mossy7 Posted April 15, 2019 Share Posted April 15, 2019 Does anyone know the weights of the 6x13 and 8x13 8 spoke wheels that Caterham supplied as a fore runner to the Apollo wheel? ThanksAndy Link to comment Share on other sites More sharing options...
SM25T Posted April 15, 2019 Share Posted April 15, 2019 Considerably lighter than the 17" and 19" wheels and tyres I have been swapping over on the Mazda today, that's for sure !!! Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 15, 2019 Member Share Posted April 15, 2019 There's lots of data in the archives, but unfortunately scattered across lots of threads. If you can face looking through it how about tabulating the values as you go?Jonathan Link to comment Share on other sites More sharing options...
mossy7 Posted April 16, 2019 Author Share Posted April 16, 2019 Ok. With the help of the following great blog courtesy of Daniel, I have a bit of an answer-( apologies for the copyright theft!)http://www.caterhamr500.co.uk/2016/07/new-cr500s-with-weights.htmlCaterham 6x13 eight spoke weighs 4.4kgCaterham 8x13 eight spoke weighs 4.7kgFrom CC website:-6x13 Apollo weighs 4.16kg8x13 Apollo weighs 4.76kg6.5 x15 Orcus weighs 5.8kg6x 14 Classic weights 4.88kgSo, I'm looking at a 5kg weight reduction going from 15s to 13 inch eight spokes without considering tyres.

SM25T Posted April 18, 2019 Share Posted April 18, 2019 So you dont need to go on that diet after all ! Link to comment Share on other sites More sharing options...
Tony P Posted April 18, 2019 Share Posted April 18, 2019 I weighed a lot of different wheels and tyres some time back; I’ll see if I can still find my notes.(From memory an ACB10 was at least as good a weight saving as a mag wheel; but I can’t recall the detail.)

mossy7 Posted April 18, 2019 Author Share Posted April 18, 2019 No diet indeed and an increase in power to weight ratio! Win win in my book. Now..pass the whisky and chocolate. Link to comment Share on other sites More sharing options...
rj Posted April 18, 2019 Share Posted April 18, 2019 I've just weighed ordinary cap head bolts and titanium bolts to compare the weight. It looks like some 200 gramms can be saved for a MB wheel simply changing to titanium bolts. That would leave the lightest fronts at 2.9kgs (!) Unfortunately the CR500s are no longer available (at least not from CC and not in the old compound) and the ZZS' are a lot heavier. Link to comment Share on other sites More sharing options...
