Re: Tightening Shimano Cassette lockring

You might find that the leading edge of the lockring is bottoming out against a component on the axle, like a dustcover. So, if you use a lockring of shallower depth it wouldn't happen.

Re: bcd 110 to BB30 bottom bracket

If your new crankset has a 30mm dia axle but is marked FSA '386' it will fit a regular threaded 68/73mm bottom bracket shell ... if you buy the correct bottom bracket. The new FSA BB386 standard is a crankset with a 30mm axle that will fit every BB shell out there. The old FSA cranksets with 30mm ax...

Re: Small gap in threadless headset

Yeah, look for a thin steel shim and re-assemble without it to see if the headset bind up.

If you need a thinner steel shim they can be found on the Internet.

Re: Any ideas what is up with my wheelset? Giant PA-2

Nope.

Yours are strong rims.

Perhaps stresses are just showing in the surface anodization?

Perhaps I am talking rubbish?

Re: Any ideas what is up with my wheelset? Giant PA-2

I had the same thing with some Rigida DP18 rims which look a lot like yours. I put it down to stresses in the rim which I assume started to increase as the wheel aged and spoke tension loosened off a little. This is how stresses in the rim manifest themselves visually. Road surfaces are crap in the ...

Re: Fsa bb30 cranksets

Stick with FSA. Their new 386 crank standard fits pretty much every BB shell out there, including your existing BB30 or PF30 shell. Means your crank will not likely become 'out-moded' in the future.

Re: Giant defy carbon. Bottom bracket creak

Whether BB cups or headset cups, always press in one fully and then the other, not both at same time.

Re: Front derailleur for 26-42 double

There's the special one from Interlock Racing Design, but I am not sure about it's compatibility with newer STIs.

If you fitted the third chainring life would be so much simpler for you.

Re: Easton "Gravel Shifting Rings"

The Easton crankset - according to the link - comes in 45mm chainline, whereas disc brake bikes have 47.5mm chainline. Or am I missing something?

Re: Tyre Size & Recommendation

22/23/25/28mm are all sizes you might consider.

What's important are the frame clearances. Fatter tyres might rub on parts of the frame.

Re: Shimano deletes Ultegra and 105 triples?

For anyone interested, the current generation of Shimano triple FDs have a channel in the inner plate where the chain needs to line up against when on the middle chainring for proper function. People think this means you can only use a Shimano triple FD with the 'regulation' front chainwheel combo, ...

Re: Gore windstopper washing confusion

Wash a Windstopper jacket in a non-biological liquid suitable for delicates. I use Persil Silk & Wool. Give it extra rinse as traces of detergent make it susceptible to wetting.

Windstopper is quite different fro Gore-Tex waterproof jackets.

Re: Dishing/centring/alignment tools for building wheels – recommendations?

I have the Unior one because it works with the tyre on as well. But if I was building more, one of the flat foot ones might be a little easier/quicker to use.
