What Bike Do You Need for Himalayan Cycling?
A gravel bike is the optimal choice for Himalayan cycling. Road surfaces range from smooth tarmac to loose gravel, broken concrete, and stream crossings — often within a single day. Key specifications:
| Specification | Recommended | Why |
|---|---|---|
| Tyre clearance | 40–45mm minimum | Unpaved sections, loose gravel, stream crossings |
| Gear ratio | 1:1 minimum (34/34 or lower) | Sustained 8-15% gradients at altitude with loaded panniers |
| Brakes | Hydraulic disc | Steep descents (up to 20km continuous), wet conditions, loaded weight |
| Frame mounts | 3+ bottle cage + frame/fork bag mounts | Carrying capacity for remote sections with no water/supplies |
| Frame material | Steel or aluminium preferred over carbon | Repairability in remote locations. Carbon cannot be welded if damaged |

How Do You Prevent Altitude Sickness?
Altitude sickness (Acute Mountain Sickness / AMS) is the single biggest risk for Himalayan cyclists. Symptoms begin above 3,500m — headache, nausea, dizziness, fatigue, loss of appetite. Prevention is about acclimatisation pace, not fitness level — even elite athletes get AMS if they ascend too quickly.
| Altitude | Risk Level | Acclimatisation Strategy |
|---|---|---|
| Below 2,500m | Minimal | Normal riding. Hydrate well. |
| 2,500–3,500m | Moderate | Limit daily elevation gain to 500m. Rest day every 3rd day. |
| 3,500–4,500m | High | Limit daily gain to 300-400m. Acclimatise 1-2 days at 3,500m before ascending. Sleep lower than highest point reached. |
| Above 4,500m | Very High | Pass crossings only — do not camp above 4,500m if possible. Descend to sleep. Carry Diamox (consult doctor before trip). |
Critical rule: If symptoms worsen despite rest, descend immediately. AMS can progress to HACE (High Altitude Cerebral Edema) or HAPE (High Altitude Pulmonary Edema) — both are life-threatening emergencies. Never ascend with AMS symptoms.
