Sprockets

I'm thinking of running an Ironman 50T rear. A while back I heard some talk of Ironman's design leading to hub failures. Anyone got any data to support or disprove this claim? :thumbsup:

No problems with my Ironman's. Just be sure to properly torque the bolts and check them from time to time to be sure they aren't coming loose. Some guys say you should replace the bolts each time you replace the sprocket- I didn't and haven't had any problems.

I've been using them myself for a while (just about a year) and no problems so far. Most of my friends are also using them.

I don't know if the design of the Iron Man sprocket had anything to do with it but mine tore all the mounting holes off the hub. I'm pretty sure the damage was caused by loose sprocket bolts because I had just retightened them after they loosened up. The sprocket was only two rides old. Now it's a steel pretzel.

From now on I will:

1. Not re-use old sprocket bolts.

2. Use loc-tite on the threads.

3. Check the bolts often for the first few rides.

4. Use only Iron Man sprockets.

If your gonna spend $80 on the sprocket go ahead and pay the 12 bucks for the new bolts or at least new nylock nuts.

Hope this helps. later,

I have had mine for almost 2 seasons and they show no, and I mean no signs of wear. Alot of people that ask about them can't believe I have had them that long without any wear. No hub failure here.

Love em! Second season and 0 sign of wear. Hub is great and didn't replace with new bolts. :thumbsup:

Amen - also when you loc-tite - let it set up for 24-48hrs before riding - gives adaquate time to dry - If you retighten after they are dry, you will break the seal and you must replace with new loc-tite (I use Red 242) after your ride - otherwise they will always loosen (they will wear the holes to ovals) and damage to hub is imminent, even if you forget to tighten just 1 time....many with hub failure will attest to this! I replace bolts and nuts for each new chain and sprocket - they do stretch...

IronMan on mine - no signs of wear at all - best sprockets for longivity! :thumbsup:

Personally I think my Sidewinder is better than you're Ironman.....

But that's just me....
