    Light-bicycle wide rims = Flow EX's??

    this might be far fetched, not sure. tried and true top end alloy rims in the Flow EX, to the new comer with a young but good reputation from afar using a totally different material. part of me wants the best tough rim and peace of mind (the flow) the other part wants the same, but the new fangled weight reduced, still stiff as hell has big appeal. both will be very spendy with the light bicycle even more so. the reputation of LB while not spotless does continue to improve. tough call...

    LB is significantly lighter and significantly stiffer. You take some risk as there have been some issues, but mine have been bombproof so far in very rocky conditions....I would go LB without hesitation when choosing between the two.

    significantly stiffer? wow, quite the endorsement for LB, given the new Flow's stellar reputation.

    Been on the wide LBs for over a year. Thrashed the hell out of them. Lots of rock strikes. They scratch, but are still solid and true.

    The biggest drawback to the Flow Ex is the inside rim dimension. There is an article written by Richard Cunningham on pinkbike that explains what a huge difference the width makes.... I will look it up and try and post it.

    Thanks for sharing! I have always felt "wider is better" for tubeless...now there is evidence for the madness!!!

    WTB Frequency i-23 is another viable option. They are light, stiff, and relatively inexpensive. The inside diameter is 23mm, hence the name.

    So I must be missing something. Last I saw the LBs were 23mm inside and the Flow EX are 25.5mm so the Flows have the advantage on width.

    How wide a rim are you running? Are you confusing the low profile of the bead with the width of the rim?
    Flows are amazing, and lb rims are looking better!

    Mine are currently 23mm, but I am upgrading to a new set of carbon fiber hoops and the I'd is 24.8mm. The exterior is 34mm x 26mm.

    I guess the main issue is how current their web site is regarding their product offerings. I would like some WIDE light carbon rims, and I can't tell if they make them or not. I'd take a little narrower than Flow Ex, if I can save 150gms per rim and run them tubeless?

    The wide LB rims come in around 395/400 grams and can be run tubeless w/ Bonty rim strips.

    Are we talking 29er rims? In what ID width? Because this is something I am interested in. I haven't really gone through those other threads because they are just too long...

    LB rims are 23mm ID, ENVE is 24, I believe Flow EX is 25.5.

    Game changers compared to the Flows - at least the older ones. I've run Flows (I9 Enduro wheels) and the Light Bicycle rims on my RIP. Love the carbon rims (use the Bonty strip and have never burped, airs up easily with a floor pump).

    Ran the Flows on the RIP until the carbons arrived and were built in mid-April 2012.

    Nics

    Here they are a year later and as I said - game changers.

    Old Flows were 22.6mm. Not even in the same zip code as the new Flow EX.

    Isn't one of the benefits of the Stan's bead shape a wider tire profile?

In spite of the inner rim width being a mm or two narrower than the newly designed rim hook of the Flow EX, the stiffness on a full suspension bike is a huge . Not to mention my carbon wheelset with the LB's are 300g lighter than my I9 Flow Enduro wheels.

    Width aside, the performance of the carbon rim is - IMO - justifed over and above the Flow rim at least in terms of the genre of XC and Trail bike (whatever that is for various opinions).

    And that's saying something because the Flow is a great rim.

    I'm not convinced. Okay I am. Did you build the wheels yourself? I think I'm ready to take the next step here...

    My LBS built them. AC hubs and the kit to convert back and forth between regular QR and 15mm TA, Wheelsmith spokes, LB AM rims.

    Bonty rim strips?? I've heard that tape is good enough - is this not true?
