This link says the frame has the necessary cable stops for a front shifter and front derailleur. You'll need a new crankset (you can find 9 speed+ triples or doubles pretty cheap these days). This may require a new bottom bracket as well, depending on which crankset you choose (I'd guess whats on there is just standard square taper) and the chainline ...

Getting though all the hype and testosterone - Compact cranks allow a smaller small chain ring as they have a smaller BCD. Modern tech means you can have a wider gap between chain rings, giving larger spread. This means modern compact cranks with wide range 11 or 12 speed cassettes can get the same gear range and stepping as a triple 7 or 8 speed with just ...

I have an 8 speed hybrid bike (due to neck surgery, I had to switch to an upright riding style from a drop handle) that I want to upgrade the crank. Currently I have a hybrid triple crank with the large chain ring being 48T. I want to change to a compact double with a 50T to gain a little extra speed. The front derailleur is a shimano C101. My cassette ...

Returned to this this morning, and have found that the high limit screw could be let out a bit more, and now that is done the chain reaches the large sprocket just fine! Apologies for being dense! I am now finding that I can index it fine for going up from the low sprocket, or coming down from the large sprocket, but not both, but I'll work on that....

The issue here is going to be clearance between the frame and chain in the extreme gears. The smaller chainring moves the chain down towards the front crossmember, but from the images I've found online I don't think that will be a problem. The drop from 30T to 24T alone gives you a 19" bottom gear. In order for the rear derailleur to keep working you need to ...

In case of road bikes, back in 2012 (when question was asked), there was simply no option. There was some cyclocross setup but didn't really sell in this market. Road single chainring group set only available in 2015 by SRAM. I just switched to their 1x11 (48t 11-36) from 2x10 (50/36 11-26). Hardly miss the closer ratio of the 2x10 or top speed, which ...

10 speed works with 10 speed. You will be fine with the chain you have. The major difference being that the one that is made for 3x10 will be a couple links longer generally. Usually this is designated by a number such as 116L where the L stands for links. Width wise you should be fine with any 10 speed chain. 10sp chains are slightly more narrow than a 9sp ...

I have a 3x8 converted to 1x8, and the trick is to put a 48 tooth big ring with a road cassette. That is even in gear size increases otherwise it wont work. The chainring being 48t holds the chain well as over half its diameter is biting the chain. The only time I have a problem is if the chain is worn and slack, and I do a big jump in 8. The chain has ...

They can be serviced, but various techniques were used to get them to work. After you clean the parts and lubricate only where appropriate, you have to be very careful to put them back together exactly the way they were built. Which shifters do you have - can you furnish a picture?

There are a number of factors to consider. For another question, I looked up the specs. on a specific Shimano derailleur. It listed min and max values for both the largest and smallest rear cog as well as a total range. Of course, you may be able to make it work outside that range. The bolt circle on your crank will limit he range of gears you can use. On ...

There's a short answer to your question and a longer fuller answer. The short answer is that a common standard for road cranksets is 130mm BCD (bolt circle diameter). The smallest inner chainring you can use with 130 BCD is a 39 (as Kibbee has said, technically you can get a 38 tooth 130 BCD chainring although that doesn't leave much metal between the lower ...

One limitation is your rear derailleur cage length. Typical are short (road), medium and long (mtb). If the cage isn't long enough it can't handle a cassette with wide range. For example a short cage might be able to handle 12-26 cassette, but for 11-30 you'll need a long one. It also depends on range of chainring. Wether it is the range in chainrings, ...

For some people who want to spend the money and time customizing a sweet vintage ride, I'd say go for it! It's certainly a fun experience. You don't need a new wheel or hub if you're running freewheel. Index shifting works fine with freewheel. What I did with my 6spd was keep the friction shifters for the front and install a SRAM x9 trigger shifter next ...

As an addendum to other answers, this was happening to me (not ghost shifting but the chain jumping forward). This started on a new chain, so I changed the cassette. It still happened. A test ride demonstrated that it only jumped in the middle chainring (by far the most used) even though it didn't look much more worn than the other rings. So in this case ...
