  • Can someone tell me how you get a SS cog onto an mtb hub without it digging the hell out of an ally hope cassette body?

  • ^^ there was a discussion about this on the fairly light pomp thread - you need one with a nice wide base, i.e. Gusset double 6

    edit - beaten to it.

    Hope freehubs are known for this TBH. A wider cog would help.

    These are proper nice, and stainless steel. Have a couple myself.

  • Have we discussed 650b vs 29er on here yet?

    Someone on MTBR summed this up brilliantly for me.

    'wow look at those fecking cool big 29er wheels.......bit too big maybe.......I'm not sure.....26" is perhaps boring or outdated.........oh a fence sitter option....yes please'

    Its no wonder the industry loves them.

    26 v 29 is hardly a massive difference. The pros and cons of each even out. Why we need a middle option is beyond me.

    (I'm only bitter cuz the industry should be investing producing cheaper fat components)

  • ^^ Flash cog.

    I get on well with the Andel ones myself. http://www.velosolo.co.uk/andelss.html

  • 29er wheels are almost big enough ;-)

    I'd like somewhere between 30-33

  • 29 rear 36 front?

  • Superstar components do a pretty cheap wide base cog

  • ^ I nearly read that as wide ass cog.

    These look ace. Perfect for 8sp chains (and running a couple of these).

    Chris King and Niner make things similar but for a lot more cash.

  • If we're talking sprocket porn...

    Have it on my cargo bike. Its an important interface between heavy as feck bike, and expensive IGH.

    My plastic belt cog has yet to even smudge my Hope freehub.

    That would be fair enough, if the increase made it worth for you giant freaks. My 2.55 Weirwolfs are nearly 30", I guess the bigg RRs are similar, and the krampus wheels are 30.7"

    I'm 5'7" and SS 29er handles fine. The big wheels work well for this set-up for my taste. If I was to go with suspension, I would'nt hessitate to grab some 26" wheels. I simply cant see why you'd need something inbetween. Whats next 675s for those 650 - 29er fence sitters?

    They'er real nice, and far cheaper than other stainless bling.

    I love the look of these..

    I have a few chainrings from this guy. Very nicely made, and great service.

  • ^ Ti?

    Yeah, Boone Ti. I've got a feeling they're not made anymore, and are very expensive.

  • 26 v 29 is hardly a massive difference. The pros and cons of each even out. Why we need a middle option is beyond me.

    If we take your statement at face value, you have made the case for 650b. If we assume that on a graph of x=wheel diameter and y=arbitrary measure of "faster" and f(x)=y, you're saying f(26)=f(29). Taking it as read that f(24)f(26) and obviously also f(27.5)>f(29)

    tl;dr
    If 26 and 29 are equally fast and bigger or smaller wheels are slower, 27.5 is almost certainly faster than either 26 or 29.

  • This is why I no longer use the trail at Cwmcarn.

  • Is Twrch shit then? I haven't been, only been to Afan really, which isn't bad, but very clearly man-made. Not enough rooty bits or drops etc. The new bike park bit is as smooth as a BMX track, which is a bit lame imo.

  • I find the Twrch pretty good, albeit I didn't see it in its previous guise. When I can get round without hurting myself i'll consider myself awesome at bicycling.

  • It used to be really good 5-6yrs ago before it started getting busy. So many corners have been straightlined and there are massive braking bumps so you can't take any speed into a corner. There are a few sections that not many people ride which have been there for 10yrs+ which are still great. I tend to ride off into the hills and link up to a good bit at the top. Nowhere near as technical but much more pleasant.

  • Does not that nonsense rely on a rather narrow TTer's assumption that better equals faster equals better.

    I seen a photo of tester: He didn't look very narrow ;-)

    igmc

  • Does not that nonsense rely on a rather narrow TTer's assumption that better equals faster equals better.

    It's not nonsense (unless you have a critique of the maths, in which case bring it), and you can substitute whatever performance parameter you like in place of faster; obviously I'm a racer so faster=better, but Smallfurry wasn't prescriptive, he said all the pros and cons cancelled out regardless of which performance measure you use

  • Where did smallfury say "*regardless of which performance measure you use". *

    He didn't, but it was implied because he failed to state under which performance measure the pros and cons exactly balanced out, therefore he must have meant they were in perfect balance for any relevant output measure.

    Anyway, stop taking it so seriously; he made a statement which lent itself to a bit of piss taking, that's all. By analogy with his argument, I might say that since I can do 25mph on my local TT course on either a 90" gear or 110" gear, there is no point in trying any ratio between those two.

  • "All maths that I don't understand is nonsense. FACT."

    It's because you don't understand maths that you failed to see the humour in my first post in this discussion.
