This enables a smooth-riding of the bike. It also assures moisture and dirt resistance for the bike. Moreover, the bottom bracket is very light which again makes the ride an efficient one. The total weight of the GXP is g.
The GXP is available in a red-black colour theme. This colour enables a glow to the bike. There are little chances of rust on the bike because of the GXP. This helps it to be a lightweight unit. This also adds to the strength and the durability of the bike. There is no need tp side-load the bearing if any adjustments are to be made. Thus the GXP technology has made biking easier and more efficient.
This might add to the cost as an adapter will have to be purchased. The crank arms are straight, just like the GXP arms. They are basically the same as GXP cranks except the spindle is 30mm instead of 24mm. They're just like your GXP cups, but have a bigger diameter bearing to allow for the 30mm spindle.

Some more questions: - What does wide spindle mentioned below mean? I want to keep the chainline tight as possible - my goal is to use the large ring in all but the largest cog, and the small ring only for the largest cog up through the middle 6th cog - almost as a 1x set-up with a granny bailout gear.
So if a wider spindle means that the chainline grows, that's the wrong direction. By wide spindle, I mean wide enough to work with an 86mm BB shell. Which is the same width as GXP. I guess it would be better to call that a normal spindle, and to call the ones that only work with mm shells "narrow. Whereas a monkey could install a BSA system with a little grease and be trouble free for a very long time.
Bikerjulio - loads new but I'm on a budget so looking 2nd hand and due to the reasons mentioned everyone wants sram gxp cranks. SRAM and Shimano cranks are all available with 24mm axles, and a few more. They will work fine with 11 speed - I have 2 10 speed and one 11sp cranks, all on 11 speed drivetrains.

No BB creak at all. Not even after a few hits that loosen the drive side crank arm from the axle. However, haven't abuse them like I did to my Trigger. I demoed a Superfly BB95 few years ago at a Trek demo event, it was creaking loudly. Almost felt like it can be felt through the pedal. Maybe the guy rode it before me abused it? Who knows. Latest blog postings.
There'll be an axle in there, which turns in a pair of bearings: one on the right-hand, drive side of the bike, the other on the left-hand non-drive side. A bottom bracket on a bicycle connects the crankset to the bike and allows the crankset to rotate freely. The bottom bracket contains a spindle which the crankset attaches to. Bearings allow the spindle and cranks to rotate. Most Bikes from up use Mid Bottom Bracket. A 19mm Mid bearing is the same bearing size used on a sealed American BB.
American — These use bearings that sit inside cups that are pressed into the BB shell. Skip to content Lifehacks. April 29, Joe Ford. Table of Contents.
