Re: Quill stem to A head adapter frozen in steerer

Looking at the photo, I think the stem has a shim between the extension and the adaptor, in which case the adaptor is 22mm/1"size all the way to the top. If so you can remove the handle bar extension then drop the forks out of the frame (undo headset etc) allowing access to heat the fork column...

Re: Need to reposition front mech?

If you change from a 110 to 113 BB axles, you might have to (ideally) lower ther mech a bit. With the 113 BB the mech needs to swing further out (by 3mm) to get to the big ring. In swinging further out, it also swings further up, so now has become too high. The effect may be significant, it might no...

Re: Used bike description

Crank scratching, looks like from a derailled chain from a poorly adjusted front gear to me. I'd say in a crash the crank wouldn't get scratched like that as the pedal would take the brunt of that.

Re: Padded Cycling Shorts - What Do You Wear Under - How Often Do You Wash

What to wear underneath - nothing. Far more comfortable. How often to wash. If its really hot weather, after each day ride. If it is more normal weather, I recon after 2 day rides is OK as I don't sweat much at all. Occasionally on tour 3 days if washing/drying looks tricky due to weather contraints...

Re: Van Nicholas Yukon

Not sure what you mean by"carbon alloy" (as a metallurgist that's steel to me!), or do you mean carbon fiber? Feel the fork blades. Metal (steel, titanium or alumimium) will feel cold (conducts heat from your hand), carbon fiber does not so will feel warm(ish)/not cold. (I'm assuming not a...

Re: Ornamental displaying of a bike

The last few times (I don't go there that often) I have walked out of Paddington station, just past where the police van is uually parked at the top of the slope, there has been a Kirk bike locked to the railings by the road. No sure if it has been abandoned, or just gets left in the same place.

Re: A cycle route near me

I had similar to you, not quite as bad, on a short stretch of cycle track leading down to a roundabout underpass (Kennington roundabout on the Oxford ring road).

Re: Bottom Bracket

The LH cup used to be plastic, now they are aluminium. A lot of other things creek too, the cup might be innocent of all charges. Check the axle/crank tapers are clean, and pedal (and BB) threads greased (or copper slipped) and secure. These can creek too. The bearings are almost certainly fine, exp...

Re: The Disc Brake Naughty Corner Thread

Can discs warp? If the disc gets hot, it expands. Expanding a flat disc can only be done by it warping (if old enough, have you ever left a vinyl record in the sun?). You can avoid a disc warping when hot by having the disc braking surface fixed to the spider arms by rivits that allow expansion radi...

Re: Should I worry about this?

Usually when a rim like this fails, the spoke pulls through the rim, so in terms of riding the same as getting a broken spoke. While I have never seen a rim loose its structural integrity when a spoke pulls through (ie, the rim stays round if some what out of true), its worth replacing sooner rather...

Re: Opinions - 531c for loaded touring

Probably a bit whippy/flexey if you do camping on 531C, particularly if you pack everything on the back. I'm a fan of low riders to even out the load distribution a bit. Something with 531ST might have more clearance for slightly fatter tyres + mud guard clearance also (I'm thinking 32c tyres here, ...

Re: Brand new freewheel - broken

I have seen this before, but not on new freewheels! As per Brucey, I expect a duff one. Shimano and Sunrace make similar freewheels if you feel the need for a different make. More usually I have seen the sprockets come loose because the lock ring has come loose/fully unscrewed. Wipperman chain sound...
