One of my bikes is a 2007 Norco Six 2. Supposedly 37.25lbs (probably closer to 40lb)! I'd like to lop a few pounds off without compromising it's downhill/freeride ability too much.
I've only been out on it about 6 times so the componentry is still pretty new and in good condition. And obviously I don't want to spend a fortune replacing too many new parts. Any suggestions on lightening it up based on the following components on the bike:
Marzocchi All Mountain 4 (160mm) fork. Sun Black Eye Rims. Kenda Nevegal Tyres 2.35. Truvativ Stylo GXP Cranks, Bash and BB. Avid Juicy 3 Disc Brakes. Axiom front Hub. Shimano M475 rear Hub. Truvativ XC Riser bar and XR Stem. Titec Seat Post. WTB saddle and SRam X7 Front, Rear and Shifters.
I'd like to try and get it down to 32/33lb if possible. If I change the wheelset (mavic XM719 with DT Comp Spokes), Crankset (XT, SLX Double with bash or Raceface Evolve X Type) and Bars and Stem (Easton) will I achieve it?
Obviously changing the fork would lighten it loads, but I guess I'm looking at, at least £400 for a decent 140mm fork which is expensive considering the All Mountain 4 is virtually new.
Going to XM719s will save you 130g. DT Comps will save about 60, assuming you're starting with 2mm plain gauge. No idea how much your front hub weighs, you might drop 50g going to a Hope. The M475 is a proper boat anchor, you'll drop 90g with an XT or 150g with a Hope. So potentially you've got, er, 390g savings with new wheels. An XT chainset is about 250g lighter than the Truvativ. That's 640g so far, or 1.4lb. Based on that, I conclude that shedding over 5lb is probably not practical. You'd end up replacing absolutely everything and spending a fortune (although you could sell off the parts you took off to recoup some money).
Cheers lads. I thought it would come to that. It's not easy to drop 4 or 5lbs!! The weight is only a real problem on flat trails after 3 or 4 hours. Funnily enough, it climbs ok and descends brilliantly. It's nice to get some weight saving advice for future reference though, so thanks anyway. I think I'll thrash it a bit over the next 6 months and change to a lighter fork, wheelset, cranks etc for next summer. I use my Inbred for local trails now!
My last bike was a norco six two and i absolutely loved it definitely best bike i have ever had for the money, but your right it is heavy - im amazed your out for 3 or four hours on it, that would finish me off....
Upgrading as Mike said is probably financially pointless - when i had mine i used to use my old hardrock for rare all day rides and the norco for smashing around on while i saved up for a new bike
I'm really not that fit. And 4 hours along flat local trails nearly killed me! I've not ridden it since! I love it though as it's so forgiving and comfortable on descents and riding steps in town. I really don't want to sell it as I'd lose out loads. I think I'll do like DM (above) and use it for insanity in the Peaks and use the Inbred as my play time bike!
Tubless as mentioned before, carbon bars, light seat, new wheels and an air shock to loose a pound or more from the spring and air forks but now you are starting to add a lot of cash to a new bike.
I lightend up my coiler primo this way and it is now a pinch over 26lbs and rides like a beut!
