mtbsteveo Posted March 6, 2014 Report Share Posted March 6, 2014 Does such a thing exist to allow you to put 4 arm chain rings onto a spider which in turn would screw onto a set of freehweel cranks? Cheers for any help. Quote Link to comment Share on other sites More sharing options...

AdamR28 Posted March 6, 2014 Report Share Posted March 6, 2014 Close - but 5-arm: http://www.k-124.co.uk/product.php?product_id=123(If you wanted one could do one about £25) Quote Link to comment Share on other sites More sharing options...
J.KYDD Posted March 6, 2014 Report Share Posted March 6, 2014 We stock these Shun freewheel cranks: http://www.sjscycles.co.uk/shun-alloy-104-pcd-4-arm-freewheeling-cranks-170-mm-silver-prod23859/ Wouldn't ever recommend them for trials use though, pretty sure the base freewheel is a really basic Dicta unit. Thorn cycles only use them occasionally for lazy tandem stokers! Quote Link to comment Share on other sites More sharing options...

MacYoda Posted October 8, 2014 Report Share Posted October 8, 2014 Here is the definitive freewheel spider company, 4 arm, 5 arm, and you can mix and match them ... http://bikemotive.myshopify.com/products/freewheeling-crankset-for-ebike-bikemotive I went cruising the web for spiders the other day and discovered that trials bikers use freewheel cranks previously I only knew about them because it came in my electric bike kit. And here is the definitive high quality bolt to freewheel for cranks made by White Industries which also makes your single speed chain ring freewheels that are used heavily by trials bikers ... http://www.sickbikeparts.com/catalog/product_info.php?products_id=62 White Industries freewheel chain rings, notice scroll down the page "Trials freewheel" 72 points of Engagement ... http://www.whiteind.com/free-wheels.html I notice there are quite a few freewheel cranks available in the UK but only a handful of North American companies carry them, because trials is popular in the UK but not the USA. I built a very powerful electric mountain bike, 85 lb, I weigh 200 lb, up to 33 mph and climbs like a billy goat. I have ridden it frequently for the past 2.5 years where I used the cheaper version of the freewheel and it worked great, I never did ANYTHING to it, never oiled it, it just worked! BUT there was a LOT of lag in the freewheel! These are available all over the web, I think Amazon has them a couple bucks cheaper ... http://www.sickbikeparts.com/catalog/product_info.php?products_id=178 So now I am building a second eBike with higher quality parts to see what its like and you benefit from my research.

MacYoda Posted October 9, 2014 Report Share Posted October 9, 2014 (edited) Sickbikeparts has their spiders back in stock now. These prices are probably the best you will find for spiders, $22 to $24 ... http://www.sickbikeparts.com/catalog/advanced_search_result.php?keywords=Freewheel+Spider&search_in_description=1&x=0&y=0 Edited October 9, 2014 by MacYoda Quote Link to comment Share on other sites More sharing options...

Thorn cycles only use them occasionally for lazy tandem stokers! Think you misread what he was after Josh... I read that he was after a 4 bolt spider that screws on to a 1.37" x 24 tpi thread found on most trials cranks designed for a FFW. I.E. A 4 bolt version of what Adam linked to.

BTW, all of the freewheels I link to above have 1.37" x 24 tpi threads. If he wants it without the freewheel, he did say freewheel crank, then there are these threaded cog chain rings, and somewhere I think I also saw an adapter that would bolt onto the spiders I link to above ... http://www.modernbike.com/product-2126188314?gclid=CjwKEAjw5NihBRCZmdLkuuTHyWYSJACtCY0JL_qCk5YOjYEmuCIomol4jPljqHG5DFQJ5Qxn0haTjxoCzzbw_wcB Origin8 seems to have a lot of these, 1.37" x 24 tpi thread ... http://www.bikesonline.com/origin8-torq-lite-track-cog-silver-1-2-x-3-32-14t.htm?gclid=CjwKEAjw5NihBRCZmdLkuuTHyWYSJACtCY0JRVeVifCzSGkjdVbsQWXunfPQhUYDqitkr6HCFMrwvxoCbEDw_wcB Wow, Surly even has a dual threaded cog ... http://surlybikes.com/parts/drivetrain/dingle_cog Quote Link to comment Share on other sites More sharing options...
