  1. How are you measuring 0.75? If via the typical chain checkers that stretch the chain between fixed points then be aware these tend to overestimate wear. My Parktools 10spd model (cc-3?) Reads 0.75% when actual wear measured with an accurate 1000mm steel rule is 0.25 In this case however you clearly have worn the chainrings as well as cassette and chain beyound re-use. My chainrings usually last quite a bit longer than my cassettes and I usually get at least two chains through a cassette before replacing it. To extend life of your new drivetrain, buy 2 or 3 chains and change them monthly in sequence. This way they all wear in together and you dont get the big difference in spacing that is causing slippage for you now with a new chain on worn chainring. wash, dry and lube each chain when you take it off to store it. I prefer to wash them in a mild solvent like paraffin because this does not prevent lube from seeping into the rollers after cleaning. If you use water based detergents, Any water remaining in the links will take days to dry out and may repel fresh lube unless the chain is totally dried out beforehand.
  2. Innovative. Can't help feeling that whole frame would be miles stiffer if they just extended the divot in the seat tube to brace against the down tube....and mount the bottle holder on top.

    Maltodextrin

    Most sugars are potentially explosive if they are allowed to form dust clouds. Same goes for flour in mills and bakeries. This requires explosion proofed lighting and electrical equipment as well as other precautions. For home use on small scale you are not likely to be doing mass pouring, grinding or pneumatic conveying of dry solids so don't worry. Work slowly and in small quantities and avoid forming dust clouds containing the substance near electrical equipment or non-conductive surfaces (plastics) where static could build up and cause sparks..... Post pics if you lose ur eyebrows... [emoji95] [emoji102]
  4. To test rear wheel and hub bearings.... - Remove chain but leave wheel clamped in the dropouts. - Spin wheel. Should be completely smooth and silent. A rumbling sound means wheel bearings are worn. - hold wheel and spin cassette in reverse. Rough or rumbling sound other than clicking of pawls indicates worn freehub bearings. Any free-play or side to side play in the cassette also indicates possible bearing issue.
  5. Usually not worth very much but can be nice if you clean them up and put them in a glass display cabinet....if you go for that type of thing.
  6. Looks like northern Drakensberg to me. The prominent peak is the Eastern Buttress of the Amphitheatre....so I'm guessing its somewhere on the All-Out Adventures trails above The Cavern. Home territory for a TBLT. Mine's been there too. Also running 34t NW edit....Aaargh...Dean answered while I was typing...
  7. That new fork cost half of what you paid for the whole bike....unless it was a warranty replacement with pay in for the upgrade.
  8. Very happy eith my PCS 10. Not cheap but as long as bikes can be held by a clamp it will never need to be replaced .
  9. None of the tests should take longer than 2 or 3 days for a result but in fairness to riders it should be done in an accredited laboratory and these are not portable or cheap. Proper chain of custody needs to be preserved for both samples and results but this should not add more than a few days. I don't think we are ever likely to see on-site same-day testing for such a long and complex list of substances. Quite complicated instrumentation is required together with complex preparation and quality control procedures. You would also find that multiple lab techs are required for such a range of analyses.....rare to find all that expertise in one person. The months/years of delay that we are seeing are not attributable solely to laboratory issues though.
  10. Somewhere in the process there are long delays that do not serve the cyclists whose racing and registration fees ultimately fund these organisations. From sample collection on race day to SAIDS to UCI to CSA or whatever, substantial delays are occurring. These delays prejudice both the guilty parties and the compliant cyclists that should be earning the podiums and all that goes with that. Even if you will never step on a podium these delays even ultimately affect your seeding at your next race because the authorities are not timeously removing cyclists who should not be competing. I understand that hearings are involved and that the accused have the right to respond and explain but why not suspend a cyclist's competition license as soon as an adverse result occurs so that the rest of us can compete fairly while they sort their issues out. If the investigation results in no sanction, the cyclist's license is re-instated - he/she ony loses out on a few events that occurred while the investigation was underway.
