hi guys
i own a 2010 base model r/hopper, and i'm thinking of going down the rigid fork route. the type of riding i do is leisurely tootling along local bridleways and woodland routes, no mad downhills or jumps or anything like that, plus commuting to work every now and again.
after doing a bit of research/measuring, i reckon an axle-crown of 440/445mm is what i need to compensate my 100mm sus travel, but does this take into account the 15/20mm sag which occurs when sat on the bike with sus forks?
so far i'm thinking of- carboncycles exotic carbon/on-one carbon/carboncycles exotic aluminium, all of which seem good value for money, have any of you guys had any experience of the above? is carbon a good option for a rigid fork (strength wise), or should i go with aluminium? strength is my main priority, as whichever i choose, i'll still be lopping over 1kg off the front of the bike, so 30/40grams difference doesnt bother me. i weigh 12 stone, so i think i'll be ok on either option. thanks for reading guys.

    The Rockhopper is designed around a 480mm static suspension fork (ie non sagged). A general rule is to take off the sag, then another 15mm to get a rough idea of a rigid fork length. So I think you are in the right ball park. Go slightly longer for a more stable ride, shorter for quicker handling.

    The Exotic are the same as many other forks, but are the cheapest. Is good kit.
