A 29’er with a 28 tooth front chainring and 10-42 or 10-50 has a higher top end gear than your setup ;) that’s why some people are good with a 28 tooth ring.
10 tooth vs 11 tooth is a big difference and wheel size matters. I have a 32 tooth front chainring and 10-50 on a 29’er and can easily spin into the upper 20’s. To replicate the same top end on a 27.5 bike with 11 tooth you’re likely looking at a 38 tooth chainring.

It’s both gear ratio AND inch gears to consider.Quote:

A 32x10 on a 29er gets you 92.8” of forward movement for one full rotation of the cranks.
Same gear ratio of 3.2 but different inch gears.
Pedaling at a cadence of 100 in 32x10: (simplified)
27.5 = 26.2 mph.
29er = 27.6 mph.
They offer an 11sp 10-45 cassette with the same 12sp spacing for the XC race crowd. You just use the limit screws to lock out the derailleur. Saves a few grams and gives tighter gearing if you go 2x.Quote:

That 28t is gonna increase the antisquat in most cases. It may or may not bother you, but the difference is noticeable.
I’d really recommend rolling out your wheel/tire combo as well when figuring out your gears. Tire size will make a huge difference.

I broke my stem last week so used it as an excuse to get a new stem, bars and grips. Yippee.
picked up a beat wheelset on cl featuring a hadley ss rear hub and blown out rims
fresh bearings all around, dt comps, rim of choice, and a day twisting the spoke key got me some fancy new dj wheels

also finally found an ikon in 26x2.35 so threw that up front and giving it a try since schwalbe stopped making their only good tire the tabletop... :cussing:
Upgrade the saddle which has been really nice, and sprung for a spank oozy vibrocore handlebar and some new tires. And new grips...

I have a whole “ship of theseus” thing going on here man! once I have replaced everything but the frame, I’ll do the frame, then the wheel set and fork again...Quote:
