Iv'e heard that the single didgit 7's are great v brakes. I've also heard that the ultimates are really good as well. I have an oportunity to get a brand new rear ultimate for 70 bucks or a brand new 7 for 35. is it worth it to get the ultimate? I'm not sure if its worth it to shell out the extra cash. let me know what you think about it. also what kind of pads should i use for the best stoping power, I will be using them on my new desalvo with ground and tared dx 32's. any info will help. thanks!
