What the BOSS-X takes
The BOSS-X takes a 3-piece set: bowstring and two cables. A crossbow's string and cables are short and heavily loaded, so they are built in thread chosen for that job rather than in the blend a compound uses.
| Piece | Sold separately |
|---|---|
| Bowstring (Crossbow main string) | $54.99 |
| Cable (Crossbow buss cable) | $49.99 |
| Cable (Crossbow buss cable) | $49.99 |
| Complete set | $139.99 |
Buying the set saves $14.98 against the 3 pieces individually.
Materials and colours
Built in BCY DynaFLIGHT 97 (100% SK75 Dyneema), what our bench chooses for a crossbow, or BCY Mercury 2. Pick your material and colours in the builder; it only offers what each one is stocked in, and the string draws itself on screen before you order.
Ordering
Every set is built to order. The current build time is shown in the builder before you pay. Free shipping anywhere in Canada over $50, or collect it at Tyee Marine & Outdoors in Campbell River or Tyee Archery & Outdoors in Kamloops.
