Workswell WCB-M-062 manufacture failure
« on: July 05, 2017, 06:53:19 AM »

Finally have some time to post this problem. I make long story short.
Ordered wcb-m-062 21" frame, headsets 2x, dropouts 2x, seatpost 400 and bb - everything was nice packed and came quickly.
Assembling the bike - was easy - except seatpost! I haven't take out my torque wrench yet, I already heard a tiny crack sound  :o
This what happened

I was thinking "OK, maybe I overnighted the clamp"  but this time I ordered seatpost from Peter (30 days waiting) - assembled this time with torque wrench.... and.... and... on 2nm I heard a similar crack sound again....

Contacting Peter again and asked about seatpost clamp torque values - same as others.. starting from 3nm.
I don't know can you see on the pictures, but these are not cracks.... it's more like cuts...
Starting to inspect the frame and find this
the inner frame was very sharp and the shape is like a pliers - just a tiny torque acting like cutting in.
So.. I file this sharp edges off.... ordered new seatpost again! :) and the grass is green and sky is blue, everything is OK now and bike hitting xc marathons several months.

Contacted the workswell company seller and told them everything.... the only thing they said is "You overtightened the clamp."
sorry about bad english..

I have a 062 (an early one) and I tighten my bolt to 5nm. I'm using a Syntace P6 HiFlex post. Tightening to 5nm should not crush the seatpost.

A least it seems like you sorted the problem. :)

Thnx for reply.
Yes I sorted it out by file this edges off - I cut my broken seatposts (cut out the broken parts) and trying to torque good parts again with 6nm and it was OK.
My concern is that if You have any warranty issues with this company - so... You are on your own.   :(

Use carbon paste and 4 nm should be enough. When carbon parts are involved, I don't use more than 4 nm.
