Truly the North Star!

Never far from my thoughts like many others I’m sure. Happy Christmas Brucey and all the very best for 2022.

Re: Best wishes for Brucey

There is a short update on the BigCoupe link above.

Like all of us my fingers are firmly crossed for a good recovery

Re: Taking Bikes by air - where to store the packaging ?

Hi
In case it helps there is left luggage in Geneva airport. It is towards the train station part of the airport building. Easy to find. I only used it for three days, so the cost wasn’t an issue but it might get expensive for a long trip.

Re: Buying Whole Bike from China

The thing you might find yourself reflecting on as you hurtle down a hill is that if there was a defect that required a recall, you might never hear about it. Whereas buying from somewhere reputable like Ribble etc. Would give you more confidence, and that might be worth the extra money.

Re: How did we delude ourselves about 23mm?

Interesting article here on the topic of tyre testing.

https://janheine.wordpress.com/2018/05/ ... isnt-easy/

Addresses the issues with testing on a drum, and the difficulty substituting a rider with a solid weight that doesn’t generate friction when jiggled.

The BQ testing methods seem more convincing to me than roller tests. This is subject to the limitation that they were conducted at moderate speed and so the aerodynamic impact of wide tyres may be understated, and don’t address the behaviour of wide tyres when climbing out of the saddle etc.

Is it true or just the industries way of getting us to buy new bikes?

It's a load of cobblers because the wider tyres are only better in the rolling resistance dept IF they are blown up to the same pressure as their narrower counterpart, which they aren't going to be in real world use, and then you get to the elephant in the room ... aero, wider is less aero and consumes more power to push through the air.


You only need look at the bicycle rolling resistance web page and you'll see that the fastest tyres are also the narrowest 23mm tyres, though on modern wider rims (a 17mm in the test rim on BRR) they come up to about 25mm. This is tested on a rough rolling drum, so sadly the wider tyre is faster nonsense is just that.

That said, ride whatever one wants to ride, I don't care, but when the proof of wider tyres being faster is absolute tosh and only in an extreme scenario which virtually no-one would do then I call BS.


I think the argument against this is that the steel drum tests ignore the rider, who absorbs energy being jiggled. If a fat tyre means the rider is jiggled less then more of the rider’s power goes to moving the bike forward and less to heating up the rider.

Re: Garmin 810 or wahoo elemnt

My use is similar to yours and I really like the Wahoo.

It is extremely user friendly, something I have never found with Garmin products (haven’t actually used the 810).

I don’t think I would describe the Wahoo’s maps as crude. They are in black and white, and don’t have contour lines, but they are detailed and clear.

Re: What frame material for my new bike ?

I’ve recently been going through the same thing.

My bike due for replacement was a 10 year old carbon road bike. Really liked it, but it was showing its age. It was fast, comfortable, light - I didn’t really expect a new bike to be any better.

I found an old (1992) Reynolds 753 frameset for sale, so I decided to move the parts from the carbon bike onto that as a stop gap whilst I thought more about what I should get as a long term replacement. I’ve always been interested in trying a 753 frame.

As things have turned out, I love the 753 frame. It is heavier than the carbon frame but is a delight to ride. I feel like I’m faster on it and don’t have any interest in a new carbon bike any more. So, as Brucey says, don’t count out steel.

Re: CTC Bag???

I used one last year. Flew from
Bristol to Geneva with easyJet no bother. Saddle out, bars removed and tucked under top tube, pedals off.

Stashed the bag in left luggage in airport.

Back 3 days later and same routine. Check in at Geneva was difficult. They wanted bike in a box. I eventually persuaded them. Then at Bristol I saw the bike being roughly (not drastically) handled. The top of the seat lug was slightly bent. Would have been better to leave the seat in.

For me the main advantage was I could leave the wheels in, which protects frame and mudguards.

Lightweight 700c 36 hole rim?

Hi

I’ve got a nice set of 36 hole hubs that I would like to build up for my summer road bike. I’d like a set of really light rims for them. Does anyone know of a good lightweight option that comes in a 36 hole option? Most of the obvious choices only come in a 32 max. The riding I do on that bike doesn’t involve much braking so if the lightweight comes partly at the expense of braking surface it wouldn’t really matter.


Cheers
