First half (of the half) has a couple of longish inclines not too steep but then second half has a delicious long downhill for a couple of miles with a short sharp incline right at finish
It doesn't bump or slosh if you follow all the advice here ie no air and tighten up every now and then...but I can't seem to get the valve thingie working well... flow seems quite irregular....sometimes ok then can't get anything however hard I suck BTW should you suck, or what... bit confused
