 Tis all very nice, but how many long travel trail bike frames come with an ISCG mount ?
|
 |
 I'd guess probably quite a few. And probably a good few more next year as well
|

 I read somewhere they were developing a slightly different mount so it can be retro fitted to non- ISCG frames. Edit: Found it ... For those wondering about ISCG tabs on the 575's to mount a Truvatuv Hammerschmidt--I read that Truvavtiv is planning on releasing a Hammerschmidt that won't require ISCG tabs/mounts in about a year. Article said "late '09". Still a ways off, but it's better than nothing I suppose

Where'd you read that Nobby? How could it work without ISCG tabs? Unless they adopt a similar approach to that used by Schlumpf, whereby an extended arm wraps around the chainstay perhaps

Hopefully it works - I just ordered one of the freeride ones from my local shop for as soon as they are available. I want it for my bullit because i like the double chainring but want to run the floating brake arm, which isnt compatible with a front mech, so this will solve that problem for me. Only downside is, the price, its going to cost me nigh on £550.....

It was on mtbr and was posted by one of the shop owners that frequents the forums David. I have to say, generally speaking, he does seem to get these little gems of info from time to time.

 A more likely outcome is that more frame manufacturers will put ISCG mounts on frames that they otherwise wouldn't have done. It's not that hard for them to do, although of course that's no use if you've already got a frame you like. A non-ISCG version sounds a little bit unlikely, but I'll go and ask

don't think so Jimmy, (from watching the install vid) the drive side is more of an older style internal bb with not much of a "clamping" area and the offsets and clearances quite critical.

I agree that it doesn't seem likely Mike but they may see that a huge number of potential customers would be put off by having to buy a new frame too - it's not like it's a cheap piece of kit for starters is it?

 I can't see why they'd bother. Those who would benefit most are not the double and bash-ring users, but those stuck between a triple (or double) or single and chain device. This is a way to run a chain device and still have a wide range of gears. Since ISCG chain guides have been around for years most frames people are likely to use that sort of thing on already have ISCG mounts. Its not really for the long travel trail bike - its designed to allow you to use a freeride bike as a long travel trail bike! Of course the availablity of such systems will cause trail bike to gain ISCG mounts, but thats for the future. As for the new frame - well ironically thats not a huge problem. If you look at the SRP of the Hammerschmidt, and then look at the price of the bikes that are being specced with one you'll see that the OEM's must be getting them at a fraction of the price we'd pay. So if you want a Hammerschmidt it might just be cheaper to sell your current bike and buy a new one specced with it........

 £550?? Triple yowser

Not many suspension designs will cope with that sort of chainline, as most suspension is optimised for middle ring... shame it doesn't gear down from a 36 or 34T.

for that kind of money, wouldn't a Rohloff be a better plan? Though one of these + a Rohloff would be utterly awesome
