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.

Ahh ok that makes a lot more sense. I should’ve consulted the gearing ratios chart! I’ve been wanting to switch to a 29ers so that’s good to know.

What have you bought/upgraded today.
It’s both gear ratio AND inch gears to consider.
There are many factors involved but to simplify it:
A 32x10 on a 27.5 gets you 88” of forward movement for one full rotation of the cranks.
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.

If you can borrow a 28t before buying one, or find a cheap one, It would be worth it. Most FS bikes (at least the ones I've owned/looked at) are designed around a 32t chain ring, 30t at the smallest. That 28t is gonna increase the antisquat in most cases. It may or may not bother you, but the difference is noticeable.
Remind me. We'll send him a red cap and a Speedo.

I’d really recommend rolling out your wheel/tire combo as well when figuring out your gears. Tire size will make a huge difference.

So I started with the base spec c30 Slayer a couple years ago and saved up for the transformation below.
SRAM Guide R -----> Formula Cura 4
Rockshox Deluxe ----> Ext Storia Lok v3
Volar rims and sram hubs -----> Nobl TR37 and Onyx Vesper Hubs
Yari Fork ---> Updated 2021 Air Spring
New Vibracore Handlebar
New XG 1150 cassette
I had a ton of fun on this bike over two years stock. Its now pretty much everything I dreamed it could be.

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...

Upgrade the saddle which has been really nice, and sprung for a spank oozy vibrocore handlebar and some new tires. And new grips...

Jeebus mallwalker, haven't you been talked out of continuing to upgrade your ride? Descend into the money pit already and get a new one! Here, I'll make it easy and sell you my current bike, I need to somehow offset the cost of the new one I just bought to make myself feel better about my non-functional wrist...

What have you bought/upgraded today.
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...
(I probably can’t get away with buying a new bike this close to the kid being born, but the current bike is riding better and better! new tires should make a nice difference...)Last edited by mall walker; 07-22-2020 at 02:46 PM.

^ haha fellas if there were another way I'd do it... but if a new bike shows up in my garage it's gonna make my life worse than pissing away a few extra dollars will......though I'd take the Crest bump anytime don't worry I've already got a lengthy spreadsheet of bikes I'll be choosing between next spring
