check everything that has human contact because there is a force exerted on all thes eparts when stomping on pedals


pedals, cranks, BB, chain, cassette, spokes
the seat post and seat rails
bars and the stem connection


Also check the frame for cracks, especially if it is a full suspension bike.  when stomping on the pedal you may be exercising a small crack in the frame that is pinging -- check all the welds first - particularly round the BB area.

It might be worth saying which bike frame it is and see whether it has a history of cracks.

Why does my bike make a noise when I pedal hard?
I'm looking for a 100% rye pizza base recipe. The recipes I can find all combine the rye with other flours (typically wheat based). I know it is possible to create 100% rye based pizza bases as I know of one pizza place in town that sells them. 

I understand that they had to do something special to keep the pizza base from falling apart. I don't mind experimenting a bit to find a recipe that works, but I could use some ideas on where to start - what sort of ingredients might bind the rye so that it doesn't crumble as a thin pizza base and maintains a low glycemic index for my diabetic wife.

The only dietary requirements would be that the various ingredients maintain a low glycemic index or a specific ingredient with a high glycemic index can be counteracted by some other ingredient. And only using rye flour.
