Without fail all the braaap bike threads there's always negative comments , but you don't see negative posts about ycf's.
I won't bother reading another post about braaap bikes because they always end up being a flame fest. No linkage blah blah blah
if you want to check how long the rear shock should be , here's an easy quick way to check , but it sounds like you made up your mind about the bike early on.
My bike came with a 280mm shock and handled like a pig , after I measured it the bike actually needed a 260mm shock. , now it handles great.
Not all bikes come with the right length rear shock so it's a good thing to double check
This is the easiest way to measure the length rear shock you need
Download a protractor app onto your phone
Get some packers to pack under the wheels when they are needed , a couple of pieces of timber about 150mm long & about 10 to 20mm thick
Stand the bike on a bike stand
Take the rear shock out
Place your phone on the lower part of the fork leg (stanchion) and read how many degrees the fork angle is with the protractor app
You want to be around 26 degrees , I wouldn't go any less than that , so 27 is fine aswell
To get your fork angle to the correct degree place packers under the front wheel & keep checking until you get the fork angle to 26 degrees or 27
Once the fork angle is correct , measure the thickness of packers you placed under the front wheel
Now place the same amount of thickness under the rear wheel
Measure the eye to eye length where the rear shock bolts in
This measurement is how long the rear shock should be
