Excellent service and an excellent product
fitted straight on, nice feel of quality. Easy set up
Nicely made, easy to fit, works very well, could be a touch lighter but thats me being fussy
Little clunky but does what it needs to do.
Awesome
As Above
Very cheap and does as it should,
I have used planet x a few times now, great service and fast delivery. Very happy.
single speed kit that is nice looking with a couple of cogs and all you need for converting your rear wheel to single speed. the cogs are tought but a bit weighty.
Royal mail delivery was slow, service under the average and not satisfactory
Just lob it on and Bob's your mothers brother, works a treat!
I have ordered from Planet X a number of times now and the service is always great, texts when bits are dispatched and arrive, and always quick despatch times.
Does what it says on the tin!!
Solidly made and simple to install.Nothing to go wrong in my opinion.
Quick and efficient service.
I have never fitted one of these before and it was easy enough. Some simple instructions wouldnt go ammiss though.
Excellent
Looks well made and easy to fit to bike. I have not managed to connect the chain yet as I snapped a tendon in my finger removing the cassette from the rear wheel! I am sure it will work fine.
Quick delivery.
Great stuff, no complaints.
