BB sizes 113/118?
Published (2009-11-18 00:02:00)
2.5mm's worth of forked on both sides. But if you need a 113 and you ordered a 113 i'm confused as to why this thread exists.

They are not standard all-steel brazed or welded...

Mr Whirly Cranks...heads up

Surley is at fault and should take it back. The smallest ring should clear the bearings. If it doesn't, thats a sign of poor design.

bar end shifter and deore lx triple
Published (2009-11-18 21:01:00)
Here's a diagram of Shimano DT shifter (which has same basic structure as bar-ends; only the shift lever shape differs, and of course DT shifters are mounted on the brame instead of its own mounting bracket). Shows a bit more exploded than the Shimano diagram linked above. Disregard the cannondale-specific stuff.

Shmano 105 Issues

For the bottom bracket creak, if tightening made the creak go away for even a shot while, read up on how to install one, take the bike apart, and put it back together properly. It's likely that your LBS is skipping a step. If your frame hasn't been faced for an external bearing BB, get that done as well while it's apart. Shimano's BBs are high quality parts and unless you got a rare defective unit, it shouldn't creak.

Drivetrain changes on a Surly...
Published (2009-11-16 21:08:00)
I can see maybe a crankset swap to get some more usuable front end options for better ratios but why change the rear derraileur if it doesn't need changing? Or is it because you had a short cage and will now require a long cage? Seems like a CX bike should have a long cage by default unless it was all you had at the time. Don't pretty much all the front derrailleurs have enough travel range to cover a triple? No need to change it...

ISO 5775 Tire section width

That would give us 71.83mm and OD at 457.97 That's just a 5mm difference. How can this even come close to 'standard'? They're not...

I'm confused by your mention of a "click". you have bar-end shifters, and the left (front) shifter is indexed? my experience with Shimano bar-end shifters (both 8 and 9 speed) is that the left/front shifter is not indexed.

Should be fine with the slightly narrower tires, just be aware that a lot of 27" rims don't have a hooked edge to hold the bead at higher pressures. If this is the case, limit your inflation pressure to 75-80psi maximum even if you're using a tire with a much higher max. inflation rating.
As for tubes, tubes suitable for a 700 x 32c tire are perfectly ...

There are some very small headed bolts or sometimes rivets that hold the cog stack together. The heads will interfere with the spacer placed on the inside of the cassette so Sheldon recommended removing the bolts/rivets. I guess you could machine clearances into the spacer if taking the bolts out concerns you.

Are you asking if the extra click of the shifter will present a problem? No, you set the derailleur limit screws to lock that last position out. I suggest you make the shifter choice based on which shifter feels best to you.

Carbon anti-seize paste is readily available at bike shops and online. Any bike shop in your area should have it.

I am not going to say it is a great idea, because I don't know you at all.
How ever I just took apart my 105's and cleaned them up and replaced the main bolt, it was easy enough. There are most likely bearing in that thing so be careful. The ones in my 105 where loose.

I have a 5 yr old deore hub with comperable mileage, no pitting.
Subtle things can increase the wear, using a magnet to pullout the bearings might be one. It can magnetize the ball bearing which will cause particles of worn metal to cling to the bearing instead of float loose into the grease, it might also be a problem with your cups, are they worn also? ...

The 30T cog will probably work with your Ultegra RD but the 32 is very iffy. Some report success and some say it won't work. It seems to depend on your frame's derailleur hanger geometry.
As to the same chain, there are two potential problems:
1. If the current chain isn't long enough to allow big-big with the larger cog, you could have very expensive consequences ...

I've never tried the Swisstop green pads before. My poor weather favourites are Kool Stop salmon pads.
But, before you go buying more stuff, check a few things first.
- Do you have ample pull distance on the levers? If you adjust things too short on the pull, you get very little mechanical advantage and the brakes feel tight, but weak.

The process is called cold setting. While I am not sure of the exact spacing between 6 and 7 speed freewheels, the difference is small and cod setting should work with no adverse affects.
