Anyone know anything about disc brakes?

someone linked some epic disc brake service kit (with rotor truing tools), thought I had bookmarked it but clearly not and I now need to buy it as my front is super wobbly. perhaps it was @edscoble ?

suggestions for good 140mm rotors also appreciated - would recommend heavier people to avoid the 140mm ashima weight weenie rotors

FWIW I've had no problems with 140 Ashimas, I'm 12 stone so somewhere in the middle. Reckon I'm going to try Hopes when these wear out, if only for a comparison.

Hopes

I just bought some spendy Hope rotors.

They are kinda disappointing - trail bike feels a bit underbraked now, compared to when I had the equivalent Shimano Icetechs.

They might improve in time. Or maybe the Icetechs are just that good. Might be the later, and that Icetechs are soft; I killed them after a couple of years.

Don't know! I don't have any rattle, but the left hood is ridiculously baggy now. I emailed Mantel (got them from there on Black Friday last year) and they've asked for pics, so I'll see what they/Shimano have to say. I have just ordered another set of hoods, but I guess there's no way to know whether they're an old batch or new?

im only 13.5 stone but the front has warped something chronic. and they absolutely eat through pads

think I will go for some centerlines http://www.chainreactioncycles.com/sram-centerline-1-piece-rotor/rp-prod120149

@swedeee known issue yeah I ended up buying hoods myself as Madison wanted me to go to an Evans to get them warrantied (wouldn't just post me the hoods) as the shop I got it from shut down. No fucking way am I trusting Evans with my safety.

with rotor truing tools

thumbs are fine for that with rotor still on bike. Use gloves or clean with isopropyl alcohol afterwards

I'm using the centreline and they've been fantastic.
No warping and no braking issues.
I'm only 11 stone though so not sure what the small weight different would make if any.

Yeah, was debating those too, seem pricy for a one piece design though. I suppose the 2 piece ones are 45 so somewhat reasonable.

will give it a go later

have only heard good things about them. way less "gappy" than the ashima ones which is what I want

are 2 piece rotors that much better? I have ice tech ones on my 29er but its hard to compare

I heard one of the funniest things ever at the weekend. An 'old' friend was saying that disc brakes are shit. I asked him why, he didn't really have an answer, then I asked if he'd ever ridden a bike with them on, and he evaded with "They're shit because they pull to one side when you're braking heavily"

#oldmanmyths

christ haha

Yeah I went from a 'gappy' rotor. The main reason being I could hear the pads catching the edge of the gaps and could even feel the shudder as it went over them. The centreline are so smooth when braking. It's lovely. (As lovely as braking can get I suppose...)

exactly what I want, having the exact same issue. will get a pair in the coming months

Probably not much difference in the real world but I haven't tried to compare.

Funnily enough, he's not wrong, but not as dramatic as he make it out to be.

It's not noticeable, and isn't an issue though. Unless your bike is setup wrong. I think the larger problem for him is fear of change.

I think the larger problem for him is stopping

Do you not feel the slightest of twist when riding with a straight steer fork?

Modern fork almost eliminate this, but I had notice that slight flex, but it was way too small to really impact the handling.

Yeah. That could be applied to most of his posts. Wait until he goes off on tyre pressurezzzzzz........
