Calibre Bike Covers — Bossnut, Two.Two & Sentry
Calibre is a British brand making value-focused mountain bikes — the sort bought as a first proper trail bike and then ridden all year round. They earn their keep in the wet, and with wide bars and mud-caked tyres they rarely make it past the hallway, so they tend to live outside against a wall or under a lean-to.
Every Calibre model in our fit database takes the XL / MTB, the wider of our two covers.
Which BikeParka fits your Calibre?
| Bike type | Models | Recommended cover |
|---|---|---|
| Hardtail, trail and full suspension mountain | Two.Two, Line, Dune, Triple B, Bossnut, Sentry | XL / MTB |
A dropper post left up, a bar bag, a bottle cage or a rear child seat changes the shape more than the frame does, so send us the model and what is on it and we'll check the fit.
All BikeParka covers are waterproof, seam-sealed ripstop and PFAS- and PFC-free, and pack into their own Stuff Sac. The XL / MTB has brass eyelets at the hem, so you can thread a cable lock through the cover and around the frame.
Which size cover?
Handlebar width is the deciding measurement. The XL / MTB takes bars up to 100cm, and that is the cover we recommend across the whole Calibre range. The narrower STASH and URBAN stop at 63cm and are meant for road, gravel and city bikes.
Calibre cover questions
Which cover fits a Calibre Bossnut?
The XL / MTB. It is cut for handlebars up to 100cm, which gives the Bossnut room to spare.
Is there a cover for the Calibre Two.Two?
Yes, the XL / MTB. The Two.Two, the Line, the Dune and the Triple B all sit within its 100cm handlebar limit.
What about the Calibre Sentry?
The Sentry takes the XL / MTB too. Every Calibre in our fit database takes the same cover, so there is no guesswork between models. If yours carries a rack or a rear child seat, the XL / MTB is still the right choice.
