I Bike Fridayed for about... 2 weeks in southern Portugal last year.
rough outline of the route is attached.
I missed the far SW corner though, which seems to include Salema.
Roads and routes were a mixed bag as I recall. at times I was ready to scream at the Ministry of Tourism (and Transportation) the roads were so bad and dangerous. though maybe I just route planned poorly.

Let me know if I can shed any light.

How wide and what type of tire to expand the conditions for my Pocket Rocket?

Rob Macleod <mac...@sci.utah.edu>: Feb 10 04:43AM Hi Friends,   I have a Pocket Rocket Pro from 2010 that I love and drag all over the place but I need to explore some wider tires, perhaps wheels.   The current wheels are labelled Velocity A23 and I cannot see any other specs from the outside (see photos below). I usually ride Schwalbe 20 x 1 1/8“ tires, so clearly road tires. I sometimes go onto gravel paths, but the ride is not fun.   What are my options for some wider, more forgiving tires as I prepare for a trip to Portugal in May, where our sources claim a lot of the good riding is on gravel paths? I am still researching the bike routes in the very southern part of the country around Salema so pointers would be much appreciated. But the main question is about making the bike a little more flexible.   Thanks in advance, Rob For more Bike Friday adventure shots, you can visit my bike webpage<https://www.sci.utah.edu/~macleod/bike/>. Most recent was a wet, cold ride up Alpe d’Huez.   [IMG_1778.jpeg]

John Thurston <y...@thurstons.us>: Feb 09 08:05PM -0900 Rob, check the archives for June of 2025. We had a discussion of wider 451mm BSD (the size on your Pocket Rocket) tires. One I recall coming up was the Tioga PowerBlock. Tioga calls the 451mm rim size "OS2". I really like the PowerBlock. If they will fit into your frame (and under your brakes), they are worth trying.   Regarding your rim. The A23 is (IMHO) a solid performer. I have it in several sizes. I use it with tires up to 50mm in width. Those wide tires are a little "light bulby" on that rim, but they get the job done. Be aware that as you increase the width of your tires, the expansive-stress you put on your rim increases. So when you "go wide", you also need to run lower tire pressures.   John Thurston Juneau, Alaska   On 2/9/2026 7:43 PM, Rob Macleod wrote:

  of the 20" wheel , 406 offers greater variety  of tire widths than 549...

N+ 1, solves that issue  , get another bike to satisfy your wide tire trend desires...
