  Hi,
  I've recently got a new alfine rear hub because i was told they are maintenance free and quiet.
  However, mine seems to make a LOT of noise. The noise ranges from loud clicking noises in several of the gears to general loud humming noise.
  The hub works fine and runs great, however I really want a quiet ride.
  Can you have a look at my video below to see if this noise is normal (sorry for shaky camera -I was changing gears with one hand and holding camera with other)?

  thanks for the tips .
  I've been riding the bike for a couple of weeks now (about 200miles) and the problem persists. I'll have a go at sanding the pads and see if that helps.

  cheers

• Avid BB7 brake disk problem

  I have a slight problem with my Avid BB7 road disk brakes.
  This is the first time I’ve had disk brakes so I’m not that familiar with how they should feel compared to rim brakes. Before I start I should say that I’ve had these brakes ( and the bike) a week now and the pads have been properly bedded in. I’ve also consulted several sources on how to set the brakes up (including Avid’s .pdf file) and I’m confident that I’ve set them up correctly.

  The problem I’m experiencing is that when I’m applying the brakes, it feels like the pads are biting the rotor more positively in some places on the rotor than others. In other words, when I grab a handful of brake it feels slightly juddery and not smooth and consistent like my rim brakes used to. I often feather the brakes on long downhills to just scrub off some speed and it feels like the brakes bite strongly for a second and then less strongly for a second and so on. In other words, the breaking isn't consistent. The same happens when you want to stop quickly and grab more brake: only it’s more pronounced.
  I’ve tried cleaning the rotors with disk cleaner and I’m pretty confident that the rotors are true. I’m at a loss to figure out what it might be. I haven’t actually inspected the pads yet, so maybe this should be my next step.
  Can anyone throw any light on this problem?
  Many thanks
