Hi All,
Road bike has 140mm on the rear and the rotor is just a cheap thing. Wanted to upgrade a while back but there didnt seem to be anything nice (sensible price, light, not ugly, works well) available.
With them being a bit more popular now whats a good option?
6-bolt only [edit]
Might fit one on the front but happy with 160mm so something i can get a matching 160mm would be good also.
Ta.
I don't know about road bikes but the 140 always seems a lot of fuss when looking into the kids hardtail... it's not like his weight needs a 160mm but 140mm means adding adapters instead of the front just bolting right on... by the time you add that I'm not sure it saves any weight...
[b]I usually go for simplifying my life[/b] ... I took off some perfectly good Avid DB5's just because I want to keep one set of spare pads and 1 bleed kit and the other bikes are all Shimano M685/M785 (and I don't trust the 7 yr old with DOT fluid)
I know 180/160 is popular as well but my trail bike is dual 180 as it just makes rotors interchangeable....so I need to carry less spares and can swap stuff between bikes if needed...
Weight Weenie wise (usually I only care on kids racing bike) the Ashima rotors seem pretty good so far, last set were a week from China and I think £12 each... and the previous was a Alligator Aries.... being a kids bike I stick away from any sawtooth type rotors ... better not to lose 10g by losing fingers 😀 .. I don't think you'd want them on a fat bike but they are probably fine for use on a road bike
I'm selling a Hope 140mm floating rotor for £17.50 posted in black if that's any use? 160's available to match also. details in profile if any interest.
I had one off B-S and it's very tidy 🙂
[url= https://www.evanscycles.com/aztec-stainless-steel-fixed-disc-rotor-EV173103 ]Aztec Stainless Steel Fixed Disc Rotors[/url] are £12 at Evans, light and pretty good - use them on our BMXs with no issues so far.
140mm on a road bike (mine anyway) is actually one less adapter. I don't think you need the power of a 160 on the back, seems odd that most new bikes are coming with them now. I'm after some of those hope discs too.
Hope on mine. They may even do a 'race' version which is lighter than the std one. Can't remember.
Aztec for me on my CX bikes for the last couple of seasons without any issues.
Light, reliable & transmit plenty of power.
Cheers all. As vintagewino says on most road bikes now 140mm is stock so no adaptors needed.
The Ashima rotors are pretty good* then and they do a 140, the 160 is 68g.
*I'm assuming that they don't really need to be as tough as an MTB and these do tend to be a bit easier to bend but you have a lot less force with 700c tyres
My last e-bay order arrived in 1 week
Prior to that kids XC bike had a Aries Alligator ... but bought the Ashima this time based on cost.
