Heatsink Posted June 26, 2015 Report Share Posted June 26, 2015 Dear all, There are 10s of UCI bashrings on the market and the difference between these is mostly about styling preferences, weight and price. I was wondering if there are any needs being un met which could allow some innovation to come in? I've been considering releasing a UCI bashring for a while, but it's been a lower priority whilst there are innovative products to be working on like chain tensioners. Maybe there's something I can incorporate in to re-engergise the design with a unique selling point innovation? As always, thanks in advance for sharing your ideas and experiences!

AdamR28 Posted June 26, 2015 Report Share Posted June 26, 2015 From my point of view... there are already way too many! Can't think of any innovations you could realistically bring in, obviously Milky Way tried with the Gummy but it was just too expensive / heavy. 2 Quote Link to comment Share on other sites More sharing options...
N.Wood Posted June 26, 2015 Report Share Posted June 26, 2015 If you do make one, put a lip in it so when you tighten the freewheel onto the crank it doesnt spin round and end up in the wrong place, a la Try-All Symetrik and probably some others. 3 Quote Link to comment Share on other sites More sharing options...

DAMON WATSON. Posted June 26, 2015 Report Share Posted June 26, 2015 lip as said above so when cranks tighten it doesnt spin, hugely annoying 1 Quote Link to comment Share on other sites More sharing options...
SCOTTY___ Posted June 26, 2015 Report Share Posted June 26, 2015 Something that is actually designed to sit against the BB cups under the frame instead of on the cranks? 1 Quote Link to comment Share on other sites More sharing options...
Heatsink Posted June 26, 2015 Author Report Share Posted June 26, 2015 Something that is actually designed to sit against the BB cups under the frame instead of on the cranks? Here's the Milkyway Gummy bashring from 2011 fitted on both the crank and the BB. I'm wondering what stops the majority of 5mm wide bashrings from being mounted on the BB?

Mark W Posted June 26, 2015 Report Share Posted June 26, 2015 Reducing the thread contact between BB and frame would probably be one of the reasons I'd imagine? Non-drive crank clearance might play a part too. In terms of lip vs. no lip, there is another way - Bonz used to (and still might) do a bashring that just had two 'knobbles' that stopped the bashring from spinning around, depending on which foot forward you were. I didn't really agree with the positioning of them (in that they meant that the bashring sat at a weird angle), but that style could still work and would theoretically be lighter than having to make a stepped bashring. 1 Quote Link to comment Share on other sites More sharing options...

Heatsink Posted June 26, 2015 Author Report Share Posted June 26, 2015 Cheers Mark! Just been googling for such a bashring but no joy yet!

MartMini Posted June 26, 2015 Report Share Posted June 26, 2015 the try all symetric was a pretty good design for the 'anti-rotation'. I just found the gap slightly too small though, and had to file a bit off my cranks 1 Quote Link to comment Share on other sites More sharing options...
Mark W Posted June 26, 2015 Report Share Posted June 26, 2015 The lip in the later editions also provided a convenient fold line for the bashring if you hit them hard But yeah, as Ads said, the lack of uniformity isn't ideal. Just create a knurled finish on the section of the bash that contacts the crank and freewheel and be done with it 1 Quote Link to comment Share on other sites More sharing options...
MartMini Posted June 26, 2015 Report Share Posted June 26, 2015 the only thing about the symetric was the freewheel 'lip' was so thin, that mine basically bent inwards, locking the bashring onto the cranks. In the end i filled the lip off, and just used a 1.5mm bb spacer to hold the freewheel away from the bashring 1 Quote Link to comment Share on other sites More sharing options...

Ali C Posted June 26, 2015 Report Share Posted June 26, 2015 I'd like to see cranks come with an integrated bash guard, one that flows in nicely and protects both sides just enough. Most trials parts seem pretty disposable so it's not the end of the world if it gets destroyed, but if it's designed right it should last anyway. Not sure how initiative a simple bash can be, maybe something with a rubber outer edge so it doesn't smash up walls? Would mean it's harder for observers to hear in comps (it's often easier to hear the bash hit than actually see it). Quote Link to comment Share on other sites More sharing options...
SamKidney Posted June 26, 2015 Report Share Posted June 26, 2015 Can't go wrong with a full ring bash. They're stronger and you can't get them in the wrong place. All round protection can only be a good thing. 1 Quote Link to comment Share on other sites More sharing options...

Maybe with a series of holes where you can put in a pin to get the desired location? It's a nice idea to stop it spinning but not really to difficult to get it where you need if you fit it in the vice and tighten the freewheel up before the cranks installed ? 1 Quote Link to comment Share on other sites More sharing options...
bing Posted June 28, 2015 Report Share Posted June 28, 2015 The cranks on my crewkerz have a pin in them that the bashing locks onto so it can't rotate. It's switchable between left and right foot forward as well Quote Link to comment Share on other sites More sharing options...
ogre Posted June 29, 2015 Report Share Posted June 29, 2015 full rings are where it's at, no worrying about your set up if someone who's not the same footing as you has a razz on your bike or you have a cockup that isn't 'normal' that said the jazz bash ring had plenty of holes i wondered if you could put a bolt in it while you tightened it up to it stayed in place. OR why don't you look to make a bash that's specific for certain cranks like the TT SLs i'm tarty enough to want a product made specifically for something i already run; i bet i'm not alone in that. 1 Quote Link to comment Share on other sites More sharing options...

I thought about that after I'd posted actually - does make a lot of sense. Maybe with an eccentric boss so you can get a good range of adjustment, rather than just 1 or 2 positions. Agreed about the second point too, but something I often forget as well is that many people don't have easy access to some of the tools we're lucky enough to be able to use whenever we want. 1 Quote Link to comment Share on other sites More sharing options...
