A: Rebolt Kalymnos uses titanium glue-in bolts and anchors certified to both EN 959 and UIAA 123 SCC, installed with high-quality epoxy glue. SCC is the UIAA corrosion-resistance category for bolts and anchors requiring the highest resistance to both stress corrosion cracking and general corrosion. We consider this methodology to be the current world best practice, and are committed to this approach for Kalymnos.

A: The average cost in May 2026 is €285.00 for a route with 10 bolts plus a 2-bolt anchor/lower-off. This figure covers hardware and consumables: titanium glue-in bolts, anchor set, carabiners, epoxy glue, glue nozzle, and consumables such as grinding disks, drill bits, and patching material. It does not include soft costs such as shipping, labor, equipment wear, or travel. Cost includes tax.

Material prices fluctuate frequently, and the total cost of rebolting varies based on route length, rock angle, and bolt count.

A: Kalymnos has more than 4,600 routes. Updating the island's aging hardware is a major, multi-year task. For this reason, we take a risk-based approach: we prioritize work that reduces the most risk for the most climbers. Several factors inform this:

• Hardware material: routes with 304/A2 stainless steel, unknown hardware, mixed hardware, or known problem products are prioritized ahead of routes with more modern hardware.
• Hardware age: older hardware is generally treated as higher priority, especially where there is no reliable maintenance history.
• Known issues: spinning hangers, damaged hardware, poor-condition lower-offs, corrosion, or other community-reported issues can move a route up the queue.
• Route and sector popularity: heavily climbed sectors and routes are generally prioritized over less popular ones.
• Work efficiency: where a team is already working at a sector, nearby routes may be bundled together to reduce access time, rope work, and total cost.
• Practical constraints: funding, technician availability, weather, time of year, access, route length, and the complexity of safe removal and/or replacement all affect timing.

A: If you’d like to replace any hardware on a route, please contact Rebolt Kalymnos first. If work goes ahead without coordination, we can end up with inaccurate hardware records, outdated or inappropriate material, duplicated effort and long-term maintenance issues.

A: Replacing only the lower-off can create a misleading impression that an entire route has been upgraded when it hasn't. On routes with aging hardware, the intermediate bolts may still represent the greatest risk in a leader fall. For this reason, Rebolt Kalymnos prioritizes complete route-level upgrades where practical, while still addressing urgent lower-off replacements where needed.

A: Upgrading tens of thousands of bolts across Kalymnos requires sustained funding, skilled labor, and careful record keeping.

You can support this work by:

• Donating directly to Rebolt Kalymnos.
• Reporting hardware issues directly to Rebolt Kalymnos.

Important: Please report issues directly to us, not through other channels. Reports made elsewhere may not reach the team responsible for assessing and addressing them.

You can also check our real-time Bolt Beta to see which routes have been upgraded to the Rebolt Kalymnos titanium standard.

A: Rebolt Kalymnos uses the Bolt Beta system by Rebolt The World as the primary source for route-level hardware information, issue reporting, and inspection tracking.

Bolt Beta allows climbers to:

• Find routes equipped with modern hardware, including titanium and 316/316L stainless steel
• Identify routes with older hardware
• Track reported issues and rebolting progress

The system provides a centralized, continuously updated record of hardware information for Kalymnos and helps reduce fragmented or inconsistent reporting across multiple platforms.

As with all fixed hardware information, records may be incomplete or change over time. Climbers remain responsible for assessing hardware and making their own decisions at the crag.

This FAQ section is designed to provide general information about the work and practices of Rebolt Kalymnos. It is not a guarantee that any route or anchor is safe. Climbing is inherently risky, and all climbers assume full responsibility for their own safety and decision-making. Conditions change, records may be incomplete, and climbers must assess all fixed hardware before use.
