X-LAB size-qualified local follow-ups
RS7 105 Di2: $2,899; RS7 mechanical: $2,099. Official Large = 56 cm, 176–183 cm. Both: new carbon frame/fork, Branta carbon wheels (C45/C50 references conflict), power-meter crank, 52/36 and 11–34 retailer gearing, 52/11 = 4.73 and 36/34 = 1.06. Di2 is Electronic; the other is Mechanical. Fresh Large online stock: Di2 Angel Wing White 47 / Singularity Black 21; mechanical Singularity Black 7 / Angel White Wing 28. Buyer-confirmed Almaden stock from October 13 is prior evidence, not today’s store allocation or hold. Exact unknowns: current store/color/hold, actual wheel/rim/hub and installed tire model/casing/tube or tubeless setup, rear axle/key, warranty, assembly and any destination fees, shipping eligibility, and safe lower-gearing conversion. Current Sports Basement policy lists $100 X-LAB shipping if offered. Current maker page was reopened for Large=56 sizing; exact tire/wheel conflicts remain as described.

Material availability change: Jenson’s Scott Addict RC 20 / Large (56 equivalent) now says “This item is unavailable”; its current storefront has no variants and no selected purchasable SKU. The prior $3,599.99 cached/indexed deal is removed from Current leaders and recommendations. The TPC CAAD14 /56 remains unavailable and excluded.
Other changes: all 13 retained dealer/CPO rows remain currently purchasable at unchanged advertised prices from October 19. RS7 Di2 White/L online quantity fell 48 to 47; Mike’s Synapse Yellow/56 fell 3 to 2. These are inventory-feed changes, not store holds or verified sales. No new verified dealer/online match displaced the current leaders. A new $2,099 private Áspero/56 all-road lead appears below with substantial specification gaps.

X-LAB size-qualified local follow-ups
RS7 105 Di2: $2,899; RS7 mechanical: $2,099. Official Large = 56 cm, 176–183 cm. Both: new carbon frame/fork, Branta carbon wheels (C45/C50 references conflict), power-meter crank, 52/36 and 11–34 retailer gearing, 52/11 = 4.73 and 36/34 = 1.06. Di2 is Electronic; the other is Mechanical. Fresh Large online stock: Di2 Angel Wing White 47 / Singularity Black 21; mechanical Singularity Black 7 / Angel White Wing 28. Buyer-confirmed Almaden stock from October 13 is prior evidence, not today’s store allocation or hold. Exact unknowns: current store/color/hold, actual wheel/rim/hub and installed tire model/casing/tube or tubeless setup, rear axle/key, warranty, assembly and any destination fees, shipping eligibility, and safe lower-gearing conversion. Current Sports Basement policy lists $100 X-LAB shipping if offered. Current maker page was reopened for Large=56 sizing; exact tire/wheel conflicts remain as described. If allocation is not reconfirmed, retain these as size-qualified local follow-ups rather than deleting them.

