Put link into chain, hold chain on either side, use thumbs to hold snaplock over link. Gently pull chain using thumbs as fulcrums...this will put pressure on the pins forcing them just a tiny bit inward. Snaplock should slide over. (Think of it kind of like bending but not breaking a pencil...both hands on pencil (chain), thumbs next to each other, gentle ...

It's much better to open the chain. Derailleurs are not really designed to be opened repeatedly, and doing so inexpertly can potentially ruin the derailleur. Chains might have either a lock link or a master link of some kind, find that open the chain and then thread the chain through the derailleur. If the chain does not have one of these links, you will ...

SRAM GXP bottom brackets can be user serviced, but it is usually unnecessary.
To service your BB bearings, first remove the crank arms. Then place your thumb in the BB spindle hole, and bend the joint enough that your knuckle makes firm contact around the entire ring surface of the spindle hole. Pull outward using fairly firm pressure, and if necessary, ...

It is almost impossible to rebuild a wheel (i.e., new hub and new spokes) without removing the tire. Leaving the tire on, would mean leaving the spoke nipples in place. (It is a good idea to replace the spoke nipples when rebuilding a wheel. You will also require new spokes). It is a big hassle threading the spoke into nipples that are stuck in one ...

Not entirely surprised you have problems refer here...
According to this link, Cable Pull for a Campy 10 shifter is 2.8mm, dérailleur ratio for a Campy is 1.5 (or 1.4 for old) Cassette sprocket pitch for SRam 9 is 4.35.
So a single shift on the the 10speed is 2.8*1.5 = 4.2mm (ideal is 4.35). Over a 9 speeds that an error of 1.35mm, so when tuning, you ...

For those who aren't familiar, a SRAM Automatix hub is a 2-sped internal gear hub which shifts automatically, with the shift mechanism and everything contained in the hub. The mechanism is mechanical, and there aren't any batteries or anything involved. So, no cables to the back of the bike needed except for a brake cable if you have a freewheel Automatix (...

It lengthens or shortens the housing length to adjust the lateral position of the derailleur cage. It's used to adjust derailleur 'indexing' so that the chain sits properly on the cassette sprockets.
Mountain bike shifter units have barrel adjusters, road bikes use this one as well as having frame mounted or 'in-line' adjusters some where on the housing run....

SRAM acquired Sachs in 1997.
The main visible difference between the (Fichtel &) Sachs Torpedo 3 hub and the SRAM T3 is that the SRAM T3 comes in an aluminium body, whereas the Sachs Torpedo 3 comes in a chrome plated steel body and the brake design has been changed (but is compatible). There apparently was a successor model to the Sachs Torpedo 3 ...

This does not work in the specific case of a Sram CX1 rear derailleur, or the case of any other X-Horizon™ mechanisms.
I purchased the CX1 derailleur and attempted with a 46/39 front chainring combo. The CX1 RD allows the front shift to occur, but has no tolerance for changes in chain length (e.g. front shifting).
The change in chainring size impacts the ...

You absolutely need SRAM shift/brake lever units. SRAM road shift/brake levers are compatible with their MTB derailleurs and come in a 1x11 version.
Trying to mix Shimano and SRAM will just be a huge headache. I'm not even sure there is a shift cable pull converter for that.
Hydraulic vs mechanical calipers is up to you and your budget.
Something you ...

The thing with CF components is that you can't really tell much about structural integrity without specialized tools and knowledge unless it's obvious from the first glance.
Anyway, SRAM carbon fiber cranks have a healthy dose of paint and clearcoat, any damage to those aren't structural. Source: I own a set of S2200 that survived a bunch of pedal strikes, ...

If you want to upgrade gradually you need to follow the compatibility of the groupsets.
If your Tiagra groupset is the 4600 series of 2012, the 10 speed components should be compatible with other Shimano 10 speed road components, so you can use Dura Ace 7800 and 7900, Ultegra 6600 and 6700, and "105" 5600 and 5700.
The amount of cable pull per gear is ...

Bad disc brake performance is almost always either air in the lines or oil on the pads.
Air makes the levers spongey and oil stops the pads grabbing the disc.
Your problem sounds like air, a bleed should sort it out. A bad bleed from the factory is not that uncommon.
If you've patience you can try turning the bike so the line is as vertical as possible ...

In general, when you see oddly shaped teeth or variations on a cassette/chainring, its there to facilitate shifting (such as Shimano Hyperglide, and ramps/pins you see on chainrings/cassettes; see this link for some examples).
In this case, SRAM calls it their "Open Glide" technology. To quote them:
"OpenGlide tooth ramping allows for faster chain ...

