LauraPalmer Posted August 18, 2010 Report Share Posted August 18, 2010 As the thread title says, but i only want to hear about high quality sprockets - cheap 3/32" don´t hold up, but do surly and trialtech (or anything else)? I´m a 85 kg rider who forces his drivetrain a lot, but my Surly 1/8" managed to show no signs of wear, after about 2 years of riding (changing chains every three months or when they stretch more than 0,7 mm in 10 cm)... As a sidequestion - has anyone noticed a diference in wearing between them? why am i even asking: I´m running a 1/8" Surly on the rear, due to very fast wearing of cheap or Chris King cogs(far too soft material) and so I´m forced to run z510hx chains (which i love), but i could get Z610HXs very very cheap so I´m thinking about switching... second question: does it really have effects if you use a 1,375x24 on a 1,37x24 thread? I never had problems with TA cranks and an ENO (using that setup quite long now), anyone ever had problems with let´s say the Surly cog which is 1,375x24 (on Tarty it says 1,37 but I´m pretty sure this is not right) and a TA H135 hub?

AdamR28 Posted August 18, 2010 Report Share Posted August 18, 2010 Sprocket width makes no real-world difference with a good sprocket like Surly/Trialtech. I've never seen a Surly/Trialtech sprocket worn out, ever! Surly website lists the sprockets at 1.375" however they measure the same (33.75mm minor thread diameter) as all the 1.37" items (freewheels, other sprockets) we have in stock, and less than ENOs which are around 33.85mm+.

Dan Clark Posted August 18, 2010 Report Share Posted August 18, 2010 I clearly own the only worn out Surly sprocket in the world then Quote Link to comment Share on other sites More sharing options...
LauraPalmer Posted August 18, 2010 Author Report Share Posted August 18, 2010 did you ride it with a lengthened chain? Quote Link to comment Share on other sites More sharing options...
Dan Clark Posted August 18, 2010 Report Share Posted August 18, 2010 No idea, it came on a wheelset I bought but wouldn't fit at all with my new chain. Not saying the sprockets are bad or anything, it was a brand new chain and an old sprocket. Quote Link to comment Share on other sites More sharing options...

Dan Clark Posted August 18, 2010 Report Share Posted August 18, 2010 Unfortunately it's in Leeds, and I won\t be there for another month or so, if I remember I'll whack some up. Quote Link to comment Share on other sites More sharing options...
