Commuter diaries – bike security! Check it out!

Based on my past experience with the Caledonia, tyre clearance is rather indicative. 34 mm fit if inflated at 50 psi, or else the rear tyre rubs against the frame. Other than that, a versatile bike that goes fast on the roads, shows agility on dry trails and makes cyclotouring pleasant. Glad they have a mechanical version.

"It was truly an unintentional act on my part" to drive some considerable distance at well over the speed limit, frequently on the wrong side of the road, blowing through several red lights, mounting the kerb and hitting multiple other road users until eventually I killed someone. Hmmm, yeah - easily done if your attention wanders for a moment...

I bought Cues 9-speed last November, even though it's probably not going on until next year, but without the front mech and shifter on the grounds that the Sora front gear probably isn't worn out

The footage here is worth seeing, particularly the overtake towards a small group of cyclists. Along with other descriptions of his driving in this case and "... the defendant had 12 previous convictions for 27 crimes from the age of 16 including robbery, aggravated vehicle taking and driving offences." But cyclists. https://www.bbc.co.uk/news/articles/cvgjn1rpwn7o

My goodness, you really are determined to defend your muddleheaded comment, aren't you? Firstly you tried lofty patronisation, telling me that I must be "misremembering or mischaracterising" the research I was quoting, then when I give you chapter and verse you tried to claim that I was selectively quoting (I wasn't, I was just quoting the portion relevant to our discussion, if I was going to selectively quote why would I give you a link to the original source?) and then tried to rubbish the source on the bizarre grounds that it is quoting a book that is "not freely available". You then tried to dismiss the research on the basis that "other information I find online" (no quotation, no source) disagrees with it. I mean really, hats (or helmets) off for trying, if nothing else. However, let's assume that your assertion that it takes a force of 1000 N to cause a simple fracture in a human skull is correct (it isn't, but let's assume). In walking trip falls where the subject's head contacts a solid surface, say a doorframe or a kerbstone, it's common for the skull to experience a momentary force of between 70-120 G. As I'm sure you know, 1G equates to approximately 9.8 N, so a person tripping when walking and smashing their head on a solid object can experience a force of well in excess of 1000 N. This makes your assertion that you don't need a helmet because the good old skull is pretty tough look fairly silly, given that it can fracture in a simple fall from a height of less than 2 m with no other force exerted upon it. By all means argue that helmets aren't an effective protection against skull fractures, but claiming that there's no need to worry about skull damage because it's pretty tough is almost as risible as your claim that your hair will protect you from abrasions, something about which I'm still chuckling days later.

+1 I much prefer them and would choose them over hydraulics if manufacturers made it possible. I find the difference in modulation is minimal and far outweighed by the ability to adjust the pad gap on the fly (not having to do 80 miles of a century, as I once did, with brake rub because of a warped rotor) and the ease of a simple cable replacement when necessary rather than the massive hassle of draining and refilling a hydraulic system. I am happy with the bikes I've got at the moment but when the new (secondhand) bike itch resurfaces I might well go back a few years in order to get one with mechanical, rather than hydraulic, discs.

it would stop all these oems using the rim brake brifters with mechanical disc brakes to save a few pennies on their builds I feel obliged to put in a word for mechanical disc brakes and the associated drop bar shifters - they're pretty good!

Theoretically, but the angle of the derailleur sweep would be wrong for 11-36. The current derailleurs are designed around a sweep the expects a 45T (or for the 1x RD, 50T) in the large cog position, not 36T. So it will presumably be further away than optimal. The spec sheet for the CUES 11-45T RDs say that's the only thing they will work with, but nothing else existed at the time either. I'm sure it would work, maybe just not optimally.

Tiagra 4700 is compatible with all the 11sp road stuff. Just not the 10sp. You could use 11sp road shifters with a 4700 RD, and have 11sp, or could use a 105 R7000 RD with 4700 shifters, and have 10sp.

So if I understand you correctly, I can swap a 11-45 Cues 11 speed cassette with a new R4000 11-36 cassette because the have the same spacing in-between spacing?
