How we calculate scores →About this gear
R261 is a bare carbon cylinder listed by rEvo for its equipment range. The product title calls it 2.1 litres at 300 bar, while the description says 2 litres. Its specified M18 × 1.5 neck thread is a critical purchasing detail, and the cylinder is supplied without a valve.
Consider before buying
There are unresolved official discrepancies: the product description gives 96 mm diameter and 1.4 kg, whereas the 2025 parts list describes a 100 mm diameter and does not settle the capacity difference. These are reasons to confirm the actual cylinder markings and dimensions, not to average the figures. Gas-service suitability and local filling acceptance are also configuration-specific.
Our take
Choose it only after rEvo or an authorised supplier confirms the exact cylinder version, compatible valve and unit mounting. A 300 bar listing does not establish compatibility with every rEvo valve. The R252 steel cylinder is a separate lower-pressure option with the same stated neck-thread size, not a drop-in equivalent or evidence of this carbon cylinder’s performance.
