There's no denying it does work, judging from the photos.

Looking at the Shimano tech docs for the FC-RX600-1 and FC-RX600-11 cranksets, the GRX 1x11 and 2x11 drivetrains both use the same RH crankarm i.e. the 1x11 crankset isn't strictly speaking 1x specific:-

This is useful to know. As an aside, I think this also answers Jupestar's question on page 1.

Interesting. Useful update that may benefit folk in similar situations.

Apologies if you've already covered this, but was your original Shimano GRX 600 crankset (that you was previously using with the 1x set up) the 2x version of the GRX 600 crankset? Or did you originally have a 1x specific crankset and the bike shop has swapped it out for a 2x version?

The cranks in the photo look well worn so I initially thought you was using your original 1x crankset, which made me ponder for a bit.

The sentence is poorly worded so I wouldn't read too much into what "our pavements" means without the wider context. Elsewhere on their website they state that "Pavements are for People" and "Give us back our pavements" https://www.nfbuk.org/campaign/pavement ... or-people/. They go on to say "Cyclists: do not cycle on pavements or swerve in and around pedestrians on pavements, instead use the highway or dedicated cycle paths*. ..."

Elsewhere they mention the "reversal of more street layouts to restore the free movement of ordinary pedestrians and disabled and vulnerable people" https://www.nfbuk.org/campaign/shared-spaces/.

Again, the buzz-phrase "Pavements are for People" is poorly worded (maybe they didn't think 'pedestrians' sounded as good?) and they're also using "our pavements" again, but the context of the articles suggest that NFBUK don't think they own the pavements, but rather they want the once pedestrian-only pavements to be reinstated.

* Initially I thought this was only referring to the illegal and/or inconsiderate cycling on pavements but I think the inclusion of "the highway or dedicated cycle paths" implies that they don't want cyclists legally and considerately riding on shared use either.

The same model of Alfine hub is used regardless of whether the wheelset is disc or rim braked. There's no rim brake specific Alfine hub. The hub itself is fitted with a 'Rotor Mount Cover' which is removed if fitting a disc brake. It's item 21 on the EV:
https://si.shimano.com/en/pdfs/ev/SG-S5 ... -2788C.pdf

The EV also shows that item 1, part Y37N98010, is the correct internal assembly.

For interchangeability between the different models of Alfine hubs, Sheldon Brown website has a handy summary:

NB Shimano has changed their techdocs website and the links to it no longer work. Here's a link to the Shimano docs for the SG-S500 & 501 filtered on the EVs: https://si.shimano.com/en/manual/search ... 01,SG-S500

The actuator plate is part of the Driver Assembly Complete which is item 16 HSA 439 on HoogerBoogers EV.

Here's a post from Brucey about it:

HSA470 would seem the correct part.

Diagram 12 in Brucey's post is from Technical Information and Parts List for the Sprinter and Sprinter Elite Five Speed Hubs:

NB HSA470 isn't explicitly listed but it does appear in diagram 12.

I believe so. I originally thought the OP's title was simply made in jest, to poke fun at the poor wording of the original article. It never occurred to me before that the OP was being serious.

This was described as an "unusual Victorian tool signed Buck" on the reemandansie.com website. The auctioneers clearly couldn't tell that it was to cut threads (unlike the person on the Antiques Roadshow)

Hence I would focus on advocating against the NFBUK's call for action by Government to put an end to shared spaces rather than speculate on what they meant by the use of the word "our", the intent of which is explained anyway by their call for action.

But does it, if it was never a pavement before and it was built as a true cycleway that people were merely allowed to walk on?

You'll have to ask the NFBUK if they had your specific example in mind when they made their call for action. They may have had a more general view on pavement cycling.

Surely it should remain a cycleway and pedestrians who won't share would be banned from that section until a pavement is built.

I'm just pointing out the other bits in the same sentence as the word "our" in the NFBUK's call for action by Government to put an end to shared spaces that seem more pertinent. This doesn't mean I agree with it.

Sum

The important bit of that sentence are the words before the bit you've highlighted i.e. this bit; "7. Put an end to shared spaces, clutter, pavement parking & cycling on our pavements allowing us to move around without fear of accident or death." (My bold.)

