I have a ticking, clicking, crankset (Praxis Zayante Carbon S) or bottom bracket (Praxis M30 T47 E.B.), both of which are fairly new.
I know it's one of the two because I've swapped both out and eliminated the noise that way. Unfortunately I don't have another M30 crankset to check whether it's one or the other.
I'm certain it's nothing to do with the front derailleur, because I can hear it when the chain is definitely not anywhere near rubbing. It's not pedals or cleats/shoes - I've swapped them out to test.
It happens once per pedal stroke, with the right foot forward and going down. It's kind of intermittent, loudest when pedalling regularly at 250w+. I think it goes away at a high power, but I could be wrong there, the noise may be being drowned out.
Having test-ridden it a lot, I think I've never heard anything at all when in the big ring, no matter how I pedal. This lead me to conclude the problem is with the small ring/spider interface. The bolts for the small ring have their own threaded holes, they are separate from the big ring bolts. I cleaned and greased the contact points, and removed, greased and carefully re-tightened the bolts many times. I have stuck to the recommended 10nm torque, and tried to get them tightened evenly and gradually. I replaced the bolts with steel ones. I'm not sure what more I can do here? I could try threadlock on the bolts instead of grease. I could tighten the bolts beyond spec. Nothing I have done with the bolts has seemed to have any effect on the noise. When I found one had been a little loose after a test-ride, tightening it had no effect.
If the problem is not actually with the small ring at all, it could be the spider/crank interface (it's bolted on), but I've checked these bolts and surfaces thoroughly.
It could be the crank arm bolt, which is supposed to be tightened to 50nm. I don't have a suitable torque wrench for that, but at any rate, I think I've had it plenty tight.
It could be the bottom bracket, but I don't know what to do with that beyond removing, cleaning the threads, greasing and refitting. I've definitely had it on tight. The bearings seem to move smoothly, and I have the correct dust caps fitted (28mm x 2mm on NDS, 30mm x 1mm on DS)
There doesn't seem to be any unusual wear on the spindle. I can't feel any play in the crankset, but I have wondered whether the gap between the spider and the DS dust cap (filled by a wavy washer) is too large - it looks quite large to me, and the wavy washer is not noticably compressed (should it be?). On the other hand, nothing I have read about my set-up suggests I should need any extra spacers anywhere.
Does anyone have any suggestions for anything else I should try, please?

Paragrafrytter apparently means something like bureaucrat, so is this thread title a reference to the typical owner, something like 'the dentists' association of Cervelo owners'? -

To illustrate why I find the new route builder map so bad (apart from the waypoint issue), here is Stanage Edge on the old and new map. On the old one you can see at a glance the difference between North Lees (the road) and Long Causeway (the track) and minor footpaths. Now you have to actually put your route on it to see that Long Causeway is 'dirt'. Heatmap overlay is no help here.
If I look at an unfamiliar area, it's just a mess of white lines everywhere, and it's really not clear where to start. Here is old and new again. Three grades of surface are collapsed into two, and it's no longer clear that there are no asphalted through roads.

I don't get what's better about the new route builder? If I click and drag a point on the existing route to force a waypoint, nothing happens and I have to repeat the action several times to get it to work. It's a glaring fault and they shouldn't have released it like this. The route surface data they have is rubbish, worse than Komoot. The bright green map is awful to look at. As a paying user, I guess I'm going to make my routes with RWGPS now

I need a new rim for a rear wheel. Hunt Race Aero Wide, 24 hole, 31mm deep, 24mm wide
I'd like to get a move on with it, I'm waiting to hear from Hunt about a warranty replacement, but they don't have stock for a direct replacement at the moment anyway.
They charge £79 delivered for the rim, so if I end up having to pay for it, should I go ahead and get something else? I don't want to pay more than that, what's my best bet?
Edit: apparently their rim is a Kinlin xr31t, so that's my answer I suppose

There’s WhatsApp messages that state that the senior management team got Tom Watson who sat on the committee dealing with it to suspend ken Livingston for another year, rather than deal with it swiftly to harm Corbz.
I think it's likely that stuff like this went on, but the quote this is based on isn't proof of it:
Emilie Oldknow wrote that "Karie [Murphy] has been telling Shadow Cabinet members that I've orchestrated the Ken situation so... Tom got his people on the panel to make a soft decision. all in order to embarrass JC and create a crisis".
So she's reporting Murphy's opinion here.

This is my Bowman Pilgrims Disc, since replaced by the Weald. It feels not a million miles away from my summer bike and very handy on rough roads in winter conditions. -
Thanks, these look good
I remember I used to have some very comfy Hirzl gloves with a leather palm, and I'm kind of tempted by the Giro LX full leather ones
