tmusson Posted November 6, 2009 Report Share Posted November 6, 2009 Just been looking on tartybikes at the disk rotors. Was looking at the rockman one mainly, they say the holes help the pad bite to them? Shurly more surface area would make more friction and then better braking?

Ben John-Hynes Posted November 6, 2009 Report Share Posted November 6, 2009 So you're going to argue with Tartybikes? The holes keep it cool, too. Quote Link to comment Share on other sites More sharing options...
tmusson Posted November 6, 2009 Author Report Share Posted November 6, 2009 More surface area makes more friction FACT! Also more for the pad to grip to. Cant see it getting that hot with trials riding. DH yes, trials no. Quote Link to comment Share on other sites More sharing options...
josh barker Posted November 6, 2009 Report Share Posted November 6, 2009 ^^^ Yes Bens right the more holes you have, the more cooling you have therefor your pads have less chance of glazing over.Shurly more surface area would make more friction and then better braking?Its not the rotor what just makes the brake more powerfull its the diametre of the pistons just as much actually.What rotor are you running now.

Would a 160 be to small for stock? Quote Link to comment Share on other sites More sharing options...

Would a 160 be to small for stock?Yes, a 160 would actually be too small to be honest. Maybe a 180 would suit a stock better, yes the Rockman rotors look good but they look a bit on the cracky side.

Would a 160 be to small for stock?If you're talking about the front then the 160mm may not be too small, depending on your riding style. If you like bite and lock then yeah it'd be too small, but if you like a bit of modulation it'd be fine!If you're talking about the rear, I tihnk a 160mm BB7 would be far too small.

I will stick with 180 then as it does lock and bite well. my mate has a 160 with his hope on stock and it feels ok. Quote Link to comment Share on other sites More sharing options...
Ben John-Hynes Posted November 6, 2009 Report Share Posted November 6, 2009 Yerrr a hope should be fine, or better than a 160 bb7 anyway Quote Link to comment Share on other sites More sharing options...

bogdan_vtt Posted November 11, 2009 Report Share Posted November 11, 2009 160 front, on stock - doesnt recomend, no matter the disk type. On mod maybe. Quote Link to comment Share on other sites More sharing options...
