J Trials 31 Posted December 8, 2011 Report Share Posted December 8, 2011 As the topic says, is there a way you can determine whether you should use a booster? Or should you just always have one on hand to try. Quote Link to comment Share on other sites More sharing options...
dann2707 Posted December 8, 2011 Report Share Posted December 8, 2011 If your brake is slipping when on an edge of the wall its likely your frame is flexing and the power you are putting through the brakes is actually pushing the frame out rather than pushing the pads against the rim. I prefer a 2 bolt booster rather than a 4 as it doesnt make the bike too stiff, retaining a nice honk from the brake pads. 4 are trickier to set up too. You might not even need one as some frames have them built in. Quote Link to comment Share on other sites More sharing options...
davidbarr Posted December 8, 2011 Report Share Posted December 8, 2011 If you can see your frame flex when you pull your lever in hard, then you might want to be running a booster As Dan said, sometimes with a 4-bolt booster can make you lose quite a bit of bite. More hold though. Quote Link to comment Share on other sites More sharing options...
konstant Posted December 8, 2011 Report Share Posted December 8, 2011 Just look to see if the frame is flexing. Yeah, better hold usually at the expense of a little bite. I noticed with my new frame that the brake felt really positive at first, but a few months of riding has softened up the rear triangle to the point that I now want a booster.

Revolver Posted December 8, 2011 Report Share Posted December 8, 2011 It's all about 2 bolt boosters. They're easier to set up. I modified my tensile booster, tarty say it's the stiffest 4 bolt booster you can get. For the sake of ease I used to just run the top two bolts. I cut the bottom off later cause it makes it easier. Anyway, yeah, unless your frame is ridiculously flexy - my ciguena for example used to flex out at pretty much the same rate as you'd pull the lever - get a 2 bolt booster.

J Trials 31 Posted December 8, 2011 Author Report Share Posted December 8, 2011 Yeah my Zm2 is pretty flexy, I figured I needed one. Hoping to hold out for a TNN one but their pretty pricey, hard to find, and no one seems to want to let there's go haha Quote Link to comment Share on other sites More sharing options...

Ross McArthur Posted December 9, 2011 Report Share Posted December 9, 2011 To all, think you would notice a difference if you used a 4 bolt booster and only ran the two bottom bolts (like a V booster) as apposed to running a two bolt booster and having the two top bolts in the frame?

I've done this! It works as running top two was to stiff and without was to flexy, used in bottom two bolts was brilliant!!_ Quote Link to comment Share on other sites More sharing options...

Simpson Posted December 9, 2011 Report Share Posted December 9, 2011 As long as it works. Its a hunk of metal to stop your frame flexing, no "design". any of Tarty will be fine. Quote Link to comment Share on other sites More sharing options...
