Hi guy's,

recently picked up a new Gas Gas which has an iris chain as standard. Randomly came across a topic on here regarding the iris chains snapping etc and potentially causing damage to me and my bike so figured i'd replace it with a quality chain before it does!

The question is, which one?

I see renthal do the r1 and regina do a standard chain which most are branding as a trials chain.

I had a regina fitted to my beta as standard which was great but it didn't have gold outer links so not sure which model it was?

From what i can make out the renthal is going to be the stronger of the two but i don't want to create a huge amount of drag on the back wheel, do they make a noticeable difference over a standard weight chain?

Thanks

Hugh

Never let me down (in normal circumstances)

Most trials riders opt for a non O ring chain. It's the O rings that allegedly cause extra drag.

I have the Renthal R1 - it's a treat.

Renthal all the way and get some nice stickrs

The Renthal R1 chain is manufactured by Regina, but Regina do not market an identical chain.

I use Renthal R1, don't think you can get better.

Yes, I also heard Rentha chain is made by Regina. Good stuff.

The Renthal can be a pig to get hold of and I've found the RK MXZ4 520 to be a really tough chain. Available in standard gold, red and Green.

Thanks guy's,

went with the renthal, also found some older topics all recommending the same.
