thanks staind, eto pala yun, para palang SRAM yung shifter nya warlock, gaano kaya ka bigat yun? with a weight penalty, bagay siguro to sa mga downhill bikes...but would like to see this gadget myself

i think it'll be lighter overall but i'm only guessing. wala na kasing F-R ders., less 1 shifter, less cogset, less 2 chainrings and all the bolts, etc. accompanied with it, etc., etc. you get the picture. and it looks cleaner. check out that the Van Dessel Buzzbomb in gulli's pic (with the orange paint)! major plus (and selling point) is there are no overlapping gears unlike the conventional gearing system. plus it can keep up with both MTBs and roadies! and it's virtually maintenance-free. users swear by them. the big problem is the price!!! sub-$1,000!!! yikes! XTR na yun! sana XT price range man lang.

Yep true, the mechanism itself is heavy but without the other component you mentioned, this will lighten the bike enough. Said to be comparable with 27 speed MTB, with no derailer problems, mis shifts & chainsuck ;D see link below of Cannondale HT with Rohloff (w/ detailed pics) forums.mtbr.com/showthread.php?t=26900Yeah the price is painful, specially now that the Euro is strong, Cambia list em for $1099. Ano yan Staind? X-Caliber with Rohloff? Tama na...nde ko nagagamit ang derailers ko

excerpts from MBAction inquiry ;D
Q. In the March 2000 issue of MBA, the article about the Rohloff Speedhub stated that the weight penalty respect to XTR components was 5.3oz (130gr), which I thought was a bit optimistic, based on the declared weight of 1822gr for the Speedhub. Now, October 2001 issue, the article about the Jericho Leadfoot stated that the weight penalty respect to a "conventional drivetrain" is 3 pounds (1360gr). I think it's a bit pessimistic, based on the declare weight of 1972gr of the disc brake version. This weight is for hub plus shifter, without chain tensioner, as in the Jericho setup. It replaces a rear (disc) hub, cassette, front and rear derailleur, middle and smaller chainring (with five bolts), and two shifters, plus it shortens spokes and chain. The XT components it replaces weigh 1578gr (I've summed up Shimano declare weights, hub without 67gr of quick release, plus 60gr for shorter chain and spokes, plus 110gr for two chainrings and bolts). So the difference it's near 400gr, plus the additional weight of the eccentric-mounted bottom bracket (not the Rohloff-reccomended setup, though). Now I'm asking you: are the declared weights for the Speedhub real? What's up with that weight difference between 3/2000 and 10/2001? Thanks Claudio claudio.bosticco@tilab.com - 9/26/2001 12:36:39 AM
A. Claudio, I am not sure about the weight difference between the disc brake and standard version of the Speedhub. I'll have to look into the way in which we compared the weight differences. Although the Rohloff hub is heavy, so is the total weight of the derailleur bike's alternative list: the derailleurs, cables, housings, the left-side shifter, two chainrings/with hardware, the rear hub, its cogs, and the extra chain that is no longer needed. I'll need some time to compare apples to apples. RC

14 gears lang yung Speedhub although it covers the same gear range as the 27-speed derailleur.
Comment ko lang with the Speedhub is one at a time yung gear selection because of the single grip shift. There are instances when the change in gear ratios need to be large (e.g. sudden uphill/downhill transitions and you need to maintain momentum for the next uphill). That's when having a second shifter (for the front der) is better.
Parang sequential vs. direct access? As in cassette tape vs. CD? ;D ;D ;D

definitely a gadget worth trying, esp with the pros and cons stated here.
as for Truvativ vs. Shimano Hollowtech? i thought Truvativ was Russian for "noisy and clunky" hehehe ;D ;D ;D

Other manufacturers like Gazelle and Batavus have been producing touring and commuting bikes with internal (planetary) gears for years. They're very popular in the Netherlands and in Japan. Some of the "surplus" bikes from Japan you find at ukay-ukays and garage sales come equipped with 3 or 7-speed planetary hubs.

That speedhub looks nice although parang masyadong complicated, And i thought bicycles wr to be made simple and easy to maintain. hehehe
Truvativ vs hollowtech of shimano?
GO TRUVATIV!!!!
Truvativ according to Mr. Webster means
" EXcellent product, the choice of maxbuwaya"

"Dubious product, hence it's the choice of maxbuwaya" j/k!

agree with staind, definitely less maintenance tong mga hubs na to truvative? sa OXFORD naman, nakalagay..."cold war term for ornamental crankset used to attract cold war babes...the choice of poseur cold war playboys"...hence the choice of guys like maxbuwaya....james bond used shimanos ;D ;D ;D joke-joke! ;D

Maybe a big chunk of the price can be dropped if it were to be assembled elsewhere. German craftmanship is indeed expensive. Even just Rohloff chains are expensive. But times have changed and companies need to be competitive (ex: some BMW cars are assembled in Thailand). There's still some hope that we may experience speedhubs or something like it.
Or maybe someday the Japanese will take these apart and develop their own versions.

Actually Shimano have their own version which is widely fitted on touring Bikes, the Shimano Nexus...it comes in different speed settings. But nobody yet equalled Rohloff's performance. Here's an interesting link about Nexus in Sheldbrown site. *LINK*
