the stronglight one is a good bet. i'd change the BB at the same time as well, which you can get from PX. if you want to do the job yourself, you'll need to buy or borrow a crank puller and the relevant bottom bracket removal tool.
Thank you for that. Am I ok to go with 48t (I am currently running 46t) for better gearing ratio for me? I will get new BB too. I'm going to get the local bike store to change it all out and new chain too.
