Do you have a lot of maintenance for calipers?

Replacing worn out rims is a bigger maintenance task than replacing worn out disc rotors.

This. The consumable components of the braking system become far simpler and cheaper to replace, as well as requiring less ongoing maintenance.

My Galli CP

I need Galli Hubs, shifters, seatpost 26,8, left crank 170, headset, stem.
good day to you
do not look, find

^ not more pornobscura Gaston... where will this end?

By the way, you also need these.

That's gorgeous Gaston!

I like how the Turbo badge matches the frame/callipers.

This. Using a potentially very expensive component on a bike as a braking surface has its very obvious downsides.

Hmmmm. Impressive. wipesmouth

Were you not in Tekken?

Hah, tis a username I can associate with. Yeah stopping on that kind of ratio was either total leg lock for little skid stops or my shoes would pop out of the clips, it was just too high a gear to safely slow down.

Any to the people talking about callipers, I never really thought I'd need to move up myself. This was an experiment after playing with my friends Orange P7 with Hydro's and thought ' Why not? '. Seriously though, I don't think I will ever go back. The feeling and stopping power is unparalleled. I thought the modulation would be scary and stops would be too sudden but it's like going from drum brakes to Brembo, love it. Shimano XT M785 with a 160mm Ice-Tec rotor is again, overkill, but worth it!

They r heavier uglier less aero more exensive and require new frames and wheels but yes they do stop better.

^ well put

Given the disc discussion, the timing of this may or may not be appropriate.

I put together a pretty detailed spreadsheet for mostly road-bike components that lets you spec out a bike, swap in and out various component parts (including wheels) and figure out how much the whole damn thing weighs. The list of parts and factory wheelsets is by no means exhaustive, I had to guess a few things and by no means is it accurate, but it seems better than manually building my own weight-weenie spreadsheet. My prime interest was to see how much weight discs would add to a road bike (300-500g) and how to minimise that.

Let me know if it's of any interest to anyone. If you want to contribute component weights for track bikes that would be really useful!

is that claimed or actual weight?

Actual when I could find the evidence, otherwise claimed. I didn't have the capability to weight anything myself.

Each to their own of course.

I do notice that the front is a bit heavier but this thing is still much lighter than my road bike which is a major plus. I only needed the front as well so it was a swap of the fork, stem, handlebars and wheel. I can list components if anyone is interested.

For doing 30mph at 90rpm.

Obvs.

It's a straight commute with 1 stop to work and back so there is little need for stop/start acceleration. But I can do it reasonably. I should put up a Strava run for people to see why I decided to run the ratio, I just hate spinning madly when reaching speeds of traffic ¯_(ツ)_/¯

Curious, but thinking there are no aero levers for hydraulic discs? Could run cable disc brake but not as neat. (Would not want to run flat bar pots)

So your idea cadence is 60rpm?

I should put up a Strava run¯

please do!

You can have a bit of mine for free...

20 sec off Steve Irwin :-S

There are aero levers for hydraulic brakes (magura).

Was not a swing at your setup at all. If you prefer discs for your bike / riding than thats all that matters and i mostly think its redundant for roadbikes. For commuters and such i certainly c the point just its a trade off i dont want to do personally just yet.

Oh no don't worry, no offence taken! Totally up to people to setup what the link, anything else is defer freedom. If you focus on weight then I can totally see why disc is not too salivating. I personally found though that the stopping power is phenomenal, and as such it really feels like I've gone from drumb to Brembo. Shimano's new setup that's coming out with 130mm and a much more slimmed setup for weight savings. I just couldn't wait @__@;

Out of interest, what sort of speeds do you average on your commute?

Dependant on the seaside weather but usually varies between 19-30mph
