>>954971>You'd need to buy a new bar, bartape, brifters and brakesAre you sure that you need new brakes?
>>954812>Clipless pedals and race fit are not necessary aspects of a road bike.That's certainly true and pedals/shoes are very easy to upgrade.
If anon buys some Arnie-style 70s-90s steel road bike then sure, that's a decent thing to commute on if the roads are good. Sheldon famously took one mountain biking in Europe but that's Sheldon. For shit roads and a commute that involves trails through parks etc, a hybrid would be more practical.
