I'm not trying to get up anyones nose by the way, I'm not sure my post has anything to do with Daves posts either except that I think there are some more argumentative peoples on here. Where did Jack (Carthy) break his rockman forks? Also, Mark in your post: You can also consider this point as being a slight nod to something you missed from your post regarding how/why 4-bolt forks almost always break at the 4-bolt mounts, and why they break much faster than disc forks tend to... Are you referring to the weld being a stress riser? Fatigue and 'stress risers' are directly relatable when in an item fails at a 'stress riser' due to fatigue (lolz) but that is what happens, the dislocations start at the riser (weld) If yer not then I am puzzled and would be happy to assimilate your imput on the matter of why forks snap at the mounts. When I say 'not fit for purpose' I mean that if Koxx don't have enough faith in their forks to carry a trials rider through his adventures then I would say they are road forks with maggie mounts and not forks to be used to get over a section of rocks subjecting them to some pretty big forces.. by the way I think all this may be moot as most peoples will probs put their own inserts in where they need to and also having seen these forks for real I would say that in the real world they are extremely fit for purpose. Note: I am aware that the words 'probs, imput and relatable are not real words in terms of the listed approved words in a the english literature but you get my drift?

Thats well cool idea, just one thing, could you not have done it like a wishlist (al la CRC) then the filter would have been easier? That is also cool when you think of how much a road bike/mtb built of the most expensive parts would be!

Really? I think he argues a valid point just doesn't communicate it very well. I think there are some worse on here. Maggie alloy forks snap due to fatigue I will almost guaranty that. Fatigue, as many involved in this vommit will be aware, is dude to cyclic loadings (stress) as fatigue damage is cumulative every time the material is subject to this loading it gets worse until failure. As fatigue is made up of predictable elements and random elements which could explain the different life spans of the same (but different) forks but I would be betting on the use being the determiner. For instance: Jack Carthy is shit hot, I would say that probably is because he rides ALOT (there's that word again) his number of cycles is going to be very high very quickly. He is also pretty big so his actual loading magnitude is going to be pretty high. Fatigue is directly related to the stress range so Jacks Alloy forks are never going to last long whether he bashes them or not NO MATTER WHAT MAKE OR DESIGN I am a shit rider. I don't ride ALOT relatively speaking I am not very big My stress range load will be small because of this I have never snapped a set of forks but I regularly bash f**k out of them. Maggie forks are subjected to higher loading cycles because with discs some of the 'Flex' is taken up by the wheels, they are effectively acting as a cyclic dampener i think, I could be wrong. Moving to these Carbon forks. The simple fact of the matter is, these forks snapped at the steerer tube because that is the weakest link in the system. Having seen a set in real life today, I believe that I would have put in insert down the tube almost, if not all the way, seems foolish not too. I also would have laid the carbon up diagonally as well as perpendicular to the axis, I am not sure if the tube is a stock tube bonded into the fork leg part but it looked that way, I apologise if I got it wrong. also having seen a picture of a failed set, they appear to have snapped below the top bearing which I found very weird, leading me to conclude there was an existent fault in the tube at that point. On the point of the wording on Tarty bikes. I would not refer to the stack height if I were wording it, I would refer to the top and bottom headset bearing faces as it it clearly this dimension that is important and less ambiguous. I would even go as far as to say that as a result of this weird design and need for 135mm 'total stack' these forks are not fit for purpose in these circumstances.

f**kin nice one Slug!

I just view it as unconstructive slagging so its all ok dude

wow you learn something new every day I thought Cap and stan were the same entity, Capt'n Stan, scuse my ignorance.

bummer shame really if they had left a thin web in the slot that would not happen. You buy! 26 dorrah

It's ok no one will laugh. A new Standard unit of measurement is born the AP= 5.9 inches. I can side hop about 4 AP's Why does everyone give Kerr shit when he tries to help people? Change the f**kin record is it, everyone has their own opinion, at least he is willing to say his unlike the many sheeeeeeep on here (not specifically in this topic)

Thats just bent. anyone know where you can get these feckin tyres from?

this made me laugh This made me happy. those cranks are larverly, nice one for posting them up here! I would never have seen them otherwise. I Hope they make them would get them for my Mountain bike.

Awesome nice one fella!

I'll be allright doing em thanks Dave just need weights of oil and volume info. Bring yer moto forks around dude I'll do en for you in the week.

I have to rebuild my bomber z2's and was wondering if anyone has done it and/or if they know what the procedure is? Thanks

I sometimes use gears: shimano 8speed shifter road cassette (6 gears)on a hope trials hub. short cage XT mech. Its handy sometimes.

I've seen Dave do some Mental big AND technical shit on a mod bike. Set out a section for him once that just looked impossible. 3 attempts and he nailed it, with the clock running.

lolz

Ok so I need some tyres for my All mountain bike. 24" I had some Maxxis Swamp things on there but they are just too slow. I currently have a nokian 3.0 Gazlodi on the back and a scwalbe Fat Albert on the front, they roll better (believe it or not) than the swamp things but the grip in the wet on the schwalbe is diabolical. Now I would go for high rollers but they seem to have been discontinued everywhere except the 2.7 which is too big. Any suggestions, need to be good in the wet, good mud shedding ability and not liable to loose it when they hit a wet rock section. Thanks Edit: Klick me what about these?

Ta Da! Klix me

Nice one Slug, not enough 360's,tailwhips and bunnyhops though.

Winner!

That looks like post weld shrinkage to I. there is going to have been alot of heat in the area outlined in red where the weld has been run over a previous weld, which is probably not a good idea anyway depending on the period between the 2 weld. Coupled with the probably relatively strong part I have highlighted in yellow when it shrunk it would have 'peeled away' if you get me when it cooled. my guess is this headtube is cast rather than forged? Even if it was a riding related failure (which we know it isn't) it would be from heavy taps not hooks.

tyre grinds are win as was that vid
