Brake Question Mr. Grumpy or Frog Legsmosovich

Okay, I've currently got the Mr. Grumpy's, had them two years, but they just plain out suck. How are the Frog Legs? Do they just slow you down, or actually stop you? Anyone had experience with both is appreciated.

I think maybe you expect too much from your canti's. I don't know if any "stop" you as good as vees or calipers, so if this is what you are expecting your only solution would be the Maguras.

I had a similar experience with Spooky's. They just did not seem to have any power. I switched to a set of old Avid Tri-Align 2's and they work quite a bit better but still not nearly as good as a set of Vee's. For racing though you don't really have to have alot of brake power as compared to brake FEEL so what I have now does the job just fine. If, on the other hand you are riding your cross bike on trails with alot of steep descents you may want to do as the other poster suggests and switch to magura's. MORATI

exactly. Look at the pro's most are riding Froggleggs and Grumpy's and they all seem to do fine. You just have to adjust your head. It's like complaining because your felt pen can't put down as much ink as your airbrush. They are different tools with different performances so most of the weirdness is mental. I mean do you complain because you can't do 3 foot wheelie drops on your cx that you can on a FS rig?

Try replacing the brake pads with a higher end brand. I too have experienced poor stopping power from the brakes on my cx bike, but a switch of pads has made my cantis as powerful as the DuraAce brakes on my road bike. Try KoolStops or Ritcheys.
i agree.. koolstops improved my braking 50% (nm)markNc

with the stock Ritchey "red" pads in them and they work fine. Have had them for 2 seasons. I can skid the rear wheel no problem and get plenty of brake shudder on the front from the power.

In cross, you don't need more brakes, you should be going faster.
Fiddle with Set-uptriangleforge

You probably won't have any better luck with the Empellas, since the geometry (though not the design) is pretty similar. But be sure you've exhausted every set-up option before you give up on the Mr. Grumpies. I fussed for a very long time with the Spookys (which are very much like the Frog Legs) before finding the right combination of pad material, straddle cable height, and pad placement. I'm very happy with the performance now. Here are a couple of things to try before you ditch the Grumpies:

Start with optimal pad placement. Since these don't allow you to shift the pads up & down (I think), you'll need to start with whatever placement of the post puts the most meat of the pad on the rim. It's pretty fussy to get this just right with my Spookys, but worth the effort. I found that I don't want the pad, when it contacts the rim, to be reaching "up" any more than it has to.

Try a higher straddle cable -- it's counter to what I always learned with lo-profile mountain cantis, but a higher cable will have you pulling at closer to 90 degrees.

Try a wider straddle hanger -- again, this was always a way to make it easier to modulate excessively grabby lo-profiles, but on long-arm cantis, it gets your leverage more into play. I'm using Ringle Mojo hangers, but it would be even better with some of the old Shimano wide saddles. I've go some, but vanity just won't let me part with the Mojos...

FWIW, I really like the salmon-colored Kool Stop pads with my Spookies.

Good Luck!

Thanks for all the tips. I think I'll try new pads. Right now I'v got some gray ones that have a real hard compound. I may get some red ones tomorrow. I was just curious. I mean hell, your racing, not stopping! Happy Crossing!
