i noticed some wobble on my saddle last month and it was getting worse, so a week before setting off, i've bought a new seatpost...
it's incredible how much less effort i need to put in on my commute now... although having to resist the urge to cane it now that the same amount of effort that i used to put in just pushes me further...
also, got bullhorns last weekend. going up hills is so much easier on my mtb now. can't wait to tackle the 50 miles. bring it on!
