the hs 11 might be a 2 bolt if I remember right, and will not work without adapters. hs 33 whatever should be fine for your muni. it’s the newer and better version. big difference is that the hs 33 has a drag brake feature.
I wasn’t aware magura sold a plain HS33 (no mount), but if they do get that, failing that you want the HS33 EVOII brake. Even though the EVOII mount is useless to you because you will be using 4-bolt (you just don’t use the EVO II mount), it will still fit (providing you buy the 4-bolt mounts and bolts).
NOTE: You have will have to buy the 4-bolt mounts and bolts if they don’t come with your frame.
HS11 is inferior to the HS33. HS33 and HS11 use different levers, but same slave cylinders. I have not used the HS11 lever so I can’t say how good it is, but the HS33 lever is designed to be better (has the pad adjustment dial) and I’ve had no problems with it all.
If you have any other questions just ask.
Hope that helps m8.
The plain HS-33’s are fine (as on my KH-24 which you may have seen at Fluck)
According to the 2006 catalogue the firm-tech are a lightweight version, and will not fit the standard Magura fittings - so don’t bother!
HS-11’s are the entry level system, fractionally heavier and as above, no wear dial which can also be used as a drag brake…
You can also make your own, if you’re slightly handy, by purchasing parts and putting them together. Your KH uni should have already come with the mounts (at least my KH29 did) for maguras, and you can find slave cylinders on eBay for pretty cheap (like $10 each, new) as well as master cylinders/levers in the under $20 range. Hose and fittings can be found at most decent bike shops for not much money, too, so you can put your brand new brake together for under US$50. You can also get a stainless hose kit from Magura for something like $80, if you want to go that direction, and that’ll take care of two sets of brakes.
Otherwise, you can find a cheap used HS11 complete, and just replace the master cylinder/lever to have the equivalent of an HS33. If you’re not interested in the drag brake feature (which I’ve never used, but I mostly muni and don’t often face long (but technically simple) descents, then any master cylinder/lever will work. All three of my unis with maguras have the HS33 adjusters, but I’ve only used them to adjust the pads when I felt too lazy to loosen up the slave cylinder connectors.
Really, the thing to remember is that the brake on a uni isn’t nearly as important as the brake on a bike; all it does is assist your legs in slowing the uni down. Almost any crappy, ratted-out old magura will be up to the task. eBay and observedtrials.net are your friends here!
I’ve used both the HS-33 and HS-11 both onroad and off. I can tell very little difference in stopping power. Both are plenty powerful in the stopping stakes. Saying that the HS-11 is ‘entry-level’ or ‘inferior’ denigrates this brake.
Unicorn - you don’t want the Evo or firm tech versions.
Thanks for all of the help here. I really appreciate it.
I ride very technical MUni and have not found much use for brakes. However I now have a new goal in sight. In Israel just about every major city has an old garbage dump mountain. These Dump Mounds have perfect 60% declines! They are usually about 20 to 60 meters high. About 6 years ago they were all closed down and covered in dirt so there is no issue of stench any more. Keep in mind that Israel has very rocky terrain. Downhills are no problem to find but they are usually quite “snaky” because of all the boulders.
I have started working on the mound closest to my house and I totaly will need breaks. It is just to hard to lock the legs and skid down.
Is the actual evo brake any different? I thought it was just different brackets. The Evo brackets are made to fit on v-brake mounts, with or without a booster, but I thought the brake piston itself is the same. Don’t you just end up replacing the evo bit with the two bolt c clamps?
I have been looking into this issue some. Now I can be wrong, Magura brakes are pretty rare here in Israel, so please correct me if needed. I don’t have any actual brakes to look at. I have been talking to some Trial bikers on this issue. (Trials bikers are probably the biggest users of Maguras.)
It seems like the brake itself is the same when comparing the regular Maguras and the Evo IIs. The Firm Techs have a totaly different attaching mechanism and you would have to have a special fitting welded on to your frame. Avoid the Firm Techs at all cost! AEbikes and MCD (Municycle.Com) both provide the collar clamps that you need for the four bolt mounts when you purchase KH24 or KH29 unicycles from them. We would not use the horse shoe shaped device that is provided withthe Evo IIs. We would also not use the clamps provided with any of the Maguras. We would attach the collar clamps around the brake cylander and then attach the collar clamps to the four bolts on our unicycle frames.
Note the Horse shoe device is what makes the Maguras only good for up to a 2.5" wheel. We should have no problem on the 3" wheel or even on Lagre Marges.
Hope this helps. It would be nice to get confirmation on this.
Your summary seems excellent from my experience of Magura brakes.
I’m not sure that a standard brake would fit a large marge rim - it will probably depend on what tyre you fit. With a standard 3inch Dura on my 2007 KH 24 the straddle hose connecting the two cylinders is pretty close to the tyre. Though I’m guessing that in the UK we’ll need a good bit more mud clearance than you will
If it does prove too short though it should be a relatively straight forward task to extend the hose (providing you know how to bleed hydraulic brakes).
With the large marge, you may need to make/get adapters to move the brake mounts further out? Maguras are supposed to have between 26.5mm and 30mm clearance from the mounts to the rim. If you’re using KH frame say (designed for KH xc or freeride rims), the mounts will be designed for 38-42mm wide rims. That means that with the rim being something like 10mm closer each side, it’ll probably be out of the range of adjustment for the magura mounts.
It might not matter though, you might be able to get by anyway, or by just shaving down the brake pads a bit.
get a rear brake for the spare hose length, it’s a lot easier to shorten a hose than lengthen one!
If you get a pair you could split the (potentially reduced) cost with someone else who wants one, or for a 2nd uni… you don’t need a longer hose for a 3" tyre either.
Thanks for the advice. I am probably going to get a pair because of the reduced price. I can then sell the other one or just keep it for future use. Might even put it on my KH29 even though the V-Brake there is more than enough.
Joe, the clamps that you linked are supplied when you order a KH24 or KH29. Yes, they are needed when mounting Maguras on the four bolt mounts. However the price at the link you supplied is very expensive. UDC US sells them for $15 MDC for 14.9Euro and UDC UK for 12 GBP.
