Epic Evo Clone

[akuutti247]

I have lost faith in Epic Clone(s bottom bracket area). I don´t want to experience same kind of situation as last summer when the long distance light bike was useless for three months..

I couldn´t resist the temptatation and contacted Hongfu. My e-mail blocked their message but they didn´t give up and used WhatsApp instead. First I thought it was an asian romance scam  , but then realized it was from Hongfu..

Hongfus customer service beats Airwolf 6-0..

FM138 frame came yesterday. It was 1950 grams without axle and shock bolts (with UDH). It feels more robust and has true 120 mm rear suspension..

What is the cost of hongfu?

I found that the rear shock bolts on Epic clone are not the most durable hardware. Ordered these for the linkage when the bolt broke:

The rear shock linkage, where it connects to the rear triangle in two places, has bushings in it with poly flanges.  However, I've noticed the way they sit against the CF frame causes significant resistance unless you run the bolts so loose that there is play and they risk backing out.  Not great for small bump compliance at the recommended torque spec.  The backing out of screws is easily fixed with red loctite, but you are still fighting the battle of play in the linkage vs too much resistance on the bushings.  Seems a relatively straightforward okayish fix with some greased M8x16 shims, but definitely an oversight on the design.

Will follow up with pics and my solution in a few days if I'm happy with the shims.

Also for those who said 2.5mm shim under the headset cap, I've 3d printed a few at different thicknesses and found 3.5mm to be a better fit.  At 2.5mm, it crushes the rubber gasket in the headset cap a little more than necessary for sealing.

Also, my recently purchased frame has a rubber gasket for the brake/RD lines at the bottom bracket/lower rear triangle junction, so it seems they are still improving things.  I do wish the seatpost could be inserted further, but given the role of the frame I can live with it.

They still don't have a gasket for where the Brake/RD cables enter near the headtube, but I'll probably print a solution for that too once my roll of TPU filament arrives.

This part you are wishing for… it can be bought from most
bike shops. It is the MY21 Epic headtube port grommet. I added it to mine!

How did the shims work out for you? I haven’t noticed this issue with my build, as the small bump compliance is pretty good. But would def add them when i build it up with the new front triangle.

Ty for the heads up on the headtube port grommet.

The shims definitely improved the stiction of that linkage a bit.  I ordered these: https://www.amazon.com/dp/B0BT5S3TYY
 I used the 0.2mm (4 total, one on each side of the bushing with plastic on it), though individual frame tolerances may affect which thickness is best.
