    Flash 1 29'er Frame / Components Weights

    I just built up a Flash Alloy 1 and weighed some components in the process. I was pressed for time, so no pics on the scale, you'll just have to trust me. It was delivered with a slightly different spec than on Cannondales site... 11-34 XT Cassette vs. 12-36, XTR Rear Derailleur instead of XT, and Straight gauge spokes instead of DT Comps.

    The weight list is by no means comprehensive, it's just what I had time to weigh.

    I had a good deal on an XTR kit so I built it up w/ XTR.

    And here's the bike 23.1 lb w/ pedals (sealant instead of tubes)...and one more upgrade on the way:

    Thanks...XX doesn't have the range to work as mountain bike AND a road bike with a wheel/tire change. For trail use only, the 26/39 XX crank would have been ideal. But it just wasn't going to work for how I plan to use the bike.

    I didn't take the decision to put in BB30 adapter to use the XTR very lightly, but there are NO reasonably light BB30 triple cranks at less than $700. Plus, like I said, I got a good deal on the XTR kit...

    my tip is to use a 36 or 37 as big ring and a 24 down to 21 as little

    seen the new XT 10 speed ?

    Were you really delivered such a nice wheel-set with straight gauge spokes? Did you follow up with your dealer or Cannondale to find out why? It baffles me how such an important component would slip through with such a blatant downgrade.

    Regardless, it looks like an awesome bike and I bet it is fast as all get out. Nice build!!!

    Yep, straight guage, I was only mildly dissapointed as I won't be using the wheels for anything but road riding. I had a set of Edge XC, Aerolite, P321&dt240s on the way for everyday trail riding (1408g!).

    Thanks for the props, I do seem to be faster on this bike than any I've had before it... although I haven't timed any of the local time trial loops I use for comparison yet.

    I'm using these on my Flash 1 alloy with the BB30 bearings and a Shimano SLX crankset.

    Thanks for the heads up!

    Those shims were my first choice, but after looking closer I didn't think that the taper would clear inside the small chainring. I'll get some on order...should save about 50g for the assembly, retain the BB30 bearings, and cost only $15.

    I'm attempting to do the same thing but seem to have a gap of 4-5mm on the spindle, basically the crank slides back and forth about 5mm. My LBS ordered me the BB30 in pieces and i'm getting the feeling I'm missing a spacer or something. Can you tell me what you have installed from C-clip out on both the drive and non-drive sides? Nobody around here seems to know what I'm asking and I have this awesome new bike on my stand with no crank

    Wow, 5mm is alot. What specific model of crank and what other parts are you using. Be very specific.

    How much clearance is there between the front derailleur and the rear tire?

    Thanks for the reply. I have an SLX crank, the 2 chainring version. I'm using the Wheels Manufacturing BB30 Adapters and an FSA BB30 that was installed by my LBS. All I have for the BB30 are the two inboard C clips and the bearings. It seems like something is missing.

    I don't have a front derailleur mounted yet, I picked up an SLX down swing somewhere and honestly it doesn't look like it will fit. The tire to seat stay clearance is probably on the low side of 1/2". The frame is an XL but everything sure seems awful tight.

    Well, I have a Caffeine XL 29er and the same setup as you except for a triple SLX crankset. There was a tiny bit of play on the non-drive side. That was fixed with about a .5 mm shim. The shop did that.

    While flash and caffeines are different frames I guess the bb shells should be identical.

    68 mm shell

    I was surprised to see that my flash had a 68mm wide bottom bracke shell, especially considering the width of the stays. What's the caffeine?

    Thread resurrection time:

    To continue this thread, I experienced many of the things that Brentos did: 11-34 XT Cassette instead 12-36. An XTR Shadow Rear Derailleur instead of XT Shadow, and Straight gauge spokes instead of DT Comps.

    The bike was 23lbs and 10oz (23.63 lbs, 10,283g) with pedals and tubes stock. With my changes the bike is now 23.06 lbs w/o tubes, (added sealant), put on a bottle cage and a wireless computer. Coming is an X.0 Rear der, which will drop about 30g, and I am in the market for a BB30 26-39 crank, This Afterburner is a porker and I don't need a triple. I am going to wait for the X.0 because the price of XX is absurd. Any suggestions that are cheaper than XX? I know I also have to cut down the brake cables, please don't remind me. I have the Hope kit on order.

    Since the pictures were taken the bike lost another 39g when I swapped to a Specialized Phenom 143 (231.8g) saddle from the Fizik Aliante XM MG (271.0g)

    i donīt think so

    the alloy models(rize,rz one40, ...) have a complette adaptershell not that little sub cups

    What does that matter? More damage could be done by pressing that BB30 adapter than those plastic cup reducers.

    I am surprised these mildly [EDIT: looking back at my bike, and yours, I think "mildly" was a very poor choice of words] modded Flash 29'er 1's weigh approx half a pound more than my similarly modded Caffeine 29'er 1.

    Mine came with the same wheelset and spoke combo. I guess switching the spokes to revolutions (as I did) will get you boys in to the 22.5 lb range also.



    PS: These are awesome bikes. My ~$6,000 CDN Rush spends a lot of time hanging up in my basement since my 29'er arrived.

    I've thought about it and i cannot see what could possible be problematic with these things. Maybe Cannondale uses the threaded press in adapter because they designed it... I think we should hear from someone who has used them and see their impressions. What do you see as potential problem with the plastic reducers?

    nothing wrong with the plastic jobbies! the removal / fitting of the press in adapter is a costly hassle.

    I plan on switching to Revo's. Do you have the spoke lengths handy?
