[Closed] Truvative Hammer Schmidt

riddin it on a demo bike... only for a few runs... it was very good. makes for a good chain line. fast shifting and zero drag / feedback through the crank. not friction and the ground clearance is amazing.

strange being able to shift while not pedalling

waste of money and not yet necessary from my limited experience in the pyrenees.

It reall appeals to me. This year I ran a double bash/ring setup in Morzine and managed to get the chain jammed in between the inner ring and e-type mech on my old Scott 3 times.

I'm about to buy a Scott Gambler freeride and the Hammer Schmidt seems like the ideal addition.

as the lecht hinted at... it is very very expensive... 😯 so poss a waste of money...

a good chain device solves the probs...

I can get it at trade price+VAT through work, so quite a good buy for me! 😀

I have one on the bike I use for DH marathon racing. it is absolutely *amazing*. yes, there is a small weight disadvantage but I reckon this is offset by the extra clearance and the ease of shifting. you don't realise how bad front mechs really are until you've tried Hammerschmidt. There's no discernible extra friction either. Yes, it's expensive but you won't regret the purchase.

bullsh1t........it's a solution to a problem that doesn't exist + weight penalty FFS.

sram HS is krappo. full stop.

Limited experience and you're an authority on it!

aye - and you ? how many hours have you ridden it ?

Lecht, if my chain is getting caught bewtween my e-type mech and inner ring then it's offering a solution for me.

While YOU have no problem with a standard mech set up, I (& probably oher e-type mech users?) most certainly do. So, it's certainly not a solution to a problem that doesn't exist!

epic - confirmed and cleared your chainline / spacing ?

Done, several times. Fully set up by pro mechanic too. Just a common problem and design fault with e-type back plate spacing flex. We have a customer who has the exact same issue as me but on a different level e-type/different brand chainset/different frame. Specialized have now done away with the back plate BB mount for this very reason. 🙄

Have tried it. Wasn't overwhelmed by it by any stretch. Weight penalty, no choice of cranks....massive expense. Doesn't function much better if any than a traditional set up.

Maybe just the one I rode (imperfect setup perhaps) but it didn't live up to the hype - there was a noticeable delay in shifting on gradients or under loading and the shift was less than impressive. Also it felt a bit wooly for want of a better word.

As I see it the main benefit of it is ground clearance, but that hardly justifies the expense and, tbh that really only becomes a major issue on dh race bikes with low bb heights and masses of travel.

One ring to rule them all.

i have got many many many hours on one of these...would i buy at the current price compared to a front mech and a crankset...thats another matter

I cant help but think the real problem is the rear mech not the front. Thats the (ahem) real wink link in the system. Its got more to do, has to cope with greater forces, its exposed to all kinds of trail litter & one good wack & your indexing is out. A 2 ring drive chain is a pretty basic & relialble piece of kit as it - Im not convinced Truvativ have really come up with anything new here.

i have experience of truvativ cranks - they blow goats.
