Hill Friendly Gearing Options Campi Nuovo Record Derailleur

Hi all,

I've been really enjoying riding my early 70's Raleigh International. The only thing is, the hills are killing me. It's frustrating and embarrassing watching tourists on rental bikes out do me on the hills around here. Knowing how difficult it is to climb is holding me back from enjoying some great routes. Therefore, I thought I would get some recommendations from the forum experts here.

I would like to stay as original as possible but the ability to climb hills is more important. What changes can I make to make this a more hill friendly bike? While I'm at it, I'm considering swapping out my pedals as well. Can anyone recommend clip in pedals that can also be used with regular shoes when I don't want to utilize the clip? For the pedals, I'd prefer something that also looks period correct if possible.

Thank you all in advance!

You could put a large cage on the RD and it would be possible to run a 32 tooth large cog freewheel. If you want to go further, you could convert your crank to a triple or install an IRD Defiant Compact crank. The IRD looks very similar to Campy Record cranks but is able to use a much smaller chain rings (50-34t).

How big is the freewheel you are running? What sort of crank are you running?

Soma in San Francisco sells long cage derailleur cage plates for a campy RD; that will help since you can run a freewheel as big as a 32.

I used to make long cages for NR derailleurs and a few people around still have them. I think I still have a few floating around in my tool box but the threads need to be tapped for the lower pivot bolt. Otherwise IRD and another company make them for about $40. You could also pick up a triplelizer from Jon Vara who's a member here.

four of my five campy record rd's can pull the chain up to their 28t rear cogs. (the fifth has only a 25t big cog.) they all have 144bcd cranks, which limit the low gearing up front to a 42t ring. i'd probably look at a smaller bcd crankset if i were to tackle the cascades, 'cause i don't like long cages.

If it were me, I'd do a tripilizer with the smallest possible chainring (24T?) and a 28T cog freewheel (have pastorbob or another "forum freewheel fiddler" make it). This will give you a less than 1:1 ratio, which is sufficient unless you are riding with luggage. It will look pretty original too.

I would not worry about derailleur capacity. Just stay out of small-small.

There are pedals that are standard cage on one side, SPD on the other. Shimano makes one, Wellgo makes a near copy.

Triplelize the cranks, long cage the RD, and build a monster range ultra spaced 6 speed freewheel (16-20-25-30-34-38). That's what I did.



P.S. @top506 is running a weany freewheel! He'll have to stand to get up those little bumps he has in Maine!

Soma's "Nuova Retro" cage will allow your Nuovo Record or Super Record derailleur to handle up to a 32T cog and 38T of wrap. The long cage doesn't make the derailleur shift any better, but it's not too bad if you're already accustomed to the vintage Campy derailleurs.

The cheapest way would be a Soma cage and a big 32t or 34t freewheel. That should get you up most hills just fine if you're not carrying a heavy load. If that doesn't do it then start looking around for wide-range crank options, although on a Campy crank it will be expensive and you'll still need the long rear cage.

The capacity of your NR derailleur is 26T and you should never, ever try to go beyond that. Otherwise you'll asplode the derailleur and consign your soul to eternal torment.

Just kidding.

I'm currently running my only Nuovo Record (standard short-cage model) equipped bike with a 30T cog and it works easy-peasy, no muss, no fuss, shifts great even on the old school Suntour Perfect cogset. 14-30 six speed. Doesn't even need to have the axle all the way back in the dropouts. Small/small combo works fine but large/large is no-go territory with the current chain length. Large/large would be OK if I added a link pair, but it's a moot point since I never use large/large (or small/small, for that matter.) I briefly ran a 7-speed wheel on this bike with a 32T max cog and that was pretty much maxed out. Chain length is critical, the length of your derailleur hanger is important, as is (usually) the axle location in the dropouts. Those factors may make your NR/Raleigh bike accept a larger or smaller max cog than my bike will accept.

I wouldn't be surprised if your NR on your Raleigh handled a 30T cog just as easily as mine, provided you get the chain length correct. Although, that may not be enough extra capacity to get you up the hills. That depends on you. And the hills.

As shown; mine set up with the Suntour 14-30T freewheel, short cage NR derailleur:

I'm running a TA 52/38 crank and 14-28 freewheel on my Motebecane Grand Record, with a NR derailleur. No problems, and plenty low for me.

Consider the following:

For pedals > Shimano PD-M324 chrome cage platform one side, flip to other for SPD

My lowest gear for a 1972 Motobecane with circa '72 Campy N.Record derailleurs (stock no cage mod) is a 28t cog and 42t chainring. I can also cross all gears big to big 52t, even though exceeding chain wrap factory specs. Piece of cake climbing.

I've heard some people drill and tap the Campy Strada cranks for triples.

I've seen notes on doing it somewhere on the web.

my Bianchi

I have started riding a bike I bought a few years ago from my nephew. It's a 85-86 Bianchi Nuova Alloro with a 62 cm seat post. That's why I bought it, it was the first bike I had seen that might be tall enough for me.

At 61, 6'3" and 280lb, I'm finding that his racing gears don't work so well for me. I ride in the SE where there are no giant hills, but I would like to find some lower gears. I have started riding on rail trails, round town, and with some organized groups. A goal would be to ride in the BRAG Atlanta to Savannah ride.

Presently it has a 170 mm crank with 52t and 42t chainrings. The crank says Bianchi, but the other parts are all Campy so I'm guessing that it must be too?

The rear freewheel? most likely, is a 11t-23t 7 gear set. As you can see in the sideways photo, it has a Campy Novito Record RD, and from what I'm learning, I'd say that's a short cage?

