Hate that 'Raaaaaaaaaaatcch' noise when you operate your roller blinds?

Well live in peace and tranquil quiet my friends with Dr Beebenson's patent-pending EzySpin Chainrollerᵀᴹ chain guides!

Truth be told I just chopped up the existing plastic lower guide, turned it upside down and added a sliding door roller. If you're going to give it a shot (and please do, the silence is frankly blissful!), please note I've actually 'faked' this shot to make the chain look a bit tighter around the pulley wheel and more logical for the picture. Make it that tight in reality and you'll be dragging your knuckles (no, not like that...) up the window frame.

That's one less OCD twitch left to bug me at home!
Upgrade time! Don't see why it wouldn't work equally well for blinds

Missing some spacers from your M8120 cranks?

In my case it's matchy-matchy and everything. :p

The spacers are 1.5mm thick each, but there is a bit of free-play around the cranks as the ID is -25mm, so the spacers do need to be preloaded very lightly then tapped about so they're concentric - but they just clear the outer race of the BB and are the perfect thickness. Even the stock Shimano "safety tab" dropped into place like normal. :)

So matchy I didn't notice!
