After seeing sales of their out-of-print cycling editions on eBay for as much as $139, Lonely Planet has reintroduced is cycling travel guidebook series.
The first three guides are available now with updated routes, elevation info, GPS-friendly maps and recommendations for bicycle friendly restaurants for France, Italy and Britain.  Cover price is $24.99, but they’re available on Amazon.com for $16.49, which also has most of the older editions, too.
