winky's new bike!

...better view than the inside of my shed.

Beautiful pic Winky.Wow  ! what stunning scenery - must be a very up lifting commute to work.I am lucky on mine as its on a cycle path parallel with the coast for 4 miles but no way as scenic as yours.

Pleased the bike is bringing you much pleasure

Careful what you wish for Tabby Cat.

This is typical of much of winky's route (Robson) . You can't see the driver of the grey car, but she is talking on her mobile phone,  whilst eating a sandwich and applying her make-up ! At least, according to winky, based on his posts elsewhere. And this picture captured the scene at 07:30 on a Sunday morning. Imagine what it would be like on a Monday morning at 08:30 !!!!

But winky's picture does capture the spirit of the North Shore, Lions Gate Bridge and Stanley Park which cover the rest of his route, so it's not quite as bad as winky often makes out

I actually just have three city blocks along West Hastings as part of my 25km commute (and I could bypass that by staying down on the foreshore). I was scolded by a motorist this morning for rolling slowly through a stop sign over on Bellevue. She must get very tired of having to scold the 99.999% of road users who do exactly the same. Or perhaps she reserves her scolding only for cyclists.

From my commute home last night.

Absolutely lovely....bike and view. Be safe.

A Wheel Fallacy.

The cycle wheel in the diagram (fitted with Maxxis tyres) makes one complete revolution in travelling from A to B.

It is somewhat obvious the length of the line AB is precisely the same as the circumference of the cycle wheel.

The hub of the cycle wheel (i9s) also makes one complete revolution along the imaginary line CD. And it is plain to see that AB = CD

Some people therefore seem to think that the length of the line CD must also be precisely the same as the circumference of the hub. But clearly, this is a fallacy.

There is no question that the hub makes one (and only one) complete revolution in travelling from C to D. But how do you explain that CD is not equal to the circumference of the hub ?

Great article and congratulations on your purchase and the ability to "finally “get Naked”!"

For the tyre, the tangential velocity (when measured from the point of reference of the hub) will be equal to linear speed of the wheel, or the tyre must slip on the road. The relative velocity of the tyre and the road is zero (the tangential and linear velocities exactly cancel) at the point of contact for no sliding. The hub has no such constraints. The tangential velocity of the hub is less than that of the tyre (for the rame rpm) as the radius is smaller but it doesn't matter that it doesn't match the speed of the wheel. The the hub essentially "slides" along.

Scientists,mathematicians and other boffins can not still fully explain why we don't simply fall over when on a bicycle in motion.

That's an urban myth. It has been explained. The steering is the key. The bike rider is able to steer the wheels back under the centre of gravity. The geometry of the steering is set up to assist this making the bike somewhat self stabilising.

What DOESN'T contribute is the gyroscopic effect. This was proved by building a bike with counter-rotating masses to cancel out the effect. It was still perfectly rideable. This is also supported by the rideability of bikes with really small and light wheels. But you can't ride bike with no steering.

You can ride a bike without steering, just not as far and you may tip over more often........

Here she is. Dura-ace hydro disc. Enve carbon cockpit.

 

It's been over a month now so how's the new bike going?

Are you happy with it?

My new bike will be ready sometime next week : )

Really good. The disc brakes are noisier in the wet than I’d hoped (and it has been VERY wet), but everything has been great. I’ve put in about 1400km so far.

What bike are you getting? Sorry if I missed it earlier in the thread.

A smudge of Coppaslip (anti-seize compound) or even some grease on the back of the brake pads might stop the brake squeal. It lasts for several months when I have done it. Why some squeal and others don't is a mystery to me. Pads not held tightly enough?

It's a factory off the peg 52cm size carbon fibre, the only similarity to yours is dura ace disc brakes/STI levers : )

Bruce, thanks for the coppaslip idea, will probably use it.

Plus perhaps some anti-biotics for those 'STI' levers?

I'd heard that tip, but with grease. I'm not sure I want sticky stuff inside my calipers and around the pistons. The build up of road debris in the calipers is bad enough as it is.

Coppaslip is commonly used on the back of motor vehicle brake pads for the same preventive seize, squeal, judder reasons so should be good for bicycles too, albeit the dinky size of the pads. My old Synapse Ultegra brake pads squealed so loudly when wet it was more than slightly embarrassing.

I was rather hoping the lated Dura Ace version discs would be fine, but from what you report maybe not...

I ordered my new bike on Monday. Bespoke. Not a familiar bespoke manufacturer, but definitely unique.

I visited the production centre today and took a few photos. Although it is basically complete, it does need some slight adjustment before I am prepared to accept it. I did mention the squealing brakes that both Debs and winky are suffering from. The bike builder assured me that I won't be able hear my brakes squeal.

I'll post a couple of pictures once I have uploaded them to Flickr.

Well, this morning we drove the 65 miles through beautiful rolling Wiltshire countryside to the small, secluded estate where this bike has been manufactured. We didn't get to meet directly with the manufacturing artisan, who I understand can be somewhat "laid-back" to the point of lazyness. His order-book has a 12 month lead time, but once he gets going, he knocks things out in no-time, a couple of days at most !

Mrs D considered the estate and more so the bike, to be more a work of art than simply the masterly bringing together of modern technology, and in a way, I can see her point of view. The bridge in the foreground, which forms part of the relaxing estate is a reminder of our infrastructure heritage but serves no useful purpose other than as a focus point when viewing the artificial lake and folly beyond.

Anyway, I digress. The bike !......see next post.

Fortunately, I didn't pay a deposit, and i'm pretty sure I didn't give him my address, just the e-mail address when I specified "something unique and outstanding" as I ordered on-line.

But I can see his point about the brakes not squealing.

With apologies to winky, Debs, Bruce and all the other cycling enthusiasts on this forum.

I really do appreciate your cycles and your enthusiasm and hope you can tolerate my attempted humour.

Nice bike, Ron!

Don't forget to put your number plates on it!
