No you will not be able to use your 700x23c tire on a 650c rim. The bead seat diameter of 700c rims is 622mm, this will also be the bead diameter of the your 700x23c tire. The bead seat diameter of a 650c rim is 571mm (see Velocity's Spec section). Your 700x23c tire will be 51mm too wide.

No. Older bicycles are no harder to work on than modern bicycles provided you have specialized knowledge regarding older standards, possibly specialized tools and the ability to obtain parts designed for older standards. Generally a bicycle built now will likely conform to a set of standards that are common and in place now. If you bought a bike today, ...

Look Keo 2 and Look Keo are Look's current/previous range and they are compatible with each other. Look Delta are Look's earlier range. I'm afraid they are not compatible with Keo's or Keo 2's SPD-SL are Shimano's version of road pedals. These aren't compatible with Look products, (neither therefore are Look products compatible with them). Checking out ...

One thing to look out for is the size of the drop from the bolt securing the brake to the frame, and the brake blocks, to ensure the new brakes will fit in such a way that the blocks line up with the rims. Probably if you have a newish bike, then any new brakes you buy will be of the same dimension as new brakes. But it's worth making sure they'll fit - ...

It is relatively simple to find parts to fit old bikes. Things have changed a lot but there are still enough old bikes out there that you will not have a difficult time getting replacement chains, cogsets, derailers, wheels, bottom brackets, wheel bearings, seat posts, stems, headsets, or anything else. Any gaps in what is available can likely be filled by a ...

No. The bead seat diameter (inner diameter) is different by 8 mm. You cannot shrink a steel or Kevlar bead by 8mm, as they are designed not to stretch or shrink (otherwise a clincher tire will roll off the rim in a corner). You can try but the tube will burst out from the extra space. The tire bead is what interfaces with the rim.

Most BMX Levers are "Standard Pull", which means they have the shorter pull and are typically paired with road bike brakes (caliper, cantilever, mini-v, or road disc). Mountain bike brakes (like v-brakes, or mtb disc) typically pair with "long pull" levers, which pull more cable. This is also known as "linear pull" So, if you use a BMX lever with V-Brakes ...

Yes, they all work together. Only exception is all mini V-brakes. They are not compatible with standard V-brakes.

The Deore XT is a mountain bike derailleur and as such has is long cage dérailleur. Long cage dérailleurs can run larger cassettes for a larger gearing range (at the cost of larger jumps between gears). I don't know what the Shimano product selection was like in 1999, but you can now get Shimano 105 as either long or short cage depending on your set up (see ...

You would need a new fork in the front to add v-brake bosses and the frame does not support this either. I don't think it's worth the effort on this bike. It's sure not going to be easy without replacing both fork and frame. I think for your situation, what may be a better solution is to switch to Mechanical Disc Brakes. They are much more field serviceable ...

They make slick tires for mountain bikes used as commuters (and fat slick tires which the air provides a lot of cushioning). Some examples are Schwalbe's fat franks or big apple's (these are more baloonbike) or Marathons . Thinner doesn't necessarily mean more comfortable - in fact, the smaller the tire, the less comfortable it will typically be (this is a ...

The internal width is obviously one important feature. But for indexed shifting the ring has a pattern embossed on the side facing the smaller ring that catches the pins of the chain when shifting. The combo of the embossing depth/pattern and the ring-to-ring spacing affects what width chain (and brand chain) will work best with the ring. I've no idea ...

As an owner of both 650c and 700c-wheeled bikes will happily share my thoughts. First of all, 650c wheels are lighter and obviously smaller which makes the whole ride more dynamic which can improve your maneuverability. On the other hand, 650c wheels are prone to sliding on stones or corners so you must be more careful when riding. 650c wheels spin faster ...

As long as your choosing a 9 speed Shimano shifter for the rear and triple shifter for the front you'll be fine. That's basically everything in the Deore lineup, as long as it's 9 speed. Obviously you'll want to stay away from 10 speed shifters and dont try to mix and match Shimano derailleurs and SRAM shifters or vice versa. Though you didn't ask this, what ...

