Could somebody point me towards a good V-Bake caliper that i can use on my Onza RIP as i have broke my rear one. I was going to buy the Avid SD7 off Tarty Bikes but they don't have any in stock: http://www.tartybikes.co.uk/product.php?pr...category_id=109 So what other brakes would be ok to use on a trial bike? i was thinking these: http://www.chainreactioncycles.com/Models.aspx?ModelID=20678 But I'm not sure how good there hold would be or how strong they are as they are made for mountain bikes, not trials bikes.
