Installing Tannus Armor foam liners in the Eupree Stellar Falcon (27.5 x 2.8") — step‑by‑step install, tips for fitting in narrower rims, tube size recommendations, trimming tricks, and a real ride test to hear how the liners affect comfort and puncture protection.
What you’ll learn:
Why I’m adding Tannus Armor to my Stellar Falcon (puncture protection + smoother ride)
Exact tube size I used for 27.5×2.8 tires (2.0–2.4” tube recommended)
How to trim Tannus liners for narrower tires and avoid bunching — expect to do some trimming & elbow grease
Real ride impressions: noticeable dampening, softer hits over curbs, less vibration — how it compares with 4" fat tire installs
Other build notes: Cloud9 saddle, SunTour suspension post, possible auxiliary battery plan
Quick highlights
Bike: Eupree Stellar Falcon — 27.5 x 2.8 (Johnny Watts) tires, step‑through commuter build
Liner: Tannus Armor (trimmed to fit 2.8" tire)
Tube used: 2.0–2.4” inner tube for fit with foam
Install notes: foam takes up a lot of volume — remove from box ahead of time, trim excess foam, expect a tight fit and strong hands-on effort
Ride takeaway: softer, more plush ride over small bumps and curbs; good puncture protection for small thorns/nails (see my deeper Tannus test for limits)
