    42, 46, 50... rear cassette choices. Oh my!

    OK, starting to figure out a new bike. It'll most likely be a 429 Trail (to replace my current OG Mach 429).

    I'm a clyde and a crappy climber (the two are related, of course, but even at my best weight, I'm just not a great climber) so speccing the gears are pretty important to me.

    I'm intrigued by the Eagle (XO1) group, but not sure I need the 12 gears.

    An 11-42 just seems to come up a bit short, at least on my fatty (Borealis Echo) and I'm always looking for another gear, or maybe two. I'm going to put a 28t crank on the Echo, for now.

    The 11-46 cassette jumps from a 37t to the 46t and seems like a pretty big jump. I'm a crappy climber, but can still do a lot of climbing in that 42t cog. It seems like giving that up, for me, would not be a wise option

    The Oneup 45t conversion to the 11-42 seems like a pretty good solution/option to the 11-46, since it keeps that 42t and adds the 45t, where the 11-46 drops the 42t.

    I could go with a 2x set up and, with the 11-42 rear would probably have plenty of gears, but I do like the simplicity of the 1x setups. That said, I'm a function over form person, so if this is the best option, I wouldn't hesitate.

    Riding style is right in the 429T's sweet spot of "trail" to "enduro", but light enduro. I like longer rides with a mix of terrain and have even done some point to point trips (supported and "semi-supported", as in San Juan Huts) and will be doing more in the future. I can carry a good cadence and speed on level or very slightly up terrain, but when the trail tilts up....

    So, what say you, the assembled wisdom here... 1x12, 2x, 42, 45, 46 tooth? Something else?

    I'm not a true clyde, but 220 at 5'6". I have a sunrace 11-46 cassette. The spacing of the gears is better than the xt. It jumps from 40t to 46t. I run this with a 28t or 32t oval. The 28 oval is used on the triails I have lots of long climbs.

    Check out the Garbaruk Xtenders. Not the cheapest option, but still reasonable for what you get, considering how cheap XT cassettes are. All steel cogs, light, nice gear choices and you can go with a 48t or 50t.

    Sunrise 11-46 is your cheapest bet, about the same as 1 larger cog. They make good cassettes and the spacing beats Shimano.
