I've had luck with messed up crankarm/pedals by putting the pedal in the back side of the crank to try and chase out the threads, then put them back in properly on the front side. look for areas where the metal was too thin and it actually ripped and collapsed inside the crank arm.įYI, if the crank's aren't damaged, and only have some messed up threads. Possible issue with an bad drill/tap at the factory, and only a good photo from the back side, or of the inside of the crankarm thread will help. Since the pedal that came undone was the right side pedal, it uses normal right hand threads, so the argument of "did you put it in backwards" is hard to justify.
If you're 100% sure you screwed the pedals in right, that they were tightened down, then I'd fight back, tell them you expect a replacement crankset with removable rings of comparable quality. Since you assembled it, it unfortunately is a case of he said/she said, which is impossible to determine whose right. Just looked up your other thread where you showed the picture and discussed talking with DB.
For the price of the suntour, I'd bump it up a little bit more and get a new external bearing crankset. The suntour has replacable chainrings, which would allow you to use a narrow wide ring in time, or simply replace the 32T chainring when it wears out. For the price, still not a huge difference. Look up on their respective websites and look at the crank datasheets to see what bottom brackets they recommend.Įdit, the suntour one is actualy a better crankset (I was thinking of the Alivio and Acera cranks, not Altus). Light weight and durable entry level XCE T312 crankset. They offer great stiffness and durability and are compatible with bicycles with an 8-speed gearbox with a square bracket axle. Ubuy is the leading international shopping. SR Suntour XCE T-312 cranks are perfect for riding on mountain and mountain bikes. I'm not sure what each of those cranks require, but an initial guess, they both require different bottom brackets. Buy SR Suntour Crankset Srst Xce 170X48A-38S-28S Sqr W/Cg (G) - CW16-XCE-T328SQ online at an affordable price. Otherwise, you'll have to re-position and adjust your front derailure.Īlso need to make sure you get the right bottom bracket to work with the crankset you're getting.
If your current setup is a 42T, stick with 42T on the new one. It will also depend what's on your bike now. I'd go with the Suntours because they have the 44 vs. both are low-mid end standard square taper cranks. That link shows a chainguard that is helpful in preventing a chain falling off the outside during a shift to the big chainring.Their about the same. The "bashguard" in that link is made of plastic and would shatter if you bottomed out going over a rock. The bashguard, being larger in diameter than the largest chainring absorbs the impact. Bashguards are robust and designed to protect your outer chainring on rocky trails when your chainring would have hit a rock as you were going over an obstacle. Link to who has that crank containing the BG in place? I'll gladly send out another email.You have to be clear about the difference between a bashguard and a chainguard. Asking the forum is where this ended me at for finding that information.
