Brighter-Lights Posted February 16, 2011 Posted February 16, 2011 Ali Frames are normally lighter and cheaper than carbon and last longer. Rarely lighter...some carbon frames however are as heavy as alu frames, but the avg. carbon frame weight these days = +- 1kg-1.2kg, the avg weight of a light alu frame is around 1.4kg-1.5kg. - the days of super light alu frames like the Orbea Kilo are gone... Check out the light-bikes.com builds and get an idea what parts to use, some of those are build really light with so so parts. Some older frames like the Giant MCM Carbon's are cheap secondhand and very light. My hardtail was 9.5kg with LUST tyres and x9, XT, AMC, EC70, KCNC, SLR 135, Juicy 7 mix... But I'm on a Anthem X0 now, 10.5kg with light tyres (450g), and the bike is faster, even though I'm feeling the extra weight on the climbs, the lighter tyres are faster and they don't take hard hits with the fully so I have been using them without issues, even in Attakwas.
Azonic Posted February 16, 2011 Posted February 16, 2011 My (now retired) Trek 8900 was in the region of 9-9.5kg, with a 1.6kg frame. KCNC seatpostWCS stemPRO Carbon barsFoam grips (huge weight loss for little money)X9 shifters / X9 JockeyRace Face Deus XS CranksRock Shox Judy SL (with Englund TotalAir cartridges = Lighter than SID)XTR pedalsStandard AM classic wheelsContinental Twister SuperSonic tyres (350g each) Trick is to get light wheels and tires. Foam grips help allot. Can loose like 80g easy.
Weight Weenie Posted February 16, 2011 Posted February 16, 2011 Ja the no-name frame is too heavy to get to 9kg with cheap stuff IMO My GT zaskar (a heavy carbon frame like the no-name brand ones) is 9,2kg -SID WC, XTR, R1 Brakes, ZTR Podium wheels (1210g), Aspen tyres, KCNC, SLR saddle Eggies etc.
vanniri Posted February 16, 2011 Posted February 16, 2011 My no name frame was 1156g... Before it broke?
Brighter-Lights Posted February 17, 2011 Posted February 17, 2011 Before it broke? It didn't break - It's perfectly fine. Carbon is a lot stronger than most ppl think. A friend is doing his 5th year on a self built carbon frame...
cwfourie Posted May 26, 2011 Posted May 26, 2011 (edited) I am going to buy me a Volcan XC pro hard trail frame, it's 1.2kg. Have a full XT groupset 2011. (brakes to leavers everything xt)Going to get a kcnc seatpost stem, and handelbar.2009 mavic crosstrail rims, larsen tt tyres?Fox frl 32 100mm trave; 2011 model.Would the bike be under 10kg?

Topwine Posted May 26, 2011 Posted May 26, 2011 I've ordered a rigid carbon MTB disc fork. I'll lose 1kg at minimum and I like to ride with my air fork at locked out anyway. I've read many positive reviews about the new rigid carbon forks.

Eish, I dont think so hey...I've got a heavyish frame (1,6kg) but most of my other stuff is light - full KCNC cockpit, ESI grips, X0 gripshifters + RD, juicy carbon brakes, alligator rotors, reba fork, american classic wheelset and racing ralph evo non-ust tyres (running tubeless tho). I think mine comes in at about 10.4kg at the moment... I think your biggest problem is your wheelset and tyres - if you lose some weight there you could go below 10kg

If you only look at grams/cost - Look at the Travativ Noir Crank (can pick it up new around R2900 - just check weight difference over nex XT crank)Go for Notubes rimms, (Alex rimms are also good value)Light spokes (double butted maybe)American classic or A2Z hubsLighter tyres (450-600grams)Only rimm tape in tubless conversion.Look quarts pedalsUse XT cassette (11-32 or 11-34) my tips Edited May 27, 2011 by Mellow
RaeTrewBrowne Posted May 27, 2011 Posted May 27, 2011 my hard tail weighs 8kg's but it can't really go off road cause it's a Triathlon bike
Eldron Posted May 27, 2011 Posted May 27, 2011 Apparently the new Momsen carbon 29er HT is a smidgen under 9kg - price tag is R45,000... Pretty good value to weight ratio I reckon.
Thumper Posted May 27, 2011 Posted May 27, 2011 (edited) I wouldn't trust a no name carbon frame, definitely not one in the 1Kg range.Take a look at the Swiss Power boys, 8.6KG 29r .. most drool worthy!http://28.media.tumblr.com/tumblr_l7l9rcQYuo1qd8kd7o1_500.jpg Edited May 27, 2011 by Thumper
