Why is my cassette making noise?

When a cassette lockring loosens you will experience the loud rattling noise and you will probably feel it, too. Because the cogs are steel and if they’re really loose they’ll be jumping around enough to sound like rocks in a rolling tin can. The other issue loose cogs can cause is poor shifting.

Is R8000 cassette compatible with 6800?

Worthy of note: the new R8000 components are all cross-compatible with the previous 6800 generation and just about any other Shimano 11-speed mechanical groupset. This means that if you’re on a recent 11-speed Shimano road groupset, you can mix and match many of the components reviewed here.

Why does my rear derailleur click?

A clicking noise often comes from your chain wanting to jump up or down a gear on the rear cassette. This can typically be fixed by adjusting the tension of the cable that runs from your shifter to your rear derailleur. The clicking could be caused by a bent derailleur hanger.

Why is my bike making a knocking noise?

A loose headset will sometimes make a knocking sound when the rider stands up during a climb, in a sprint, or under heavy braking. Occasionally, chainring bolts will come loose and create noise especially aluminum bolts. Check all chainring bolts for proper torque. Ride the bicycle.

Can you over tighten a cassette?

Only thing I’ll add is that it is possible to over-tighten a lockring and damage the freehub. Specifically the DT 240S freehub for Campy. The shoulder/flange the cassette tightens against is very thin metal and I did managed to crack one by overtightening.

What’s the difference between Ultegra 6800 and R8000?

Weight. Shimano boasts that, “At its lightest set up (Di2 with mechanical braking) Ultegra R8000 weighs 4,071g, which is an 84.5g saving over Ultegra 6800.” In some formats, outgoing Ultegra 6800 is actually a little lighter than incoming Ultegra R8000.

Is Ultegra R8000 good?

Ultegra R8000 verdict Ultegra R8000 is best seen as an overall refresh of the venerable Ultegra 6800 groupset rather than a drastically new design — lots of small refinements make the groupset an absolute joy to use with braking and shifting that is largely indistinguishable in performance from Dura-Ace 9100.

What is the best cassette for climbing hills?
