Hi, I'm building an oddball bike with t140 hubs laced to Borrani flanged rims. I need to put drums on. I have been told that early TR65 Tiger Trail drums fit. The part number is 37-7138. The hubs are 4 bolt for the discs. Any help would be appreciated. Not to keen on buying a drum and it doesn't fit. I don't want to modify things too much, so a straight bolt up deal would be good. Thanks Neil

you mean drum brakes~?

they are a different part completely from standard T140 disc "bobbins"

you can stick pretty much any brake hub on a bike with the correct spindle and bearings, dependant on wheel size.

I'd guess that early T120 OIF brakes would fit pretty closely, but you might have issues with RH/LH gear changes.

The later Thunderbirds had a rear drum I think?

Maybe ring Reg Allen as they probably know what will fit with minimum effort
