2015 Specialized Turbo

Archived: 2015 Specialized Turbo · Electric · Published sizes: S, M, L, XL

• Confirm the frame markings and seller description match this archived model. Note every component that differs from the published build.
• Record the frame serial number. It should be legible, unaltered and consistent with the seller’s ownership history.
• Find the size marking on the bicycle and confirm the fit before judging the condition or price.

Archived: Frame: Turbo alloy, smooth welds, fully-integrated down tube battery, internal cable routing, X12 thru-axle dropout, fender/rack mounts · Fork: Custom Turbo alloy, fender eyelets/Low Rider mounts · Aluminum

• Look for dents or shape changes and inspect the edges of welds around the head tube, bottom bracket, seat cluster and suspension mounts for hairline cracks.
• Stand behind and in front of the bicycle to look for obvious frame, fork or wheel misalignment. Ask directly about crashes, transport damage and repairs.
• Inspect the fork crown, blades, dropouts and visible steerer area. Check that it is straight, securely installed and free of cracks or impact damage.

Archived: Group: Electric mix · Shifters: SRAM X7 SL, 10-speed · Rear derailleur: SRAM X7 Type 2, 10-speed, long cage · Crankset: Chainway, 2 pc., w/ alloy bashguard, 48T · Bottom bracket: FSA MegaExo, outer-style · Rear cogs: SRAM PG 1030, 10-speed, 11-32 · Chain: KMC X10, 10-speed, w/ reusable MissingLink

• Shift through every available gear under light load. Hesitation, skipping or inconsistent indexing can reflect wear, damage, poor adjustment or mismatched replacement parts.
• Measure chain wear with a compatible gauge and inspect chainring, cassette or freewheel teeth. A new chain does not rule out wear in the remaining drivetrain.
• Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect crank arms, chainring bolts and pedal threads for looseness or damage.

Archived: Brakes: Formula C1, dual piston, Clean Cockpit clamp, 180mm rotor

• Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.
• Before riding, test every installed brake separately at walking speed. Each should stop firmly and release cleanly without its control reaching the end of its usable travel.

Archived: Wheel size: 700c · Rims: 700c disc, alloy double-wall, pin joint, 36h · Hubs: Specialized Hi Lo disc, alloy, RCC bearing system, QR, 36h, Custom Specialized G45c X12

• Spin both wheels and watch for side-to-side and vertical movement. Check spoke tension, rim condition and hub play.
• Inspect both tire casings for cuts, cracking, plugs, bulges or exposed threads and confirm the installed sizes are safe for the rims and available frame and fork clearance.
• Remove and reinstall or closely inspect both wheel-retention systems. Axles or quick releases should tighten correctly with undamaged threads, hardware and dropouts.

Archived: Headset: Ahead, cartridge bearings, alloy top cap, 8mm cone spacer · Handlebar: Specialized Stout XC, flat bar, double butted 6061 alloy, 9-degree backsweep, 4-degree upsweep, 31.8mm · Stem: Specialized 3D forged alloy, 4-bolt, 7-degree rise · Seatpost: Specialized, alloy, 2-bolt, 12.5mm offset, 30.9mm · Saddle: Body Geometry Turbo, hollow Cr-Mo rails · Pedals: Alloy, LSL sealed bearings, 9/16", w/ reflectors

• Apply the front brake and rock the bike to check for headset play or notchiness. Inspect the stem, handlebar and clamp zones, then confirm every fastener and control is secure.
• Check that the seatpost moves for adjustment and that the saddle, post and clamp hold securely without cracks, severe corrosion or damaged hardware.

• Inspect the battery case, mount, lock and electrical contacts for cracks, impact, corrosion, swelling, overheating marks or looseness. Confirm the battery charges normally.
• Confirm the correct charger, battery keys and removable system parts are included. Check charger cables and connectors for damage or improvised repairs.
• Power the system on from cold, check the display for warnings, and test every assist mode. Assistance should engage and stop predictably without intermittent cutouts or abnormal motor noise.
• Ask for available battery-health, cycle-count, diagnostic and firmware records. Confirm that replacement batteries and system support remain available before agreeing on value.

• Before riding, confirm both wheels are secure, tires are safe, both brakes function, and the headset, handlebar, stem, cranks and pedals have no looseness.
• Begin at low speed. Test steering, braking and shifting progressively, then load the drivetrain and suspension only after the basic safety checks pass.
• Listen and feel for repeated knocks, grinding, skipping, brake pulsation or movement at joints. Stop the test if the bicycle cannot be controlled safely.
