sayshell Posted March 4, 2009 Report Share Posted March 4, 2009 I have a 4 bolt booster made of carbon fibre. Instead of buying a 2 bolt I have decided just to saw the 4 bolt. Is it ok to cut carbon fibre or will it frey and stuff? I am doing this just to save weight lol mainly because I can use some short ti bolts. I could just use them with the 4 bolt but then they would be a pain to adjust. Quote Link to comment Share on other sites More sharing options...

Muel Posted March 4, 2009 Report Share Posted March 4, 2009 If you only doing for weight, don't bother, you'll save about 10-25gs.You need to be really careful when cutting it not to splinter it, so you have to use really fine hacksaw blade, and then find a way to seal the open cut.So I'd just leave it if I were you.

forteh Posted March 4, 2009 Report Share Posted March 4, 2009 (edited) just leave it as a 4-bolt, the amount of weight saved is going to be ridiculously small...also carbon fibre is notoriously hard to cut, ..If you do decide to do it, a very fine ( high tpi ) hacksaw, or dremel with a cutting blade would be best.NOTE: the dust is quite harmful if inhaled, so it'd be worth wearing some kind of respiratory protection liek aface mask.Pretty much what he said The weight you save will be absolutely minimal (unless its really silly thick carbon), however if youre insisting on cutting it then you can use a very fine pitch hacksaw or even better a cutting disk. The edges shouldnt splinter with the cutting disk but it may with the hacksaw, if it does splinter I believe you can rebind the loose bits with superglue.The dusty is nasty - get a mask Edited March 4, 2009 by forteh Quote Link to comment Share on other sites More sharing options...
sayshell Posted March 5, 2009 Author Report Share Posted March 5, 2009 the results....i decided to saw it with a hacksaw. The first side turned out fine, its easier to saw than aluminum just the blade sticks sometimes. The second side splintered cause i sawed 9/10 through then just broke the remaining piece off. I filed the burr it left and it looks the same as the first side. Carbon fibre seems more close to metal to me than like a wood material with grains and stuff. It seems like i can just file it to whatever shape i want. I am overall glad i did it. Now my fancy red magura mounts are more visable, the booster is slightly lighter, the bolts are shorter/lighter, and its mechanically easier to maintain and gives the same amount of brake power.

mr_malcolm Posted March 6, 2009 Report Share Posted March 6, 2009 biggest waste of time i have ever heard of. I mean sure when you are riding you are obviously going to notice all that weight saved. . . . . Quote Link to comment Share on other sites More sharing options...
Fixed Pants™ Posted March 8, 2009 Report Share Posted March 8, 2009 biggest waste of time i have ever heard of. I mean sure when you are riding you are obviously going to notice all that weight saved. . . . .!0 grams here, 10 grams there, maybe you'll end up with a decent percentage of the bikes weight lost... If it's a light bike in the first place. Quote Link to comment Share on other sites More sharing options...

tris Posted March 8, 2009 Report Share Posted March 8, 2009 You'll save more weight taking off your jumper. What the f**k is this weight obsession all about. Tuh...... Quote Link to comment Share on other sites More sharing options...
Muel Posted March 8, 2009 Report Share Posted March 8, 2009 Bikes wear jumpers these days?Lighter bikes are easier to ride, it's pretty much a fact. It doesn't make a huge difference when you only do one move then stop and chat for 5 mins, but when you actually ride sections it makes a huge difference.
