Always handy to know a bike shop is within the area. Framed bikes is on the main street through Llanberis. The owner said there is a two to three week wait for work, but I got the feeling he would assist riders passing through

Maesgwm is also known as Telegraph Valley. The trail is gravel and well-made, brilliant to ride and much quieter than the main Llanberis path. It makes a great loop from Llanberis, using a section of the Ranger. Rideable in both directions.
