Bikes Depreciating Fastest in 2026 (Real Data)

Depreciation is rarely a graceful curve. It happens in chunks, around specific events: a generation transition, a category supply correction, a brand reputation shift. The bikes below are the ten model-year combinations losing the most value on the US used market right now, drawn from live listings vs original MSRP. None of them are bad bikes. Most of them are excellent buys.

We pulled the top fifteen used-median-as-percentage-of-MSRP gaps in the catalog, filtered to model-year combinations with at least five live listings (so the median is a real signal, not a one-bike outlier) and an MSRP of at least $2,000 (so the percentage discounts are meaningful in absolute dollars). The shape of the list is the point: depreciation concentrates around the same structural events across the catalog.

The fastest depreciation we see right now

• ▸2023 Trek Émonda: median $2,899 against $13,000 original MSRP. 78% below. Why: the 2023 generation predates the latest Émonda refresh, and the top-tier SLR 9 build was the MSRP anchor. Buyers willing to ride a one-generation-back flagship are being rewarded.
• ▸2016 Specialized S-Works Tarmac: $2,050 against $8,000. 74% below. Why: a decade-old top- tier carbon frame that’s still very rideable. The discount is mostly age + pre-disc-brake era, not condition.
• ▸2018 Specialized Roubaix: $995 against $3,500. 72% below. Why: the endurance road category depreciates faster than aero or all-rounder across the catalog, for reasons no one fully agrees on (one theory: endurance buyers ride more miles and resell tireder bikes).
• ▸2022 Specialized Crux: $2,464 against $8,500. 71% below. Why: the gravel category overshot demand in 2021-22 and prices have been correcting for two years. The S-Works Crux at this price is a real-world example of category-supply-correction depreciation.
• ▸2018 Trek Émonda: $2,024 against $6,500. 69% below. Why: a generation behind the current Émonda, just like the 2023 above. Different year, same structural discount.
• ▸2023 Specialized Diverge STR: $4,000 against $12,500. 68% below. Why: the STR's rear- suspension Future Shock chassis was the premium variant in a gravel category that was already depreciating fast. Buyers who want the STR specifically are rewarded heavily.
• ▸2022 Trek Madone: $4,660 against $14,500. 68% below. Why: the last generation before the latest Madone redesign. Same chassis, different paint, two thirds the price.
• ▸2022 Trek Émonda: $3,000 against $8,999. 67%below. The Émonda accounts for four of the top fifteen entries. We’ll come back to this.
• ▸2022 Specialized Diverge: $3,634 against $11,000. 67% below. Why: the second gravel entry on this list. The Diverge was the gravel category’s MSRP anchor through 2022; its discount tells you how far the category has corrected.
• ▸2023 Trek Domane: $3,200 against $9,000. 64% below. Why: the IsoSpeed generation. Trek refreshed the Domane in 2024 to drop IsoSpeed; bikes from the prior generation now read as dated even though they ride beautifully.

What this means if you’re buying

Every entry on this list represents a bike where the marketplace has decided what it’s worth, and the decision is roughly two-thirds below new. The structural story explains the discount; it doesn’t make the bike worse. A 2022 Émonda is still the same carbon climbing frame Trek shipped two years ago. The buyer paying $3,000 for one is getting roughly the same ride as the buyer paying $9,000 for the 2024 equivalent, with the same disc brakes and the same handling and roughly the same weight.

The two things to verify on any bike in this category: condition (a fast-depreciating frame two model years old has often been ridden hard) and groupset wear (a worn electronic groupset rebuild can cost $2,000+ and erase the discount). The buying playbook covers both.

What this means if you’re selling

Sellers anchored on MSRP minus a depreciation rule of thumb will set asking prices that the market ignores. The actual clearing prices on this list are roughly $2,000-$4,500. Listing a 2022 Émonda at $5,500 because "the rule of thumb says it should hold half of MSRP" means watching the listing sit for two months while comparable bikes at the median sell in two weeks. Run your bike through the price guide before you list.
