Double Disk/v-brake

[N Roach]

Hi,

Could anyone with experience of using a rear disk on 26" recommend me some sizes and models?

Likewise With the v-brake?

Which type of brake would you faither and why?

any help will do

Thanks

Nathan

Is this mainly for comp type riding and natural Nath?

A balanced variety of both street and natural. i do plan to enter as many comps as possible...

I think that the v-brake might be a good all round brake...maybe im wrong.

What you think Dave?

Edit: Looking for the brake that needs less maintaince.

Also ive seen a few onzony riders with double disk...maybe it could work well...

Currently running a 07 mono trials with 220mm rotor on the back of mine as I allways have had problems with brakes locking. I feel it's much better than a maggy, more hold and generally better control of the braking.

[craigjames]

been running dual disc on my stock for the last 3-4 months and i love it. great power and modulation. the best feeling brake ive ever had, have an avid ultimate im in the process of trying out but i think im going to go back to dual BB7's. i run 185's front and rear but have a 203mm rotor im goin to try on the rear.

[Ubuntu_user]

I've been wondering about this myself... does anyone very often bash their rear disk?

[Greetings]

From my experience:

If you're running a stock, use a hydro brake.

Get the biggest disc you can fit onto your bike, 220 will be good.

why do you need a hydro? my bb7 has been was superior that any magura ive used and a 8" rotor should be more than enough.

reagarding hitting the rotors, ive hit the front twice in time ive used dual disc, never the rear, and never enough to cause it to bend at all.

Ive never used a rear disc on my trials bike but on my street bike it feels nice.

I find though that if you dont have a really solid wheelbuild then the spokes tend to flex and you feel a little lessfeed back from the brake with a disc.

I thought that i would hit my rotor all the time but i have yet to do it and when i ride street i love to do rolling sidehops and stuff so.

As for the model, the only brakes i would consider for a rear disc are the hope mono trials, formula the one or avid code 7.

Used a BB7 and a BB5 on my bike, the power was ok but only with the speed dial thingy on the maximum setting. That made the brake really spongy.

Once flew over the bars during take off on a gap to front wheel because the brake didn't unlock. It's something one can get used to but I can't ride with a brake which will only unlock if you completely let go of the lever. The Hope isn't exactly solid, but it's better.

Have you gone back to a rear disc then Inur? How are you finding it?

Nope, not yet Haven't got any disposable income at the moment. Maybe in a few months...

[basher]

Like said if you going to go disk go bigger like 203rotar.But dont get one and get a vee instead.

I run this set up and its fooking amazing its so stiff hardly any sponge.

08 sd7 lever - new chainreaction 15 for a pair

08 xt arms (not ones with parallel push) - 20ish new but cheaper on ebay

coust pads - 24 new but you could get other pads that are cheap but good.

xtr carbon booster - around 20/30 2nd hand

oddessy cable - new 6 quid

heatsink adaptors - 15/20 second hand

Its best vee ive had, you could proberly get a setup like that for 60 quid with some new and some 2nd hand parts.

Ill never go back to maggie unless its because my vees broke, ill always use vee it holds on the edge of walls so stupidly well.

[craigjames]

i bet you use a grind?

i really dont understnad the backwards idea that you should take an angle grinder to you rim to make your brake actually work. seems really wrong to me!... dont get me started on tar.....

is this aimed at me? well yeah i use a grind. Dont like smooth rims and tar. Ive found with a smooth rim you dont get the same hold as with a grind unless you put tar on and then it just becomes a hassle and feels horrid as you can feel the slight sticking of the pad and still doesnt hold the same as a grind will. Also the bite you get isnt the same and i dont like it.

It seems common sense to me why you would do. FIrst off you createing a rougher surface createing more friction. 2nd your createing more surface area on the rim meaning the pad grips to more of the rim. Also you can ride in the rain.

Vees are VERY good, Only reason I went back to maggie is that the brake set-up was off a bit, and not touching the rim right, could have been solved with a thinner rim. I do like the feel of them though. If I don't get on with maggie, I'll go back, and get a thinner rim, and get a booster too.

[craigjames]

thats my point i dont understand why i should have to do it, surely if it was a good brake with good pads that worked for the intended purpose then you wouldnt have to resort to doing other things to your wheel to make it work properly.....

it wasnt a personal dig, if anything its a dig at manufacturers that make products for this market, that cant produce a brake thats good enough in the first place; that you dont have to take an angle grinder or a block of roofing tar to your wheel to make it work well enough.

my rear disc is way better than my old setup of a maggy, witha light sharp grind using heatsink blues/snowies. im hoping my v set up will rival it with these uber soft rimjam pads on a smooth rim; but i still dont think im going to get the all round performance that im getting from my disc.

But theres nothing they can do to make pads that will work well on a smooth rim in rain is there. Manufactures do make pads for smooth rims but to get them to work at a amazing preformance with no tar would mean making them soft. Then that gives the problem of your lever feeling horrible and mushy. Its a no win situation, if you want a pad to work for comps in all weathers you have to grind your rim, if you want to ride in the rain you have to grind your rim. The only thing that manufactures could do would to have a rim that was such a hard metal that a grind pattern could be cnc'ed on but would take a very long time to wear. But the costs would be stupid.

Or just get a disc.

[basher]

Or just get a disc, and cry yourself to sleep at night becuase you cant believe how stupid you was in getting one.

:bow:

For me, the plus points of a rear disc outway the plus points for a rim brake.

I have lots of hold, lots of bite and lots of modulation, and all I have to sacrifice is a bit of stiffness, which you get used too after a while.

My brother has a maggy on the back of his bike, it's fairly horrid.

But if you left the likes of a good set up vee such as bigmans old one mine or alis then you would be converted.

As you have a super light lever feel helping with arm pump, shite loads of hold, bite, modulation, stiff lever feel, and dont have that horrid locking feel from the disk locking followed by wheel flex

Dont think we'll end up agreeing.

We do agree on one thing, maguras are shite.

Arm pump anyone?

[Matt Burrows]

I'd really love to compare all these rear disc set-ups to my magura. At the moment it is working great, its has brilliant bite and then holds well and feels very solid. It really helps for drop gaps to rails or points etc, and gives you extra confidence for other moves. Its the best brake I've ever tried, and I'm not sure if anybody would ever need more power.

Its only downfall is the AWFUL noise it makes! It can actually hurt your ears and makes you feel like an anti-social goon when riding street. For this reason I can see why a disc is appealing to others, I would quite like to try it myself. But for stock riders there are still very few frames out there that are disc compatible. And with the extra cost and flex it has never seemed very worthwhile to me

We do agree on one thing, maguras are shite.

Arm pump anyone?

Do you really find that a problem? In about 4 years of using rear Mag I've only got arm pump once, and that was in a comp when my front brake failed and I had to rely entirely on my rear brake (not easy!). Have you ever tried indoor climbing or bouldering? The arm and finger strength you need is way higher, its makes riding feel easy on the arms when compared. Maybe you just need to build some strength up rather than blaming the brake?

I've tried Ali's V brake 2 or 3 times over the past year or so, and I always thought it had no bite
