1a2bcio8 Posted November 10, 2011 Report Share Posted November 10, 2011 I've just bought a new stock bike and it came with some metal backed magura pads in yellow. At first the brake had almost zero hold so I cleaned the rim with muck-off and sanded the pads down until they were 'fresh' looking. Now there's a small amount of hold but hardly any at all. Too dangerous to ride with. Can anybody suggest a resolution to my problem? The seller stated that the pads were Tnn but I couldn't find that yellow tnn pads existed? The rim has a light grind at present. Any help would be appreciated as I'm desperate to get out for a ride on my new bike. Quote Link to comment Share on other sites More sharing options...
Laurence--Trials Posted November 10, 2011 Report Share Posted November 10, 2011 (edited) Yellow pads did exist, they were made a while ago, one of TNN's first pads if im not mistaken, they were made for smooth rims. If you go on TNN's site/youtube channel you may be able to find more about them. My friend alex had some a while ago i cant really remember what they were like though, sorry, however he found they were shit, i went on his bike to test them gave his bike back and they were good, maybe you need me to ride your bike EDIT: whats your new bike?

Mark W Posted November 10, 2011 Report Share Posted November 10, 2011 You may be thinking of CRMs there - they're amazing pads though, so I doubt you'd have many issues with them. If you could put some photos of the pads or backings up that might help Ben. Other than that, get a grind on the go if you can! Even more useful for when it's properly winter.

It's a Simtra st-1 or something like that. Seems a bit too long and low for my tastes but I'm going to get a higher rise stem and see what that does. May have to look into a new frame though to be honest. Maybe they need bedding in? I mean perhaps you bedded them in for your friend? I think they are basically new. Is that the case with magura pads? I'm not very well versed with trials tech these days... Thanks though. Quote Link to comment Share on other sites More sharing options...
Mark W Posted November 10, 2011 Report Share Posted November 10, 2011 If they're not perfectly square with the rim they might have to wear until they are, but that's the only real bedding in you're likely to need to do. It's more noticeable with metal backed pads because the actual pad is stiffer so won't flex to shape as much as a plastic pad would. If they're not square they'll generally suck.

1a2bcio8 Posted November 10, 2011 Author Report Share Posted November 10, 2011 Ok, Cheers Mark. I think the pad is pretty square with the rim so I'd out rule that as a cause. Here's a pic anyhow: Quote Link to comment Share on other sites More sharing options...

I think the pad is pretty square with the rim so I'd out rule that as a cause. Here's a pic anyhow: That picture is saying heatsink yellows to me, Heatsink backings defiantly/100% so i would have said the material is heatsink too! EDIT: In the slim chance that they are TNN check this: skip to 0:40. Edited November 10, 2011 by Laurence--Trials Quote Link to comment Share on other sites More sharing options...
Little Yoshi Posted November 10, 2011 Report Share Posted November 10, 2011 might just need a new grind. Mine seems to lose abit of hold if the grind is down. Still stops you but wouldnt trust it to much. Quote Link to comment Share on other sites More sharing options...
1a2bcio8 Posted November 10, 2011 Author Report Share Posted November 10, 2011 Yeah this barely holds. It rolled out on me in the street just doing a small gap off the pavement. Thanks for the advice though, chaps. And Laurence, I've bought a tgs bike just to mix it up a little. Sometimes it gets boring just riding 24" particularly when you're sometimes on rides where you're the only one on that sort of bike. Quote Link to comment Share on other sites More sharing options...
Laurence--Trials Posted November 10, 2011 Report Share Posted November 10, 2011 (edited) Okay im just gunna hijack your thread a little here, anyone know how long it would take a magura pad (heatsink blue CNC) to bed in (riding time) on a smooth, unground, anodized rim? Average.. i know its hard to say... Just want to know how long i should be looking at, minuites, hours, days, weeks? Sounds good ben, any plans for a video? (assuming you get the pads working?)

I'm not really getting anywhere with filming anything at the moment. I the tore the ligaments in my ankle recently and started uni so I haven't even been riding a great deal. Maybe at some point though when things are a bit more settled. Quote Link to comment Share on other sites More sharing options...

Ali C Posted November 10, 2011 Report Share Posted November 10, 2011 I wouldn't really say those pads have much hold at the best of times (heatsink yellows). If you are after hold I would deffo recommend some TNN LGM pads. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted November 10, 2011 Report Share Posted November 10, 2011 I found that my old Heatsinks varied massively from each refill. One would be good, the other not so good. Not what Id call consistant. Now running LGMs on the same rim. Properly good brake. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted November 11, 2011 Report Share Posted November 11, 2011 Purely to add some balance to the current trend, I've been running a set of LGMs for the past 9 months or so and they've been pretty shit. In ll the time I've had them on I've had about 10 minutes of reliable, consistent braking, with the rest being decidedly sub-par. No idea if there was a 'bad batch' or anything like that, but might be worth bearing in mind. Most people seem to get on really well with them though Quote Link to comment Share on other sites More sharing options...

Mikee Posted November 11, 2011 Report Share Posted November 11, 2011 How stiff is the frame? A booster might improve things, It usually works for me anyway. It's funny how pads work differently for different people. Heatsink yellows is my current favourite and has been for ages now. I haven't tried TNN pads though because I haven't felt the need to change. Why risk possible disappointment when I am happy with what I have.

forteh Posted November 11, 2011 Report Share Posted November 11, 2011 My HSB yellows have been unreal for coming up to 2 years now (I don't get to ride as much as I like now but they've lasted really well), only ever slipped through when the grind is properly dead. I know people have used them on smooth with good results but I think that's on plain anodised aluminium not dull grind. Put a light sharp grind on there and they should work well. I also found that having the brake setup too stiff stopped them working as well, makes no sense but with a 4bolt control booster my brake slipped through, switched to a lightweight 2bolt and its loads better bite and hold but unfortunately much noisier. That might just be a function of my ti frame and brake setup though, with so many things in trials what works for one doesn't for another Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted November 11, 2011 Report Share Posted November 11, 2011 If they are that bad why are you still using them after 9 months? A combination of a severe lack of funds and the fact that I don't rely on my brake where I can avoid it? I prefer to land on top of a wall rather than halfway up the face and fade to black. Bonus is it's been practically silent 1 Quote Link to comment Share on other sites More sharing options...

Greetings Posted November 11, 2011 Report Share Posted November 11, 2011 I wouldn't really say those pads have much hold at the best of times (heatsink yellows). If you are after hold I would deffo recommend some TNN LGM pads. My experience exactly. Had Yellows on my bike and the front pads just stopped working after a few rides (sounds like the same problem Ben is having) and the rear ones were never any good. I spent quite a lot of time fiddling with grinds, brake setup etc. to make them work but to no avail. On the other hand I managed to set up LGMs in such a way that they lock the wheel with no effort at all. Quote Link to comment Share on other sites More sharing options...
