Aah, so they're spreadsheet weights?
I think it's harder than people think to get under 20lbs - I've still only weighed about 4 MTBs that have done it. Schmiken I'd expect that to be over 20 still based on comparable bikes.

XC bike weight. How low can you go?

Jeez, you lot are mental. I'd snap that lot within 2 minutes!

njee20.
no they are weighed weights in the list line.
thats just the list of parts (all weighed by myself)
the actual bike weights are slightly higher than the spreadsheets weights for all bikes.Posted 10 months ago # -
grtdkad like CP says Crossmax SL are around 1800gms, people above will have sub 1500gm wheels, so changing wheels would easily see your bike to 22lbs. JRA do a Stan's wheelset at 1415gms for £369, so it doesn't have to be silly expensive. Go tubeless ready schwalbe or Conti Supersonic tyres and supersonic tubes, that'll probably bring the weight down to 21lbs. etc etc
This is my setup, most stuff is very def not that lightweight (deore chainrings, SLX cassette, lock on grips, standard Time pedals), but key bits are! frame, wheels, tyres

My 1264g wheels (roughly
) were less than £300 - you don't have to go mental.Jeez, you lot are mental. I'd snap that lot within 2 minutes!
You'd probably surprise yourself, light kit has got far better. The only part with a weight limit is my rims, swap to some Alpines and there'd not be anything, bike would still be 20.5lbs or so - they don't feel as flimsy as things did 5 years ago.
On and on: do you not run a chain guide on the Merida?

I'm rather proud of my new build, at 21.5lbs for a FS ally 29er running 3x9 I think it's rather good
Plus I reckon I could take another pound of it easily if I really wanted to.

No chain guide at the moment. As the Renthal ring begins to bed in (now 400 ish miles old) it's beginning to drop every now and again.
Apparently superstar are going to launch a clamp mounted XCR which will be around 45/50 grams and £16 - I'll probably pick one up.

Bream, It's no good bragging about your bike without pics (especially twice). It might just be a fantasy you're living out

agree on the lighter stuff can be strong. I've got a very lightweight front wheel which is over 10 years old and still going strong despite a lot of abuse. It's now on the commuter, and just keeps going.
Light stuff is surprisingly strong these days.

I've just bodged a BB mounted Superstar one with a DMR seat tube mount - works really well, never dropped the chain, doesn't rub. Needs some alu bolts now I've sorted the spacing.

Haha bream my td-1 ss weighs the same as your fs
as much as i wanted it to be sub 20 Although its built to last i guess with arches, brooks swallow ti , 2.25 ralph snakeskins

This was my lightest geared hardtail build so far:
It came to bang on 22lb (on my scales, not a spreadsheet). That's with a sub-3lb frame, SID Race forms, American Classic wheels wearing Speed King Supersonics and an XTR drivetrain and brakes. It didn't have a particular light saddle or seatpost though, so there were still some easy weight loss areas to target (and I do have lighter bits for that but didn't get around to fitting them) but going much beyond that was going to get pricey.Posted 10 months ago # -

Next planned race will be Snapphaneturen.

Nip into a Specialized store and pick up an S-works Epic. Be prepared to say "crikey".
Posted 10 months ago # -
I forget exactly what they were, but I weighed 2 2011 S-Works Epics, about 21.8lbs IIRC.

still get a bit miffed about these claimed weights myself, but maybe its jealousy?, or cos mine aint as light.

2011 sid xx forksunsure where to save anymore weight, maybe go tubeless rocket rons and save 1/2lb,and lighter chain and casette is another 1/4lb, but TBH, i'm quite happy with it just now and i dont think an extra 1lb would improev my performance too much. Think even absalons bike is 21lb ish, so not mega light

Interesting reading through this thread, it doesn't seem like 1xn Drivetrains have as big an impact on overall bike weight as other major build items like Fork/Frame/Wheels or is that a miss-reading on my part?
Posted 10 months ago # -
I saved about 250g I think going from an XTR M988 Race double to a single ring, it's the LH shifter, cable, front mech and one chainring, plus the added weight of a chain guide.
For me the ratios were spot on - I'd not have done it solely for the weight saving. Fairly irrelevant having a light bike if you can't ride it up the hills
Posted 10 months ago # -
Well that was my other thought, so ~250g (0.55Lbs) is all well and good but only if you end up with a usable (or in many cases Raceable) gearing range... Half a pound at the cost of dropping off the pace on a climb seems a bit of a false saving...
Indeed are there any other "False weight savings" that people have found? Where taking a weight reducing measure has actually made the bike overall slower?

Tires surely, wouldn't like to run furious freds on a wrong day!
Posted 10 months ago # -
I really wanted to try 1x? as I had just built a SS with a 32/14 ratio.
I figured, if I can get that up trails a 32 - 11/32 would give me all the range I need plus the speed on the flats
It wasn't really a weight saving measure, just simplifying the bike.
Posted 10 months ago # -
Also you need to take into account your size/weight and intended use.
My 20" 456Ti comes in at 24 lbs with pedals, crud-catcher and bottle cage; it includes 'proper' tyres, triples chainset, a 5" fork and Ti/carbon everywhere - its equally at home in Swinley, Afan and The Peaks. I could probably save another 1/2 lb, but it'd be expensive...
Or maybe my scales are just pessimistic?

Indeed, and the only times I've wanted a slightly lower gear is while racing. When riding you've always got that bit more in your legs, there's a been a couple of times (but literally only a couple) of times where I've wanted a marginally lower gear while racing. 5th time up the climb out of Medusa's at Dalby was one!

(Mr MC posting)
Do people with digital scales understand the difference between the terms precision and accuracy? I assume when youre that obsessive (and Ive been there it's not a term meant disparagingly) you actually calibrate your scales?
Posted 10 months ago # -
njee20,
What ratio's you running,no problem in xc mtb races ?
Posted 10 months ago # -
36t ring, 11-36 block.
It's been fine 99% of the time. If I'd had one available I'd have used a lower gear at Dalby, on the first climb at Margam and towards the end of Mayhem. Saying that, I've not had to walk up any hills this year, so it got me through, just had to push a little harder than I'd have chosen to!

Cheers, will buy one of those exact frames for next season, so want one for ages and I think you can now get it frame only in the uk.
Dont wanna buy it with sram 10 speed, how much for a chain and cassette which would last maybe 3 big events!!!!!!
Posted 10 months ago # -
You mean a Top Fuel? They're stupidly expensive frame only, I'd buy a whole bike and flog the bits you don't want personally!

The XX cassette I had last year lasted very well, stupidly expensive, but better durability than an XTR. The jockey wheels were rubbish, and I'd not bother to pay for the groupset as a whole, but I'd not shy away from the transmission parts myself. Shifting is obviously personal, I prefer the XTR, and anyone who prefer Avid brakes to the new XTRs is probably on crack

Well that's a right pile of tosh!
XTR cassettes last a year on my race bike, then spend six months on my training bike. Giles Drake went through two XX cassettes last year, and Steve Deas destroyed his in two races (fair enough they were Tour De Ben Nevis and Strathpuffer, but still).
Posted 10 months ago # -
Not IME, I used my XX cassette all year, then stuck a new chain on it when I sold the bike and it was fine - never done that with an XTR cassette.
They're still far too expensive, but mine did appear to last well. The chainrings and jockeys on the other hand definitely didn't last!

Looking at Breams Anthem 29er, thought I'd weigh my FS 29er.No digital scales so only a rough estimate.I stood on the scales at 80 kg picked bike up,90 kg,so bike weighs 10kg or there abouts.
