chain too short and jumping when on easiest gear?

I felt pretty smooth yesterday lol. Always in my hardest gear. Chain being too short seems possible. I have no idea how to tell if my chain is the proper length.

I'm planning to buy a Box One DH tranny kit and it comes with a 7 speed 11-24 cassette, i currently have a 38T chainring and would like to run a smaller one like a 34T but don't want to overdo it because i don't want to spin out during really fast sections where i want to build up more speed, should i run a 36T or 34T?

Running a 34t will move you down your cassette one or two cogs. With only having 7 cogs that makes sense. Unless you find yourself running out of gear on the low end. Try it.

what's the average bike shop price charge for a 26" 32H wheel lacing? I want to know what to expect once i get the hubs from the mail.

Thanks.

Depends on spokes but I would hope no more than $150.

150? Woah, I need to get into the wheel building business

Just got a new wheel built a couple weeks ago.
$114 labor and spokes.

Anyone here know anything about the Bos Idylle rare? The manual says that it requires a minimum of 155 psi (i'm 52kgs or 114lb) and when i pump it to just 80 it's almost impossible to compress

You should cycle the fork up and down whilst pumping up or the negative chamber doesn't fill

I did and the fork feels very nice at 80psi now, but not sure why the manual says 155psi.
