UK_SPAWN Posted June 22, 2013 Report Share Posted June 22, 2013 Hi all, yes its me again I'm going to upgrade the front rotor to 180mm hope saw on my Trial Zone (currently 160mm). Put all the bits together in tarty basket and then went to check the bike and just make sure I'm ordering the correct adapter (adapter F) (on tartybikes it says adapter F is for 180mm front 160 rear) So I look on my bike and see this... "F" How come im running a 160 on an adapter thats application is for 180?? Has it been installed upside down maybe? Here is a picture...

Kevinfor Posted June 22, 2013 Report Share Posted June 22, 2013 As far as I know some brakes come with just pure adapters from IS to post or vice versa, so no +10 or what ever you call it. Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 22, 2013 Author Report Share Posted June 22, 2013 I see, it was just confusing seeing F and that was the adapter im ordering lol Anyone else think its just a "+0" adapter? Cheers Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 22, 2013 Author Report Share Posted June 22, 2013 This is what I have. And it states 160mm on the internet and marked F. I think I have figured out what the problem is. Different manufacturers do not standardise adapter markings, so F from brand X is different to adapter F from hope.. How confusing! Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 Can anyone who is running a front 180mm disk with a post mount calliper and IS forks tell me what adapter to use. Still a bit confused about this. Cheers Quote Link to comment Share on other sites More sharing options...
krazykid009 Posted June 23, 2013 Report Share Posted June 23, 2013 The adaptor is on the wrong way round... Flip it around, install a 180 and bobs yer uncle! Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 The bit with F on should be at the top then? I tried to do this last night and although I didnt bolt it together it didnt seem to change the size when I fliped it over and lined it all up... I thought it was that but now im pretty sure its not that. Its either I havr an adapter maked F, that is different to the adapter marked F from tarty bikes. Unfortunately the pictures on tarty dont show adapter F I dont think. If that is a picture of F on the last image, then that is the adapter I already have, but its not 180 my disk is 160.... Can Adam@tartybikes or anyone there confirm. I have echo (sl?) Curved forks with IS monts. And a hope trial zone post mount calliper. I need a definite 100% answer ready for ordering new disk. I cant work it out... Quote Link to comment Share on other sites More sharing options...
krazykid009 Posted June 23, 2013 Report Share Posted June 23, 2013 Trust me, it is on upside down. Just flip it over and get a new disc. Quote Link to comment Share on other sites More sharing options...

UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 Normal (160mm) how it came: Reversing the adapter provides more space. You may be correct krazykid. Does this look like enough room for 180? Im looking at my rear 180 and it looks like it may just fit... Cheers for the help. Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 So upside down adapters cancel out the increase in size? So a 200mm adapter used upside down would yield 180mm? I found this chart... I definitly have adapter F, and there it says rear 160? It dosent state any for front 180mm? Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 (edited) http://item.mobileweb.ebay.co.uk/viewitem?itemId=170412350924&cmd=VIDESC This item states now that adapter f used in a front yields 183mm...

UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 Im going to order the disk (180) Ill let you know how it goes.. Cheers Quote Link to comment Share on other sites More sharing options...
dezmtber Posted June 23, 2013 Report Share Posted June 23, 2013 If you use the hope 180 trial or trial zone rotor You need the j adaptor for 183mm Quote Link to comment Share on other sites More sharing options...
UK_SPAWN Posted June 23, 2013 Author Report Share Posted June 23, 2013 Yeah I wanted a hope saw but I may just get a 180 trial zone as its designed for trials. Cheers I was just baffled that up side down works because its the first thing I thought but instantly dismissed it as "a silly idea and it would be same other way" I even took it off and quickly lined it up... wasnt untill I bolted it in with the F mark at the top and guesstimated based on my rear rotor that I saw that maybe I DO have the correct adapter, and just by fluke it happens to work on a 160 if used upside down... Seems to be the case. Quote Link to comment Share on other sites More sharing options...
