New rear wheel, rear derailleur fouling spokes

[confusedcyclist]

Off the back of this thread I have ordered some new wheels - this Shimano R501 wheelset so I can get up and running while again while I rebuild the old wheels, I figured I'd quite like set of spare wheels anyway.

The rear wheel is supposed to be 10 speed compatible but my 105 rear derailleur is fouling the spokes. It's only slightly but enough to make me worry about being dragged into the spokes in the event of a bump. This wasn't an issue on my stock P-Elite C wheelset so I don't think the alignment is out, however I did drop the bike on the drive side, so I'm not ruling it out, but with the naked eye its not obviously out of whack, the clearance to the spokes is 0mm!

I could change the limiter screw to bring in the rear mech further in, but concerned about losing the outer cog. Any idea what might be going wrong here? It's a new wheel so I wouldn't think the dish would be out, and the wheel is loaded correctly in the frame, rather annoying as I was rather looking to get back out on the road bike!

Adjust the limit screw and if all works fine then ok. Worry about mech alignment if it doesn't.

Continuing to ride it like it is is a disaster waiting to happen.

Is it also 11 speed compatible and possibly you're missing a spacer.

Put a spacer on before the cassette as mosquito says.

Get the alignment of the hanger checked, they are designed to bend.

As @Smokin Joe says, tighten the hi limit screw now. Better lose a gear than the mech, your wheel and possibly your health.

Then figure out what to do

Edit. the lo screw not the hi screw. Duh

Unfortunately the rear is not 11 speed compatible, having just fitted the cassette I know there is no way a spacer would fit. thinking about it logically, it's either just the lower limiter is just too far out, or the derailleur is bent. Rather annoying that the wheels are that different. I have just realised that should I want to change the wheel's I'm going to have to adjust the rear mech every time! ARGHH!

If the low gear limit screw were to be too far out, but the shifter still delivers the last gear properly without it grinding or wanting to overshift, then turning the screw in will not solve the problem. Turing it in to sacrifice the last gear is a good idea for now though, for reasons stated above.

However, you don't say when the derailer connects with the spokes. Is it whilst just turning in the workstand or when standing and pedaling? There are two different solutions depending on your answer.

I have only tried in the stand so far, will report back later if it's an issue while pedalling, though I assume it is given the lack of clearance..

No, don't even try. Something's amiss. Have a mechanic with a hanger gauge check it out.

I would also get someone to check the spoke tension of the new rear wheel. As the problem has occurred since the new wheel was fitted it is worth a look to see if the spokes are slack.

The RD is not bent is it ?

 

[adscrim]

Is the wheel sitting properly in the frame?

Cheers, I've ordered the Park Tools alignment tool, considering my other bike just came back from the LBS for hanger alignment I think it’s about time I invested in the hanger tool. I'm not in the habit of having mechanics look at things unless I'm stumped! Watch this space!

Not sure, will know soon. It's was shifting perfectly on my last set of wheels.

Is the wheel sitting properly in the frame?

Definitely!

Thanks, I'll give those a look over too!
