Have any of you experienced a ticking sound in the Crank or BB area of you Mach 4's? the ticking sound appears on a certain area which the pedal rotates and it becomes even worse if you pedal standing on the bike... I hope its not a broken BB.

I'm having it check at my Local bike shop... will post for results once I get my lovely mach 4 back.

Most likely your BB bearings (a minor, easy to fix problem). I can't imagine it anything else.

As an aside, pretend you travel back to year 2000. Your BB tapered spindle either breaks off or strips when you do something like a 5' drop... and a big travel bike is the Heckler :lol: XC is only XC if it's a hard tail, TBW. :p

Creak

In my experience creaks can originate from any point on the bike and sound as if they are coming from the drivetrain. It's a pain, but you'll have to check everything to eliminate the variables. Plus it's a good time to clean and inspect your bike. Check and grease the seatpost bolts. Check the chainring bolts (a very common one) and move on down the line.

If you eliminate the component variables and still have a creak, then move on to the frame. If you tighten any bolts on your Pivot, make sure you use a torque wrench. Torquing them back to proper spec may be all you need. The torque spec chart is on the web page under the Tech button. Make sure to prep the bolts according to the chart. If it calls for anti-sieze or lock-tite, do not use grease. The only reason I make such a big deal out of this is I have seen the effects of the "tighter is better" mentality and they aren't good. Don't just go reefing on those bolts. It's a precision machine - treat it right.

I had too many beers last night and forgot to put that I had this problem once right before my hub cracked in half. So check your hub :)

Thanks for all your informative replies, I finally got my lovely Mach4 back from our LBS. Seems that some dirt and tiny rocks got its way inside the BB, I also had the Chainring bolts checked and tightened. Will try out if the "Ticking" sound is already cured this weekend in our local Trails... Will let you know if it solved the problem.:thumbsup:
