Thinking of buying a TT bike now but perhaps I should hold off until spring 2019 when they come with disc brakes. Aero benefits, wider tyres, greater stopping power and more bling..

Also did Canondale not release a TT bike for 2018?

No, no, yes, yes.

So the answer as to whether you should wait seems to be 50/50. Smile

Sorry, but having a huge block of an ugly mechanical mess bolted to the most visible part of the bike isn't 'bling' in my books.

They look ugly as hell.

Since when have "bling" and "aesthetics" anything to do with each other?

There are only a handful available at the moment, and they are top-end bikes (QR PR6 Disc, Parlee & Super Slice). I don't think you can buy the Super Slice yet in the UK? But just like road bikes, it will trickle-down soon enough.

You only have to look at the Parlee TT bike and the latest Scott Foil, to see how the aero-integration is already improving. Once the industry turns it's full attention to aero disc bikes, then the results will improve dramatically.

Is it the looks, functionality or both that you're not in favour of?

This is probably the first time ever, I've seen you not advocate for new technology.

Which technology do you think I've advocated for ?

As I have said many times, I have no problems with anyone using whatever they like, but that when people claim 'X is better' with zero evidence they get all snarky.

But to answer you point - yes they look pug ugly, and I contend that for the vast majority of road miles, they offer no advantage at all. People who spend 99.9% of their road miles either going slowly, going flat, not in the rain, are wasting their money.

Technology improvement generally comes as a rest of a defined need in response to a defined problem. Better brakes on cars came about because cars were crashing all too often and people died. GPS devices on bikes came about because people wanted to know their statistics and they couldn't improve because they couldn't record their data in real time, or that they were always getting lost Smile.

Allegedly 'better' brakes on a bike - a solution looking for a problem which doesn't exist in the overwhelming majority of use.

But that's where a lot of riders would disagree i.e. they believe their riding does benefit from the use of disc brakes. But obviously we can't put a number or statistic on that; but generally, riding on UK roads in normal UK weather, many feel disc braking offers a distinct advantage.

Given your move to eTap, what advantage do you believe wireless electronic shifting offers over well maintained mechanical, in terms of shifting performance? We've already witnessed one big weakness - you losing the batteries.

That doesn't alter the statistics that the overwhelming vast majority of miles do not result in brake fail carnage. Sure, they can believe whatever they want, but that doesn't make it true. Its like painting a bike red in the hope it makes you faster. Its the blind claims of 'better' being a fact and making that claim to everyone I have a problem with.

No meaningful advantage whatsoever. But it looks nicer to me and that's why I don't go around telling everyone that eTap is right for them and its 'better'. I only bought them because I had the money and I'm too lazy to keep mechanical ones adjusted.

True. Although I'm happy to claim that with full-carbon rims, disc brakes perform better in my experience, particularly in the wet!

Yes, fully understand that, it does look good and does away with gear cables. My only reservation is reliability and redundancy, and the fact I really don't like double-tap shifters (do eTap levers work in the same way as the mechanical shifters?).

The overwhelming majority of bike miles don't need brakes at all. You don't want decent brakes for the 99% of time you are riding on flat dry roads away from idiot drivers, you want them for the 1%, or 0.1% or 0.01% of time you need to stop to save your life (or just avoid an embarrassing trip to the hedge).

I don't think you are denying that disc brakes offer superior stopping power in certain conditions, and no worse in all others. So why not choose that option if stopping is important to you?

But when you see people riding in the dry on the flat, slowly, telling everyone that disc brakes are much better I have to laugh. We get them here - in the sand on an optically flat track (like 25 feet rise in 20 miles yesterday) and them doing 16mph telling us how the brakes make a difference. You hardly need brakes here unless you're in a pack.

You tap once and they change. Its as simple as that. There's a tiny lever behind the brake lever but instead of forcing a cable to move (and maybe moving the end of the lever 1 inch or more to get the cable to move enough, it only ahs to move 1mm. Unless you use the granny ring you can get by on one battery as it only needs one to change the rear shifter.

The only practical difference is that the left button moves the rear shifter up to a bigger ring and the right one moves it to a smaller ring. Press both and the front changes. Its very smooth and there are those who say its not as quick as a mechanical and they could be right but I'm not good enough to tell.

Its also integrated into a Garmin so you can see gear ratios, shifting patterns usage etc while actually riding.

At the end of the day there will be a small, but very vocal minority, who will never like disc brakes. However, the reality is that in a couple of years there will be almost no new bikes without discs. For manufacturers it simply doesn't make economic sense to design and build 2 variants of the same bike

You may only need them once...
