There is always the bike workshop.
Adelaide Community Bicycle Workshop, Saturday mornings 9 am to 12 noon - should have tools you need plus manual, and volunteers to help. No fixed charge, donate what you think is fair, to help keep the workshop running.
Chain jammed between frame and crank - you might need to get the crank off - the workshop has crank extractor tools, and stands. Then, when chain is back on, you might need to check why the chain came off e.g check your gear adjustment and derallieur - the workshop has tools for that.
& if you need parts, Plympton Cycles is <1 km away. Mike.
It prob needs a qualified mechanic to look at it.I have no knowledge about pulling off cranks etc
where is the bike, and how far can you transport it, and when? I am a mechanical engineer, have built several bikes and do all of my own bike maintenance, and as I have returned to study can always do with a little extra change...
Put on a glove or get an old rag and just worm it out. Don't yank it, just wiggle it around with a bit of 'tender force'. Ive had this happen in a 24hr solo race a few times. No biggy. Ive never had to remove the cranks either.
Post some photo's here Troy, chain breaker tool is all you need
heres the best pic I could get
This is pretty straightforward:
Use 8mm hex key to remove crank bolt, and crank removal tool to remove crank and chain rings in one piece, this will take about 3 minutes to resolve - including re-assembly.
After that, just setting up the rear wheel on the trainer again and adjusting front derailer cable to ensure no repetition.
to be honest, i'd feel like a theif if i asked for money to do this ;)
If the chain is worn (easy to measure) you might consider replacing it, along with rear cluster. teeth on rings in photo look ok though; they typically outlast the cluster and chain considerably.
if you'd like help with any of it, or just to see how to do it without damaging anything in the process, friend me and we'll set something up.
dunno what happened but all of a sudden I had to really yank on the lever to get it to go to the big ring then when I threw it back to the small ring thats the result
Sometimes a trusty screw driver can be used to lever the chain ring away from the frame so the chain can be pulled out...
