First paragraph .....WTF?
Ideally for ride london the 100m route its worth getting at least tiagra/10 speed shifting. I would also recommend 28s. I agree an expensive frame is not needed. I did it in 2016; its a great experience and route.
Oh come on now... poor people do have certain faces and mannerisms, as do people from certain regions. For example, it's odds-on that a Scottish person will have a Nicola Sturgeon-esque face or similar and that Scousers go around with wobbly heads, wear tracksuits or pyjamas... it's inbuilt into their culture and genetics. I've never ridden a Carrera bike or Cannondale or any of the bikes you've listed, but if you'd read my previous posts you would have noted that I'd given a nod to the Carrera by saying that I spotted a few of the less affluent people in Ride London using them... so they must be pretty good for the money. To show I'm no snob I own a BTwin Mach 720 which is great, and I use it for winter - tbh it seems pretty much as fast as my main bike which is a Giant TCR pro, except the brakes are absolutely appauling in comparison for some reason (maybe they've picked up too much grit or something)... and the ride is not as comfortable generally - wouldn't like to do 100 miles on it. I also have a Boardman CX bike (that was disgracefully set up by Halfords by the way) that I just use to go out with my 5 year old son.... that has mechanical disc brakes that I rate worse than just normal clinchers.
Not everyone can justify an expensive bike even if they have the money available if they are casual cyclist and don't need a performance bike. Some would resent paying a lot more money to shave off a few kgs and add a few more gears plus have a generally weaker bike with more risk of structural failure, albeit a small risk. I'll have to admit I do have quite a few bikes of which 2 are Carrera's. I'm trying to think of any higher end bikes I have, I guess the best is my Cannondale CAAD road bike when they were made in the USA or perhaps my Kona Stuff. Again though a higher end bike would be wasted money for many it would actually be the wrong choice of bike whether they are rich or poor. As for your elitist comments about poor people have certain faces, clothes and attitudes I'll leave others to form their opinions on that. I've encountered rich people who buy low end bikes and poor people who go into debt to buy themselves a top end bike because they are brand obsessed. Personally I'm a strong believer in diminishing returns and both low end and high end products are best avoided with the middle ground often making the most sense.
I do believe he is jesting and you sir,well you are biting.
