I'm in the process of building myself a commuter for school. Nothing serious, just an old Trek i found on craigslist. Previous owner transformed it into a fixie, but I like single-speeds better.
So, I replaced the wheelset with some Velocity's with flip-flop hub, switched over to some simple platform pedals, and installed some 700cx38 tires with matching tubes.
I'm not quite done yet, I want to install a bullhorn bar, new leather-esque tape, matching leather-esque saddle, new front brake and finally, a 2-speed SRAM automatic hub with coaster brake.
My question for you is about the 2-speed hub (first gear is normal, and second is +30%):
Currently, I have a 42T chainring and a 16T cog. This puts me at a 2.625 Gear Ratio (GR), and 72.5 Gear Inches (GI).
With the 2-speed, it comes with a 19T cog. So, 1st gear would be 2.210 (GR), and 60.7 (GI) and 2nd gear would be 2.873 (GR) and ~79 (GI).
Ive been told that 70 (GI) is what most people should strive for, So would a 2 speed with an average of 70 (GI) be good? I figure 1st gear could be really easy around town, and up hills, and then when I want to gain some speed, use the 2nd gear?
oooor should I change out the rear gear and have a 1st gear GI of 70, and have a roughly 90 GI in 2nd?
What does /n/ think?

My city has become less safe for cyclists since the city council decided to make bike lanes.
The lanes are too thin, about the width of my handlebars in some sections, and put right on the side of heavy and fast traffic that goes by so close their side mirrors can knock you out.
As a result most of us daily commuters still ride in the middle of the road, even with a bike lane right beside us. Needless to say, this triggers the cager.
Is this a thing in other cities, in different countries, city councils creating makeshift unsafe bike lanes to get bikes off the main road just to accommodate car traffic?

Fuck this piece of shit right here.
I always thought of Shimano as a premium manufacturer of quality components that just work. Even when I was a kid, my dad always looked for the bikes with the Shimano components. So when I saved up to buy a road bike, I made sure to get Shimano.
First, you have the extra set up of having to choose the right cable path and putting on the little plate for the adjuster screw, but if the adjuster screw hits the braze on just right at the edge, it becomes infuriating to adjust.
But this fucking piece of shit. It's nearly impossible to set it up without getting chain rub, and Shimano fucking knows that, so they put a plastic insert on the inside to make it hard to hear chain rub. You try to have enough cable tension, and then it suddenly no longer clears the small chainring big cog combination no matter how much you unscrew the lower limit. You try to clear one extreme, and suddenly the other is rubbing.
When you finally get it set up with half a millimeter of clearance there's barely enough clearance for the chain in the big ring, and once you stand up on the pedals in 52x11, you can just hear the scraping. Scrape, scrape, scrape. Try to set up this shit up so it doesn't rub in 52x11 and every other gear combination starts rubbing trim or not.
Then the cage is so fucking narrow that you have to spend all your time in the small ring trimming, trying to second guess if you have rub because of the plastic insert, and it just barely clears.

Just got a beatup '99 K2 Zed X. Planning to turn it into a commuter. Any tips/suggestions?
Non-stock tires and a few other minor changes. The logic behind getting a MTB is that I ride kinda hard sometimes and want to be able to go offroad every now and then. (Maybe do some local trails.) There are some slopes here and there in my town in the urban areas too. Also it got good reviews online & I'm poor and got it really cheap off craigslist. (Checked my local registry for the S/N, wasn't registered.)
Things I plan on doing:
- replacing the "smart fork" with a suspension-corrected static fork
> weighs less, I'll learn better riding habits, conserve more energy, faster, no maintenance, no bullshit gimmicks, cheap
- replacing the front wheel with one that can take a rim brake and get a v-brake instead
> the disc brake looks cool though. maybe since I'm mostly riding in the city it's worth it to maintain?
- cleaning & oiling the drivetrain. It seems alright. I should be able to tell if I need a new chain after more riding, and the derailleurs may need some adjustments.
- transferring the saddle from my old bike
- transferring the rear rack from my old bike
What am I missing?
