Please.... do me a favor an read before you write.

Not blaming Tarty really nor the seller I bought the frame from. I will ring him tomorrow to see what he has to suggest. I was talking about the 640 vs. the 820 caliper.

Right but the 820 saint has exactly the same caliper.

Re-read my entry post. There's not a single question, just ranting. I had a Saint (or rather a Zee with a 810 Saint lever) and it broke after a months use. I do ride but if you've had a Saint on the rear a HS33, even with a Racing Line lever, is just not enough especially when riding in muddy and wet conditions as I have done a lot these past days. That's why I bought a Trialzone because I think it won't crack like the Saint and has the same power. It just doesn't fit and if I send in my frame, there's no riding whatsoever.

Have you actually tried grinding down a steel rotor by 2mm? I did and it's near to impossible to do it right because the heat produced warps the rotor that much, that you can't use it anymore. edit: I'm not actually sure that 2mm would be enough as the axle is in its lowest position and raises the rotor when tightening the chain.

I'm quite aware about my two options as I wrote above. The thing is that recently I have a lot to moan about because things just don't fit or work! Frames that don't work with the advertised gear ratio, stems that can't clamp a bar tight enough to prevent bar slipping, stems that are not welded straight so that the bar is 2cm higher on one side.... Echo TR freewheels that brake after 1 month of use. It appears to me that I'm attracting crap products even though I don't buy the cheapest stuff out there and read before I buy actually. I am sick of warranty issues because they keep me from riding. Only this month I had to return 3 products under warranty and got new ones but every time have to wait. That's basically what I'm actually on about. I want to ride and not wait for companies to revise their crap products!

There's no such thing.

1. Makeshift solution because my frame seems to be a B stock item. And you don't know how many times I've heard the sentence "Just get..." since I've started with trials. I do have some money but I don't always want to spend it twice just because the things are poor quality* or how Tarty states: "awkward installations" 2. That's why I bought a disc frame. *I'm aware that I'm about the only one complaining about trials specific parts but I don't give a f**k.

and run a 200mm disc on the rear? I have two options. Either I return the frame for it doesn't state anywhere that it can't be used with an IS Caliper or I'll get the 175mm rotor from Tarty. Funny thing is that there are 3 people. I know of that had to put shims in between the adaptor and the PM caliper to get it to work. All of them have gotten their frame pretty much when it first came out. The one person who got it after waiting for Tarty to restock doesn't have this problem.

Do you know what a IS mount caliper is? If not, here's a picture of mine:

BECAUSE I RUN AN IS MOUNT CALIPER! Sorry.

Got in contact with another guy in Germany who has this frame. He just told me that he had to put spacers in between his PM brake and adaptor as well because it wouldn't fit with a 180mm rotor. That is just shite. Again. Have you had the same problem building Dual Disc 24'' Echos? I believe that you have sold them as a complete bike as well, haven't you?

Well the pads have been running for quite a while so they should've bedded in by now. The pads I currently run are loud as f**k but hold isn't really there, same with the Trialtech pads. I don't think it has to do with the angled sidewalls really. As soon as the pads are bedded in, they touch the rim equally or am I mistaken? I'm probably not gonna bother with ADMs right now as I'm gonna put pack the disc on the rear soon. Maybe it's the trialtech rims that are kinda shite. I remember using Trialtech pads on an Echo TR rim and they were very good even when soaked.

Same goes for a Cane Creek 110 and it has a lifetime warranty.

I have to be the gravedigger on this one. I am just wondering. On my 24'' I ran dual Saints and especially on the rear it was an awesome brake (until it broke) so I had to go back to rear HS33 (Racing Line lever to Magura slaves in my case) and I don't really like it. With a light grind on my Trialtech SL rim neither the Trialtech pads (in CNC backings) nor Familybiker's pads (that perform equally in the dry) have as much power than my disc had. When locking the rear with the disc, it was LOCKED. With the rim brake it almost always slips a little and in the wet I can't even rock the bike w/o the brake slipping a little. Now I set up the pads perfectly square to the rim and I believe that the grind is also well made, plus frame flex is almost non existent with the Trialtech booster. Still, the brake doesn't come near a disc brake even in dry conditions. When looking at videos of stock riders, they do seem to have hold in the worst conditions so I'm asking myself what I am doing wrong. Could it be that my technique as a beginner is just shite and therefore the brake can't cope with my 85kg or what is it?

I can't even do a sidehop for the description is lacking.

Both are reliable and great products, I'd go with a Cane Creek 40* though (budget option) or a 110 which is better engineered than a King for a little less money. A king just lives from it's name. Some years ago there weren't any other high class products available but that has changed. Between the two you mentioned I'd go with a Hope, just for the moneys sake. *Put mine on my bike messenger bike 5 years ago and have been riding around 70.000km since then in all conditions so it has seen quite some rain and whatever... Haven't touched it since I put it on my bike and it still runs as smooth as on the first day.

I have to buy a Mono Trials rotor anyways. Might as well buy a 175one.

Well... I'll call the shop on Monday and will see what they say. They may have a 175mm rotor which should do the trick. I thought about going down the warranty route but I want to ride and not wait for a new frame to arrive which then has other problems.

So basically my best bet would be a 175mm rotor? Didn't know something like this existed. Have you come across this problem in your shop when building up Dual Disc Echos? Is there a huge hold/bite difference between a 175mm and a 180mm rotor?

Oh please.... As if Shimano made a 183mm rotor: SLX Disc by niconj, on Flickr I tried that but I would have to grind off at least 2-3mm which is way too much!

It is 180mm. Just like the Hope rotor.

This is the position the disc is in with the axle in its lowest position. I cant even move the wheel then w/o the disc touching the caliper. When tightening the chain it gets worse. It's a Shimano Disc but it's the same with the Hope one. On the front Trialtech Sport Lite forks the same caliper fits perfectly. I've already contacted Echo to see what they think about it. I will also contact the seller I bought the frame from in June. Disc¹ by niconj, on Flickr Disc² by niconj, on Flickr Disc³ by niconj, on Flickr

How do longer bolts change the position of an IS caliper?

There are two options. Getting a new caliper for 100€ or grinding down the rotor. That is some f**ked up shit. I am really angry right now. Should post in the Angry Thread.
