    AGAIN, if you have to buy a new chain, a derailleur and a new freewheel, and possibly a new shift cable (the end of the old one is badly frayed) it will cost you more money than the bike is worth....
  2. I should have been more clear. A new chain will...

    I should have been more clear. A new chain will often skip on old rear cogs due to the cogs being worn, especially if the small ones were ridden more. That would require a new freewheel (requires a...

    OK, I understand the challenge, as I had to learn some Italian for a trip to Italy a few years ago, and I won't even attempt my 50 year old French, but please at least construct sentences with...

    I've always felt that videos are a good supplement but a poor way to learn proper procedure. It's just too easy to leave out important details. I recommend two strategies for you.

    Not more precise, as one has to spread beyond the needed spacing and then check/recheck. It is safer, as some might beef on a lever too much and cause problems. Personally before we got a Park tool I...

    Actually weight has an effect both when lifting (climbing) and when accelerating, but again the effect of 3 lbs is minor. Remember that inertia is one of many factors, including friction, rolling...

    Its not bearing grease. It's to be expected that a higher gear (52/15) will accelerate slower than a lower one (50/17). You have more leverage in a lower gear. The latter is 15% lower gear.bo

    I don't know of any product that would hold up under such conditions. New hub time, in my opinion.

    Yes, needs to be adjusted. Large/small is not cross chaining, so that's not the problem. I would note that the highest gear is one you should not be riding often - harder on the drive train and less...

    We need to know if it rubs constantly in the highest gear or if it occurs only during part of the rotation. Two entirely different problems and solutions.

    Also need to know what you meant by "When...

    The least expensive way to convert from downtube to brifters is often to sell the DT bike and buy a brifter bike.

    You folks must have a lot of time on your hands. Either that or you have some Don Quixote blood in your veins. The OP obviously is not interested in anything but a spoon-fed solution, yet is...

    Additional advice: DO NOT make your first attempt at bike mechanics building a bike from the frame up. In addition to the considerable expense compared to buying a working bike, there are a multitude...

    The hex bolt has a collar that is underneath the outer ring. When you unscrew the hex bolt the collar pushes against the underside of the ring to pull off the crank. Therefore you should not remove...

    You will sacrifice zero high end speed by going with a 12 tooth rather than 11. Keep in mind that for decades racers of all calibers had 52/14 as a high gear. 50/11 is over 20% above that, and few of...

    You don't know how fortunate you are that you received assistance in spite of your lack of effort in helping, and your lack of any apology for making helping your more difficult.

    A q/r should have a slight amount of play when not mounted, so they are adjusted too tight- which is typical of new hubs. Some also have too little or too light grease and allow the balls to rattle...

    YES - you are making a big deal out of nothing as far as component difference is concerned, and there is no way that component quality/weight can make up for the huge loss of low end gearing.
