    Yeah, they are bearings. Hope do some replacements with nice bearings that I've stuck on some worn out 105 derailleurs in the past. I'd imagine they are comparable to ultegra, though.

    Isn't there then a risk that the chain is too short for the large/large combination?

    Consequences if a chain that is too short seem much worse than one that is too long, based purely on internet horror stories.

    The way I've always calculated chain length for Shimano 2x systems is either:

    1. Use an online calculator like http://www.machinehead-software.co.uk/bi­ke/chain_length/chainlengthcalc.html

    2. Wrap a chain around the biggest chainring and biggest sprocket to see where they meet. Add 2 pins, and cut the chain there.

    I recently bought a bike that uses SRAM Rival 1x gears, and would like to know how to calculate the right chain length for it, primarily so that I can make sure I avoid buying a replacement chain that is too short out of the packet.

    The SRAM manual (page 14 of https://www.sram.com/globalassets/docume­nt-hierarchy/user-manuals/sram-road/driv­etrain/95-7518-007-100-1x-rev-a-road-sys­tem-user-manual-eeu.pdf) suggests wrapping the chain around the biggest sprocket and the chainring, and then adding 4 pins. So that's similar to what I've done in the past for Shimano.

    Using that method, it looks like I should have use a 55 inch chain. The online chain length calculator also agrees with 55 inch.

    However, the current chain on there (came like that from the factory) has an extra 6 pins of length on top of what either of my normal methods think it should be. It is 58 inches.

    The bike has ridden fine over the past year, with no noticeable issues. When I come to replace the chain should I replace like for like and go with 58 inches? Or should I trust the SRAM manual and online calculator and go with 55 inches? I'm loathe to "just try 55 inches", as once I've cut the chain it'll be a bit of a pain if I decide it's actually too short and I should go back up to 58.

    Ah I'm sorry, total fake news! I must have been remembering it is not vegan, but not the right reason.

    It isn't I'm afraid. Contains whey protein. I'm also on the hunt for good vegan protein powder, not found any yet but will post if I do

    All my American colleagues love me for introducing them to fortnightly. No more spending days fretting over whether that bi-weekly report needs to be done twice a week, or every other week.

    And when they say "every other week" my mind boggles at why they knew this phrase but have not been saying that for the avoidance of doubt this whole time.

    The specialised insoles were not great in my experience. Go see someone who can do you a custom footbed. Simon at Cadence in Crystal Palace will do you a pair for 90 quid. Best 90 quid i ever spent on cycling

    Chapeau! That used to be on my commute, but I never got close, even stupidly early in the morning you're held up by traffic.
