Terrible and Frustrating Experience
I wouldn't recommend Winstanleys. I ordered a complete gravel bike which should have been inspected and built correctly. The bike came quickly which I was happy with but it wasn't built properly and unsafe to ride. The brakes were setup terribly and could hardly stop due to the bend in the cables and poor alignment. The chain wasn't sized so the shifting did not work.
The worse part is removing the cranks, I called and asked if they greased the spindle of the BB which they said some of their mechanics don't due to a difference in opinions. Unfortunately, this one wasn't and was torqued really tight, they might as well have welded the cranks to the spindle. An independent bike shop had to cut off the spindle to remove the cranks the BB.
If you're after a bike that's safe to right from the box, or aren't willing to take it all apart to ensure it's properly built then I would advise to spend your money elsewhere.
Pros - attractive price but you will likely have to pay a lot more due to the poor assembly job. Guy on the phone was nice enough.
Cons - terribly quality and response time on email.
