im just wondering on how to justify the maximum fork for a frame ???? (hardtail) is there any way of measuring ? is it to do with the chainstay being 100% level ?

    I saw somewhere else that you have a Landrover Tahora. I believe it has an 80mm fork. I dare say you could get away with 100mm, but I wouldn't push it any further than that.

    However, having seen the standard of your posts elsewhere, I imagine a 130mm+ fork will be finding its way onto your frame very soon...

    it has nothing to do with chainstays.

    give us the make and model and will give some ideas.

  • yeah your right but the forks i have are 100mm i just want to get sum new ones for my next frame but would probably put them on the tahora to kill it hahahaha i cant remember what forks i had on it i took them off the same day i got the bike

  • ive got a landrover tahora at the miniute but getting the NS surge or the azonic steelhead pro not sure yet , im one of them people who bend the rules of geometry im thinkin if i get the surge ill get pikes? or if i get the azonic ill go for totems ?

    totems and oikes are very, very different forks, totems are huge freeride forks, pikes, aggresive Am forks. i had a tahora once, id put no more than 120 on there, you wont "bend the rules of geo" youl just bend yourself, dont bother, buy a new frame for the new forks, and sell, the landie, of maybe keep it for a town hack.

  • haha yeah i would probably end up dead , well the surge says itll take upto 160mm forks max , so would 20mm+ on the totems make a difference? im gonna melt the landie down and make a seatpost out of it :D oh yeah the azonic steelhead pro ive read that someone has 200mm forks on that !!!!!!!

  • pikes are baby freeride forks for freeride hardtails and short travel FS bikes, they're more than tough enough. The rev is the am fork which is a fair chunk lighter.
  • just looked at the Rock Shox Revelation Team Dual Air Forks 2010 mmmmmmmmmmm there nice i should of said im looking for one with a maxel as i keep snappin qr's :oops:

    yes, 20mm more will make a dif, itll ruin your warrenty, ruin the sorted handling, probably snap the bike, and if they say 160 MAX they mean 160 MAX they have tested it and 160 is the most travel it will accept before it becomes dangerouse.

    People talk about geometry as if you can't mess with it, but look at Cotic, the Soul runs like a race bike at 100mm, like a tough XC bike at 120mm, and like a perfect trail bike at 140mm. Then with the exact same geometry on the BFe, fire in a set of 160mm Lyrics or somesuch and go and do the megavalanche. Not all bikes suffer.

    Not that this matters if you snap the head tube clean off or fold the main frame in half by fitting a fork too long for the frame to physically deal with. Someone told me a line once, which I like- if you add a lot of extra travel to a bike, if you actually needed the travel you'll break it, if it doesn't break you never needed the extra fork :wink: It's not quite true like, i put longer forks in mine not because I wanted 140mm of impact soaking, I just wanted to slack the bike off, but it's still generally quite accurate. If you're riding the bike hard you can't take liberties with it.

    Adding longer forks has other effects too - slacker head and seat angles (and with the latter sat further behind the bottom bracket), higher bottom bracket, longer front centre, longer wheelbase.

    Some bikes do go a bit wrong :lol: The opposite of what I was saying can apply, like, I had an On One Scandal. Nice bike, warrantied for up to 130mm of fork but when I put my 130mms in it, it rode a bit like it was pissed. Went downhill very well but it felt long and floppy and the seatpost was so slacked off I felt like i was sat behind the wheel. (On One fans get a bit upset sometimes when I say that, the other side was that at 100mm, it was fantastic- incredibly light, cheap and comfy)

    But then my Idrive actually rides better with 140mm in it than it does with the 130mm it was designed for. And so did my Kraken, with 130mm instead of 120mm. Funny old world.

    The Azonic Steelhead Pro is a DJ frame and designed for 100mm forks.
    The guy that put 200mm, probably put it just for that picture.

    Also if you want to put Totems, cheap alternative is the DMR Exalt, which can take
    150-170mm forks so 10mm more shouldn't be a problem for a 3.1kg, 4130 frame.

    And how the f*** a local guy runs his 150mm Drop Dff qr forks on his low end
    Trek 3900 2007, which originaly came with 70mm forks. That's insane. :shock:
  • just for the record... I find the NS Surge handles and rides way better at 160mm.

    Adjust the Uturn on my domains every now and then to try it out but you just get chucked over the front end, even with 140mm.
    I also find it easier to climb with 160mm!

    Its worth noting that (IMO) the Surge is a proper play bike... its heavy, strong and built to go downwards....

    Not one at all... bloody brilliant bike, built like a bloody tank!

    BUT, I am now building a more trail friendly HT so I can ride a wider variety of trails :)
  • love it :D im jus not sure on color though :(
