The replacement of the 9 speed Shimano road RD with a 9 speed Shimano mountain RD is fine -- the cable pulls are the same. You'll need to re-size (i.e. put on a longer) chain for the bigger cassette though. As for the crankset swap, I think with the new cassette it isn't going to be necessary. In any case, the Sora FD-3403 (which is what you likely have) ...

It is possible. For typical mountain rims, the low limit is somewhere around 28mm. Some differences from mounting narrower tires are following: Less cushioning from tires: Smaller tires can not absorb as much shock from from curbs, cracks in the pavement, etc. On the other hand, smaller tires can be made with more flexible casing and absorb small ...

What you want for road use is slick tires -- tread and knobs are bad for road use. You have 26" (ISO 559) rims, so you need 26 x (something) tires where (something) is a number in decimal form (e.g. 1.75). Going for smaller tires will lower the bike a bit, and smaller tires have to be run at higher pressure (so you'll get less cushioning). There will also ...

No -- You've got several problems here. 10 speed mountain Shimano has different cable pull than 10 speed road Shimano (which is the same cable pull as 9 speed mountain Shimano, I believe, so if you double check this, you can drop a 9 speed Deore in). Then, you have the mountain vs road FD, which if you're using brifters, you need to use a road FD. Front ...

Do you mean this rack? On the linked page it says that the rack will fit a 700c bike. Also I see that there are two holes at the bottom (dropout) mount, that would make it easy to use something like a repair strap to raise the rack if that proves necessary. Use a bolt through both holes so that the repair strap and rack can't move under load. If you're ...

AFAIK all today's 105 and up Shimano cranksets are Hollowtech II, so when replacing your old you need to exchange the bottom bracket with bearing cups. You need to figure out what kind of bottom bracket shell you have and whether replacements even exist (only BSA68 and Italian are available). They are much better than old cranksets (easier to install, ...

The Miyata 1400a is made of aluminum. A 7 speed Shimano 105 system uses a rear spacing of 126 mm, which is smaller than the 130 mm needed for a modern 8-10 speed system. For a steel frame, its no problem to stretching the frame and get the wheel in. On an aluminum frame, you really shouldn't. That being said, people have done this at their own risk, by ...

Cable pull is the same for all mechanical caliper brakes. The things to take into account are the mounting nut and reach. Older brakes use a hex nut to hold the brake in place while newer ones use shorter bolt and countersunk nut. Most of new brakes are for recessed mounting, if your bike has traditional nut you will either need to find a brake with longer ...

There is a certain degree of compatibility, but usually it comes with a big compromise, such as having to use a flat handlebar (for your MTB shifters and brakes), smaller diameter wheels (road is 28", your MTB is likely 26"), lower gearing (pedaling on road is easier so gears are higher) or bigger than usual tires (because of your wide MTB rims). By the ...

What's the wheel size? If it's 700c, then you can get disc road/CX/gravel frame. Do mind type of bottom bracket, hub widths and seatpost diameter, though. You can fit MTB shifters and brake levers to a drop bar, but that would look funky, so probably flat bar only. For proper fit, stem might require replacement too.

Its almost always more cost effective to sell the existing bike and use the funds to buy a (used) bike you want. Its worth doing it from the perspective of learning about bikes, owning a unique piece of art/engineering "franken bike" or just a cool way to kill some spare time. Doing it because you want a road bike and only have a MTB is the wrong reason. ...

Take a look here http://www.vueltausa.com/components/chainrings.html It looks like the flat series is for single speed or old style 5 or 6 speed non indexed shifting bikes. Suggest you need the SE Plus range http://www.vueltausa.com/components/chainrings/se-plus-chainrings.html which is designed for 7 to 9 speed. It should be narrower than what you have, ...

34/50 is a standard combination, so 34/48 should work without problems. Friction shifters just make it easier to overshift and trim on the fly.
