    upgrading from V's

    Have a 2000 Kona Muni Mula and love this bike. Still running Avid V’s and I would like upgrade to disc. Cannot decide between shimano SLX hydo’s or Avid BB7 mech’s. I like the BB7’s for their simplicity but they really do seem bulky and maybe ‘old’ technology. There’s also the question….how much do I spend on upgrading this bike. I’ve already upgraded the rear derailleur with a new XT and the cranks to LX as well as new stem, bars, selle saddle etc. Will either purchase crossrides or red metal 5 wheelset with the disc conversion.
    Any suggestions?

    Excellent idea to upgrade to discs.

    To me your decision is a no-brainer - go for the Shimano. Although mechanical discs are much better than they used to be, hydraulics are still better and SLXes are excellent, almost as powerful as the XTs and only a little of the fade/pump that still bothers Deores on long downhill trails.

    How much do you spend on upgrading your bike? I would pu as much money as possible into your brakes, and less into drivetrain, because I like being able to stop in a hurry. But if you're into racing and need to have fast reliable shifting, you may think differently.

    Good luck with the new brakes!

    I really like my BB7's. I know hydraulics are better, but I wouldn't walk from here to across the street for the difference between them-for what I do. They have all the power I need and I didn't spend a lot of money. Ride a bike with both and compare them if you can-might surprise you how good the bb7's are.

    Doing the full disc can be $$$. If you want to go halfway, then the BB7's are a great choice. You upgrade the wheels and buy the quite cheap cable disc calipers and simply re-cable the bike - easy.
