Thank you for both posts. What's the rationale for lighter riders avoiding wider tires? Too much air volume per pound of weight?
Since you have ridden Shamals, do you think the narrower rim (17c) makes it any less desirable than the wider alloy competition (HED/Ardennies, Easton/EA90, etc.) which run closer to 18c-20c?
