    You ever removed pivot bearings before? You will need a press

    I'm amazed that this thread continues to go on.
    Someone should start making Iron Horse's again.

    How easy we're they to remove? If the bearings slid right out by hand then that means the pivots are ovalized and the frame is ruined beyond repair. As far as I know, no frames pivot bearings, weather it's a xc bike or DH should be able to be removed easily by hand

    24mm socket (it just have to be enough large to slide in the bearing) to the out side, a long screw (M8 or M10) through the bering and the socket and a nut. This will pull out the bearing gently whitout distroying anything. But first you have to remove those bolts.

    Hey, How would you set up a sunday frame for enduro/gravity racing?

    I have spare fox 36 van fork. What shock to use? coil or an air shock? 36 or 34 teeth chain ring? I will use 10speed 11-36 cassette, stock HA, 65 deg.

    or this is a bad idea? (weight, will use lighter parts and wheelset)

    since this is a dw linked frame, will it be comparable to a 6 point, or an ibis mojo HD in terms of climbing efficiency?

    No. The sunday is a downhill bike.
    If you want to be competitive youd be better off on a lighter shorter travel bike, but theres no reason you couldnt have fun on the sunday. Lighter wheels and tires, dropper post, 11-36 cassette, and an air shock is how I would do it.

    Sunday+Totem Air+Air Shock+Hammerschmidt = Win

    But you can do the same on a 7Point and it would look better, and ride better uphill.

    i have this setup on one of my sundays and its really not as much fun as i hoped. For anything with up, my 6 point and my 7 point are a lot more fun. tire selection has a lot to do with it too obviously but the sunday sucks to go up hills on

    thanks for the reply, I will look for a used 6 point or a used giant reign for enduro

    add: sunday is downhill bike, that looks like a trail bike,
    and when the rear shock uprights is covered by the rider's leg it looks like a hardtail.

    that thing is wild! It's either right or a remarkable copy. Has the correct axle and dropout and has lots of sunday-esque features. I wonder what it'll sell for. $275 is a steal, but the fork alone is worth quite a bit more.

    Ha, I don't know about that. If the price is right, I might, but I doubt it'll stay anywhere below $800. Besides, while what I liked best about the sunday was that the overall package was dialed (1.5in headtube, great geometry out of the box, ISCG05, etc), this one has questionable suspension geometry, irreplaceable parts, and keeps the sunday's dreadful shock location. Maybe they revised the shock rate, but unless the whole package goes for less than $500, I'm out. Add to that my experience with the Sunday was severely tarnished by the crappy shock on there, and I don't know if I'd be a good judge.

    -2 degrees cups here.
    5 mm shorter RC4 and Boxxer with max stanchions length so in total 62 degree : ) .
    It is a bit overkill on a flat trial but on steep it will give you some confidence.
    It's your call in the end.

    Rode mine with -1.5*, didn't like it. Would have switched back to 64* for my cat 2 lazy ass. Steering was a bit too lax and not quite "sharp" enough for the speeds I was going. If you're an Udi riding whistler all day long, maybe keep it!

    Please explain! 236mm I2I shocks are non-existant. And offset-bushes won't work very well with the frame. ;) The thing would bottom-out before the shock does. ;)

    I bought a RC4 which came that way 235 or 236mm (the body was cut down) and I was to lazy to sell the shock and just kept it : ) I've heard it's not good to have shorter shock but I can not find any difference in pedaling or anything else.
    Nah it's just on the edge of touching the metal support link on the rear.However the seat is dangerously close to my rear tyre sometimes :P
    off topic - BG change your colour on your Sunday seriosno:P

    Wow, sorry - totally forgot RC4s are able to be cut down - their design makes this possible. Ans as far as i know, 6mm is the maximum you can shorten them. And the problem i was refering to was the support link hitting the seattube - screw the saddle touching the tyre, the frame's much more important! When we did some calculations on an L frame of a friend of mine, it could receive only 2mm of shortening before hitting the seattube. So, there was no sense in doing this. Really curious as to how yours is possible - mind if you share a pic or two of your bike? :)

    Well, when the Sunday was on the market, the builds were with a Boxxer, which i think has an A2C of either 565mm, or a 572mm. And they said the frame has a 65 degrees HA. As far as i know, there are "Factory" frames which have a 66 degree HA. A friend of mine has one and said at first the HA was 66, but now has a custom anglset to slacken it out by around 4 degrees to 62. :)

    Assuming an original head angle of 65, which do you think is the optimal head angle reducer for the best performance, -1.5 or -2?

    Only you can answer this question :P
    Depends on the trials you ride and so on .....
    It's completely personal preference and basically it does not matter what HA you have till you get nice balanced bike.
    When you go slacker than you needed to your bike becomes chopper and it's really hard to turn.
    Hope this helps.
