Retro Newbie
Hello,
I am new to the Forums here but am hoping this is the right place to post as I am going over to Ireland in September and hoping to do some renovation/modification work on my Dad's old early 1980s Raleigh tourer to make it more rideable on the beautiful but very undulating and often punishingly steep roads of Co. Donegal!
My first query is to try to establish what the original model was so that I can establish what the original spec would have been and hopefully then modify the gearing to make it a little less leg-busting to ride over the local terrain (it currently has what by my count is a44 46 single chainring at the front and 6-speed 14-23 cogs at the rear ).
The Frame number (on the rear of the seat tube) is NA2016824.
Which according to the info I could find online (e.g. here and on Sheldon Brown) means it was manufactured in the Nottingham in January 1982 (I think but TBC....)
N=Nottingham
A=January
2=1982
016824=Production Unit No.
But this still leaves me unsure as to what the exact model was. I'm pretty sure it was some variant of the Record, but the Record Sprint would have had a double-chainset and drop handlebars so this is either some kind of more humble variant or there was some after-market modification as it has the single chainring and flat alu bars. It also doesn't help that any model decals there may have been seem to either have been removed or painted over (unless there never were any as it has only the Raleigh branding and some decorative decals).
The existing front chainset appears to be a 46-tooth chainring. Not sure about the BCD (though the measurement between two the outer edge of two adjacent boltholes is ca. 65mm - see image attached). The cranks are marked Thun-geschmiedet 170mm.
The rear derailleur is a Suntour VX which according to info here can take a max of 28 teeth at the back (presumably subject to making the correct adjustments to chain length).
The bike is currently equipped with one Suntour Power shifter lever which is mounted on the stem and the rear derailleur runs above (not below) the BB and a little braze-on cable hanger / runner above the BB.
Once I've established what the original model was, my idea is to try and change the front chainring or entire chainset to something a little easier-geared but period-/model-correct (perhaps a 52/42 170mm Thun-geschmiedet if I can find one though that's not going to make a massive difference relative to the 46). And/or to try and add a lower (28?) cog to the rear (though no idea what kind of rear hub it'd be running and I don't have access to the bike from where I am now...)
Basically I'm looking for whatever would be the simplest option to modify the gearing for hillier riding. If I go to a dual chainring at the front I will also have to purchase a compatible/period front derailleur (Sachs Huret Club II was original spec on Raleigh Record Sprint) and presumably some Suntour Power levers for the downtube, cables and then figure some way of running the front derailleur cable round the BB...
Otherwise, a simpler alternative (but one which might not be so true to the original spec/spirit of the bike) would be to source a smaller front chainring (perhaps even a newly produced compatible single chainring crankset) that could be fitted to the existing crankset and would be compatible with the rest of the drivetrain. Again presumably it'd need to be a cottered crankset (square tapered??) and I need to establish the BCD of the existing crankset to find something compatible.
I realise it might be leaving things a bit late to source parts in time for Sept now but any tips on what might be the best way to proceed and what parts, tools, etc. might be necessary would be very much appreciated (15mm socket wrench for removing the crank?). It's pretty difficult to source parts locally and there are limited tools available where I'll be so I'm trying to plan ahead this time so I can get the work done while I'll be there....
Also sorry for the dirty cassette, derailleur and rims on the photos and the non-original spec tyres (and seats and mudguards...) but the bike is what it is at the moment and some more rough-shod tyres were necessary given the somewhat rough nature of the roads and tracks where the bike now gets whatever rare use it gets these days - usually just once a year when I'm over on holiday to see the family!
Sorry if that's a lot of questions and info to process.... but I haven't done any posts like this before so am kind of thinking out loud...
Thanks in advance for any ID, other info, tips or guidance you can give me!
P.S. Am including a pic of this "Ride the All Steel Raleigh" letter-opener (that's what I'm sure it must be unless anyone else has any better ideas...) which I found in the shed as a bonus/curiosity. Pretty sure it doesn't have anything to do with the bike directly and possibly predates it considerably but thought it was nice anyway ;-)
