REI Co-op Cycles CTY 2.1: specs, upgrades and what fits
REI's suspension city hybrid, updated with a Shimano Essa 1x8 drivetrain (11-45T), a 63 mm SR Suntour coil fork and Tektro hydraulic disc brakes on 160 mm rotors; a step-through version (Graystone) shares the parts. The earlier CTY 2.1 used a 2x drivetrain. Best for: Commuting, paved paths and light gravel.

My take, from the specs
Good pick for commuting, paved paths and light gravel. The hydraulic discs stop well in the wet, the 1x8 with an 11-45 cassette is simple with easy climbing gears, and there are mounts for a rack, fenders and a kickstand. The 63mm coil fork adds weight, so expect a fairly heavy bike.
Sizes: XS: 5′0″–5′3″ (152–160 cm) · S: 5′3″–5′6″ (160–168 cm) · M: 5′6″–5′9″ (168–175 cm) · L: 5′9″–6′0″ (175–183 cm) · XL: 6′0″–6′3″ (183–191 cm)

Upgrade limits
How far each part can go on this frame, and why. Measure your own bike to confirm the estimated ones.
| Part | Limit | Why |
|---|---|---|
| Widest tire (current wheel size) | 40 mm | Unknown until measured. Your 19 mm internal rims suit roughly 28–49 mm tires. |
| Other wheel sizes | 650b up to ~47 mm | Disc brakes don't care where the rim sits, so a 650b wheel with a fatter tire fits. A 650b × 47 is about the outer size of a 700 × 28, so the bottom bracket sits about 12 mm lower than on 700 × 40 (watch pedal strikes). |
| Tubeless | Not recommended | Tubeless needs a rim built to seal (bead hook + channel) and tubeless-ready tires. |
| Valve type | Unknown | Decides which tubes and pump heads fit. Presta tubes fit Schrader rims with a grommet; not the other way. |
| Replacement wheels | Quick release · 100/135 mm · 6-bolt disc | Any wheel matching axle type, spacing and brake mount fits. Rear also needs the right freehub. |
| Biggest rear cog | 45T (now 45T) | Set by the rear derailleur (Shimano Essa RD-U2000 GS): max low sprocket 45T, total capacity ?T. A hanger extender can add a few teeth (hit-or-miss on non-Shadow derailleurs); a new derailleur is the reliable way to get more. |
| Front gears | 1x (40T) | One ring, no front derailleur. Adding a front derailleur needs a mount on the seat tube and a 2x crankset, so most riders change the ring size or cassette instead. |
| Chainring size | Unknown (now 40T) | Estimated from similar frames. Measure the chainring-to-chainstay gap to confirm. Check whether your ring is bolted or riveted. Spindle length (? mm) sets chainline; a big change in ring size may need a different BB spindle. |
| Gear count upgrades | 8 → 9 or 10 speed | Shimano HG 8/9/10-speed freehub: takes 8, 9 or 10-speed cassettes, Shimano 11-speed MTB and CUES/LinkGlide cassettes (7-speed needs a 4.5 mm spacer; most 11/12-speed road cassettes need an 11-speed road freehub, though the 11-34 HG700/HG800 fit). Shifter,… |
| Cranks & bottom bracket | Square taper · 68 mm shell · ? mm spindle | Any square-taper crankset fits with the right spindle length. Upgrading to Hollowtech II needs a new BB (same threaded shell). |
| Pedal thread | 9/16" × 20 | Every adult multi-piece crank uses 9/16". One-piece kids/cruiser cranks use 1/2". |
| Brake pads | TEKTRO E10 | Disc pads only fit calipers with the matching shape. |
| Rotor size | 160/160 mm now · front up to 180 mm | 6-bolt rotors. Going bigger needs a caliper adapter: post mount +20 mm adapter. Most steel forks allow 180 mm; check the fork if a max rotor is printed on it. |
| Caliper upgrades | Hydraulic system | Hydraulic: match the brand of lever and caliper. |
| Stems & bars | 1-1/8 steerer · 31.8 mm bar clamp | Any stem for a 1-1/8 steerer with a 31.8 mm clamp fits. You can cut a bar narrower but not wider. |
| Drop-bar conversion | Possible with mods | Needs road brake/shift levers (microSHIFT R8 makes 8-speed ones that pull Shimano 8-speed cable correctly), a drop bar, tape, and road-pull brake calipers because road levers pull less cable. Usually $250+. |
| Seatposts | 31.6 mm | Buy posts in exactly this diameter. |
| Racks, fenders, bottles | Rack ✓ · Fender ✓ · 2 bottle · Fork cargo ✓ | Threaded eyelets at the dropouts and seat stays take a rack and fenders. Fork leg mounts take cargo cages. |
| Max load (rider + cargo) | 300 lb | Wheels are usually the weak point under heavy loads. Stay under this with rider plus luggage. |
