Swoofty Posted May 9, 2019 Report Share Posted May 9, 2019 I once swore by Magura brake adapters, but now I've broken 2 in about 2 years. They were both QM5s for 203 rotors. I've ordered the equivalent Hope adapter and maybe they're stronger. The added bummer is that I didn't catch it right away and I'd been wondering what was up with my rear brake (Oh so not a good feeling!). I guess I should be glad that even broken it held together well enough not to fail catastrophically. Braking chains has caused me far more grief. So the moral to the story is when you hear one of those 'PING!' sounds and it's not a spoke or the chain, do a serious bolt check! 2 Quote Link to comment Share on other sites More sharing options...
aliao Posted May 9, 2019 Report Share Posted May 9, 2019 Would be cool if someone made these out of steel, but frames really need to start just doing post mount considering you can’t really get ISO calipers anymore Quote Link to comment Share on other sites More sharing options...
Matt24. Posted May 9, 2019 Report Share Posted May 9, 2019 I recently snapped a Caliper mount after a Shimano mount bent outwards in the middle. I have got some chunkier ones on now which seem fine. Think they are old Hayes ones. Good luck with the hope Quote Link to comment Share on other sites More sharing options...
Mark W Posted May 9, 2019 Report Share Posted May 9, 2019 The Hope ones do seem to be a bit stronger than the cast/forged ones, so hopefully you'll have more luck with them Quote Link to comment Share on other sites More sharing options...
MaderaMark Posted August 14, 2021 Report Share Posted August 14, 2021 Hi! new member here seeking for better answers. my 4th and short lived adapter (Hope), can't think of which is really bad, me, the bike, or the parts... Quote Link to comment Share on other sites More sharing options...
Swoofty Posted August 14, 2021 Author Report Share Posted August 14, 2021 DAMN! Ok that's serious power. Are those 203 rotors or 220? It is better than breaking your frame mount. I very much appreciate it when trials companies put their brake mounts at the 180 rotor position so even if you do go for 203s, the adapter isn't too large. You should probably find a machine shop and have one made of steel. Quote Link to comment Share on other sites More sharing options...
MaderaMark Posted August 14, 2021 Report Share Posted August 14, 2021 still on 203 rotors, I am so curious why this happened, or is it only me? Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted August 14, 2021 Report Share Posted August 14, 2021 Materials fault with the Hope one, very rare (never seen it before). Quote Link to comment Share on other sites More sharing options...
LEON Posted August 14, 2021 Report Share Posted August 14, 2021 Just replace them 2 or 3 times a year, it's a £10 part. You shouldn't expect it to last forever under the stress of trials. Same as a chain. Don't just wait for it to break. Quote Link to comment Share on other sites More sharing options...

The others, except the shimano lasted almost more than 8 months. And it is very hard to find those fat Avid adapters or the formula specially here in middle asia.

Swoofty Posted August 15, 2021 Author Report Share Posted August 15, 2021 I hate to ask, but this is the current world we live in; are you sure those are legit Hope and Magura adapters? The Hope should have a letter cast into the adapter (that one looks like an 'H' version) and the Maguras have white printing with the adapter code (QM5, QM10, etc). That does seem like a curiously high rate of failure. Another option would be to drop down to 180s and use 4 piston brakes (or stick with 2 piston). James Barton uses 180s on his 26" so should work for mortals like us too. Quote Link to comment Share on other sites More sharing options...

I have to say though I’ve not had the set up long so can’t comment on durability but I can confirm that 180 is plenty. Quote Link to comment Share on other sites More sharing options...

All I know is the cost is way more and it felt so light compared to undranded adapters I had. Going 180 will be my next step, if i ever broke another adapter. I am waiting for the one I ordered and try. This is by far the only fat I saw online... Edited August 15, 2021 by MaderaMark Quote Link to comment Share on other sites More sharing options...
Swoofty Posted August 15, 2021 Author Report Share Posted August 15, 2021 Yup, that looks like a real Hope, but like Adam said, that looks like it had a manufacturing problem. Good aluminum doesn't look like that when it fails. Quote Link to comment Share on other sites More sharing options...

Good aluminum doesn't look like that when it fails. i also found soe adapters made from a 7075 heat treated, forged alloy and CNC finished. Not sure how true, but all I can see is the adapter is fat compared to shimano or sram. Thus also looking to Baradine or Bengal, or whichever looks tough if ever that formula isn't available.
