?

After a fair bit of work I got my 456 down to 25lbs, with fat tyres, a big fork and a dropper seatpost, and decently tough parts. Nothing that hampers it in other words. And it’s absolutely hilarious to ride. Bit of a handful sometimes but I can do things with it I can’t do with my 31lb full suss, it’s just plain easier to move. I couldn’t achieve that by losing 5lbs off myself.

A couple of years ago I lost around 5lbs off a bike and around 21lbs off me. The gains seemed to me to be roughly the same.

I’m always worried about losing valuable pounds when I buy new light weight kit. 😯

Stoner, Racing Ralphs and latex weighing 1700g?

Mine weighed in at 909g + 150gish of sealant.

Both the Use carbon Alien or KCNC seatposts are light and mid priced.