Best buy: RS7 105 Di2 at $2,899 remains the overall local equipment-value leader: new carbon frame/wheels, electronic shifting and power meter, subject to exact physical allocation and fee confirmation. Domane SL 6 /56 at $3,599.93 remains the better comfort-oriented electronic alternative, with IsoSpeed, 32 mm Hard-Case Lite tires, 38 mm clearance and a 1.00 low gear. Synapse Carbon 5 ($3,277.99 shipped-policy total) and the lower-priced mechanical SuperSix EVO 6 ($2,678.95) offer 0.94 stock gearing, but the latter needs wider-tire consideration. The unavailable Scott and CAAD14 are not recommendations.
Speed versus durability: RS7’s carbon wheels and road build suit pavement, but the stock 1.06 low gear and 32C ceiling limit steep-climb/rough-road flexibility. Domane/Synapse offer more endurance comfort or lower stock gearing. Extra puncture belts/reinforced casings can add weight or rolling drag; wider supple tires can improve comfort on rough pavement. Fit, tire pressure and actual clearance matter; no speed estimate or puncture-proof claim is made.
Optional puncture-resistance conversion, not stock: Mondo TLR 700x32 lists $89.99 each / $179.98 per pair, with maker-described 120 TPI 3-ply casing and puncture-resistant strips. Exact 32 mm variant stock is unconfirmed. Road sealant starts at $14.99: listed tire + smallest sealant package subtotal $194.97, before valves/tape/labor/shipping and before confirming sufficient sealant quantity. Complete installed price remains Unknown. Only use after a shop confirms rim/tire compatibility and measured frame clearance. No tire is puncture-proof.
Verification questions: Can the seller hold the exact size/color at a named store? What is the final pre-tax total including assembly/freight? What are the exact installed tires, wheel/hub model and cassette teeth? Is lower gearing approved without changing derailleur/chain? Which axle key or lever removes each wheel? What warranty, return-shipping/restocking and professional-assembly requirements apply? For used bikes, verify serial/receipt, current possession, carbon condition, batteries/charger, brake wear and compliance-system service.
Source coverage and limitations
- Craigslist: current Bay Area bicycle-for-sale searches screened 128 query-56 cards, 352 road cards, 80 Di2 cards and 49 AXS cards, with overlap. Retained and selected new direct ads were opened. Road pagination again redirected/repeated first results, so coverage is partial, not all Bay Area ads. Ads do not prove seller possession, unsold status or condition. Oakland Synapse/56 and Livermore Helios/56 still open at $1,699 and $3,200, respectively, but remain lower-priority seller-confirmation leads. An Oakland $1,100 SuperSix is 58 cm/incomplete; a Palo Alto TCR sale is Large without documented 56 equivalence; neither is ranked.
- Facebook Marketplace: both current San Francisco and San Jose 56-road-bike searches redirected to login; public-index searches did not yield a verifiable matching advertisement. No Facebook advertisement was verified. Login, location/personalization, indexing and robots restrictions prevent complete coverage.
- Bay Area shops: Sports Basement road catalog and selected products; Mike’s complete road catalog response (92 products) and exact candidates; Summit, Palo Alto Bicycles, Chain Reaction, Bike Connection, Encina/Clayton and Community Cycles road catalogs were opened. Exact stock proof was obtained for ranked local rows, not every catalog item or store floor. Encina’s Roubaix SL8 Sport/56 is unavailable; Bike Connection’s corresponding product is inactive. Physical allocation, store holds and exact pickup fees remain unconfirmed where stated.
- Direct brands: Specialized/Trek road catalogs, Canyon Endurace CF 7 Di2, Giant Defy Advanced 2, Cervélo Caledonia and Cannondale road pages were opened. Canyon shows $3,499 plus $99 estimate but member-login/size gates prevent exact required-size purchase proof. Giant advertises $3,300 plus $75 retailer freight without verified qualified-size allocation. Specialized Roubaix Sport shows $3,499.99 without independently established purchasable 56; a selector or generic price is insufficient. No generic M/L or 54/58 is accepted without manufacturer equivalence.
- Online/CPO: The Pro’s Closet retained direct single-bike pages and variant purchase states were rechecked. Jenson road catalog and direct Scott RC 20, Scott Addict 40 and Bianchi Sprint Di2 pages were opened: all three direct products now show unavailable/no variants despite attractive cached sale cards. Backcountry and Competitive Cyclist direct road catalogs returned HTTP 403; eBay’s current road-bike search also returned 403. Buycycle catalog entered a redirect loop. Newly opened US Buycycle Litespeed and SuperSix offers display $4,099 and $4,100 including buyer protection, before freight; these exceed the delivered pre-tax cap and have no verified California checkout or size/build resolution, so are not ranked.
- REI: current road catalog plus Synapse Carbon 5 and Synapse 1 product requests timed out directly. Web-rendered product views show sold-out/unselected states and cannot establish exact-56 California inventory. Current qualifying stock is Unknown, not an independently verified empty market. No REI bike is ranked.
- Policy/service limits: Mike’s shipping/returns, Sports Basement shipping/returns and TPC assembly/returns pages were refreshed. Mandatory fees remain separately stated. Summit’s old policy URL is now 404 and Chain Reaction’s old policy URL returned catalog content; those rows now mark current return/warranty/assembly terms Unknown pending confirmation. No nearest-authorized-service claim is made beyond named dealer/service evidence; remote CPO warranty transfer and professional sign-off remain unverified.
Standing requirements and scoring
Buyer: approximately 5 ft 10 in and 175 lb; exact 56 cm or manufacturer-documented equivalent; advertised complete-bike price at most $4,000 before sales tax. Non-tax mandatory fees are separate; unquoted delivery/assembly means the final budget is not cleared. Prefer carbon, hydraulic discs, Di2/AXS, low gear near or below 1.00, high-quality carbon wheels, easy wheel removal, durable 30–35 mm road tires or a verified wider/tubeless path. Model year and complete-bike weight are stated only when tied to this build and size; otherwise Unknown. Wheel lever/key details are Unknown unless established for the actual bike.
Component quality is independent of deal price, fit, condition and discount: drivetrain 30%, wheels/hubs 25%, brakes 15%, suspension/compliance hardware 10%, crank/cassette/bearings 10%, cockpit/post/finishing kit 10%. Scores are editorial integers, not measured performance: 9–10 flagship, 7–8 strong enthusiast, 5–6 dependable midrange, 3–4 entry/mixed or major specification gaps, 1–2 very basic/poorly specified. Unknown major parts reduce the score. Overall ranking additionally considers new/used condition, fit, road/gravel intent, service and final cost. Used aluminum with prestigious parts does not automatically outrank a new locally supported carbon bike.