If cycling in shared spaces is put to an end then the pavement that was once also a shared cycle path belongs entirely to the pedestrian anyway, i.e. "ownership" is effectively claimed regardless whether "our pavement" is used instead of "the pavement". I wouldn't quibble over the use of words such as "us" and "ours", I would focus on the "Put an end to" bit.

Your Mavic hub may be 11 speed road compatible, i.e. the freehub is longer than a 8/9/10 speed freehub, and may have been supplied with a 1.75 or 1.85 mm spacer. You will need that spacer for a 8/9/10 speed cassette.

Some Mavic hubs came with a 0.55 mm spacer to allow the cassette to clear the flange.
https://www.slowtwitch.com/Tech/Cassett ... _3257.html

Edit: Forgot to add that the Shimano CS-HG50-10 is a MTB cassette and won't need an additional 1mm spacer that some of the 10 speed road cassettes require to fit on a 'normal' 8/9/10 speed freehub. It's only the road cassettes CS-7900 / CS-7800 / CS-6700 / CS-6600 / CS-5700 / CS-5600 that require the 1mm spacer (according to the Shimano compatibility chart I linked to previously).

Sum

The higher-end Shimano 10 speed road cassettes are shorter by 1mm and require a 1mm spacer to fit on a 'normal' 10/9/8-speed, MTB 11-speed hub. The Shimano compatibility chart shows which ones:-

https://productinfo.shimano.com/#/com?a ... &cid=C-544

The lower-end 10 speed road cassettes don't e.g. the Tiagra CS-HG500-10, CS-4600 etc. SRAM 10-speed road cassettes are a direct fit without the need for such a spacer.

Sum

If the wheel has a 8/9 speed freehub, then you can use either a 8, 9 & 10 speed cassette or a MTB 11 speed cassette. The smallest 11 speed MTB cassette I can think of are the 11-34t CS-HG700-11 or CS-HG800-11 (105 & Ultegra) cassettes. Technically they part of the line-up for the 105 and Ultegra road series,

https://si.shimano.com/en/pdfs/ev/ULTEG ... _PARTS.pdf
https://si.shimano.com/en/pdfs/ev/SHIMA ... OP_v01.pdf

but I call them MTB cassettes as they come with the 1.85mm spacer that allows them to be used on either 11 speed MTB or road freehubs. The pitch between these sprockets is reported to be 11 speed MTB pitch (3.9mm) rather than road pitch (3.74mm), although they still seem to work with a road drivetrain.

If 11-34t is too wide a range then your choice is restricted to a 10 speed (or less) road cassette or modifying a 11 speed road cassette e.g. removing one of the sprockets. Although I'd only do the latter if I already had a 11 speed shifter and derailleur I wanted to use.

BBC Weather - Help and FAQs wrote:
Why does the wind symbol sometimes jump to over 40mph and turn black? Why are there no wind speeds in the 30s?

When the forecast predicts gusts of wind over 40mph, the white wind icon - which usually shows the sustained wind speed - will change to a black icon showing the expected wind gust speed. This black icon will help to inform you in advance of potential hazards that may shape your day, for example severe impacts on transport. Once sustained winds are above 30mph, it is more likely that the wind gusts will be above 40mph. You may find, therefore, that sustained wind speeds between 30mph and 40mph rarely appear.

May also apply to a degree (sorry) to the met office app, but haven't checked it in detail.

anyway, to the point.

I very often look at the day forecasts on the BBC app and in addition to the interval temps it shows the day max and minimum.

This time of the year, a pretty low minus figure (say 2 or 4) is often shown, but when I look through the hourly forecasts for the same day/night very often indeed I can see no temp which is as low as the one they have quoted. Very often the lowest hourly temp shown is a good 2 degrees above the supposedly temp pits/horror shown by the daily forecast.

What's occurring? - is the BBC app the tech equivalent of the grumbly soul who always looks on the dark side of weather?

According to the FAQs, there can be discrepancies between the max/min and the hourly forecasts:

BBC Weather - Help and FAQs wrote:There can be discrepancies seen between the maximum/minimum temperature given for the daily summary and the highest and lowest temperatures seen in the hourly breakdown. This is because the hourly value is given for "on the hour" whereas the max/min may occur between the hourly points so may be slightly higher/lower.

I usually notice a discrepancy of a degree, but not often 2 degrees, so I'm not certain if this explains it all.
