comment Is it possible to measure your sit bones at home?
I should have quantified that my coffee table, if it were a bike, would be categorized as a low rider...

comment Bike lock for a Mountain bike with easily removable wheels
@gcb how is this any different than hammering the lock against the bike rack? In any case, I'll take my chances. Whenever possible I always lock my bike next to one that is nicer and less securely locked.

comment Can I use an “8 speed compatible” crank such as Shimano FC-2303 with a 7 speed Shimano MF-HG37 freewheel?
If you're on a budget, I would try making your existing front derailer work. You would need to move it upwards slightly on the seat tube and get it to clear the max chainring by about 1mm. Then simply test ride and see if works to your liking, if not, get a new one.

comment Bike Polish for Carbon Frames
I'm convinced the FinishLine bike polish is really just a can of furniture polish with a FinishLine label. It smells just like generic furniture polish, sprays out of the can like furniture polish, looks like furniture polish, etc. I really prefer Motorex Bike Shine.

comment If not Kona Asphalt Commuter then what?
I like to differentiate between "hybrid" and "commuter". To me the Kona Dew series is more commuter than hybrid. I take hybrid to mean something more upright, potentially with a front suspension/seat suspension and generally a bike less performance oriented and more comfort oriented.

In winter conditions you should not be using a dry lube.

comment What tools do I need to disassemble and re-assemble an 80's road bicycle
An 80's bike will likely have more metric nuts than metric hex. You'll probably want an 8/9/10 mm wrench set. There are also specialized tools for the headset and bottom bracket. I have a listing of bicycle specific tools here: 802bikeguy.com/bicycle-tools

comment Does a hybrid truely have a wider tire or does a mountain have a wider tire?
I really wish all these fuzzy measurements like 26" or 700c would just go away and we could all start using real measurements like the ISO diameter. The ISO diameter is a REAL measurement from bead seat to bead seat in millimeters. Modern 26" wheels are ISO 559mm. 700c (and 29er, yes, it's the same size as 700c) are ISO 622mm. This is the only real measurement of a tire. Almost all tires have this on the sidewall in a XX-YYY or YYY-XX format where YYY is the ISO diameter. If you want to read more about ISO read this: sheldonbrown.com/tire-sizing.html#decimal

comment Any thoughts on spoke lights?
They are front/rear lighting. I don't know of any non battery side lights. I have some Monkeylectric M210 lights on order. monkeylectric.com/m210.htm

comment Can I use normal grease for a car on the surface of carbon bike?
Where did I mention anything about motorcycle grease? I have in fact, repacked more than a few hubs with an automotive wheel bearing grease, a Valvoline Synthetic Blend, specifically. The axle when spun feels no different than had I used bicycle specific grease, and the wheels spin fine with no noticeable resistance.

comment Will it cause problems if I use components from different series?
Of course Shimano doesn't want you mixing components because it's bad for their bottom line and stating they're incompatible gives their warranty/tech department an out when something goes wrong. Same goes for your local shop, "look, chart right here says incompatible, sorry dude". In real world practice you'd likely have no issues. At some point Shimano even published a "B" cable routing position so you could use an N speed cassette with an N+1 speed shifter: sheldonbrown.com/derailer-adjustment.html#alternate

comment Will it cause problems if I use components from different series?
Technically speaking your are correct in what is probably very minor width differences. However, I used an "8 speed" XT rear derailer with an 8, 9 and 10 speed shifter/chain/cassette before I trashed it and have now switched to a SRAM X9 "10 speed" rear derailer. The XT performed perfectly fine with an 8, 9 and 10 speed shifter/chain/cassette. The 10 speed chain had no problem mating with the teeth of the "8 speed" pulley wheels. The travel range of an 8/9 or 10 speed derailer should be almost exactly the same. Pulley wheels on most mid to high end derailers are all 11T.

Park Polylube 1000 and White Lightning Crystal Grease are just as thick as automotive wheel bearing grease.

Grease is common on bicycles, in headsets, bottom brackets, hubs, seatposts (to prevent them from getting stuck), etc.

I've repacked many a hub with automotive wheel bearing grease. For mating carbon surfaces you should use carbon paste, this is a grease with microparticles. It provides a grip between the carbon surfaces. For bearings, grease as normal.

Rear derailers are not speed specific. They are only marketed as such. 8, 9 and 10 speed cassettes are almost exactly the same width (within 1 mm). As far as front derailers and cranks go, the difference is negligible. The cage on a 10 speed front derailer may be slightly narrower than a 9 speed. The cable pull ratio is the same. The amount the derailer moves is determined by the shifter, not the derailer (assuming all road or all mtn components, you shouldn't mix a road shifter with a front mtn derailer or vice versa). I doubt OP would have issues.

comment Do tube protectors increase rolling resistance or just add weight?
Excellent, thank you for taking the initiative. 7x was what I heard early on in my shop days. This doesn't eliminate the fact, however, that putting $ into a lighter wheelset instead of components is still a good idea.
