When you're shopping the bicycle suspension cockpit-the fork up front, the rear shock, and the small hardware that holds the system together-the first decision isn't brand loyalty; it's knowing whether you're fixing, upgrading, or building. This set of four parts spans a price spread from USD 12.99 to USD 114.99: a Trek Mino Link seatstay nut, two new rear air shocks, and a used suspension fork. The right pick depends on which part your bike actually needs and how much tuning you want after it's mounted.
Quick Take
Need a genuine Trek replacement for a Mino Link adjustment nut? The TAKE OFF Trek Mino Link Seatstay Nut is the lowest-priced item in the group. Want a new rear shock with a wide range of eye-to-eye lengths? The MEROCA MTB Air Shock is a mid-priced air shock with rebound and air pressure adjustments. Want more adjustability from a rear shock? The DNM Dual Air Shock adds compression lock, stroke adjustment, and damping. Need a 100 mm suspension fork? The Manitou Mars 1 is used, so it's a service project rather than a ready-to-ride component.

Product Notes
#### TAKE OFF Trek Full Suspension Mino Link Seatstay Nut (W529223)
If you own a full-suspension Trek with Mino Link, this genuine take-off nut is the hardware that lets you fine-tune the head tube angle and bottom bracket height. It is listed as new condition and comes from a brand-new bike, though it shows signs of installation and has no retail packaging. That makes it a direct replacement for someone who already knows the W529223 part number and just needs the original part back in place. The limitation is scope: this is a small seatstay nut, not a shock or fork, so it solves a specific hardware issue instead of changing the ride character.
#### MEROCA MTB Air Shock (165/190/200mm)
The MEROCA is a new black rear air shock for mountain bikes. Its listed eye-to-eye measurements run from 4.9 in up to 7.9 in, with travel from 18 mm to 47 mm depending on the version, so there is fit flexibility built into the range. The listed adjustment functions are rebound and air pressure, and it comes with an extra 8 mm x 24 mm top bushing. The clearest limitation is the amount of tuning control: if compression lock or stroke adjustment matter to you, the DNM listing offers those functions, while the MEROCA spec centers on rebound and air pressure.
#### DNM Dual Air Shock (165/190/200mm MTB)
The DNM is a new dual air rear shock described as an upgrade from the AO-36RC model. Its listed functions are damping adjustment, compression lock, air pressure adjustment, and stroke adjustment, making it the most adjustable rear shock in this lineup. The product attributes show eye-to-eye measurements of 6.5 in, 7.5 in, and 7.9 in, with travel at 35 mm, 50 mm, and 55 mm. It also includes both an 8 mm x 24 mm top bushing and a 12 mm x 16 mm bottom bushing. The limitation is fit range: it lists three eye-to-eye options, while the MEROCA lists five, so you need the DNM sizes to line up with your frame.
#### Manitou Mars 1 Mountain Bike Suspension Fork
This is the only suspension fork and the only used part in the group. The listing describes a 100 mm travel fork with a straight 1 1/8 steerer and compatibility with both V-brakes and disc brakes. It also states the fork is leaking oil, needs seals or service, and has an unknown service history. That makes it a candidate for a rebuild rather than an immediate install. The main risk is the unknown condition: if you're not prepared to do or pay for seal service, this fork isn't the right starting point. For a rider comfortable with that work, it's a way to get a Manitou mountain bike fork with a familiar spec.
Final Recommendation by Use Case
- If you need to replace a specific Trek Mino Link seatstay nut on a full-suspension Trek, go with the TAKE OFF Trek Mino Link Seatstay Nut, W529223 for a new-condition replacement part.
- If you want a new rear shock with a few eye-to-eye length choices and basic rebound and air pressure tuning, the MEROCA MTB Air Shock sits in the middle of this price spread and covers that need.
- If you want a new rear shock with more control from compression, stroke, and damping adjustments, the DNM Dual Air Shock is the feature-heavy option at the upper end of the price spread.
- If you need a 100 mm fork and are ready to handle seal service, the Manitou Mars 1 is the only fork in this group and gives you a straight 1 1/8 steerer.
