drca Posted June 12, 2017 Report Share Posted June 12, 2017 2013 TXT Pro 250 Just found that my chain has some stiff links and is showing some signs of rust. So time for a replacement. What do people use / recommend? I'd like to go o-ring (or x-ring...) but I am concerned that the o-ring type chains are wider than the regular chains and will cause problem with the chain guide. Thanks. Quote Link to comment Share on other sites More sharing options...
sirdabalot Posted June 12, 2017 Report Share Posted June 12, 2017 I tried an RK O ring, too wide for the guide and there may be clearance issues at the gearbox sprocket/case area. Quote Link to comment Share on other sites More sharing options...
midlife Posted June 12, 2017 Report Share Posted June 12, 2017 Renthal r1 chain . Its not o ring but it lasts Quote Link to comment Share on other sites More sharing options...
mcman56 Posted June 12, 2017 Report Share Posted June 12, 2017 I run X ring chains and they last forever. They are not as wide as o-ring. V-mar makes a nice wide chain guide. A little trimming can make a standard guide work also. On my Rev 3, I had to put the master link clip towards the inside to avoid it touching the brake pedal http://www.vmar.com/chain-guide.html Quote Link to comment Share on other sites More sharing options...
jrsunt Posted June 12, 2017 Report Share Posted June 12, 2017 I've snapped them all in the Scott, even when new. The only chain I will use now is the DID ERT2. Not cheap but worth every penny. The last one has done 2 Scotts. Quote Link to comment Share on other sites More sharing options...
fourex Posted June 13, 2017 Report Share Posted June 13, 2017 (edited) I've never considered an 'O' or 'X' ring chain for my Trials bikes, I don't see the need personally. I've always enjoyed good longevity from Regina chains. Just out of curiosity I found the following............ DID 520 ERT2: 17.60mm width and 36000 Nm average tensile strength. DID 520 ERS2: 16.75 and 25900. Regina 520 135EBXL: 15.875 and 26900. All non O or X ring, the DID 520 ERT2 is certainly a stronger b@$t@rd, just depends on whether your bike can accommodate the width of 17.60mm without rubbing on something? Edited June 13, 2017 by fourex none of your business. Quote Link to comment Share on other sites More sharing options...
andrewmorpeth Posted June 13, 2017 Report Share Posted June 13, 2017 Agree DID gold/gold chain.Better than renthal.I get a year out of mine with v little maintenance! Quote Link to comment Share on other sites More sharing options...
drca Posted June 13, 2017 Author Report Share Posted June 13, 2017 Thanks for all the replies. So I ended up ordering a RK standard chain (I've been pretty happy with RK chains before and it was cheap < US$30 on Amazon Prime) and some good lubricants. I am in Northern California so 8 months of the year we don't know what rain is, and the rest of the time it's too wet to ride... Hoppy trails.

cascao Posted June 14, 2017 Report Share Posted June 14, 2017 I like to change the sprockets and chain at same time. Quote Link to comment Share on other sites More sharing options...

I have sprockets on order... my question was really about the type of chain, but thanks for the reminder. 1 Quote Link to comment Share on other sites More sharing options...
