Interestingly the water was not on the road when Astana went through exactly the same spot 18 minutes earlier than Jumbo. (I checked the video). Reminiscent of the incident when Cadel Evans rode through the tacks on the road.
Eurosport footage of the UAE crash (onboard) shows that the water wasn’t on the corner where they crashed but a few yards on. So it wasn’t like hitting ice and going down. And it wasn’t a big patch of water. Just goes to show how much on the limit they’re riding

And at the chronically unfit
And at the chronically unfit end of the spectrum, 115kg, 6 foot, FTP around 240W at the start of the year. It’s what happens when someone more suited to being a front row decides to hop on a bike. Think Chris Hoy’s Dad rather than the man himself.
Malcom stands by his wheels
Malcom stands by his wheels and is dead honest about what they will and won’t do. If you’re worried about heat stick with an alloy track or switch to discs – as he says heat buildup is a fact of life with any carbon rim.
There aren’t many builders out there who will rebuild a wheel for just the cost of the rim, given how time-consuming that is.
Great, thanks for that. The chart is very useful too – I hadn’t seen it before. I have 11-32 at the back anyway so it’s within range.I suppose the large cog lower limit must be something to do with the geometry of the derailleur and length of B screw not allowing the upper jockey wheel to get close enough to a cassette cog <32T when in the low limit position. In practice, this probably doesn’t make much difference and could also be typical Shimano conservatism based on worst-case assumptions on derailleur hanger design.
Ah, that makes sense. Maybe I’ve been fortunate but my approach with B-screws has always been don’t fiddle with ’em if it’s shifting fine. Unless you’re running a big cog well out of mech spec it’s not going to come into play.
Should work absolutely fine –
Should work absolutely fine – same pull and will just be a question of tweaking the limit screw to allow it to shift inwards enough.
Shimano don’t list it as compatible, but that’s because they see it as a 10-speed RD and, well, don’t cross the streams. Can be safely ignored because the pull is the same.
The only difference I can see other than weight (and the official speed rating) is that the minimum big cog that the RX400 is officially compatible with is a 32T so you might need a new cassette, particularly if you’re not already running a 28 or 30. On that subject, the RX-810 is only rated for a 30T minimum big cog.
Does beg the question why are there lower limits for the big cog size?
The R8000 front mech can be a
The R8000 front mech can be a bit fiddly to get the right base tension set. My LBS mechanic explained the best way to approach it was to over-tension slightly to get it set and then remove tension with the on-mech adjuster.
I can’t maintain 90rpm, don’t
I can’t maintain 90rpm, don’t have the cardiovascular fitness to do that. I can push decently hard at lower cadences, particularly as a larger rider.
Have to say it feels like 90rpm+ is for the pros riding 6 hour plus days. As with Matt I always feel I have to have a decent amount of resistance/load on my legs as without that I’m just not stable on the bike and that must in turn lead to efficiency losses.
Someone was championing their 5 grand bike that weighed nothing; I felt like saying, “and now you’re going to chuck 2 water bottles on it, a saddle bag with some spares/tool and you’re not exactly that ‘svelte’?”I went to a ToB stage finish (on my pub bike) and observed the legions of cycle club people turning up; the amount of carbon on the bike was directly proportional to the extra ‘lard’ on the owner.
Crap power to weight ratio means you need all the help you can get. I’m noticeably slower on my 15kg+ steel tourer than I am on my sub-10kg “fast” bike, particularly on climbs. Most of my climbing PBs were set when I had a 7kg-ish carbon bike a couple of years ago so bike weight clearly makes a difference to me. I’m only riding for fitness rather than racing but I wouldn’t kick some insane superbike out of the shed just because I’m a fat bloke. Each to their own.
You’re good to go. GS cage
You’re good to go. GS cage minimum max sprocket (if that makes sense!) is a 28T, and you’re well within capacity. You could have specced a short cage mech and still been OK, but having the GS mech shouldn’t cause any big issues – all you’ve got is a longer chain run through the jockey wheels than necessary, which I guess might possibly lose a tiny bit of drivetrain efficiency.
Always handy to have a GS mech available to my mind unless you’re just doing flat crits as it means you can whack in a big cassette if needed. The R8000 GS cage supports a 34T cassette (officially) and you’ll probably get away with bigger than that if needed.

The bike has never been dropped or crashed. Is it likely that the hanger and cage could be twisted from normal use.Yep – road debris snagging in a jockey wheel could do it. Or knocking it when you lean the bike against a wall. Hangers are designed to bend to protect the derailleur and frame.
Have a professional mechanic take a look, these things can be hard and time-consuming to track down. Ideally a Giant dealer just in case there’s a warranty claim required.So, hang on, he’s being
So, hang on, he’s being filmed whilst driving a vehicle? How is that even remotely safe?

One option might be to look for a local cycling/sustainable transport collective – there was one where I used to work and you could pop in and fit your own stuff with a little help from trained mechanics.
Interesting. The law in this
Interesting. The law in this area is cobbled together and I think they’re right, it’s time for it be simplified and updated. For example, you’re not allowed to watch telly whilst driving (but passengers can) but you’re allowed to pay attention to the huge screens that pass as dashboards on modern cars.
Likewise, you’re allowed to take a hand off the steering wheel to change gear or operate controls/switches, but not hold a phone to your ear. Doesn’t make a whole load of sense.
I see that the result of the parliamentary debate was “meh, we don’t care enough to make a change”To be fair, the parliamentary debate showed that a number of MPs care very greatly and there is cross-party support for increasing the maximum sentence for death by dangerous driving, but the government doesn’t have the legislative bandwidth to do much but Brexit.
The debate made it clear that the removal of the maximum sentence for offences is a simple piece of legislation to pass – a single clause bill was mentioned. That would be better than kicking it into the weeds. Whilst I find it reprehensible that drivers who kill multiple victims “kill one, get one free” that’s not going to change any time soon.
My long-standing view is that we need escalating sentencing for driving whilst disqualified (or unlicensed). All offences where injury has occured should result in a three-year ban with an extended retest following mandatory retraining, and if you’re found driving whilst DQ you go to jail for the length of the ban. I think that would be a much bigger deterrent than a possible life sentence.
