TVB Tech is proud to partner with NSR Racing to bring high end damper upgrades for RockShox suspension products, helping you to improve performance on the trail.
NSR-Racing is a Tasmania based suspension tuning centre run by ex World Cup mechanic Nigel Reeve. Nigel has worked with numerous world cup racers including Stevie Smith, Troy Brosnan and Mark Wallace. The numbers speak for themselves. Since 2013 in World Cup Downhill Nigel has helped riders achieve seven World Cup victories, 28 podiums, and a further 22 top ten finishes. Meanwhile with the Enduro athletes he's supported we’ve seen seven wins, 13 podium places and a further 40 top ten finishes.


NSR-Racing is the result of over 15 years of technical experience working at the elite level of mountain bike racing. Bringing together a wealth of technical knowledge covering suspension engineering and tuning, bike geometry, data analysis, and race engineering.
NSR-Racing’s high performance damper tuning is based on their D Arc concept. The goal is to provide a firm, well supported ride that enhances grip and generates rider confidence.
- More active feel
- More support - allowing lower spring rates and air pressures leading to:
- Increased grip & comfort
- Better response to rider inputs and helping to create a positive feedback loop of rider confidence.
