comment Combining flat bar and aerobar: Double stem setup or alternatives?
The link is broken for me now, try sheldonbrown.com/org/thorn/index.html Maybe his Surly was using two non-quill stems, but on the Thorn the upper handlebar is on a quill stem, so you don't need any more steerer exposed than a single stem.

comment Is it safe to use a spacer that reaches above the steerer tube?
Spacers above the stem are needed to hold the stem in place while you do up the stem (assuming the top of the stem is below the top of the steerer). Once the stem is done up, then keeping the cap (and any spacers) is purely aesthetic (you really shouldn't be relying on it as backup for clamping the stem).

comment Is This Bike Worth 7K
It has an electric assist as well as gears. Somewhere hilly, it probably needs it.

comment Is This Bike Worth 7K
Looks like a bargain compared with $33000 for jamaica-gleaner.com/gleaner/20120826/business/business1.html onyourtrike.co.uk/coffee-trike is £10,999 but (IMHO) better looking. The Wheelys apparently launched for $3000, but it looks as if it's been developed since: treehugger.com/bikes/coffee-cart-cargo-bike.html If the price includes a franchise, not just the bike, then whether the business is worthwhile really is off topic, and will depend very much where you are anyway.

comment New Trek 1.5 wheels need to be trued after 2 rides, normal?
Cheap truing stands - billys.co.uk/english/… bikehacks.com/bikehacks/2012/06/… instructables.com/id/… Much more expensive than Park ($1,850) but very nice - pklie.de/truing_stand.html wheelfanatyk.com/blog/a-perfect-truing-stand

comment Is there a way to hop up onto a parallel curb?
Drivers deliberately using their vehicles to assault cyclists is a thing that happens. surrey.police.uk/news/witness-appeals/all-witness-appeals/… It's unusual, and it's unlikely that being able to hop sideways onto a curb will help you, but if a driver is already breaking the law by driving in a bike lane, "giving way" to them may be the safest option.

comment How can I tell if I have properly patched a tube? (specifically a 2" mt. bike tube)
Though a road tyre that still has a slow leak at 100psi won't necessarily show up overnight if you only inflate it that far, it should be fine for a 2" tyre.

comment Can I use cartridge bearings on my wheel hub?
Look at it another way - you say when you put new balls in, they look tighter. If it was really the cup that was worn making the balls look looser than when you first put them in, new balls would still look just as loose.

comment Can I use cartridge bearings on my wheel hub?
Seriously no - and nor have you. Think about it. It's not physically possible. Ball bearings are made to precisions of thousandths of an inch. Stretching by 1/8 of an inch to fit an extra half 1/4 ball in would wreck it. And if the cup really wore that much, it would do it every time you changed balls. A few services later, you wouldn't have space for half a extra ball, you would have space for two or three. But that doesn't happen. In reality, cones wear more than cups, they don't wear that much, and they do get pitted.

No, bearings just don't behave like that. Your experience may involve destroying hubs every thousand miles or so, but you can't wear a cup that much without having destroyed it.

comment Can I use cartridge bearings on my wheel hub?
Though if you count the ones that are there now and get a different answer left and right, that's a pretty good sign at least one of them is wrong :-)

comment Can I use cartridge bearings on my wheel hub?
If you find individual balls too fiddly, you can used caged ones. They won't roll quite as well though. e.g. amazon.co.uk/Weldtite-Caged-Precision-Wheel-Bearings/dp/…

comment Can I use cartridge bearings on my wheel hub?
Even if you have spare clean unworn balls, you should use ones bought together as a set except in an emergency. sheldonbrown.com/tooltips/hubs.html

comment Can I use cartridge bearings on my wheel hub?
"very quickly wear of the cup makes it look as if a ball is missing" - sorry, but that's just rubbish. Well maintained cups take years to wear, and the amount of wear that makes a bearing unusable is far less that the amount that would let you fit half an extra ball in. It's just that when you put the balls in and grease holds them into position, they aren't always pushed fully into the position they finally take up when you do the cones up. ("One less than you could squeeze in" is right though. e.g. madegood.org/bikes/repair/service-a-cup-and-cone-front-hub step 7)

comment Why are both Schrader and Presta valves still used on tubes?
The ones with a little bit of rubber are Woods valves, aka Dunlop valves. These days their main purpose is answering trivia questions about why some tyre repair kits still have little bits of rubber tubing. sheldonbrown.com/gloss_w.html#woods

comment Interrupter (cross) brake lever cable guide wedges?
Park recommend against wrapping over the cables all the way up to the lever - parktool.com/blog/repair-help/in-line-brake-levers-cross-levers "Wrap handlebars. However, do not attempt to bring bar tape to lever as this may stress housing (Figure 8)." (Making up a suitable wedge would avoid the risk of stressing the housing though. Now I'm tempted to make something for mine.)

comment MTB with Road crank
You can get 46t and 48t Deore chainrings. Keeping the same crank and using larger chainrings might be better and/or easier than using a road crank.
