kandui Posted November 30, 2014 Posted November 30, 2014 My 1,89m frame weighing 86kg (hopefully 83kg by Epic) feels like a climbing machine.Very privileged to be riding this bike.
pista Posted November 30, 2014 Posted November 30, 2014 Hi to all.Yesterday I bought a Cannondale F29 alloy 2. I was super excited to go home and weigh the bike but was quite disappointed when the scale tipped over at 11 ish KG. So now I come to you weight weenies to help me shred a few grams.The bike is currently has :Front wheel: Stan's ZTR Crest on a lefty hub with Rubena tires.Suspension: Cannondale leftyHandlebar : Cannondale handle barStem: Cannondale stemFrame: F29 alloy 2 (2013)Pedals : Shimano XTSeat post : Cannondale stock postSeat : Cannondale seatCrankset :Shimano XTBrakes: Shimano XTShifters :Shimano XTChain: Shimano XTCassette: Shimano XTRear Derailleur: Shimano XTRear Hub :Shimano DeoreRear Rim :WTB frequency race i19 with a Rubena tyre.I think that is about all the stuff that make the numbers on the scale rise. I am going to convert the bike to a 1x10 setup and plan to change the rear wheel to a ZTR Crest.is the rim change worth it, and where else can I save a few grams without having to rob a bank. I would like to keep every thing on the bike aluminium so carbon seatpost and stem is out. Any suggestions welcome.What's your budget? Wheels dude wheels and tyres Then bars,stem,saddle and seat post.

Start with the wheels if you want a significant weight saving. But it will cost you a lot to get it down... 11kg is actually pretty light for an alloy bike
Shebeen Posted December 1, 2014 Posted December 1, 2014 11 kg is heavy for a 29er? Becoming a weight weenie is a one way street,just rude the damn bike and enjoy it.
JXV Posted December 1, 2014 Posted December 1, 2014 On a 29er the bigger wheels and tyres make up a lot of the weight gain over similar 26er but it rolls better and is faster anyway for XC type riding.Those tyres are heavy. About R1500 for new lighter tyres will drop 400g @ about R3.75/g. But the new tyres will be thinner and more prone to damage.Rims are light, its the spokes and hubs that weigh...quite difficult to drop a lot of weight here but since you have low body weight you have some latitude. It is difficult to gain more than 200g and your existing wheels are quite nice already.Changing full XT to full XTR group will drop another 400g but this will cost you about R20k (R50/g) and its longevity is less.Ti eggbeaters will drop another 60g or so for R5k (R83/g)Regardless how wealthy you are it gets silly at some point
Bellscycling Posted December 1, 2014 Posted December 1, 2014 Had a flash Alloy 1 two years ago. Came standard with Sram X7/9 mix. Just changed the wheels to a set of Crest hoops with Tune hubs and Conti tyres and a xx cassette and it came in just under 10kg with all the standard alu bits and bobs. Wheels and tyres makes the biggest difference in weight and responsiveness of bike, but are also expensive.

Then I think I am going to drop about 800gr. I believe this will be the cheapest way to lose that much.
W Smith Posted December 1, 2014 Posted December 1, 2014 What's your budget? Wheels dude wheels and tyres Then bars,stem,saddle and seat post.I fully agree. That rear hub is a lemon and weighs a ton. A good set of wheels and tyres will bring the weight down significantly. You can always use the standard wheels as training wheels. From there onwards decide whether the extra cash is worth it
Bizkit031 Posted December 1, 2014 Posted December 1, 2014 You worried about weight try this for size,I am 6.2ft,weigh 95kg ,bike is 14kg 29er FS but then I do Enduros so the weight helps me down the hill but not up. But bombing down a hill is more my thing then going up. So how's them apples for you.
Ryno. Posted December 2, 2014 Author Posted December 2, 2014 Converted to a 1x10 today and dropped 350 grams on the bike. The shifter,derailleur and 2 chainrings weighed 400 grams and the race face narrow wide 34t weighed 50 grams.
Ryno. Posted December 2, 2014 Author Posted December 2, 2014 The conversion cost me nothing because I sold my shifter ,derailleur and chainrings on The Hub and ended with R100 in my pocket
Bobbo_SA Posted December 2, 2014 Posted December 2, 2014 Without a doubt you need these: https://www.bikehub.co.za/classifieds/115597-velocite-carbon-bottle-cages-incl-water-bottles/ you might just save 10g
KALBO Designs Posted December 3, 2014 Posted December 3, 2014 Going 1x10 you should be able to loose about 300g, plus all the other benefits.