Neither system is better than the other. In some situations, 1x is better, in others, 2x is better. As cassette range expands, effectively because the largest cog is getting bigger, the advantageous of 2x (or 3x) are decreasing. (SRAM just released a 1x12 with a 10-50 cassette, which is probably the nail in the coffin of 2x in the top end gear sets on MTBs). ...

Unwinding the spring, as the article states, will make the hub to shift when you're going faster.
Without touching the internals, the hub will shift at the same speed, no matter how high the cadence is. By changing the chainring-cog ratio you adjust the cadence at which the shift-speed is obtained.
So the answer is no, there is slight difference. By doing ...

Note: this is mostly based on my personal experience. Its an
incredibly subjective subject, so there is no right answer. Keep in
mind that in reality one level up or down will be completely
unnoticeable performance difference to most riders.
XT is considered the "Sweet spot" for performance, weight and durability. Probably X9 in the SRAM range. XTR ...

Sram apex is a double chainring crankset which uses a GXP (aka Giga-X-Pipe) bottom bracket which is an external bearing bottom bracket.
I think External Bearing or Outboard bottom bracket are both commonly accepted terms, however there are several different incompatible types of external bottom brackets such as hollowtech, GXP, and Ultra Tourque.

Yep, I've been using such setup for an year now, on my MTB (2x10).
See the "Technologies" tab on SRAM's page for X9 RD Type 2.
The equivalent technology by Shimano is called Shadow+ (note the +). When purchasing an RD, on can notice, that the price difference between having or not having the relevant technology is relatively small compared to the price of ...

To quote Art's Cyclery:
"Eagle drivetrains are not backwards compatible in any way (the exception being SRAM’s direct mount cranksets, which will still require a new Eagle chainring)"
and VitalMTB:
"SRAM will only make the Eagle chainring in the direct-mount style at first, and we were told it's the only Eagle component compatible with their 1x11 ...

You need any inline barrel adjuster.

According to this page yes, the hub
is discontinued and is no longer available
@armb's assumption may be true. They stopped making IGH's and dynamo hubs for the same reason, at the same time. I-light had such a small market share that it didn't even earned to be mentioned.

Technically you could, but it's a very bad idea.
The two fluids are incompatible and will contaminate each other, forcing you to re-bleed sooner than expected.
Whichever solvent you use to clean out the hose of mineral oil, will also be a contaminant for your dot fluid. In addition, you'll need some serious dedication and resolve to make sure you actually ...

SRAM and Shimano use different cable pulls and derailleur actuation ratios, so their shifters and derailleurs are nominally incompatible with each other.
This Art's Cyclery blog page documents derailleur pull ratios, sprocket spacing and cable pull for a variety of derailleurs.
SRAM and Shimano 11 speed mountain use the same sprocket spacing - 3.9mm, so ...

These bottom brackets use sealed bearings, which are in a metal casing. Unlike cartridge bearings, the bearings are not exposed and are sealed from the outside environment.
There are some bottom brackets that are are meant to be user serviced, like the chris king bottom bracket, but others may be much more difficult without specialized tools, while lower ...

Why do you wear chainrings quickly?
Cross Chaining - If you tend to be in the big ring on the back and the big ring on the front at the same time, you're probably doing it wrong. Same with running the small ring on the front with the small ring on the back. This can cause uneven wear on the front chainrings due to the awkward angles the chain must bend. ...

If your chain has a powerlink, you can disconnect it pretty easily. Otherwise, it is pretty straightforward to open up the cage and slip the chain out. It shouldn't damage it (as front derailleurs are pretty simple mechanisms).

I decided to put up another answer because while Daniel's hunch and Billy's excellent answer get at the gist of the solution, I did find some specifics that might help someone else (though perhaps only a SRAM S27 owner).
First of all, the service manual is pretty helpful.
In my case, the "end cap" was tighening on its own during rides. Normally, this ...

I did something similar last year but waited until I had all the components before assembly. If you are patient and you buy only when you think the price is the best you've seen there are deals out there. It was time consuming (18 months) but the savings can be worth it. I got an Ultegra groupset for about $600 one component at a time. With the release of ...

The balls are 2mm in diameter.
How do I know? Well, I found a bearing supply shop, and asked them to see some of their smallest balls. I bought one 2mm ball and one 3/32" (2.38mm) ball for all of 20 cents. The 3/32" ball was slightly too large to fit in the hole, so I tried the 2mm one, and bingo--a perfect fit. Putting the QR mechanism back together is ...
