Typically, a chain uses a grease lubricant which is applied hot to the chain into every crevase of the chain before the chain is assembled. Its generally the best lube you can get on a chain, but its impossible to apply at home in the same way (contrary to sheldon brown) [aside from the fact that that particular formula is likely not sold]. Some more details ...

If you can pull the lever all the way to the handlebar while not getting much braking force, then it is very likely that you somehow got air into the system somewhere, and you need to bleed the entire brake system. Perhaps when you were changing the pads, you pulled the brake lever while the pads were removed, which would allow the pistons to come out too ...

I remember doing this last year. You need a way to keep the spring-loaded part (on the left in your pictures) out of the way while you move the other part into the correct position where you can attach the screw. If I remember correctly, I did this by sticking a long screwdriver between the axle and the spring-loaded part and holding it with one hand while ...

My experience is to use spray teflon. Nothing else works for very long. Most oil based lubes dry out and get gummy. That is what stops it from working. The little parts get gummed up and stick. Use teflon spray and flush it out well. Hold the brake lever open with a rag under the shifter to catch the excess and spray into every opening. Let it sit for a ...

These are just old U-Brakes (installed at the chain stays as was cool for part of the late 80s). You just need to unbolt them from the studs (maybe hit it with some penetrating oil to help loosen it oFF the studs). Unfortunately due to the placement of the U brake , you're going to need to get another u brake since you won't be able to mount a normal brake ...

Since nobody so far has posted weights, I'll leave "one" data in case it's useful for somebody. | 105 5800 | Sora 3500 | -------------------+----------+-----------+ Levers | 486g | 496g | Brakes | 388g | 357g | Front Derailleur | 89g | 105g | Rear Derailleur | 234g | 246g | ...

Beyond a weight - you also need to look at Number of gears, Under tape cable routing, Stiffer cranks, Dual Pivot SLR braking, Aesthetics, Performance (slicker shifting for starters).

Parts need a break in time to stretch, flex, and do what they do before they kind of settle in. When I worked at a bikeshop, we told our customers to come in after a month or 2 so that we could go through and get everything tuned up to where it should be after the break in period. Not only is your situation normal, most bike shops WANT you to bring it back ...

Yes, 8/9/10/11 cassettes have different cog spacing. You have several options: Replace freehub body to Shimano/SRAM 11 speed compatible, if hub manufacturer provides such an option. It's 1.85mm longer than 8/9/10. Replace freehub body with Campagnolo one. The trick is that all 11 speed cassettes are cross compatible, but Campy freehub body has same width ...

As you're not clear on road vs mtb, there's two answers. For 11 spd road drivetrains Shimano uses a 1.85mm wider hub with the drive side flange closer to the centerline to compensate for the additional width. Using a spacer allows the wheel to be backwards compatible to fit a 10 spd cassette. You can't fit a 11spd freehub in place of a 10spd freehub unless ...

Shimano/SRAM 11 speed cassettes are wider than 8/9/10 speed ones. So yes, you need a new, wider freehub body, unless your old one was not very old and used a spacer to fit a 10-speed cassette. People with non-Shimano brand hubs are less likely to find replacement freehub bodies, it seems, leading to replacement of the whole hub, or even the whole wheel if ...

In addition to the points noted in other answers, there is a significant technical difference: bearings. Traditionally, Dura-Ace equipment with bearings has had much better quality bearings/races/cups/seals/etc. That appears to be true here as well. Look at the parts breakdown documents from shimano and you'll see a significant difference in the ...