So from my studying, I can either try to find smaller chainrings, maybe a 48-34t. try to install a tripleizer with the present 52,42,30 maybe?
Or go to the other end and try a 12-32 freewheel, with a different RD?

I'm just throwing these gear numbers out as I haven't advanced to the point of understanding the whole gear ratio thing yet. I would appreciate any advice or input from those of you who know.

I have started on the other end by getting a Rivendell, Nitto albastache bar and stem to try to make it easier on my old back.

^ most likely, a new freewheel to replace your corncob is all you need.

look for a sunrace or ird freewheel in 14-28t. you may need to lengthen your chain as well. i like sram pc-850 chains. you can get this stuff new on ebay. an ird freewheel may be more difficult to find.

I believe that your crankset is actually made by Ofmega. In any case, since you are not living in truly hilly country I'd suggest getting a 13-28 freewheel. That'll take you from a 49" low gear down to a 40" (a 22% lower gear!) and will not cost you much, just a new freewheel and chain. The Nuovo Record derailleur although rated for a 26T maximum rear cog size can almost always be made to work with a 28T as long as you fine tune the chain length and rear wheel position so that the jockey wheel is rotated far enough forward of the cog.

If that isn't low enough for you then you have several choices:

1. Change the rear derailleur and buy something like a Suntour Cyclone or Shimano Deore to go with a larger freewheel. You might also be able to keep the derailleur and buy a Soma long cage as discussed above. This will get you up to perhaps 32 teeth max, though don't quote me on that.

2. Keep the Nuovo Record derailleur as is and change your crankset to something with a 110 mm bolt circle and a compact crank setup (e.g. 50-34T). There are several of these from Holdsworth, Velo Orange, IRD, etc. You can't just by new chainwheels because your 42T chainwheel is already the smallest size possible for your current crankset.

3. Do what I did and several others above did and go whole hog with a triplizer (available from redclover), new bottom bracket, and Soma long cage for your Nuovo Record derailleur. I did this because I routinely ride 15% grades, which probably don't exist in your neck of the woods, so you may not find this route necessary.

Whatever you do, check out the gearing on a gear calculator such as this one (which allows you to compare two different setups): HTML5 Gear Calculator . You should be looking for fairly even gaps with few greater than 10% except perhaps the last step down to your granny gear. It's helpful to click the button that says "teeth" and change it to "gear inches).

BF members have responded in typical zebra hunting fashion. "When you hear hoof beats, think horses not zebras!" In other words, explore the simplest, most elegant (in scientific terminology) solution to a problem before reinventing the wheel! Read my sig below...

Now that I've offended some.... A few years back there were no less than 4 bikes on a Guy Fawkes Day, British bike only ride that were running Campy NR derailleurs with 28T or larger FWs, including 2 bikes with 34T FWs!!!

14-34T x 2 Bikes



Raleigh International running a 26T or 28T FW with a Campy NR triple.



My Holdsworth with a 13-28T FW and 52-42 CRs




I'm running at least a 28T FW on all of my NR rear derailleur bikes. Here's a few of them. they all shift fine:



13-31 Regina Oro on my 1970 Gitane Super Corsa as purchased.



Pictures above are proof that running a freewheel with more than 28T can be done on most bikes! You will probably have to play around with chain length and wheel position in the dropouts plus you may not be able to hit all 10 gears depending on the chain stay lengths. Your International has long chain stays so you may be able to even get a 30T FW to work.

Try those minor changes first before spending a fortune on new components. If that doesn't get you low enough gearing then you can try other options but at most you are only going to be out the price of a freewheel and chain!

I've never used one (yet), but I think I would try Jon's Red Clover tripllizer before I drilled the crankset. These use a special inner 144bcd chainring with drilling for a 74bcd inner ring.

So as a first step, I can try one of these.

Shimano TZ21 7 Speed 14 28T Freewheel | eBay

And then do more if needed

Just installed SOMA long cage, beautiful!

Like many others posting here, I highly recommend the Soma long cage for use with old Nuovo Record derailleurs. I have a 14-28 freewheel on an old Dawes Galaxy. Before I went long cage, I bought the IRD 46-30 crankset to see if that would give me low enough gears. It did, but the Campy record derailleur was so unhappy in the 28, and it was miserable in any combination using the big ring in front. I wanted a 10-speed that had more than 6 operational gears, so I got the SOMA cage and it works perfectly. The part is reasonably priced and installation is easy, as well. It looks a little funky, but if you absolutely must have that classic Campy look in the rear, go with a 12-25 freewheel and a triple crank with an inner ring of 24-26.

Be sure to get a new chain also. Badly worn chains destroy freewheels and are cheap to buy. A SRAM PC850 or 870 8-speed chain is good, as are the KMC 8-speed chains.

I've just finished setting something very similar: 48-30 up front, 14-28 in the back, with the long cages on a NR rear derailleur. Zero problems in the back, but that extra two-tooth gap up front has caused the NR front derailleur to be, shall we say, finicky. If it is too low on the seat tube, the chain won't shift from the mall chainwheel to the large one, instead jamming between the chainwheels and the FD cage. (If it's really too low, you get the obvious problem of not clearing the large chainwheel.) If it's too high, the chain rubs on the spacer bolt assembly at the rear end of the cage when in the 30x17 gear. (Cros-chaining to 30x14 is not an option, and I'm okay with that.) I haven't yet found the "just right" spot, but it is clear that that spot is veeeery small, if it exists at all. If I had not gotten greedy by going for the 48-30 combo instead of staying with the 46-30, there would be no problem. But since the bike will be taken on hilly terrain, I wanted that 93 inch high gear.
