I thought this may be the high pivot frame, but I dont think it is. Similar.

this is wissco frame

Hi everyone, I've just ordered the steel version, on which I plan to build a bike mainly focused on bike park riding. I'd really appreciate any feedback if someone already has experience with it.

I'm mainly wondering about the rear shock and the optimal travel for this frame. On the website, I only saw a photo of the frame showing a 210x55 shock mount. Could anyone confirm that?

Not sure if anyone else has it yet. Very interested in hearing your impressions of it, though.

Thanks for the reply. I have to admit, this will be a total experiment, as I'm planning to build this frame as a single speed bikepark setup with 27.5" wheels.
I've been riding for over 20 years and have quite a lot of experience, but I've never decided to try something this crazy before.

Still waiting for mine to arrive, but everything I've seen says it takes a 210x55 shock.

I think the BB will be very low as a full 27.5, but maybe it's not a concern for park riding.

I plan to eventually set mine up as a mullet with a +1° angle set and a 150mm fork. In that configuration the BB height will be comparable to similar travel bikes from, e.g. transition (with the flip chip in low), and the HTA will be around 64-64.5°

You have a very good idea with changing the head angle using anglesets, and I'm planning to do exactly the same. As for the bottom bracket height, I don't have any particular concerns because I want to use very short cranks, 145 mm. The only thing I'm wondering about is whether it's possible to achieve 160 mm of rear travel and 170 mm at the front, so as not to mess up the geometry and to make sure everything works properly.

They are currently working on a gearbox version of the high pivot frame. Chinese Gearbox would be pretty sick?

A gearbox version? Now that is interesting!

My frame finally arrived. It was well packed, and the overall quality makes a very good first impression.

Sweet! Mines waiting for me when I get back to NZ.

What size frame did you get and what's the seatpost insertion depth?

Cheers!

Can't wait to hear impressions on the build and especially on how it rides!

North American source if anyone is interested.

Since this is a 100% custom project, I decided to make a few modifications to the frame. The frame has been completely sandblasted, and some of the components have been satin-finished. I also decided to weld additional reinforcements around the head tube area.
At this point, I'm just about to have the frame painted and assemble the entire bike, as I already have all the parts available.
As for the seatpost insertion depth, it is 117.5 cm

not sure what to make of the 117.5cm insertion depth

If you disassembled the frame, what do you think of the hardware? bolts bearings etc. all good?
