Is any one running a 1x10 set up with the sun race 11x40 cassette. I am looking at running this cassette. My biggest problem is trying to figure out what to run for a front ring and keep the bike pedal friendly onto the black top. It is currently set up with a dram red shifters and a shimano six 2x crank. I would like to try and keep the front ring some where around a 40 I think as we are in the black hills of South Dakota. The frame is a 2011 Raleigh xxix that has been drop baredi think due to frame clearance it will need to sit on the inside of the out side spider. Thanks for any help. And sorry if this has been covered.

Here's a comparison.

I guessed your front is 26x36 with an 11-32 rear. If you run a 34 you split the difference between the high and low end. You can mess around with the chainring size in the gear calculator, just slide the chainring left and right. 

Main thing to notice is the big jumps between gears at the high end. That might be annoying.

Oh, then just sticking with the 44 gives you almost the same range (if you have an 11-32 in the back)

On one of my bikes I've got a 1 x 10 and bearing in mind I'm 61 and not exactly light (88kg) I run a 36 at the front with the Sunrise 11-42 at the back. No problem getting up hills and to be honest the 36 - 11 combination isn't that much of a limiter for me on the flat.

I'm curious why one would replace a 2x with a 1x, other than "one less thing to go wrong"? I mean is that it? Personally, I've had not troubles with any 2x setups so I don't understand the trend.

I can only speak for myself but now I'm retired I get almost as much pleasure from tinkering with my bikes as I do riding them, and crucially I have the time to mess about with them.
I did it to see what it was like. It didn't cost that much as I picked up most of the bits from eBay.
Now it's on, I quite like it. It's a simpler to think about - no more changing front & back mechs to get the "perfect" gear you just get on with it.
I did a rough calculation about weight and any weight saving (due to the enormous cassette on the back) could easily be negated by having an extra cup of coffee before I set off.
I still have 2 x 11 on my road bike where getting near as damn it it the best cadence is important especially in a group ride.
It's also easier to keep the BB area clean
One big advantage is that I can get a lower bottom gear (36 x 42)than with a 2x set up. I loose a lot at the top end but all that means is if I come off at speed I'll be going that bit slower! With that gearing the short steep hills here in the NW of England present no problem to my ageing muscles and lungs.

Running a 1x10 with the Sunrace 11x42 cassette. I run a SRAM Rival 1x front crank set with a 42 tooth for road events such as RAGBRAI and for the rest of the year riding SW Iowa gravel I have been running smaller rings. Currently running that cassette with a 36 tooth oval ring and i can still hit sufficient top end for gravel. Nice cassette. I just bought the 11x40 one for my MTB.

I get ya there!!! I am not retired but being an ex auto mechanic, I love working on my bikes as much as riding them. That's what my friends tell me anyways lol [wink]
