MT that's way too technical
i have an easier question - what frame is that? :)

It's a different compromise from the traditional position, only really viable with steel forks. The correct solution to the wheel ejection issue is a through axle.

but how many wheels have you come across that have ejected?

yes there are a few that have been documented on the net but the main one did not even have tabs on the fork drop outs.

and those tabs have been there since the year dot.

and i have a nagging feeling that the First disc kit had two calipers on the font of the fork legs. But that was when i was still rigid and cantis and did not believe in suspension.

Where can I get an inexpensive, decent quality, straight-bladed, lugged steel, straight fork? In white or chrome.

BLB sell them, I think £60 a pop?

That sounds promising. Cheers Ed.

tokyo fixed too josh

Bonus. Would rather give TF my money to be honest. Will suss it out. Thanks comrades Edscoble and Comrade Zed.

Oh yes, Tokyo stock them as well, forgotten about them, they're actually £50, look like it'll do fine for you;

Don't forget to check the rake on your track bike ginger.

i miss you josh. is there anything I can do to alleviate that?
like a bike tour?

I'm a bit out of action Henry. My shoulder feels ok but I'm fairly certain it'd melt if I sat on a bike.

But definitely up for a bike tour, just not yet.

Pub?

Nice work Ed, that looks like exactly the tip tip clubbing jam I've been after. Cheers.

sure, my cousin will be round soon too, you guys can talk architecture.

Lolz.

yes disc mount on the front of the right leg so that a standard caliper can be used and fitting the mudguards is easy. Also it is where I believe they should have been in the first place ,)

hose routing will be internal to the lever.

See i remember a formula disc brake I saw pretty much just as discs were starting to appear in DH. Think it was the first bike i ever saw with one. It was mounted to the front of a rigid fork and I always assumed they were better off mounted to the back of the leg so that when applied the force pushed them towards the forkleg, rather than pulling away from? is that not a factor?

tonight i replaced all the (frayed) cables on all my bikes, re-indexed the roadie, trued a rear wheel (ish), and cleaned and checked the bike for sale.
because i was bored. and didn't have a 1" headset lying about.
lame.

Henry, please check if you have some spare, otherwise it'll be a pretty annoying night realising you need to pick up the part tomorrow.

what you on about ed?
that's a completely separate bike that the 1" is needed for, my bikes all work brilliant.

That's why they put them on the back of the fork leg. The earliest CB750s had the calliper in front of the fork, but since then it's been one way traffic. The problem is that putting the calliper behind the fork pushes the wheel downwards when you apply the brake, which is fine with through axles but it is trying to push at an open door with conventional dropouts. As nicklouse points out, well documented cases of properly installed wheels being forced out are few and far between, but nobody who understands mathematics would argue that it isn't an accident waiting to happen, and one which can be easily avoided by an existing alternative design which has several corollary benefits and practically no downside for the majority of riders who don't need to repair punctures under race conditions.

liking the langdale

I have a 1" headset.

actually, that's a lie, I have two.

how desperate are you to pick it up in the middle of the night?

never realised there was even an issue - but yeah easily solved by an alteration to drop out design.

Bratavus cant remember the model, but quite a generic Taiwan frame form a few years back, the wheel and nexus hub went on an other bike and i attacked the rest of the bits.

I missed that Formula version the ones i was thinking of was a dual set up with the "mounts" bolted around the fork legs ( to use a road font mech term they were band-ons) I think the fork was an RS.
As to the forces yep there is always the opposite and equal force to consider.
When i was putting it together i did think about the top mount bing ripprd out.

but then there are some nutters out there running alloy bolts holding their IS mount caliper/adaptors onto their DH forks, and when they get too bent they just replace the bolts.

but as this will not be going that fast and the forces will not be that great only 160mm more of an emergency brake for the peds out here. (not to mention my old knees).

and the funny thing the fork that the wheel came out of was on a Tandem.

PS the main reason i did it was that I could, and the forks were the original ones that came with the frame but were also threaded headset fitting, they are now Ahedset fitting.

so what sort of bike is it going to be? singlespeed/fixed? drops / risers? looks like it's gonna be interesting.

its for my cousins bike, he gets here in august, so not really desparate.
4 am ish start tomorrow, and i'm not sleepy...
lame.
