Hi, sorry if this might be an obvious question but is this crank going to fit my bike ?

My bike is BB386 which the new crank says it is but in the description it says it's got a " Lightweight BB30 bottom bracket spindle gives additional stiffness " which has got me confused due to my ignorance of cranks/BBs/spindles/etc.

My bike is the following...

The crank I'm looking at is this one...

Thanks

    No. Your bike is BSA so a standard 24mm axle. There's probably an adapter on the market but tbh you're better off buying a 6800 chainset.

    how is the rt58 aluminium frameset?
    Regarding the crankset, just buy the 6800 or 5800 from shimano, much less aggravation with the bearings. Even an R565 for £49 would be good and certainly prettier than the tiagra crankset which must be ugliest bike component ever made...

    It's my first racer so I don't have any thing to compare it to but apart from the saddle not being the most comfortable and a slight tweak to the gears it's been great.

    For the price V's spec'/weight I thought it was a good buy for my fist decent racer.

    Even better value as I got it when it was £600 rather than the new £700 price ! :)

    It comes with a FSA Gossamer Compact BB386 EVO Chainset rather than a tiagra. I was looking at the other FSA chainset as it was on offer for a good price and was iirc 250-300g lighter than mine.

    If your bike came with a BB386 chainset then it would have the appropriate BB installed to allow you to make the upgrade. The specs list the BB as BSA which doesn't really make a lot of sense. Might be worth sending them an email.

    You can get a bottom bracket that fits a BB386EVO crank to a BSA threaded frame, so it's entirely possible that's what you have.

    Having said that, there are more worthwhile upgrades yo could make, like wheels.

    In that case yes, it will fit.
