comment How to achieve an always clean chain
i think degreaser that does not advertise as bio degradable is already idiotic. kerosene and gasoline is even worse. if you can't clean with water and soap, just throw it away and buy another. steel is biodegradable :) also, your goal is to get oil INSIDE the rings. and degrade will ALWAYS remove that. and putting it inside again will be much harder.

comment Can I use a Presta tube in a Schrader rim?
imho, MTB rims with presta valves plus the grommet are the best of both world. you will never get a flat because of valve steam pinching.

comment how to use “smart valve” pumps?
i will, and all my spare tubes are presta. but there is no reason to trhow away a perfectly good scheader tube just because it is annoying to pump :) so i'm running with both for now, until i get a flat.

comment how to use “smart valve” pumps?
yep. the unmounted tube did the trick. i measured how deep it has to go (almost the entire thread have to disappear) and then it can fill the tire. it was more trouble than it was worth it to try to insert it on the empty tire since it has MTB rubber... i just pumped a little with my hand pump.. debating if i will keep this floor pump or return it. it seems practical but i leave my tires empty pretty often. maybe it is a good motivator to not to :)

"Press the Clever Head on to the Presta or Schrader valve stem as far as it will go" hum. maybe because my Schrader tire is completely flat i can't press it enough for it to "work"?

comment Which rim tape for 700x28 tires?
ok, i looked to buy those... there are a million types and i have no idea which one i need before I take my tire out :( and i only want to do that when i'm ready to put it back on and not remove it until the next flat :) will use tape this time and see if i remember to take notes for the future. thanks

comment Which rim tape for 700x28 tires?
i know all that :) just want to know if a tape width of 17mm on a rim that i can measure the outside as over 23mm will be too thin and move around exposing a nibble or not... don't want to 1. remove tire. 2. buy tape. 3. measure and see it is not a good fit.

Nice! never heard of those before... but don't see how they protect around the steam (not that tape does a great job there either)

comment derailleur P-screw/B-screw does absolutely nothing
very good point! I did not check the spring strenght when i renewd the derailleur. I am using it as is and set it up so that it only grinds in the very lowest combinations (which i rarely use for my comute).. but as soon as i have to open it up again for lube/mud removal, i will surelly check it up and update here if that was the case.

comment attaching seatpost acessories to rear of racks?
The light i have looks like it is planet bike, but it is not. it is just 1mm too deep and 0.5mm too thin. damn china.

after trying both options from Daniel i'm now considering 3d printing... :/ sucks that there are no standards for those things. Damn all those companies.

comment derailleur P-screw/B-screw does absolutely nothing
@joseph_morris ok, came back at this, again :) last time i adjusted the H and L screws as best as I could. and really, the cogs only grind now when using lowest in front and lowest in back. so i was avoiding this [in the 2 times i was able to ride since then :(] and well, the b-screw is still screwing me. everything seems perfect, but it does nothing. it sits in the correct place on the frame just fine. I think i will have to open the derailleur... but i think for the trouble, i might get a new one... well, i will just avoid the climbs for now :)

eek! i'd avoid having a shifter lever right where i'd grip to break in a panic. I pass.

@DanielRHicks see the second paragraph here parktool.com/blog/repair-help/… " If the pulley is rubbing against this cog, tighten the B-screw to increase upper pivot spring tension, which pulls the pulley back and away from the cog" what happens in my case, is, no matter what i do with the B-screw, the distance from the pulley and lowest cog remains the same. the arm never moves when i change the B-screw.

comment derailleur P-screw/B-screw does absolutely nothing
@DanielRHicks they run with only the chain links separating them. The noise cames from the chain axis passing between. It is very possible, hence the Raison d'être of the B/P-Screw. It is there just to adjust the guide being closer to the gear but not touching. Also, i am starting to think it does not matter much. I will only have low gear front and rear when i'm pedaling as slow as possible anyway... don't think anything bad will happen if i leave as is....

@DanielRHicks the guide gear on the derailleur arm grinding on the low gear of the freehweel. almost like the picture. it makes a loud clicking noise that i don't hear on higher gears.

@DanielRHicks i opened the whole thing, removed all springs, scrubbed a little superficial rust layer from the inner parts and removed the clogged up old grease, packed everything back with parktool grease that was within shimano spec. THe main spring that is what the P/B-screw affect has no way to be put in wrong, i guess...
