Mauna Kea... also a race up there on Aug 11th .
Hi Mike , i already heard about the "Sea To Stars"-race , but then we would have to stay for 3 weks (acclimatisation...) and both me and my friend don't have so much time to spend ...
You need a mountain bike for. I rode a 38 x 27...
I think. it's narrow in places, twisty, sometimes not the best road surface but overall pretty good. You can only get to about 10,000ft on a road bike.. after that it's a gravel road that you need a mountain bike for. I rode a 38 x 27...
I have 39x29 (Campy) ...
Let me know if you have questions and I'll try to answer.
Thanks for your offer , i'm sure that i have some more questions in the future .
Put some 25mm tires on the road bike and go for it on the gravel part of Mauna Kea. Haven't seen the road in years but I know it's been done a few times over the years on a road bike. There are pictures of some euro guy doing it I saw somewhere on the internet.
As far as bike selection on Mauna Kea. The mountain bike suggestion/requirement for above 10K feet on Mauna Kea is not really due to road surface, it is due to steepness some sections greater than 20%. Not bad by themselves but after 10+k of climbing very tough. The race to the actual summit has folks changing bikes at pavements end. You could probably run cross tires or some other 25c or larger variant on a road bike but an MTB would be vastly more enjoyable.
Unfortunately my chainstays are very short so probably there's not enough space between tire and seatstay and i can only use 23mm-tires.
Thanks for all the answers !!!
