In Dorenaz (CH), to go to the top of the mountain you must take a cable car for 5 min and the bike is upside down ... and then you ride a downhill trail where you need to brake really hard sometimes ... but I never have had a problem. Why? Because if you have bled your brakes well when you service them there should be no air in the system :)

It is hard to give you the exact reasons why this is happening, but your derailleur body lost a good mechanic connection with the cage. Maybe the screw that holds them has just became loose, or maybe it has gone bad, or maybe your derailleur is just old. Hard to tell from the pictures. I don't want to be pessimistic, but repair will be hard, as manuals and ...

Decades of experimenting and I still am a sucker for the 'next great thing.' A few tidbits I do trust, now: Tiprep antiseize for every bike part that is tightly pressed/bolted infrequently, especially dissimilar metals where galvanic corrosion will occur; Ti's bad, but Alu to Alu or steel/Ti may be even worse. Greases are NOT antiseize, nor is it a ...

This from an old article circa 1996 it references a Medai floor pump. "Screwed into the base near the compression tube is an air tight steel chamber. This chamber is known as a reservoir and holds a volume of the compressed air to assist in equalizing the pressure of the pumps compression chamber and the inner tube. This feature gives the tire a small assist ...

Before you buy anything,make sure the shifter is adjusted corectly. Put the bike on a stand or whatever it takes to allow the pedals and the rear wheel to move freely. The adjustment should be made from the second highest gear (the second smallest Which is the second from the outside). Tighten the adjuster until the chain makes noise trying to shift into the ...

Shimano warrants to the original retail purchaser that the Shimano bicycle division product for which they received this warranty, is free from non-conformities in material and workmanship for a period of two years (...) As you can read in Shimano's North America homepage. So if you bought this new, go there and complain. Disc brakes with proper ...

You choose a non-trivial project. Lots of good tips have been given, but I must warn you: restoring an old bike is not a to-do list like I have seen here. It's not like maintaining a new one. There are all sorts of difficulties with old, seized components, that will be a pain to unmount, and which will require a careful evaluation before rebuilding. If you ...

A couple of things could be the reason of your derailleur shifting on its own. I assume that both the derailleurs and the shifters are in good working order, that you washed and lubricated them and correct adjust them with the respective screws. Please refer to Park Tools repair help guide to correctly set all these adjustments. You can find it here and ...

It depends on your objective. Are you doing it to save money, or because you want to ride this bike? You can do it, but unless you are attached to the bike there may be a better option. My wife and I got back into riding last year, dusted off our late 70's ten speeds (2 by 5, not 10 at the rear), got a tuneup from the local bike shop including new brake ...

It's doable although it doesn't make sense from a cost perspective. Only do it if you have an emotional investment in the bike or want a fun project that will teach you a lot about bike mechanics. To give you an idea, I bought a 1975 Peugeot UO18 Mixte (a woman's road bike, perhaps similar to your mom's) that had been stored in a barn and turned it into my ...

This is not really an answer, but it's too long for comments. @Daniel has given some good starting points. For a bike of the vintage, Richard's Bicycle Book by Richard Ballantine would be a good bet, and is available second hand. When you say rusty, do you mean the frame, or wheels, handlebars, brakes, pedals, etc? The way to approach such a project ...

You've chosen a non-trivial project. If the bike has been unmaintained since the 70s it's got several things wrong with it from the git-go: The tires are rotten The brake blocks have hardened into concrete The grease in the bearings has dried up Further, finding parts for a bike of this age can be a challenge. But if you really want to learn how to ...

Ghost shifting is generally caused by the frame flexing, not by friction in the cables. Other causes can be a poorly fitting or too short cable housing. Something is causing the length of the cable between the stops to change. Cleaning the cable run and using a teflon coated shift cable won't hurt and might alleviate the problem if it's a combo of bottom ...

First note that if you get full movement in your rear gear shift you will probably have all the range you need. I think this would be EASIER than working on front derailleur. SO I recommend working on your Secondary Problem first! :-) NOTE: Allow plenty of time for fiddling with your gears. Do it in a warm dry place when you have time so you can learn how ...

Epic Bleed Solution did an amazing post explaining the details of hydraulic disc brakes, covering concepts and mechanic principles, different fluids, pads, rotors, etc. It's a very good introduction to hydraulic disc brakes that you can find here: http://www.epicbleedsolutions.com/blog/how-hydraulic-brakes-work/

It could just be bad luck. Or, there may be a piece of glass, a tack/nail, or caltrop stuck in your tire in a way that wasn't visible to the shop that replaced your inner tube. It may be deeply embedded in the rubber tread, invisible on both sides, and only pierce the inner tube when under both air pressure and the weight of a rider. When you or the shop ...

New 105 5800 crankset is compatible with older components, according to numerous posts in this thread. Yes, you can use the same cassette. Even if you use short cage rear derailleur now, it should have enough capacity for 28 teeth sprocket. 11 speed Shimano chains have the same internal width, so these should be compatible with older 10 speed systems. ...
