  1. So as you can see on the very smallest cogs there is this slight slight bend. should i pass this off or drop a link. 

  2. Leave it. You’re not supposed to ride in either of those combos therefore it’s fine.

  3. You should not be using those combinations in real life. As it is, if you accidentally do shift into big-big, you are cool. On my touring bike if I try to go big-big, It jams and takes some work to get it off that combo. What you have now is perfect.

    Your smallest chainring should not be combined with your smallest rear cog. That is cross chaining. So, to answer your question, leave it and learn chainring and rear cassette gear discipline.

  5. You should learn about gear ratios, then work out which ratios you have. You would then understand .

    Any reason not to have the wheel all the way into the dropouts? You could put it back a quarter inch and make the whole thing slightly more optimal.

    Holy fuck some of these comments are so dumb.

    Obviously OP is not going to ride in these gear combinations. When sizing a chain you need to make sure big/big won’t explode titre derailleur and small/small doesn’t rub on itself.

    OP: you’re good.

  8. I have a 3×7 speed cheap bike. I studied the best gear combination to keep the chain as less as possible bent, this causing a premature wear of chain, rear sprockets and chain rings. I will say F for front speed and R for rear speed. I recommend this combinationsof speed marks on your shifters: 1F-1R/2R/3R when climbing steep ramps. Then go to 2F-3R/4R/5R. Then go to 3F-5R/6R/7R. If you turn upside down the bike and look along the chain line you will see the best alignment with straight chain on 1F-1R, 2F-4R, 3F-5R. Never use big-big or small-small like you did it.

  9. Chain is good.

    Make sure you slide your wheel all the way back into the dropouts it looks forward here
