Pardon my ignorance but wouldn't it be better to have a dirty chain that could be cleaned / re-lubed easily rather than a cleanish chain that is hard to clean due to the chain choobz..
Clelands are designed for use in extremely muddy conditions where mud is scraped off the tyre by the chain or large clumps of mud can fall onto the chain from above.
I have seen unprotected bikes with so much mud on the freewheel that the chain couldn't find the cogs beneath.
We used to fit aluminum plates between the tyre and chain but this a lightweight alternative. Chain choobz can be made so they can be easily removed. On the Cleland NRS they are not closed tubes but spiral strips that wrap around the chain. The chain requires cleaning far less frequently, especially if the front mudguard and mud flap are both effective. I am intending to make some square spiral chain choobz that will be narrower and neater and even easier to remove.
Re suspension types. Without disusing the relative merits of various suspension systems, this bike uses the Non Resonance System (NRS) developed by Renault Sport.
The chain tension combined with preloaded springs completely stops the suspension from bobbing. The preloaded springs keep the bottom bracket high and also allows the bike to be lifted and hopped like an unsprung trials bike.
In practice this means that the NRS behaves like an unsprung bike with the suspension only moving when the bike hits a bump. The lack of negative travel means that all the positive suspension travel can be used before the suspension bottoms. And the system also works well with the low pressure tyres ability to absorb high frequency vibration.
