  • Asked by Campbell Ritchie
    on 17/07/2022     I have the older style chainring fixed to the crank and the two are attempting a bid for freedom. I presume I can use the new crank and separate ring. Do I need sleeves, or do they come with the crank? Do I need to change the bottom bracket? Answer:
    You will need to order the new crankset and a bottom bracket, links as follows:https://brilliantbikes.co.uk/brompton-chainsets/1940-brompton-crankset-with-50t-spider-chainwheel.htmlAlso available as 44 and 54 tooth chain ring.https://brilliantbikes.co.uk/brompton-bottom-bracket-cartridges/849-brompton-bottom-bracket-jis.htmlPlease note the tools required as stated on the bottom bracket page.Hope this helps and please let us now if you have any further questions.
