Answering your cycling questions

I'm assuming by 'the big long one' you mean the internal spacer?
This slides over the spindle inside the BB shell, between the bearings, to stop the bearings moving when you tighten the crank bolts.

The conventional method of removal for mid bb's is (though not fully recommended) usually a hammer and a screwdriver in the axle hole. However fitting the new one can be more problematic. The old bmxer trick of a hammer and a lump of wood can cause no end of problems with fitting the bearings straight - all I can really recommend is either using the correct BB compression tool, or if you don't have access to one, book it in with one of our workshops.

Hi, guide as follows:

Weight: to fit 19mm spindle: 137g (4.83oz : 0.30lbs)

hope this helps.

there is acouple of things you need to check 1. does your frame have a mid bottom bracket?

2. If your frame does have a mid bottom bracket and its unsealed then in side the bottom bracket shell you need a lip to hold the sealed bearings in place. If you are unsure then please take it in to one of our shops

it depends on weather your frame has a mid bottom bracket and if your cranks have 19mm axle, i think with gusset cranks are 20mm axle

Yes this bottom bracket will fit the We the people justice frame.

this will fit fine, you need to make sure that the crank you have, have got a 19mm axle.
