I have 38mm sixth element on my 5010 and love them, I went from a mk1 solo (with Hope tech enduro) to a 2016 5010 with these wheels, same forks and other gear. The real world differences are night and day. The weight saving plays a factor though it is not a huge saving 200gms across the set.
The real difference is the stiffness in cornering – imagine driving a standard car and then a car with uprated and lowered springs, it feels incredibly direct and seems to fire out of corners much quicker, if you are on it.
It will depend on the trails you ride and what kind of a rider you are, of course, but in terms of ride feel they are the single best upgrade I have ever made (tubeless and dropper posts up there too).
The interview with Graham from sixth element hit the nail on the head, it is all about the stiffness – that is where the benefit comes.
If you are bashing fire roads, just riding along or ride wide open plains then the benefits are reduced, because a light weight set of alloy rims will be better. But if you ride a lot of tight corners, single track etc then I really think you will notice the difference because handling becomes much more important than just weight and comfort.
With reference to Hob Nob’s post: –
Unreliable – not yet, been riding them for a month and all good so far, lots of drops, roots and jumps but no rock gardens (yet)
Expensive – yep
Negative ride characteristics – not for my riding
Love them..!
