Miles Mallinson Posted February 24, 2011 Report Share Posted February 24, 2011 Just watching some of the newer Danny Mac videos, as he runs a 4 bolt crank there should defiantly be more 22-24t bashrings, there are a few like MRP and truvativ but there should be more of them, someone like trialtech should make one or a inspired version of their screw on one for 23t also different sized 4 bolt granny rings would be good.

bikeperson45 Posted February 24, 2011 Report Share Posted February 24, 2011 Does anyone else still run 22-18? Just out of curiosity... Quote Link to comment Share on other sites More sharing options...
Miles Mallinson Posted February 24, 2011 Report Share Posted February 24, 2011 I used to, it was good for natural but for me it was way to easy for pedal ups and gaps, then i rode 24-18 that was slightly better Quote Link to comment Share on other sites More sharing options...
bikeperson45 Posted February 24, 2011 Report Share Posted February 24, 2011 Everyone else seems to be running all these tiny little cogs now, one of things I'd like is a smaller tensioner for 18 tooth at the back instead of having to get the longer versions. Or better yet an invincible tensioner. But I agree with larger bash rings. Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 24, 2011 Report Share Posted February 24, 2011 You can't really get a smaller tensioner for 18t-ish sprockets simply because you need to have an arm that'll extend from your hanger bolt to past the outside edge of your sprocket. You simply can't do that with a shorter arm. If you're having problems with that, just get a Trialtech tensioner. If you've got a different brand of tensioner with a locating pin on it, just get it off there. That way you can spin the longer arm further up, then use the sprung arm to get tension. It works really well and keeps things all neatly tucked out the way. Quite a lot of 24 riders use 22:XX because a lot of people still run 'Burns. I know of a few people running the Inspired 23t setup, and I'd imagine when the new 22t version drops that'll prove to be fairly popular too.

casualjoe Posted April 11, 2011 Report Share Posted April 11, 2011 18-15 does = 380mm stays though. If you've got vertical dropouts yes... Exactly, but this leaves you with 62mm of chain slop which is far from ideal. (Just done some maths for a new frame geo ) Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted April 11, 2011 Report Share Posted April 11, 2011 Supprised no one has said it yet.... Middleburn's with screw on threads magura hs33's lever body (2005), without the stupid bit that always breaks by the tpa, and with a split clamp design.

Revolver Posted April 11, 2011 Report Share Posted April 11, 2011 Tartybikes Adam had some special issue ones with threads, he found that there wasn't enough threads on there to safely take a sprocket or freewheel, and Middleburn don't want to spend money making new moulds just for screw on sprockets so it won't happen.

Well cant they manafacture one with more threads? I know pretty much anyone who runs a ffw would like to use middleburns, so theres definatly a market out there Quote Link to comment Share on other sites More sharing options...
Mark W Posted April 11, 2011 Report Share Posted April 11, 2011 They'd have to entirely change their setup to be able to do that, which would cost a shit-tonne and be a lot of hassle... Quote Link to comment Share on other sites More sharing options...
Scott Gibbs Posted April 11, 2011 Report Share Posted April 11, 2011 To be fair there is more than enough screw on cranks on the market to suit everyone from uber light comp riders to beasty street bashers! What trials needs is products that when you see it you think " how have we done without that!" I'd like to see Trialtech cranks in that oh so cool gunmetal grey colour and also white would be awesome. Quote Link to comment Share on other sites More sharing options...

I dont know the ins and outs of how middleburn manafacture their cranks, but for any new product they'd have to change their setup. Im sure they've got different setups for square taper, ISIS, 170mm, 175mm, ect. Im simply saying Middleburn have a reputation for their amazing cranks, and theres clearly trials riders out there that want them to produce a ffw crank......

Im simply saying Middleburn have a reputation for their amazing cranks, and theres clearly trials riders out there that want them to produce a ffw crank...... AFAIK they cast them and then machine them. So they'll probably cast two or three length of cranks, that's 3 moulds, and machine the sweet torque splines and ISIS or taper interface. The problem is the sweet torque spline area is too short, so you'd need a new mould (one for each length of crank) and then a new machining process, for the sake of a niche sport. Moulds are expensive. They could modify their exising ones (maybe) but that would be an ever so slight waste of metal, and a much more significant waste of time cutting the extra bit off for the rest of the cranks.

Luke Rainbird Posted April 11, 2011 Report Share Posted April 11, 2011 Im sure they've got different setups for square taper, ISIS, 170mm, 175mm, ect. Pretty sure that's just a case of running a different CNC program on the cranks which'll be cast by that point though? I could be wrong of course, but if that's the case then they'd have to cast a completely different set of cranks purely for the screw-on sets and that's where the big bucks come for relatively no gain on their part. Edit; Hot damn, it appears I was snaked. Quote Link to comment Share on other sites More sharing options...

Yeh i gathered they'd have to make a new mould, but considering all they'd have to do is have more material near the bb, and then cut a thread into that material.

Luke Rainbird Posted April 11, 2011 Report Share Posted April 11, 2011 It's still effectively a totally new product to produce though. Yes, they can get the CNC'd machining side of things done fairly simply on top of what's already available to them from their existing range, but the casting would be the bit that costs the big bucks really. Not so ideal. Quote Link to comment Share on other sites More sharing options...

Not so ideal. Not saying its not ideal, but it'd open their products up to a whole new market, i.e mod riders. Because most mod riders prefer a ffw setup.

Luke Rainbird Posted April 11, 2011 Report Share Posted April 11, 2011 Even if all the mod riders that fancied a set paid out for some though, that's a tiny market compared to pretty much the rest of the mountain biking world where their current clients lie. If it'd been worth their while to do it, they'd have done it by now Quote Link to comment Share on other sites More sharing options...
