Struggling to find a single speed chain ring.

I'd like a dedicated single speed chain ring 50t - needs to be 130bcd.

I've looked at parker, merlin, wiggle, CRC, charlie's (who perhaps would have one but is out of stock of pretty much everything) but all I can't find anything 50t, just much smaller.

Are there any other good stockists to check - maybe some that are more single speed focused?

    Yep - search for Gebhardt, or possibly Stronglight? Look for velodrom shop - tis a pretty trackie type of item!

    Thank you, that looks just the ticket.

    If you go here quickly they have one for a tenner - make sure you get the right chain:

    Thanks - I've emailed them about it.

    Assuming the right chain is used with the chainring is the rear cog irrelevant (it's a 3/32) - I read somewhere that this would be fine?

    You want to try and match chainring and sprocket size if you can - though a 3/32 sprocket and indeed chainring will both run with a 1/8th chain - be a bit noisy though!

    (Obviously you can't run a 3/32 chain with any 1/8th sprockets or rings!!)

    SJS are expensive... but if you can't find it elsewhere they often have it

    apologies for the hijack...

    i am running a FG and keep having to move rear wheel backwards, have had to do so about 3/4 times now. This might be due to wheel creeping forward, or chain lengthening... thinking about getting those little stoppers to stop sheel slippage, anyone use them?

    it does about 100 miles a week and has done since sept last year, time to get a new chain?? or just run this one into the ground??

    Combination of all of those factors will lead to your rear wheel needing to move back in the track end (presumably you have a track end or horizontal dropout?)

    Chain stretch shouldn't really happen to a noticeable degree over just one week - but over the period you've described, that amount of adjustment is about right, tbh.

    I use a chain tug on the drive side of my Pompino - just got the cheap On-One one... You can add one on the non-drive side if you have OCD, but it's not necessary.

    Your chain will still stretch over time even if you use a tug, however!

    I have chain tugs on both sides - they came with the bike.

    The non-drive-side one is very handy (in allegiance with the drive-side one) for centre-ing the rear wheel.

    ... for centre-ing the rear wheel.

    How long did you spend wondering how to type "centre-ing"...? Go on, own up!!

    :-)

    I have to adjust the chain tension on my FG weekly (100 Miles). Must be the huge torque I'm pushing out.

    Or the lack of torque you apply to the nuts... :P

    Yes - they can be handy for that - a lot of the guys at my track league have them on both sides - but the wise-old dogs swear by doing both nuts at the same time, by hand, until the chain's in tight, then tightening the nuts with the spanner, and finally snugging up the tensioners - they don't use the tensioners alone to pull the wheel back - this kind of makes sense, as the tensioners often have pretty small threads, and I guess you could strip them?

    They're obviously fiddling with gearing a lot more at the velodrome than on a typical commute mind...!
