broken u-turn knob on rockshox recon

[Cletus]

hey guys, i just picked up my new xc bike on saturday and while i was setting it up i noticed the u-turn knob on my fork had a heap of big cracks in it and it would'nt adjust the travel at all. my lbs was great and got straight onto getting me a new knob but i was just wondering if anyone else has had this problem?
the knob looks pretty weak and im hopeing its not somthing that breaks all the time.
any recon owners had any problems?

oh and do they usually make a loud whooshing sound when you compress the fork? mine are

yes i had my uturn knob replaced, the plastic ones are crap anyway.

and yeah the wooshing is normal.
it's the oil rushing through the motion control assembly.

you can get alloy knobs on some rs models. theyre heaps better!
i got a replacement platic one tho as that was easiest.

thanks guys, i might look into getting the alloy knob.
and thanks Mo for answering the question about the whooshing sound, im glad thats normal because it was freaking me out. i hope it does'nt get to annoying out on the trails though, it's pretty loud.
