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.

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 ...

Upgrading an older bike is typically not economical. Parts are typically not cheaper. Parts are not as available. That drivetrain is not compatible with a modern bike. Bikes have gotten better. Little faster, lighter, more comfortable, and easier to service. You can find decent to nice newer model used bikes for $400. Find someone that bought an $800 ...

This is to do with the different pull ratios employed by the different systems. In your case 10 vs 11 speed Shimano. http://blog.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/ If you look at the table in the link - it says the 10 speed levers pull less than the 11 speed levers but the rear derailleur ratios are ...

https://bike.shimano.com/en-EU/product/component/alivio-m4000/RD-M4000.html says that derailleur will handle Low sprocket_Max. 36T Low sprocket_Min. 32T ANSWER: You cannot run a 50 tooth cog with that derailleur. You might be able to use a hanger extension, but that will make the small gears even worse. Wolf Tooth's Roadlink allows up to 40 tooth,...

The combination of rings and sprockets you can use depends on the specs of the derailleurs, specifically the total capacity of both the front and rear derailleurs and the max sprocket size of the rear derailleur. Front total capacity is just the max difference in size of the small and large chainrings, measured in teeth. Rear total capacity is the max (...

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, ...

Beyond the question of finickiness of actually using the system with higher cog counts, it's a matter of whether there's enough total cable pull from the shifter in friction mode to cover the range of movement needed given the cassette used and the actuation ratio of the derailer. Here's an excellent article with the basic data you need to figure it out, ...

Looks like the new one has the same kind of saddle rails so you can remove the attachment from it and try the bare saddle rails in the suspension seatpost. It should work! Undo the two big black nuts and it should all fall off. Edit (Grigory, Criggie): The extra bits are just the clamp from an older design of seat post. So they’re not needed, but might be ...

One confusing thing here is that SRAM themselves, that I know of at least, have never made or warranted a 10 speed 11-42 1x setup. So you're not going to hear from them or their product documentation that any SRAM RD will work here. There are two questions. One is capacity, which is the total amount of slack the RD is capable of taking up. Different cage ...

Shimano lists the FD-R7000 front derailleur as compatible with the FC-5800 crankset in their products compatibility information, but the R7000 crankset wont be compatible with the old derailleur.

Shimano's most recent compatibility chart is available here. Note that these are official compatibility ratings. It is fine to exceed official specs by a bit. At the rear, you can get a 10s Tiagra cassette that has a 34t cog, but it does technically require the long cage Tiagra RD. The issue was discussed here. The short cage Tiagra RD is rated for a ...

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.

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

tldr: be sure new rotor works with metal pads or get a set of resin pads. Generally, disk brake rotors of same diameter are thought of as cross-compatible, but there are some edge cases when this might not be true: Rotor thickness might not be the same across manufacturers and disk brake calipers might be designed with thicker/thinner rotor in mind. ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

They're for full fenders. Many disc road and fitness/urban/hybrid bikes now have them here in order to completely avoid strut interference with the brake. To install the fenders neatly I've been mounting the fender, then mounting the struts sticking off into space in the general direction they'll run in from the mount, then bending one with a non-marring ...

Longer is better – it helps stop rattling if the seat post is longer than the shim and banging the seat tube, although if that happens you can always cut down the set post. As far as safe to use – as long as the shim is at least as long as the minimum seat post insertion required for the frame, in theory you are stressing the frame no ...

Yes The website for the Stages Power Meter mounted to a Shimano Dura-Ace R9100 non-drive-side crank arm says: Crank Compatibility: All Shimano Hollowtech II road cranks This also agrees with Rider_X’s comment and my own guess that they should all be compatible.

An 11-speed chain will mesh with and be driven by a ring designated 8-speed without issue, barring corner case exceptions. (There's nothing necessarily stopping manufacturers from cheating or being sloppy with keeping everything that's nominally 3/32 cross-compatible even with parts of disparate eras/types as in this example, but it's not an issue one sees ...

Derailleur will not handle that, as Criggie says in his answer. Apart from that, an 11-50 9 speed would have horrifically big jumps between gear ratios. 1x systems only really became feasible with the advent of 11 speed drive-trains, and still sacrifice ratio jumps to get a full spread of ratios to some extent. If you really want a 1x 9 speed, get a ...

I found this helpful site which explains the different types and compatibilities: Mechanical bicycle brake compatibility Types of brake levers and calipers These are the brake lever types with their amount of cable pull per full lever travel (about 20 degree angle): V-brake (also known as Direct-pull, or linear-pull), 15 mm ...

Short and easy answer - yes. Shimano compatibility charts show ST-R7000 shifters are compatible with FD-5800 front derailleur and RD-5800 rear derailleur. All Shimano road rim caliper brakes are compatible with each other. http://productinfo.shimano.com/#/com/3.7?cid=C-453&acid=C-455
