Best suggestion AB. Hadn’t thought of that but an ideal solution.
Only downside might be the cost, bar ends are quite expensive especially compared with these cheapie band on ones:

Might be worth checking the tube diameter but I don’t think the Nitro used oversize.
Thanks @Cycleops! I think this might be the cheapest option. Just a quick question though. The ones in the link are 6speed... would that still matter? or would I need to find a 5speed one?