  11. The explanation leaves me reasonably certain that there was no attempt to cheat here. But rules are rules and a rider competing at high level should make an effort to get to know them. But there are other guilty parties here.......guilty perhaps of an uncaring attitude and not nurturing our sport as we would expect them to. CSA could have included in its public statement that no evidence of an intent to cheat was found, simply that the penalty was administrative for failing to follow the rules....instead they made a very minimal statement that hid their own ( and SAIDS) shortcomings and allowed her reputation to be trashed in public. The reason I say there were shortcomings are multiple: 1) the athlete disclosed the use of prescription medicine when tested....multiple times.... but wasn't ever advised of the correct procedure or assisted with it? 2) so much time went by between testing and discilinary action that the athlete continued to compete in good faith, racking up podiums and prize money to the extent that she is now much more embarrassed by events than was necessary. This administrative negligence was also detrimental to other cyclists that followed all the rules. Why culdn't they have suspended her after the first declaration of using a listed substance without a TUE and helped her to get it sorted. 3) announcing the ban after its period has already elapsed shows that serious administrative deficiencies exist and yet no acknowledgment of this in a statement, nor any public commitment to improve the administrative rules that allowed this to happen. These authorities are mandated by their members to govern the sport on our behalf and we pay fees for this service. As such they are answerable to their members (us) when they fail. Hiding does not cut it with me. I think cyclists deserve better treatment.
  12. Even as a chemical engineer some of the names on that list make no sense or are unpronounceable to me...... How a person not educated in the sciences or backed up by a team physician is supposed to make practical use of that list I don't know. Even a simple common over-the-counter flu-cold remedy like Corenza that my GP advised me to buy yesterday has a few of those substances in it. So technically I'm a doper today but don't worry, I'm not entered for any races in the near future...... I would agree that the list should be supplemented by trade nemes and a stamp or approval mark on the packaging of medication saying 'safe-for-sportspeople' or the like would be very helpful.
  13. I really think the bike will be just fine running both wheelsizes with a 150mm fork. In terms of geometry we are talking only 2 or 3mm difference in BB height and a tiny diff in head angle too. Provided you flip the chip.....The owner of the particular bike in the pics looks to be running even more than 150mm fork and he kinda knows his stuff [emoji57]
  14. Most will spec the 150 fork if they want to run both wheel sizes. No problem. The bike in the shop has a Fox 36 Factory fork on it and looks like 160mm ,cos much more stanchion sticking out than the 140 fork on my LT
  15. Eyeballed it today. Awesome bike. I think I want one. They've been hiding it in the back room since November!
  16. Spez GC, not as durable but miles better. But it would send a mixed message if they display the latest SC with Spez tyres on......
  17. Guess where I'm going tomo? That looks like Fox suspension and XTR crank - so not the SC factory build. Not a huge fan of the Ardent at rear tho 'cos I know my TBLT corners, rolls and brakes a whole lot better with a rival brand....
  18. One, inside the frame below the shock.You can have a bottle mounted even with a piggyback shock. The TBLT had the mounts on the downtube below the front triangle.....so the bottle's mouthpiece always gets covered in crud from your tyres and you nearly fall off the bike when leaning down so far to get it out.
  19. Disagree. Same niche just better.
  20. Between this and the 5010 they got 130-135mm trail bikes all wrapped up. I don't see a new Tallboy LT as well. This one has the same shock layout as TBLT...but obviously revised with new geo and links. Big plus = water bottle mount inside frame at last Hightower is also 1x specific which I don't like but if the new 12 spd groups come in with 5x cassette range then current 2x and 3x have nothing to offer anymore so its OK. Myles will like the new longer top tube 'cos the bike can take a short stem now [emoji12] . The TBLT was quite short and felt a bit crowded for me with a short stem so I went back to the standard 70mm.
  21. So this is the new Tallboy LT. Very much like the option of 27.5+ or 29.
  22. Curious about what was shown on the pic that won't load in OP's post...... Oh ok I see....very old thread
  23. You can try spacing the chainring to give chainline on 4th largest gear at the back. If this doesnt solve ur problem then chainline not the issue. Look carefully at chain lube, alignment of RD. If your chain is worn less than 1% and the cassette not skipping teeth under power then you dont need a new cassette yet. Would be so much easier to advise if I could see the bike...[emoji3]
  24. Ardents drift a little when you lean them over but roll quite nicely. Never got fully confident on them. Spez. Ground Control rolls easier and grips way better. For a front tyre, Spez Purgatory even more grippy and not noticeably more draggy. I changed my half used Ardents for the Spez GC/Purg combo about a year ago and not going back. The GC at rear is quite worn now. Already bought another to replace it in preference to refitting the Ardents. I ride mostly trails. Definitely go for higher volume if you ride a lot of trail.
  25. Looks OK.
