Running a 50x12 at the moment

Why?

50x12, why?

Why?

For doing 30mph at 90rpm.

Obvs.

Pretty much. Running a 50x12 at the moment and after 3 months it was getting old fast. Plus had some nightmares with callipers in the wet with the other bike. The modulation on this is very impressive, hard decelerations at 30+ mph is easily done. Don't think I'm going back anytime soon!

Hmmmm. Impressive. wipesmouth

Were you not in Tekken?

you still as pretty as this or did they manage to fix yo teeth?

that picture reminded me of this gem

Wow I remember reading about the crash at 1:54 in a BMX mag years ago....did his leg up really bad

It's for slowing down or stopping without wearing out tyres and knees. Plenty use them.

Discs are probably the most efficient form of brakes in wet weather.

Hope that helps.

But surely a normal road caliper brake is just fine? if your that worried why not be on a CX bike or something?

We all thought drum brakes on cars were fine in the 1970s. It's 2014, rubbing your rims with lumps of rubber to slow down is getting old.

You have no rim braked bicycles?

Yeah but they were shit, modern road brakes can be very good.

Until you tried disc, which is what tester is getting at.

Plenty, but then some of my bikes are old and some of them don't need good brakes. If there's serious stopping to be done, I'd rather have my 4-piston calipers and 8" discs.

Or perhaps its just not for everyone. Im not even close to wanting discs on a roadbike and i do 95% of my riding in the city in all weather. I really dont understand the "need" for discs on paved road racing / riding at all.

I really don't understand

fair enough.

I take it you've never used a hydro disc?

Hate to sound like a broken record, but have you used disc brakes before? the difference is much more predictable, especially when you no longer have to worry about the brake limitation, instead, worry about the tyres limitation.

I dont worry about brake limitation as is. Yes i have had 2 cross bikes with bb7s and a couple of cannondales with hydraulics.

I'd think discs on the road are particularly useful on long fast descents with carbon rims when you don't want them to melt.

I still cry over mine...

And incredibly light too, not having a braking surface mean you can easily go under 400g for a 700c/29ers rim, like the ZTR Crest weighting 340g without any loss of strength.

They're releasing the ZTR Valor soon, check the weight, the rims is under 300g easily;

Rim brakes still work fairly well when conditions are good for most stuff. But for me at 90kg and in the wet they can be hairy at best. Need to constantly dry them out by stabbing at them in the rain. No such worries with disc brakes.

Maintenance is the other big thing, particularly for something that gets ridden through the crud of winter. Can't get much more set and forget than self-adjusting hydraulic discs.

Think this pretty much closes the argument. maybe your physique/technical skill/landscape doesn't entertain the notion, but for those that do, disc brakes is a sound consideration. I'm glad to see the technology spread into road bikes, and hopefully it'll progress with quality, weight loss, etc as more firms get involved in production. I currently don't have a bike with db and wish I did again, particularly with current conditions and the majority of my riding being in Cornwall.

Was running hydro Magura on my old Norco with hookworms in central a few years back. I got addicted to pulling endos at junctions. Got my ass handed to me on one occasion in front a queue of traffic. /csb

Do you have a lot of maintenance for calipers? Id say i spent far more time with the discs than i ever did with calipers.

I spend about the same with disc after setting them up, the only annoyance with BB7 is that it's not self-adjusting.

The TRP Spyre should change that, already quite impressed with the performance of the BB7 Road.
