Just started building my motolite up and noticed that if i run the chain on big ring at front and smallest cog at rear , the chain rubs the seatstay !!
any ideas ??
pics below to show how close it is

Cheers Tony

It's not a gear you'll use often, but it shouldn't be like that. I'm in the middle of cleaning mine just now so I'll have a look once it's all reassembled.

Initial thought is perhaps too many BB spacers? There should only be one on the drive-side cup and none on NDS. Assuming its an external hollowtech style BB.

look at your chainline – theres nowt else to tweak to sort it – as long as frame is straight

Thought it may have been that myself but its the same whether there is 1 spacer in there or no spacers drive side ??

Just looked at mine and it is fine.

Check you bottom bracket spacers, your cassette is all the way home and the hub (if hope) has not dropped the insert out, as they sometimes do.

Checked cassette is all the way on
Tried xt wheels and a set of mavic crossride , both the same??
and NO BB spacers !! .. still rubs with no spacers or 1 spacer ?

check pivots & check rear end alignment, is it new or secondhand?

take measurements from both sides of frame (if symetrical) and see if they tally, could run a string from L rear dropout / round seat tube / R rear dropout and measure frame centre (again if rear end is symetrical)

Starting to think it may be an alignment problem 😥
Frames new , just had it imported from the states !
also tried a older chainset , with splined BB and still no better

Here's the clearance on mine in that biggest gear:

It's only about 1mm but it's enough.

Is your frame second-hand? Possible misalignment?

what **** designed that?

get a refund and buy a specialized

Must be alignment then.

Thanks for your input.

Indeed. What a ****

Have just spoke to jensons and am awaiting there views ?

buy a specialized

At least buying a Spesh you know for sure that your alignment will be out 😉

Also worth noting that (on mine anyway) that the only way I could get the chain to stop rubbing in certain gears was to run two spacers on the non-drive side of the BB. Odd but worked. Oh and watch out for cable rub on the rocker/ brace and frame around it if clearance for cables is tight.
