Helpful and informed staff
To replace the front headset on my otherwise excellent 'Bullitt' Cargo bike. Had a smoothie regular on a couple of other bokes and they are hard-wearing, superbly sealed and up for regular exposure to all the grit and salt on the winter roads here.
I've ordered a great deal from PX / On One over the last 10 years or so - 2 bikes, 2 'frame only' and a number of odds and sods to build / rebuild the frames. Delivery to Denmark is quick, reasonably priced and I've never yet had a duff order.
fitting was a bit of a hassle, as the lower bearing did not "click in" once pressed onto the bike. Solved by riding the bike and making one decent stop, as that provided enough force to make it click. It was then very easy to properly modify the headset.
Excellent. 2 days from order to door - standard post!
Not as smooth as a hope headset, but for 20 quid, excellent. Interested to see how it lasts over the winter on the muddy commute to work.
Recommended the wrong headset by Planet X staff and sent the wrong colour.
