Silly newbie question(5 posts)

As a long time mtn biker building up my first road bike I ran into a little question here. What are those spring loaded screws in the rear dropouts supposed to do? Observation- it seems like the rear wheel is not fully seated in the dropouts because of the interference from these screws.

Thanks in advance

You don't see them much anymore. Back before the mid 80's, road bikes had horizontal dropouts. The screws were used to center the rear wheel. Newer road bikes have vertical dropouts so they're not needed.

As long as your skewer is getting a full bite above and below all should be fine. You can use the screws to tweak your wheel base a centimeter or two depending on the drop out. (move forward for sharper handling or back for more stability) One thing to note: Make sure those skewers are very tight, on horizontal drop outs it's easier to torque the wheel out of alignment when stepping hard on the pedals (usually from a start). The wheel can pitch into to the left stay and bring you to a quick halt. Nothing to be concerned about tho, as long as you keep the skewers nice and tight.

Does it hurt to completely remove them? Just curious, this would alter the wheelbase even more I suppose.

Vertical dropouts not only eliminated wheelbase adjustment, They helped by getting the derailleur in the best place for indexed shifting. Get a wheel too far back in horizontal dropouts and your indexing could get cranky.
