zoster Posted October 21, 2009 Report Share Posted October 21, 2009 (edited) Houdy!i have a 24". going around town sucks with the trials ratio, but having a dérailleur also sucks. i am still waiting for some company to make a 2-geard hub / freewheel made for abuse! i know about the Hammerschmidt, but the price tag is ludicrous. you could also use a tensioner that can be (sort of) easily moved from one cog to another, but this brutally separates the trials part of the ride from the commuting part, which takes away from the whole idea of a street-trials bike.anyway, i think you all know what i am talking about, i was just wondering if some new product came along or anybody came up with a brilliant idea for this purpose, that we all missed.

Dan Clark Posted October 21, 2009 Report Share Posted October 21, 2009 It's hard enough to make a freehub which doesn't blow up when people use it for trials already, trying to do this with a multiple gear system inside would be asking for the world.Not to mention it would weigh a ton in a sport where people are drilling holes out of their brake levers and cutting off tyre knobbles to save a couple of grams.Just get a derailleur, they aren't as bad as your making out, if you're only using two gears you don't need a shifter either.

Luke Rainbird Posted October 21, 2009 Report Share Posted October 21, 2009 Rohloff + lots of spacers? Not particularly quick but would be shiftable in a shortish time to roll into/out of town Quote Link to comment Share on other sites More sharing options...

cam217 Posted October 21, 2009 Report Share Posted October 21, 2009 (edited) i was wondering this as im going to buy a street bike, i was just going to go with the tensioner off and chain onto a different cog then flick the tensioner back on method.but i'd like to find out some other ways too, if anyone knows anyother ways.

King C Posted October 21, 2009 Report Share Posted October 21, 2009 I recently wanted to do this but got a rohloff instead. Look into the tensile, tryall or atoms tensioners. They look like they might have enough lateral movement to be able to quickly swap between cogs. I havent tried it so I dont know if it will work or not.

durkie Posted October 22, 2009 Report Share Posted October 22, 2009 white industries makes a freewheel with two gears on it: 16/18 or 17/19 tooth. you have to move the chain by hand. Quote Link to comment Share on other sites More sharing options...
J Trials 31 Posted October 22, 2009 Report Share Posted October 22, 2009 white industries makes a freewheel with two gears on it: 16/18 or 17/19 tooth. you have to move the chain by hand.I think that they suggest you don't use that for trials though. Yeah, like a 3 speed internal trials hub would be awesome. I wouldn't care about weight so much as it's on a street bike. I'm sure with the technology now days it's possible to make it reasonable in weight anyway. Quote Link to comment Share on other sites More sharing options...
J.KYDD Posted October 22, 2009 Report Share Posted October 22, 2009 Im not sure on the price, but there is an alternative to the new Hammerschmidt crankset.Im pretty sure NC17 and someone else have done them too, think the gear change is somehow operated by a button at the centre of the drive side.Think you change by pressing it with your ankle, which may be an issue, especialy with all the new fasionably spinny moves of street trialsJust a thought.....

Dan Clark Posted October 22, 2009 Report Share Posted October 22, 2009 Just get a mech, run a tiny bit of cable from the cable adjuster and use the adjuster, it should have enough adjust to switch one gear.Or use a screwdriver and do up the stop screws to change gear.Far more sensible than trying to use a tensioner to change gears anyway.

jambo Posted October 22, 2009 Report Share Posted October 22, 2009 I found something that works perfect its called man the f**k up! or get a short road mech with an old school thumb shifter under the saddle like back in the day. I prefer the first method. Quote Link to comment Share on other sites More sharing options...

cai Posted October 22, 2009 Report Share Posted October 22, 2009 (edited) I recently wanted to do this but got a rohloff instead. Look into the tensile, tryall or atoms tensioners. They look like they might have enough lateral movement to be able to quickly swap between cogs. I havent tried it so I dont know if it will work or not.It would work with the Tensile tensioner, would take about a minute to re adjust it properly to the secondary gear, wouldn't be too bad atall..

ogre Posted October 22, 2009 Report Share Posted October 22, 2009 if you ran a smaller sprocket next to your current sprocket and used a tryall/atomz/tensile tentionor, you could change the gears with minimal faffing, i've toyed with the idea a few times (biking 7 miles home on a trial bike ftl) but it'd be no good for your chainline and putting alot of hammer through the bent chain is probably bad, or if your lucky you can misalign the tentioner to sit the chain between the sprockets and you can free-coast, stamping on your pedals usually pulls the chain back onto the sprocket (my f**ked up old rohloff could do this, and 6 times out of 10, work every time...)

TROYston Posted October 24, 2009 Report Share Posted October 24, 2009 Well you could just de-lace the wheel off a Rayleigh chopper, internal gears fixed to a cassette?Or how about a separate crank arm + bigger sprocket and then just Jimmy it on when you want to go riding?
