    Is the ISCG 05 standard being used accross the industry yet? I don't see guides specified as to which they're meant for, so I'm not entirely sure.
    DW, maybe you can shed some light on this one?

    For 2006 the following companies will use ISCG05 tabs

    Trek
    Iron Horse (has been using them since 2005)
    Devinci
    Intense (gradual change over)
    Cannondale (new DH bike)
    Haro
    DMR

    More to come....

    I read that the new '06 version of the Ventana/Go-Ride El Ceurvo was going to use them, too.

    My million dollar question.........

    Is ISCG 05 chain guides and such work with previous bikes with ISCG tabs? Or is it something all on it's own?

    I'm just curious, if my bike has current ISCG tabs, will something that is "speced for ISCG 2005" work on it?

    Better yet, will there be an adaptor?

    And does it come with fries?

    You would have to run an adapter to fit ISCG05 on an older frame mount, as the new mounting circle is a larger diameter. 74mm, I believe?
    e13 would be silly not to make one...

    That would be awesome. I was hoping they would change over.
    Chain of events -
    I spoke to Chris Van Dine, Ventana's top gravity rider, about this traveling back and forth to the MSA World Cup. I told him about the benefits of using the real standard.
    I then spoke to Ventana about this at Interbike with Chris Van Dine.
    Sherwood sees the need for a true standard and values his pro athletes feedback.

    That would be awesome if Sherwood uses it. As a high end frame manufacturer it will make sense for him to make the transition.

    thanks for the heads up. I will check into this as well.

    There is going to be an ISCG 05 to B.B. adapter. I don't know if there is going to be a an ISCG 05 to old ISCG adapter.

    I disagree.

    Actually, the issue of the old ISCG pattern is that is just that, it is not a standard. The pattern does not call for a clear clocking from the rear axle. ISCG05 standard does.

    What does this mean? Several frame manufacturers have produced frames with several varying OLD ISCG pattern clockings, whether it be 30 degrees clock wise to 20 degrees farther counterclockwise... etc.
    Why? because the prints at iscg.com are not clear enough.

    So it will be impossible to make an adapter plate for OLD ISCG pattern to fit to an ISCG05 standard back plate.

    One of the main reasons for ISCG05 was to create a true standard. this true standard was developed by several frame and component companies including NORCO, Cannondale, Truvativ, MRP, RaceFace, e.thirteen....
    The standard will also allow for proper set up by frame builders... meaning no guess work!
    The ISCG05 standard will work with BMX, Euro, stnadard and ISIS Overdrive BB shells.

    go to www.iscg05.com. All of this info can be found here.

    I prefer ISCG'05 (which I have on my sunday) primarily because it allows more clearance for external bearing bb's.
    I had to do a bit of dremeling to get the iscg guide to fit over the bearing cup's on my enduro.

    sooo.... just out of curiousity are all the frames previously listed actually running ICGS05 tabs.
    and any additions / deletions to that list.

    BTW the ICGS05 website ist kaput
    as well as the onepointfive.

    07 Norco runs both. Pretty simple, the plate just has two sets of holes offset slightly to make room. Now we are talking! Its how it always should have been.

    I'm yet to see a US BMX bb with ISCG05 tabs...

    So what's the advantage of any ISCG at all? Why not just do BB mount chainguides? Frames and chainguides won't break when the lower roller hits the ground or a rock, the guide will usually just rotate, at least in my experience. Heck, my Gamut fit just fine on my external bearing Howitized BB, and several times it hit the ground and rotated.

    The only one I see is tighter chainline. I have to run a couple spacers to kick the crank out far enough to clear the guide w/ the BB adapter setup(Cove/E13/Saint). This means fewer threads supporting the BB cup, not a good thing, but it hasn't caused me any problems yet.

    Running the ISCG tabs mean the cranks can usually be run with no spacers, providing the most "inboard' chainline possible...I think

    An e.thirteen guide will set up with the same chainline for either ISCG or ISCG05, an industry leading chainline narrowness of 49.5 with a flush to BB mount ISCG/05 mount I might add.

    So I'd need BB spacers to get the crank to clear the guide even bolting the boomerang directly to the tabs?

    It doesn't really matter since there are no tabs on the Shocker anyway and my last frame had them clocked wrong (M1)

    One major advantage is that you don't need to remove cranks and BB to make positioning adjustments. Such as when you hit it and it rotates like you mention....

    Well if you'd hit it more often it would rotate easier...

    I always could twist my bb mount guide back into place by just tuggin on it. My ISCG guides require pounding on the roller with a rock to get it out of the chainstay (but it requires something pretty stupid to get it there in the first place).

    Hey buddy, I never claimed I know all the models, just naming a few. :)

    Other frames that use the performance standard -
    Knolly (i think all of them do?)
    Santa Cruz (V10, VP Free, Bullit)
    Versus (select models)
    Commencal (will on new 08 models)
    Lapierre (will on new 08 models)
    Intense (new DH frame will)

    Please note that this is not a complete list.

    Dont be so hard on yourself :)

    Hey, what can you do, I mean, we ride our bikes in a rock, log, and other immovable obstacle strewn environment. At some point you are going to smash your guide into something, and by Murphy's Law, usually during your race run... :)

    To answer the poster's question, I belive that ISCG05 is found on more bikes than ISCG at this point. It certainly is stronger and lighter.

    It's only happened a few times, and when I don't have allen keys. By "something stupid" I mean like trying to ride over a picnic bench while drunk (its really, really hard.. wear your helmet kids).

    It's actually surprising how durable those LG-1's are considering how little there is of them.

    Why did the bolt pattern spacing have to change with the conversion between ISCG and ISCG05? Why wasnt the regular ISCG standard updated and edited to accomidate for the proper clocking in regards to the rear axle/whatever is used..That way instead of having to make all new chainguides, and BB shells, everything would work.

    It just seems sort of assinine to me to make use of a larger bolt pattern to adapt to a completley defunct and obsolete bb standard(s)...(american isnt coming back...ever) or basically defunct ISIS overdrive standard. I guess once everything is converted its not going to matter as much (besides having to weld tabs on some frames rather then machining a one peice bb).

    The bolt pattern needed to get wider to make room for external bb's. I had to dremel the crap out of the guide on my non-iscg'05 guide to get it to clear the bb bearings.

    ISCG05 Standard vs. ISCG old pattern.
    Advantages of ISCG05
    1) it is standard and it is a living document
    2) the standard accounts for the rear axle so tab orientation is set. It is not an approximate 'let me put the tab riiiiiight here today' orientation
    3) tab BCD transmits half the impact as the old pattern. this means the tabs are twice as strong = fewer failed tabs = fewer stripped threads = more time on bike
    4) stronger back plate b/c spacer between center hole and counter sunk slots is greater
    5) tab mount distance from BB is set - allow for easier installation
    6) wider stance = wider platform for the back plate = lighter backplate
    plus
    other reasons .....
