Which Bibs?

Kirth, order some from Prendas http://www.prendas.co.uk/list.asp?ID=5&typ=typ
they are good and cheep and the santini bibs are awesome.
The £40-odd bibs I got from Shutt last year, weren't cutting the mustard over 100km, so I splashed out on the Santini Edge from Prendas, more because I have come to trust them, than any particular recommendation for the shorts.

Awesomely comfortable and the longer leg is nice too. The pad is just amazing!