The website has drawings that show roadbike cable ends.

The short answer is yes (with apologies to jimrings). The long answer is that your choice is very limited (and depends on your definition of road tyre - do you mean road-bike tyre or road-use tyre)?. You'll need to look at http://sheldonbrown.com/tire-sizing.html#width or similar for what widths are compatible, and for urban riding (debris) or light ...

My understanding is that the chain pins for Shimano 10-speed chains are 6.0mm in length and the pins for the 11-speed chains are 5.8mm in length. That is pretty close, but I wouldn't chance it. I also don't know for sure if the pin diameter is the same and I don't have an 11-speed pin to measure. A simple google search turns up many places where you can ...

Those wheels come either with a Campagonolo compatible freehub; or a Shimano/SRAM compatible freehub. If you buy the one for Shimano/SRAM (as of this writing, out of stock in Wiggle), you'll be able to use your existing cassette. To quote @PeteH: "The 9-speed Shimano cassette that you already have, the total height of it is the same as the total ...

Usually racing front derailleurs like an arabesque will not allow the extra tolerance for a third ring. With that being said, the only way to know for sure is to try it. One thing to keep in mind is that the spindle length on your bottom bracket affects this as well. While your derailleur may have the extra tolerance to fudge it in some cases, if your ...

I think it all depends on the use you are going to give the bike. I've owned nothing but older bikes (road) since I resumed cycling around 2006, mostly for commuting and occasional longer rides (on the lines of 5.000 km / year) and everything has been ok. What I would do is try and find some old bike that works fine, and not get into the upgrade thing; if ...

Unfortunately, You can't use 10 speed shimano road brifters with 10-speed dyna-sys mountain bike drivetrains. They just have different cable pull ratios. Your limited to a few options if you want to run drop bars with 10-speed shimano: Mount your existing MTB trigger shift on your drop bars. This means you have to take your hands off the hoods and drops to ...

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) ...

SRAM Cassettes are compatible with Shimano Cassettes, but a cassette and a freewheel are different components. You will not be able to use the SRAM Cassette to replace your Shimano Freewheel. You will need to replace your freewheel with a freewheel. The difference between a cassette and a freewheel is that a cassette is just a bunch of cogs that slides ...

You can use the chainring, but each brand (Shimano, SRAM, etc...) aligns the shifting ramps and pins to work best with their own brands inner rings. So the indexed shifting will not be as fast/smooth as when you would use the same brand of rings together. Inner rings frequently have individual teeth shaped so that the chain will lift off and drop down ...

You mention a number of manufacturers there, but to be honest it's not so much the bike manufacturers you need to think about (there is no "standard frame"), its the manufacturers of the components - the groupset - which fit onto the frame. The key players there are Shimano, SRAM and (in some places, for road bikes only), Campagnolo. These companies are ...

The front derailleur doesn't care what the rear derailleur is and vice versa. The front derailleur is matched with the front chainring sizes, number of chainrings, mounting type of the front derailleur (a property of the frame) and the front shifter. The rear derailleur is matched to the shifter (for indexing; the shifter is matched to the cassette), and ...

Yes, this does. Another option is to re-thread the cranks if you take it to the right bike shop, and then install a standard pedal.

According to http://dahon.com/mainnav/folding-bikes/single-view/bike/speed_p8-1.html your bike has direct pull (a.k.a V-brakes). Your brake shoes should have threaded studs with spherical washers. There isn't really a point in getting a set with a holder given how often brakes on a folder would have to be replaced and the price difference, but Kool Stop does ...

The short answer is no. Now for the long answer... Mountain bike and road bike wheels are different diameters and use tires that are different diameters. Specifically, mountain bikes use 26" tires and road tires use the ridiculously meaningless 700c sizing. I won't get into what these sizes mean here, but you can find more info on this site or, if you ...
