Well you could almost save a kilo right there!

I run these at 1600g on my all mountain rig, you could get lighter ones for XC'ing.

I have the same rims built on 32H Hope pro2 Evo hubs with DT Comp spokes. 1700g with tubeless tape and valves fitted.

what decent lightish all rounder tyres have good recommendations? would like a fairly simple winter trail tyre, not a real mud plugger, but something capable in wet conditions.

REAR-WHEELS-DISC-HOPE
•Rear Hub Hope Pro 2 Evo 135mm Quick Release
•Rim ZTR Alpine Black - Disc
•Spokes DT Revolution Silver


FRONT-WHEELS-DISC-HOPE
•Front Hub Hope Pro 2 Evo Disc - Quick Release

Hans dampfs? Not exactly light but not super heavy. Good grip in all the conditions I've tried including the bog fest here around the south downs - havent had to put on the mud tyres yet and they were awesome at Swinley today.

I've started an upgrade path on my '09 ReignX1. I got very very tired of schlepping up the hill a few weeks back. Back to the Maxxis ADvantage 2.25 front and back with XC tubes. Saved a kilo and a half or so from taking the DHF dualply with DH tubes off the front.
Then I sourced a DHX 5.0 air shock, and after a painful little issue involving a steel bolt in an aluminium frame, that's another 3/4 kilo dropped. The DHX3.0 with 650lb spring was fairly heavy and the new shock is quite a bit lighter..

Next year will be a swap of fox 36 airsprings instead of the fox 36 with stiff spring that is on the front.

No scope really for lightening the wheel, they're already a lightweight rim. Only thing after that is to go to ghetto 1x10 as I've been told that the drivetrain is worn enough to need replacing, and if I have to replace everything then I may as well do the proper upgrade.

The funny thing is it's currently still heavier be a few hundred grams than my 10" coilsprung Santacruz V10.4. I'm not going to do a lightening project on that for some time, as I don't have the funds to go air front and back on that bike.

Wow some heavy bikes here. I thought my steel framed Orange P7 hard tail was heavy compared to my road bikes at 12kg. Its the forks added most weight compared to when new Pace RC7 carbons felt like they doubled the bike weight when fitted!

Just remember though MTB bikes need strength so its not all about weight like a road bike. I got through 4x XTR rear mechs in one year until trying XT. Small weight penalty but twice as strong IMO. Middleburn cranks saved many grams over Shimano offerings albeit wallet emptying but seriously strong so its worth playing around with kit.

I'm now seriously considering removing Pace forks for original for full hard frame set up - back to basics

My 2014 Stumpy FSR Evo weighs in at about 29lb's, that's with a pretty much standard spec save for the 1x10 kit and high roller exo's rather than the spesh tyres.

For a 6" travel bike, in size large, I think that's pretty good. Climbs as good as anything mtb I've ever ridden, and descends more than well enough now that I'm too old and scared to ride DH bikes any more!

My last mtb's have felt heavy, had an ally hard tail and a trek full suss and both of these have been approx 28lbs, but I purchased a carbon full suss this year and it weighs 22lbs (10kg)


Strange though as I actually prefer bikes to feel more sturdy, they seem quicker to me. I spent money on a road bike which was 13.5lbs and I hated it, I sold it after 6 months, I now ride one which is 15lbs and I get on much better with it.

I'm considering buying a Bird Zero 1.0 in the New Year.

It has a claimed weight of 12.2kg/26.8lbs - which to me seems a bit on the chunky side. It's an Aluminium frame with 1x10 XT/Zee gearing and a Reverb seatpost. I'm really not sure how favourably such a figure compares with the competition. Anyone have any thoughts?

I say "seems a bit chunky" but it's a real lightweight compared to what my current bike weighs in at. My 2008 GT Avalanche 3.0 is around the 14.5kg to 15kg mark, as ridden. I think I've been too hung up on weight when considering a replacement though. I've decided to limit myself to bikes on which a proper test ride is available, and to simply buy a bike which rides well. Any retailer who is not prepared to let me have a proper off-road test ride which lasts more than an hour gets chalked off the shortlist. This is good, because the chaps at Bird are so confident that their bikes 'sell themselves', that they positively encourage prospective buyers to ride the nuts off them before they commit to a purchase. All I'm really waiting for now is my compensation cheque to arrive from the solicitor, so that I can get on with ordering one. It might, in the words of Bird Cycleworks...

"...Let's not kid ourselves, the Zero isn't the lightest frame on the market. It is however one of the only aluminium bikes offering all the features of a full on trail weapon in a package that doesn't weigh a ton..."


...not be the ultimate in lightweight bicycles, but it is a remarkable component package for the price, and has been rated very highly (and consistently so) by those who've ridden one, and by the cycling press generally. I'm not fretting about the weight alone anymore, and trying to objective about accessibility, customer service, and the bike as a whole package, and no-one else has made as many of the right noises, nor made as good a first impression upon me as the founders of Bird did when I first met them. I'm pretty settled on the Zero now, unless anyone has knowledge of a particularly astounding sub £2000 lightweight hardtail which can be pressed into service in (infrequent) enduro racing and take a reasonable amount of punishment in day-to-day use?

Nice bike to ride, get booked on a demo day down the road and have a spin round Swinley on one.

My current Carrera Fury in all standard trim (apart from CarbonCycles Exotic flat pedals) weighs in at 13.4kg.
Have some different bars and a carbon seat post to fit - hoping to get weight down a tad - closer to 12kg would be nice, but will probably need to change the wheels for that.

Bird Zero 1 looks a cracking bike for the price.
Tempted with one later in the year unless I get a full susser.

I have some X Kings folding tyres on my Trek 8500. Absolutely no grip on any damp surface, and don't try them on wet tarmac, that is super scary.

I've been impressed with Schwalbe tyres run tubeless, first Racing Ralphs and then now Nobby Nics over winter. They're about 600g in the 29x2.2" variety and roll really well especially when tubeless.

Speaking of tubeless, I saved just over a kilogram off the wheels of my fatbike by going tubeless, as each inner tube weighed 650g!! Total cost was about £20 in valves, gorilla tape and sealant.

Bike weights are always a funny one. Some bikes hide their weight well, some don't.

Most has already been covered but the best way to save a shed load of weight is wheels and tyres.

I've got some 29" LB carbon rims on Pro2s that with rim tape came in at 1700g, the standard ones that came off my Gyro were 2400g. Add to that some tyres that are in the 7-800g bracket and not 1.2kg beasts, you'll save quite a lot.

IIRC, my Gyro comes in around 28lbs. Without changing the frame covering it in more carbon doesn't make sense in the £/lb battle.
