Hi,

I’m looking for a book/author. It had the catchphrase ”who is the dark afraid of?” on the back. About a secret society of warriors/knights who fight off dark forces who appear on Earth now and then. The members of the society have supernatural powers to help them, but everytime they use these forces they get a black scar. The scarring will eventually consume and kill them. The target audience for the book are older kids/teens.

Does anyone recognize this?

I'm tinkering with a welded steel frame beater bike which has an undersize seat post and a home-made thick copper shim.

I'd like to replace these with a correctly sized seat post instead.

Trouble is, the shim is glued in, so I just can't pop it out and measure the I.D. of the seat tube.

I'm confident I can eventually remove the shim and clean out the seat post, but to limit the bike's down time I'd like to have the replacement part already available when I start that work.

Seat tube outer diameter looks to be 25.0 mm by Vernier caliper. Based on this, is it possible to say which diameter seat post the bike would need?
