105 5800 DR + 30 dollar chain........ I don't think so. Unless you know somewhere to get cranks cheap. Those are new prices. Personally, I wouldn't buy any used.
edit... yeah I'm probably being a little harsh, and the OP should consider if they need the low gearing that would give.
For myself, I just think it might be too low a gearing, depending on what part of Maine the OP is riding in. As well, when going downhill, I like to pedal and have a little resistance even though I might not be adding to the speed of just coasting.
Yeah, I thought I had seen the GRX at around $149 or so, it’s up around $225 As well, a 105 level 11spd. Cassette is nearer to $50, F derailer also near $50-$60 on a few Google look ups, chain around $20. But the OP indicates he wants speed so maybe going to a 48 isn’t the solution. I was thinking that a low of 30/31 ring would help deal with the hills.
