[Closed] New Hope hub problem? Please help!

Hi All,

I have new Hope Pro 2 Evo's on Arch EX. They've performed exceedingly well for the week I've had them until today. I'm not sure what's going on...

I have also just put on a new chain - KMC Gold 9 speed. Sure it fits ok but didn't take any links out, seems to fit - How to check?

The problem is... When I shift into the lower/harder gears, the hub [i]feels[/i] like it's slipping. It feels like the insides of the hub are slipping somehow. This only happens in the last 3 gears.

What I'm thinking though is that it couldn't be the hub - maybe I need to tune the gears again? They seem to change OK but then start to slip in lower gears. I've never felt this before and it happened as soon as I put the new chain on.

Any ideas people? I really need to sort this before tomorrow's big ride in the woods. 🙁

Optimum chain length = wrap it round big front & big rear (not through dérailleur) + 2 links.

How old is the cassette? Sounds like its too worn for the new chain to me. Unlikely to be the hub.

harder gears are higher gears.

Worn cassette is my bet.

What rondo said.
mate of mine slapped a new chain on straight out of the box, I took about 6" worth of links out, sorted.

You may need a new cassette & possibly chainrings.

As above, new chain skipping on worn cassette.

Shortening the chain may mask the problem until the chain wears a little, but its more likely you will have to replace the cassette. Or the cheaper option, put the old chain back on 🙂

If it doesn't do it with the old chain then there is nothing wrong with the freehub. Count the amount of pins on the old chain and cut the new chain to the same length. If it still slips then it's new cassette time. I'd also check the front chain rings.

Thanks all - New Renthal 34 front and 3 month old XT cassette. Chain is too long, going to use the rondo method.

CHEERS ALL! 😀

aye probably just too long chain that can't be tensioned by the derailleur properly.
