I hired a very light Cannondale Super Six with an Ultegra groupset from
Free-Motion
bike hire while in Gran Canaria earlier this month. Got to climb the
local mountain four times and you can see the ride profile
here.
To say I'm not the world's greatest climber would be an understatement,
so I was pleased enough to make it to the top. The ride starts with a
very gentle uphill alongside the valley's river-bed and then you come to
this sign:
From there on it's a bit of a challenge for those of us who aren't Jon Tiernan-Locke, but it's worth it for the views along the way and the feeling of achievement when you reach the top. I'm sure some of the slopes are steeper than 12% as they seemed more severe than that steep one in Richmond Park. The climb up Ditchling Beacon outside Brighton is about 700ft whereas this is around 1300ft so I wasn't surprised when the guy at Free-Motion said quite a few people had returned the bike and asked for a different cassette to help with the climb. I would have as well if I'd realised it was 11-25 (I have a hill friendly 12-29 on my Ribble).
The shifting, courtesy of Shimano Ultegra, was extremely smooth.
