Superstar rear hubs...some thoughts

The Rookie

Have just fitted some new (to me) Superstar wheels with the Superlegera rear hub (with Trizoid free hub), pretty happy with them, but some thoughts come to mind.

1/ The cassette sits much closer in to the frame centre line than on any other wheel I've had on my bike, the other three all sat in a similar place, but the Superstar hub sits the cassette in by almost one whole gear (9 sp).

2/ This has a side effect in that the drive side wheel bearing sits a long way in, in fact it's just about level with the edge of the rim, while the NDS bearing sits a long way further out - guess which is going to fail first! Yes it had failed on mine while the NDS and freehub bearings are perfect and didn't need changing.

3/ I have noticed a propensity when using the lowest gears (1x9) for the chain to want to try and ride off the inboard side of the chainring as the cassette location means it runs a worse chain angle than on the other wheels I've used, chainangle is not equal (but opposite) in highest and lowest gears.

So I'm thinking of swapping a driveside spacer to the NDS (Shimano HT2 crankset) to equalise the chainangles.

Thoughts/opinions?

Be careful the driveside crank doesn't come into contact with the stays (bearing flex in mind too) and also take into account andy linkages on the upward stroke... but... moving the chainset in sounds like it would solve tha chainline issues. Good luck!

That sounds like it should work, i can't think of any issues unless the front mech becomes outside it's range of adjustment but it's only 2.5mm so shouldn't do.

It will work assuming the cranks clear the frame.

HOWEVER...

your knees really wont like it. I had to do this on my commuter to get the singlespeed chainline I needed and it played merry hell with my knees. Personally I'd suggest spacing the chainring in with some spacers and possibly slightly longer bolts.

I had to do this with my HD to get it to work with my chain guide and have had no problems in all honesty, knees included!! It's a bodge, but as bodges go it should be a decent one and it should work just fine.

I'll be giving it a go, no issue with front mech as it's a 1x9 (as stated) and as the ring and guides are all crank mounted they have to move together! Annoyingly it all worked fine on my Ritcheys!

just a thought, the hub has definitely been assembled right?

Yep, this is a common theme from people using the Superlegera rear hub, there have been at least 2 posts about it in the last few months, including one from cube_crazy.
