Not challenging you but I think F1 uses pneumatic springs and an overhead cam. They arent fully pneumatic control like in the video.

Hourly Weather Observations (NWS)

Current Summit Forecast



A strong low over the Canadian Maritimes will bring continued summit fog and upslope snow showers through the day. Additionally, the low will continue to keep winds elevated with gusts reaching well over 100 mph today, tonight, and into early Thursday. Cold air will continue to flow in from the northwest keeping temperatures well below normal for mid-March. The high winds and cold temperatures will increase the risk of frostbite on exposed skin for most of the forecast period. Therefore, a wind chill warning will remain in place until early Friday morning. With severe conditions today through Thursday morning, hiking above tree line will be extremely risky. As a result of the high winds, summit staff will be unable to assist in any search and rescue should they arise. All efforts will be coming from below and will be slow going or possible postponed until safer conditions return for search parties. Hikers should be mindful that a single injury may keep them on the mountain for an extended period of time and will potentially put several lives at risk, not just their own in the coming days. Thursday afternoon will finally see gradually improving conditions as high pressure builds and with it, drier air. This drier air mass will move in from the west and allow fair skies to return over the summits for the afternoon and overnight hours. Thursday night into Friday, winds will finally dampen as the high starts to crest in and a light return flow allows temperatures to slowly start to rebound to more seasonable readings.
