Anyone retained the 27x11/4 wheels on their builds

If so I'd love to have a look.
I've got a broken down old Peugeot cheapy and it still has the 27" wheels with L/F hubs, the rear one being a nutted job. If a BMX freewheel fits directly on it I might bother grinding all the brazings off and going for it.
Still sitting in my box is an unused On-One s/s chainset, some Mafac Racers and various bars and stems.
I fancy an 'clubman' style build

Just finished restoring a Raleigh Richmond mixte and I stuck with the 27 x 1 1/4 wheels, but that was mostly because they were in good nick and it didn't seem necessary to replace them. Haven't got round to putting this in projects yet, hence the relatively crappy photo.

If the wheels are in good nick best to keep them on as that is what the bike was designed for. If you fit 700c you will find the rim is 4mm below where it was with the 27's and you will have to make sure your brakes can cope with the extra drop. 4mm may not sound much but you will be surprised how often the brakes are already on their limit with the 27's plus it can make the frame look gappy.
L/F hubs look so right and track nuts help prevent your wheels being stolen. The thief has to come with the right size spanner.
As to tyres, Continental Gatorskins are available in 27 x 1 1/4 size. Found some at a bargain price on the net today.
I guess you can sayI am recommending you keep them !
Best of luck with the build; let us know how you get on.

I don't know if this refers to me, but I can tell you that although some refer to me as 'retro man' I have thrown away all my 27" wheels and so far I haven't regretted it for a moment.

Chris, you actually binned some old equipment?

I do hope to get out on some rides with you soon, how are the Hard Day plans progressing?
