What, scared of water are ya?
Once I got to about 1 km north of the city, I didn't see anyone. It were just me on my humble commuter with mudguards and V-brakes which I find to be perfectly adequate, even in weather like today's...

I was out and loving having awesome bite from a good disc brake.rkelsen wrote:Where were all the disc braked ducks in Melbourne today?

Well done Michael, made it to twenty and I said it'd never happen.
lock it now?

Cheers. Nah the wheelset is the originals that came with it - and plastered in these horrible "Kona Payroll" stickers which have been removed
The rims are 30mm high and appear to be generic Deep V type copies, as they have a machined brake track. Hubs are labelled Xero and I think are 32H 3x.
When I change the tyres, I'll weigh the wheelset, but from other reports, they are not real light. Looks OK I must admit though.
As a separate report though, the 185/160 disc combo works really well. I thought that the 160 rear would be too big and was thinking of putting on a 140, but so far, no drama's. Don't need much pressure at all to get good braking, and no issues with modulation either, despite the big front disc
Another myth

Agree. I still find the 185 on the front the right size for drop levers, which are obviously harder to get good leverage from the hoods. My whole setup looks a bit odd, but it isn't about weight and looks as some would have us believe. It's about the right balance of performance for the application.MichaelB wrote:As a separate report though, the 185/160 disc combo works really well.

185 front sounds interesting, especially now that I'm using 105 levers - that might get me back the modulation I had with Rival...

Looks nice - much cleaner than the TRP and Hope solutions. By the time it comes out I'm expecting an announcement from SRAM or Shimano that will probably kill it, though.

Interesting comments there re the cable vs hydro.tony_farrelly wrote:
And why would you want hydraulic discs on your cyclocross, road, or touring bike? Stopping power is the answer - you can already run mechanical discs with drop bars, and while they are more powerful than conventional cantis or dual pivot brakes they don't have the outright stopping power, and lever modulation of hydraulic discs. Hydraulic systems are usually self-centring - so you don't need to adjust them - which is pretty useful too.
Like them only slightly better than the other versions out there, but still not enough for me to want to change from what I have

Just needs some clever handlebars that have some recesses (much like they already do for cables) to minimise the impact on bar shape, and it's then a neat package. I can imaging hydro capable STI levers would be expensive.
On a separate note. Did my commute to work this morning via Mt Lofty. Had been raining, and 1/3 of the way up the climb, it was very misty. As I went up, I could see some riders descending slowly with an almost terrified look on their face as they approached a corner and having to brake miles early and listen to the grinding of their rims.
Made me smile just a wee bit

Better to stick with a standard lever modified with a pressure sensor at the pivot, the lever won't have to actually move so it could be set perfectly for your hand size. Fly by wire in combat aircraft uses a similar setup.

I work in a radio frequency field and can assure you that, in the real world, I highly doubt you would have that specified minimal failure rate. Electronic brakes are a bad idea, wireless is even worse and adding a battery to it is worse still. That is without the 2 metre calculated delay at 30 Km/h. Bicycles have enough trouble braking quick without adding 2 metres to the stopping distance.

To put it in perspective, if you used the brakes once every second, non stop 24-7, it suggests a mean time between failures of 1000 years...Nobody wrote:I highly doubt you would have that specified minimal failure rate.

Exactly my point. How many electronic devices do you know of that last even 10 years without some kind of problem in the real world?
