Bike weight.

I've got a Yeti 575 that's a few years old. This is a 'play' bike so was never intended to be super light. It has zero fancy shmancy parts on it.

Depending on tyres it comes in 12.5-13kg IIRC (although haven't weighed it for years - see above).

The 575 is a 26" frame for those that don't follow Yeti.

When I was looking to replace my XC race dual suspension a while back - before I found out I was broken and had to stop riding off road so much - spec'd a Yeti ASR-C at 9.4kg

I reckon any decent race hardtail should easily come in sub-10kg these days and as above, you've been able to get dual suspension that light for couple years.

Ibis Mojo HD.
26", 160mm front and rear.

Got just about carbon everything, but it's built as a super tough AM bike, so the carbon parts aren't any lighter, just way tougher.

With heavy DH tires its 13kg.

I'm less concerned about weight and more about ride-ability. If a 2.6kg pair of DH rubber can give me a 2mm wider smile, it's totally worth it.

9.7kg.
Thomson masterpiece.
Tune hubs on Stan's crests 1388g
Selle italia carbon railed slr saddle
KCNC rotors
Ti bolt kit

On a cheap fishermans scale, all large.

10.4kg Ti hardtail running light 650b's, XT, Hope with carbon post & bars.
11.7 Yeti ASR sl similar spec to above
12.1 Pipedream Skookum 29er 853 steel hardtail
13.4 150mm AM El Guapo

I'm 85kg & am skeptical about super lightweight components, I put reliability above ultimate weight saving so the tyres are all running tubeless, ust or snakeskin/protection, the wheels built with brass nipples & the bars are freeride spec rather than SL.
I think that I could shed 0.5 a kilo per bike without this & another 0.75 by using XTR gears & brakes.

That intense is insanely light.

A general rule of thumb would be a high end hardtail would be 8.4-9.5kg.

A high end XC full sus race bike: 10.0-11.5kg.

Full sus trail bike 11.5-13kg

AM bike: 12kg-13kg

Downhill bikes 15kg-17kg

This is what I expect when going high end, but they can get pretty darn heavy pretty quick. I had a glory 2 that was in th 21kg bracket.

I have a 26" Alloy anthem (100mm travel) with fancy cranks and brakes but standard XT wheels. 11.3kg running tubeless.

Alloy 26" reign with Mavic Crossmax wheels 13.4kg tubeless

Specialized enduro 29r carbon fully schmancy 160mm 12.4kg. Although I reckon I will get that to 12dead soon.

If you looking for a really light hardtail 29r then Limited Edition AXX1 from OpenCycle weighs in at 7.3kg/16.1 lb.

With heavy Enve parts and Rockshox SID its 8.3kg

Or general everyday fruit 9.1kg :/

Of course if you can do without front suspension and handle a carbon front fork, it's 6.4kg NP, But if you do want front suspension and can handle 60mm of travel it's 6.6kg NP (NP = No pedals).

PS: those are the weights for large frames

Niner air9 8.64kg carbon RDO fork licorice black ZTR crest rims all XT bits carbon bars & a carbon seat post which take a little getting used to due to the flex

My 2013 Epic 29er is 10.5Kg, S-Works carbon handle bars and seat post. XTR Pedals.

HOWEVER. I only weigh 61Kg.

Last year I was 14-15Kg heavier. That's almost 1.5 Epics!

I'm more worried about total weight. Me + Bike + Water + Equipment = about 75Kg

I still have room to lose another 2-3Kg before the cape to cape and still be in a healthy power to weight range. Just to make it clear I'm only like 165cm.

My Large 26" stumpy evo expert is about the 12.8 kg mark and that was with tubes, i haven't weighed since i went tubeless. I also haven't really watched weight at all on my bike - dropper seat post, heavy wheels 150mm fox float up front but like others have said i'm looking for a reliable, fun rig not a light, finiky speed machine. Although a sub 10kg bike does sound pretty good! Its amazing how much you notice that 500g.

I also dont really care of my weight loaded up - lots of water, tools etc..

Jono.

26er with a practical build
1 x 9 XO
XT brakes and cranks
SID Race forks
Carbon post and bars, tundra saddle
Mavic 370 rims, heavy but unbreakable
Crossmark UST and IKON

comes in at 11.3kg which I'm happy with as it is a set and forgot bike that handles abuse and neglect with a smile. Saving any more weight (wheels are an obvious candidate) would ruin some of that all round usability for me

... but if it was it's backfired. Obviously a lot of people are a bit interested in this

OK, I'll jump in. Both 29ers.

Santa Cruz Tallboy, extra large, mostly X0, TWE wheels, Formula R1, Nobby Nic/Racing Ralphs tubeless, eggbeaters, around 11.6kg. Great for marathon racing. Thinking of going 1x11 which would drop a fair bit.

Also a Santa Cruz Highball, aluminium, extra large, set up for commuting. Old X9 bits and pieces, Mavic 719s on DT 350s, Kojak bags with tubes, DMR V8 flats, no lightweight at around 11.7kg, but handles Sydney's goat tracks with aplomb.

I'd consider these "normal", and not trying too hard to drop weight.

I weigh 102kg. All bikes groan with every pedal stroke. I wouldn't put them through the extra pain of having to be weighed and having it publicly displayed.

the lighter it is , the less likely it would be jumpable . and jumps are the fun part about mountainbiking ..

all these sub 10kg bikes are just road bike with knob tyres .. they good for fireroads, and a few bumps.

if u own something like that id suggest steer clear of FUN trails like lancaster, gungin descends , and luvin shovels.( or hope your frame is still under warranty )

my bike weights

specialized stumpjumper carbon 29r 13kg even
specialized stumpjumper evo alloy comp 26r 13.5kgs

the best part is passing people on climbs while they grinding away on their sub 10kg HT , while im on a 13kg dually and enjoying the downhills from all that hard work i just put in getting to the top.

fitness eats bike weight( within reason )

if you around the 10-11kg for HT
12-13kg dually id say they about ave weights

I'm obiously at the lower end of the budget spectrum but my well loved "Ye Olde Commencal Combi S" hits the scales at 15kg. If I was lighter and richer it might be a big deal but since I'm 105 kg and a liitle need of some milage old faithful will do until I win lotto. The old beastie handles Manly Dam a lot beeter than I do and for a 100mm travel bike it is built like a tank.
The only fancy parts I have are a pair of Mavic Crossride wheels which replaced my original pretzeled ones.

LOL 15kg !! for a full on 6" trail bike.
Its been built to take abuse not win XC races but saying that I've done a couple of 12 hour enduro races in the UK with it.

26" 2008 Reign, std except UST wheels and tyres, 13.4kg
