I wouldn’t use a carbon bike on a turbo. Rollers yes turbo no. Frames is not designed to withstand the bending stresses that could be induced.Fair enough – your bike, your choice. It has turned out to be a non-issue world-wide thus far though, from what I can see, and there are manufacturers who say it’s fine with their own kit.. so it’s not inherent in the material. Lets face it, it’s not as though any bikes are designed specifically with the loads on a turbo and yet they still keep refusing to break.

Aye, not been able to for a long time IME either. The comment links seem to have been completely broken since the rewrite as well, not entirely sure how that’s been screwed up – that actually takes a high level of incompetence to do…
On the road, my risk of a head injury is roughly equivalent to that of a pedestrian and far lower than that of a car driver/passenger [plenty of studies to back this up] so rationally, if the risk of head injury whilst in a metal box does not warrant a magic lid, then neither does any less risky activities.My assumption is that airbags started to be fitted to cars to reduce the risk of head injuries and that helmets would not be practical in such situations as the is not always the head clearance in a car to wear head gear.
Aye, this, which does get mentioned – then seemingly forgotten – most times it comes up. Motor vehicles already do have elements designed to prevent or mitigate head injuries – air bags, curtain / side bags and to a lesser extent seat-belts as well. Whether that’s a good thing overal, e.g. risk compensation, is another matter.
I don’t care if cyclists decide to wear, or not wear, helmets and am vehermently opposed to compulsion but if we could at least not drag up this particular issue each time without context I would be a much happier man.

Wolf Tooth Components website might be worth a look, link to their adventure / gravel 1x set ups, has a useful chart to help with selecting gearing range…http://www.wolftoothcomponents.com/pages/1x-gravel-setup
The technical documents and 1x drive summary is also a worthwhile read.

Thanks for the links, been on their site a fair few times recently but missed both of these. Nice.
You have to be a real anarchistic rebel to type swear words on an internet forum.. I just worry what on earth these bad boys are going to do next ?Maybe move on to making bitchy comments?
Is snide > bitchy ? I never can remember…. 😉

[quote=Alfa a] Drivers pay little more attention to red lights at crossings than do cyclists.I agree with a lot of what you say, although I don’t experience the level of zebra issues you have, but this last line is something i’ve not seen anywhere in the country. Just my own experience but I would say that the proportion of cyclists ignoring (or not even seeming to register the existence of) red lights is massively higher than motor vehicle drivers – not entirely surprising in one regard as it’s hard to ‘sneak’ a Volvo across a junction without causing a minor war to break out..
I think the ‘bad behavuiour’ forms are different. Cyclists probably more likely to ride through mid-cycle if they think nothing is coming, cars more likely to ‘amber gamble’ and sprint through ‘as the lights are changing’.
Aye, agreed – that’s partly what I meant by the last bit, no mid-cycle motorists. The added danger with the amber gamblers is that, as you say, they tend to speed up – so any potential damage is increased. As for the cyclists – it’s a mish-mash that I see, especially in the city centre (Bristol).. some mid-cycle going carefully, looking for some space – some, mostly couriers, looking but then belting through – some others just seem to be staring off into space out front and very calmly just riding straight through at any point in the cycle… tempting to say the last group seem to be students but i’ve no idea to be honest, quite un-nerving to watch the serenity of them sometimes though.

Do you really think that Zwift will launch VR with anywhere near the current headset form factor..Give yourself a slap for that one
Come again guv ?
Agree with the comments above
Agree with the comments above about enjoying indoor work – it definitely can be fun – but would like to chip in on the endurance side. Proper time-crunched/HIT routines can most certainly improve your endurance fitness – you don’t need long rides to help with that as such. What longer outdoor rides will do is train your body to cope with actually dealing with the length of time endurance efforts require e.g. saddle suitability and bike position/comfort, fueling strategies, concentration and so on – and I gess also balance if you’re not on rollers inside 😉
Next thing – fan. Vital. You really don’t need anything too fancy either – for smaller fans something like a Honeywell HT-900 circulation fan (search on eBay and Amazon) or go larger with a floor mount from ToolStation or Screwfix. You’ll still be hotter than outside but it’ll be bearable and you might be surprised how effective even a modest air flow can be.
Tacx also has apps for calibrating your trainer and training which are Android compatible. They’re basic but useful.
Lastly your Tacx should normally come with a copy of the Tacx Training Software (TTS) – I know you don’t have a PC currently but it might be worth looking at what it offers to see if it makes sense to you to buy a cheapo PC for it. TTS has virtual reality courses (crits, mountains, rolling hills, velodromes) and events using them, training workouts, online events with other riders and a good range of very high quality real life courses (RLVs) to purchase should you wish. A PC that can run TTS can be picked up very cheaply and you can display on a TV, might not be your cup of tea of course but may be worth thinking about.
Enjoy.
On the subject of disc brakes
On the subject of disc brakes, my own position would be
* if possible, go full hydraulic. It’s far and away the least hassle with discs and (IME) the same/marginally less maintainence than rim brakes (pads go faster but simple to replace, less adjustment fitting or during lifetime). None too pricey either..
* if not, go for cable operated hydraulics like TRP Hy/Rd or (much cheaper) Juin Tech R1s. The latter are closed system so zero bleeding if that helps and have lever bite adjustment.
* avoid cable operated mechanical discs if at all possible. They’re not the worst thing but do take regular furtling to get the best out of them (they’ll be “OK” without, but you’ll notice the performance go downhill).
I have already managed to get hold of the rings for just £39 but wanted to make sure that I can swap them over before potentially spending a rather fruitless afternoon trying to fit them. As opinion seems to be divided on this it looks like I am going to have to give it a go anyway 🙂It’ll be fine, as long as they are 4-arm 110 BCD Shimano compatible chain-rings 🙂 Not sure why some people were insisting that they were different whilst ignoring the facts, it’s not like it’s an opinion piece… hey ho.
Edit : Nice price btw.
If you google replacement rings for the 5800 chainset, the cost of both rings is WAY more than the cost of a whole new chainset with rings.~€52 for 50/34 on Rose bikes

You will probably be able to get a 39 or maybe 38 tooth inner to fit, but the reason they are classed as compact is because the bcd’s are different. Normally 130mm on a standard and 110mm on a compact. On a side note, Stronglight seem to do their own thing.The BCDs are not different on the 5800, it’s 110mm like the other recent Shimano 4-arm chainsets.
I would assume the bolt circle diameter is different for each. If that is the case then it’s a new crankset I’m afraid.The 5800 chainset follows the recent Shimano approach of unified BCD – so compact, mid-compact or standard double will be fine.
