[Closed] Who has the lightest full suss bike on here?

What does an average FS bike weigh these days?

I will say that, IMHO, bikes are pound for pound (that's £ rather than lb!) heavier than they used to be and that manufacturers chasing "low and slack" seem to be far less worried about weight than they used to be. Got to your local LBS and pick up a couple of £2k enduro bikes and you'll be amazed at how sturdy they are.

You [i]can[/i] buy lightweight FS bikes if your pockets are deep enough, and you can obviously build them yourself, but don't assume that a modern FS bike will be lighter than its predecessor - this is very much not the case.

A case in point would be the glorious HB160 - £7,500 of UK-made magnificence and unquestionably a candidate for bike of the year. And yet, it weighs 14kg (over 31 pounds) which is hardly svelte. Perhaps we punters don't care about weight anymore...?

Apart from having mudguards my 2007 5 is the same spec as the one pictured. 150 travel ,2 chain rings and no dropper.
Just goes to show how lucky we are that manufacturers can easily shave 6 lb off a bike.

I weighed my bikes the other day, the HT which is a KTM Myroon with fox 32 SC, 1x11 XT / SLX and Mavic XC421 on SLX centre lock hubs with Vittoria TNT Barzo & Peyote tyres & OE alloy finishing kit and it's 11kg on the nose with pedals, 2 cages and Exxposure light bracket.

My FS, a KTM Scarp Prestige with RS1's 1x11 XTR, DT XR331 on 350's with Vittoria TNT Barzo & Mezcal Carbon finishing kit and it's 11.8kg with pedals, cage and tool caddy on there.

Light enough for me, but scope to drop a kg off each with lighter wheels and finishing kit, not to mention if I swapped to SRAM cassettes2

Weight definitely makes a difference, some of the numbers being banded about seem a bit exaggerated - although I can believe a different heavier bike with draggier tyres would make far more difference than the weight would suggest.

Also, it might not matter that much how quick you get up hills, but since I've started worrying more (within reason) about weight and speed of tyres etc. I can get another descent in in the same amount of time on my local ride (it's more down to the tyres really - not saved much weight particularly as I've gone 29er too.). But again got to keep everything within the limits of something that'll be fun on the descents.

I've got a magic set of scales ...

I had a c28lb 2006 orange 5 once. But I think my bathroom scales were plus or minus 4lb, so it could have been 32lb. That was the weight-weeny set up. Once I added big tyres and my usual coil fork, it must have been a few ounces heavier. Lets call it 29lb.

My 2007 5 was 26lbs at its lightest, but that went up to 27lbs with bigger tyres for most of its life. Wasn't too hard or expensive to achieve, but could've done with stiffer wheels. Probably spoke related.

anyone else remember that issue of MBUK - probably around 1993 - where they took a wheel rim and drilled 10mm holes in between each spoke, all the way round, to see how much weight it would save?

The answer was, bog all. But there was, unsurprisingly, a substantial loss of strength... 😆

I do remember a MBUK where they profiled a young xc rider who raced an orange 5. His was c 26lb with mavic slrs, xtr, floats etc.

My (2014) Anthem 29r amazes me. Not ultra light - mt zoom bars, bonty rl stem, kcnc post and XT 1x11. Just spent and hour swapping to winter setup tyres on both bikes and thought id get the digital scales out.

I weighed myself as im dressed 3 times. Then same again holding the bike The Anthem comes in dead on 26lb and thats with 1900g wheels on, cage and pedals e.g as id ride it.

Now at 120mm and 68.75 ha with an offset bush, i should probably stop looking at new bikes!

I can't believe I missed this at the time!

Yeah, I had a Top Fuel at 19.89lbs with Rocket Rons (and remote lockout, and bottle cage, Garmin Mount etc), was lightest with Furious Freds obviously (19.7lbs IIRC), but they're cheating.

Forks were unaltered, I did take the MoCo out of previous Reba World Cups on an Epic and on some SIDs on my Superfly, made no difference on the former, ruined the latter, clearly the 'base' tune changed.

There was nothing overly scary on the Top Fuel IMO, yeah I wouldn't want to do lots of 5' drops to flat on it, but it was an XC race bike, and it did that very well. Did some 3' drops on it with no issues. My skill runs out there. Ironically it met its demise when the aluminium bit of the chainstays cracked.

My Turner Flux Build.

Totally not my kind of bike, but this 17lb Scott Spark seems pretty impressive, and still quite usable, to me:

Probably drop another pound if they took all the stickers off the wheels.

So i definitely think weight makes a big difference, far more than losing 3kg body mass.

So you are saying that an overweight person riding a bike 3kg lighter than their usual bike, will go up hills faster than if they lost 3kg and rode their usual bike?

I'd argue that besides the identical power to weight ratio, they might have gained some fitness too...

I remember someone did a test.. Rode a bike up alp dhuez 4 times on same power. First time normal, second time with added weight to them, third time with weighted wheels..and once with reduced pressure in tyres

/how-much-time-does-extra-weight-cost-on-alpe-dhuez/

The third time was slowest, so yes it makes a difference, at least the wheels do.

Edit.. Actually that's not answering the question as the weight was added to the bike rather than the person. Interesting all the same however.
