the only part that appears "low quality" are the bearings its being mentioned before but I will certainly be ordering a different set of bearings.
As you can see below there are red m3 countersunk washers, these were £4.50 for 20 on ebay and match the red/black/white theme im going for.
serpents pack of 20 costs £18....no brainer really.
There is nothing binding or catching the rear moves effortlessly and doesnt grab at any point. the turnbuckles are a doddle to measure up so long as you have an measuring gauge.
Adjusting the rear wing takes about 30 seconds with just two screws and move it to the other hole.
A couple of the longer screws took some effort to get in there, I was almost needing a 2mm tip
Another plus ive noticed are all the boots are included all round and a 16t pinion also included.
the rear end complete....
