SRAM Force 1 / Rival 1 with XX1 cassette

[Starter]

I'm 99% sure an XX1 cassette (10-42) will work with a Force 1 or Rival 1 setup (assuming the long cage 10-42 derailleur is used), but I wanted to check with the only people on the planet who might actually seek out such a configuration.

Obviously if one is looking for the lightest 10-42 cassette option, the XX1 beats out the Force 1, with the XG-1199 weighing 268g compared to 315g for the XG-1180. (unless an even lighter Red 1 option is revealed at interbike in a few days, ha ha)

I'm getting Rival 1 / Force 1 stuff, and I already have an XX1 cassette and a wheelset with an XD drive cassette body. 135 rear spacing on my CX frame.

Can anyone think of any reason not to stick with the XX1 cassette?

Yes, I know 10-42 is big for CX, but I'm in SoCal, where there are just as many gravel grinds as traditional races in a season, often on full-blown MTB trails with long climbs featuring serious grades...

Cheers!

i have a Trek Boone disc with 10-42 and force1 long cage, perfect work.

A Force or Rival 10-42 or the XX1 10-42?..

XG-1150, XG-1180 or XG-1199?

X01 , weight is the same of XX1 but cheaper

i contacted Aribike, an italian company: i want a 39T as final cog for a sram cassette . 42 is very low gear for road, in a steepy 20% climb too

i am using this set up with single 46T front ring

[rasmussloth]

Just get a 48t chainring...

[eliflap-scalpel]

no, 48T ring is too much for road use ...46T is the right size for climb everywhere with right cadence, right power, right heartrate

48T is killing you after an hard climb , whatever cog have you at rear, and you cannot go on on your ride with right freshness...

[rasmussloth]

But 46-39 gearing is heavier than 48-42...?

[eliflap-scalpel]

not only a ratio problem ...

42 is not required on road ride, even if you find a 20% climb ...

36 or 39 rear is enough, with a 42 you are riding over your cadence or too slow at your cadence.

but with a 46 ring.

with a 48T ring you cannot pedal in agility but in full power, boiling your legs after a steppy climb and lowering down in performances in the rest of the ride ... is not the right size for a all round use of the bike

[rasmussloth]

I do not agree.

With 48/10-42 you have (almost) the same low gear as 46/10-39 but also a higher gear.

[eliflap-scalpel]

not a problem if you not agree ...

i ride a 1x road bike since april 2014 ... in only this year, i rode 12000 km until today , with over 100.000 meters of climb

i tried 10 and 11 speeds, tried 11-34 , 11-39 and 9-38 cassette in 10 speeds, 10-42 and 11-36 cassette in 11 speeds, 38, 40 , 42, 44, 46 and 48 front rings, oval or circular ...

my opinion is that 46T is the best choice for front, 10-36 11 speeds ( not producted ) will be the best cassette, but fot now i want to stay with 10-39 in 11 speeds ...

i did 250km rides too, so for my use i reached the right knowledge for what is good or not, in gears.

i do not want to convince anyone, only share my impressions ...

run a 50, run a 52 ... as you prefer ...

[rasmussloth]

Great. You have a lot of experience. So do I and I respect that you have an opinion but from your posts it seems that you are only willing to go with 46t no matter what cassette options are out there.

I do not understand this:

"48T is killing you after an hard climb , whatever cog have you at rear, and you cannot go on on your ride with right freshness..."

You have plenty of gears on the cassette to choose from after the climb. If 46t is good after the climb I do not see why 48t isn't.

[eliflap-scalpel]

climbing at 20% with a 1x11 set up is different with 2x11

you have not the 34 or 36 or 39 small ring ... you have only that one...

46 and 36 or 39 is ok ... but there are various teeth of jump , so the 32 will be too hard ...

so you have to mind that you are using a mtb cassette and not a specific road bike cassette ...

so for this combinations , 48t is too big ...

[djconnel]

He means after the climb you'll be tired from using too big a gear during the climb.

I used to climb 24% regularly in 36/23, 36/26, 39/28 when I lived on Potrero Hill -- it was part of my daily commute. But it was only one short block. It all depends on how long the climb is. 36/23 is like a 46/29 or 48/31. You don't need to spin everything.

Watch the MashSF 2015 film trailer for guys riding fixed in SF. Then 11 gears will seem ridiculously luxury.

[rasmussloth]

Ok. I'm still not sure that I understand. But so be it.

Remember that Sram makes a 1170 11-36 cassette. It may be useful in many cases if you have a road hub instead of x-driver.

[eliflap-scalpel]

i have it ... it's made of real iron that cassette ...

i want a 10-36 XD body cassette 11 speeds ... please Sram makes my dream come true


rasmussloth : it's similar to ride all your ride with a 50T ring : try to do it and let us know after that ride how much are you tired

with 1x set up you have to check gear ratio, and your tiredness too ( laced to output power and heartrate )
