All of these components are great deals, but Owen and I have gone through and picked out a handful of what we consider an absolute steal! Deals that make you say "woah, how could I not?"

Check 'em out below:

Picks from Adam

Starting on the Shimano side:

Shimano Dura-Ace R9100 Crankset

A crankset that generally retails for $825, but if you're okay with a little wear, you can get it for $249. It has 175mm crankarms and 50/34 chainrings. If these specs lineup with what you need, this is a hard one to turn down.

Pairs nicely with this Shimano Dura-Ace Di2 front derailleur for $79.99 (MSRP $449)

[product-block handle="shimano-dura-ace-fd-9070-di2-front-derailleur"/]

Plus a pair of these rotors for $29.99 each (MSRP: $59)

More of a SRAM fan? Here are a few killer deals for you, too:

2-by's aren't dead, especially when we're talking road. For those of you who still prefer two chainrings up front, this SRAM Force AXS 12s crankset with a power meter is a deal that's hard to pass up. $479.99 at The Pro's Closet (MSRP $1,110).

[product-block handle="sram-force-axs-d1-power-meter-12-speed-dub-crankset"/]

Pair it with this SRAM Force AXS front derailleur for $99.99 (MSRP $243):

Picks from Owen

Adam covered the road side, so naturally I’m taking this in a much more mountain-bike direction. Shocking, I know.

FOX 36 Rhythm Suspension Fork

Who doesn’t love a good fork? In my opinion, if you’re upgrading your suspension, the fork is usually the best place to start. Sure, switching from an air shock to a coil, or vice versa, can completely change a bike too, but that is a whole different can of worms.

The FOX 36 Rhythm is a great upgrade if you want a smoother, more controlled front end without getting completely lost in suspension settings. It keeps things relatively simple, delivers that buttery feel we’re all chasing, and should make a noticeable difference on the right bike. Just make sure the wheel size, travel, axle spacing, offset, and steerer length work with your setup before ordering.

Shimano Deore XT BL-M8100 / BR-M8120 Brake and Lever

I’m a big fan of XT brakes. They just work. Some riders complain about Shimano’s wandering bite point, and while hydraulic brakes can occasionally develop inconsistencies, a proper bleed and setup will often help.

Either way, you get plenty of power, that familiar Shimano braking feel, and a component I’d happily put on my own bike. At this price, this XT brake-and-lever setup is a steal.

[product-block handle="nc_shimano-disc-brake-assembled-set-j-kit-xt-bl-m8100r-br-m8120r-metal-padw-fin-1700mm-hosesm-bh90-sbm-black-1"/]

Race Face Aeffect R Dropper Seatpost

If your mountain bike doesn’t have a dropper post, get one. Seriously. It is one of the few upgrades that can completely change the way you ride by letting you move around the bike and get the saddle out of the way on descents.

Revolutionary. Nuff said. Just double-check your frame’s seatpost diameter, insertion depth, and the amount of travel you can run.

[product-block handle="raceface-aeffect-r-dropper-seatpost-30-9"/]

Shimano XT RD-M8100-SGS Rear Derailleur

Again, I’m a big fan of all things XT, and this derailleur is going for such a good deal that you may as well grab one. I’ve smashed a few derailleurs in my day, so having a spare on hand is never a bad idea.

Personally, I don’t think it is always worth buying the top-of-the-line derailleur. Can most riders really feel the difference? I pay far more attention to the quality and feel of the shifter. XT hits a great sweet spot between performance, durability, and not feeling completely devastated when a rock takes it out.

[product-block handle="6078494441664-shimano-xt-rd-m8100-sgs-rear-derailleur-12-speed-long-cage"/]

Shimano XTR PD-M9100 Clipless Pedals

These pedals are wicked good. Shimano SPDs give you a really secure, locked-in feel, and the XTR version is durable AF while still shaving a useful amount of weight.

They’re pricey at MSRP, so this is exactly the kind of component I’d rather buy used and save some cash on. High-end performance without paying the full high-end price? Works for me.

*note: price below reflects condition: used-good
