I would just cancel and get a SRAM cassette...

Yes, I would also think the chain is included... So they only want to send the cassette for the listed price?

I ordered a ton of stuff the last few days. I decided to build a XC hardtail and ordered nearly all the parts off Ali except for the derailleur, cassette and chain (is gonna be Sram GX), the brakes (propably Deore) and the fork.

I ordered a OG Evkin CF-052 frame. It seems to be the last one in 17" they had. They told me they stopped production.

They have good reviews, so I hope they are OK I have built a wheelset with comparable rims but 28x28mm size and they are holding up great (1 year in use now).

There has been already a delay with the shipping of the rims. They say they do not have the 24h in stock and have to make them first. 2 week delay... Communication is OK.

Seems like the only brand more or less with consist positive reviews is the Sigeyi.

Indeed, that is what I also found when searching for a cheap power meter.

cycling100.com has them the cheapest I could find, but the store gets bad reviews, so I did nog order them yet...

There will be sales on Aliexpress starting tomorrow. Elitewheels normally has some promo's, but don't expect too much

You should be able to find sensah parts cheaper from tomorrow. There is also 5 USD off for every 30 USD spent (max 15 usd) so that will give some extra savings.

So yesterday the BR-05 brakes arrived and they look like indeed a step up from the old ones. The "lever" is longer, so i guess there is more force on the cilinder. Another great thing is the construction and setup is different which make for a better fitting of the calliper in my small size 52 rear triangle. I was fearing the slightly bigger new calliper would not fit, since the ZTTo once only barely fit, but the lever of the new calliper falls on the inside of the frame so the small angle of the rear triangle is no longer a problem.

I only tried the brakes on my driveway and the front one already seems a lot better than the ZTTO one...

I managed to f*ck up the rear brake by contaminating it with oil so I can't comment on that one. I was trying to get some (...a lot) of oil in the cable housing of the rear brake because the movement between cable and housing seemed rough and I guess it must have gotten on the calliper and pads... Turns out my rear brake cable was also worn where it enters the frame in the front, so I immediately ordered a compression-less Jagwire brake-cable set (the old was not compression-less) I am going to install in the next days. I will keep you updated...

pictures of these particular cassettes?

Do you mean pictures of my cassettes specifically or this type of cassette ?
