2pcs Bicycle Chain Tensioner Adjuster Aluminum Alloy Chain Fastener for BMX Fixie Bike Single Speed Bicycle, Red

Very nice parts good value for money great colour

The tensioners are too wide and stop the wheel being tightened within the dropouts, making these useless. Look nice but not suitable for the job on my bike.

I haven't touched these yet but I know it will do its job but now the bike I was going to put them on I do not have so it's probably the later project

Don't work that well on my track bike.

These things came with 3 different sized bolts, for a universal fit and didn't fit my standard BMX bike.

It went on okay but after a few minutes riding the force on the tiny bolt on the drive side was too much and it just disintegrated and came out somewhere on the road. I realised this was because the spacer between the end cap and the lug is too wide so it’s never tight on the dropout. It was cheap so it’s what it is but I almost destroyed the chain and wheel because of this.

Don buy these tensioners! Mine snapped off within seconds of riding!
