AlexClare94 Posted June 14, 2014 Report Share Posted June 14, 2014 Right so I see a fair few bikes with rear brake boosters, I know they protect your cable and that some frames have them built into their design but is there really a need in that extra bit of weight to compensate for breakages?

harmertrials Posted June 14, 2014 Report Share Posted June 14, 2014 I never run boosters, not a fan. Quote Link to comment Share on other sites More sharing options...
niconj Posted June 14, 2014 Report Share Posted June 14, 2014 No not necessarily Why? If the frame flexes, isn't a brake booster helping reduce it and put the pads with more pressure on the rim? Quote Link to comment Share on other sites More sharing options...
harmertrials Posted June 14, 2014 Report Share Posted June 14, 2014 A booster tends to give more hold, with a quieter sound. But personally I like a bit of flex to get a lot more bite and 'honk'. Never had an issue with a lack of hold. Quote Link to comment Share on other sites More sharing options...

harmertrials Posted June 14, 2014 Report Share Posted June 14, 2014 What's bite and hold again? Isn't that obvious? How well the brake bites - the speed it stops. Hold is how well it holds the wheel in place. 1 Quote Link to comment Share on other sites More sharing options...
jack dickinson Posted June 14, 2014 Report Share Posted June 14, 2014 i have a booster, don't use it though. fitted it, and hated it. also it's just a fath i fint it hard to sut up my brake as it is...... Quote Link to comment Share on other sites More sharing options...

When are you actually stopping speed? I don't usually skid when on my trial bike. Hold would be pedaling up some obstacle and when landing on it, how well the wheel stays still?

Jake. Posted June 14, 2014 Report Share Posted June 14, 2014 I think the only frames that ever needed boosters were old school frames that didn't have much strength. Everything is so compact nowadays, and a lot of frames seem to have built in boosters or a very stiff back end at least. Quote Link to comment Share on other sites More sharing options...

shercofray Posted June 14, 2014 Report Share Posted June 14, 2014 When are you actually stopping speed? When you land on an object you want the wheel to stop instantaneously. I don't usually skid when on my trial bike. Hold would be pedaling up some obstacle and when landing on it, how well the wheel stays still? Hold relates to how well the brake holds the wheel in palce once it has stopped. 3 Quote Link to comment Share on other sites More sharing options...

Everything is so compact nowadays, and a lot of frames seem to have built in boosters or a very stiff back end at least. the echo pure lite 24 etc have bad flex, and the onza frames without integrated boosters. i know i had horrible flex on my echo pure and onza comp frames. still never ran a booster though. i still get a little bit of flex even on my radix but not on the tubes but on the brake mounts if you get what i mean? it's not a problem though Edited June 14, 2014 by jack dickinson Quote Link to comment Share on other sites More sharing options...
Jake. Posted June 14, 2014 Report Share Posted June 14, 2014 Mine even flexes a little with a Trialtech 4 bolt booster. I don't know whether the brake is "too strong" though. That's because as soon as the brake hits the rim the force can go nowhere else apart from flexing stuff... the echo pure lite 24 etc have bad flex, and the onza frame without integrated boosters. i know i had horrible flex on my pure and comp frames. still never ran a booster though. i still get flex even on my radix but not on the tubes but on the brake mounts if you get what i mean? it's not a problem though I LOVED echo frames without boosters, gives such nicer lever feel and always gave the best braking performance for me.

Jake. Posted June 14, 2014 Report Share Posted June 14, 2014 What brake set up did you use if I may ask? Cousts, 4 finger 05, and echo tr. Worked a dream. Quote Link to comment Share on other sites More sharing options...

Worked a dream. cousts (french ones), magie 4 finger blade. and deng sl cnc'd lever body and maggie slaves. (same setup for both the comp and the pure) had not bite or hold. but change to heatsink yellows and was signifcantly improved. now on the radix it's. heatsink yellows (because im to lazy with grinding my rim.) tar. maggie 05 four finger and maggie slaves Edited June 14, 2014 by jack dickinson Quote Link to comment Share on other sites More sharing options...
Blake Posted June 14, 2014 Report Share Posted June 14, 2014 Echo 24's are solid what you saying The only frames I've thought a booster needed is some of the onza's, like the onza comp or t pro Quote Link to comment Share on other sites More sharing options...

dngr2self Posted June 14, 2014 Report Share Posted June 14, 2014 I like to use a 2 bolt just to take any flex out of the brake. How I see it is that even if the frame doesn't flex the brake still will. If you think about how the brake fits to the bike it must be able to move.

Bint Posted June 14, 2014 Report Share Posted June 14, 2014 most of the time Less vibration = less bite, so not really making your brake better, may give better hold but that isnt gonna help if your taking off on a slope. Quote Link to comment Share on other sites More sharing options...
