  1. Probably the pinch bolt, try slackening it off a touch, also put a drop of oil on the brass bush and pivot Clean the rotor with surgical spirit/cellulose thinners to make sure its thoroughly degreased (try not to touch the braking surface with your fingers either). Take the pads out and cook them over a gas ring, rebed the brake and see if that helps, if not then get a new set of pads.
  2. Assuming you mean the barbed fittings, you need the clamp blocks (or some wood with a groove filed in the same size as the hose), alittle lube oil or washing up liquid work fine, a vice and a small hammer. Cut the tube completely straight with a sharp stanley knife or similar. Hold the tube in the vice using the clamps, leave about 5-10mm of tube sticking out the of the clamps. Put a drop of lube on the top of the tube, a tiny amount on the tip of the barb wont hurt either. Position the barb centrally in the end of the tube, make sure its perfectly straight and square. Gently tap it into the end of the tube with the hammer, be careful to keep it straight otherwise you may split the tube. If you split the tube or muller the end, simply cut the bit of tube back and try again. With any luck the barb will just slip into the tube Repeat for the other end. You have to cut the barb out of the tube, again a sharp stanley knife and watch them fingers!!!
  3. In my experience you will get blisters on any grips, theres only 1 thing to do and thats grow some good old hardened callouses and look after them Rubbing surgical spirit where blisters form hardens up the skin over time (makes you smell a bit funny though ) or just riding with gloves on will do the same. Once you have callouses formed just keep them smooth (I use a pumice stone to smooth mine if they start to crack). If you smooth them too thin then you will get a blister forming underneath the callous which defeats the object, if you leave them too thick they will eventually tear off and be painfull; moisturising also helps. Ideally you need a flexible pad of tough/thick skin where it rubs Personally I prefer ODI roughnecks as theyre thin, grippy and last forever, better with gloves though when new. If you prefer to ride without gloves then ODI longnecks are supremely comfortable. I tried foam grips and hated them, cut them off and threw them away lol, never seen the point in lock-on grips - just put rubber grips on with alittle petrol and they never move
  4. You can put a harsh grind on ANY rim, it might not last long (because the aluminium is a softer grade) but that is the same with any grind on a soft rim. The grind on my rear tryall goes dull pretty quickly, especially with hard pads - currently testing now with heatsink reds. I ran some rimjam greens on a fresh medium grind and they were half worn in 4 hours, I just put it down to bad compound as it had happened in isolated cases - never got the replacement set of pads to try as promised by chris - no matter though, its not like theyre expensive Oh and I bought them from tarty, under tartys recommendation for pads on a grind
  5. Its quite possible he hasnt got a clue about rims, for example I have a tryall rear and mavic xc717 - I think theyre both good rims but I dont know any different. If I were to need a new pair of rims I wouldnt have a clue as to what is recommended and generally considered 'the best' Without any additional information (selection criteria) it was a very stupid question though

    The crank threads will fail first, although if its crossthreaded the threads on the crank are already f**ked You could cut the freewheel off the cranks if its not budging. Take the lock ring and gubbins out of it, hold the crank arm in a vice, and grind a groove across the width of the freewheel inner - you dont want to go through the steel inner as that will really knacker the threads. When theres 2-3mm of steel left get a cold chisel and tap into the groove, with any luck the inner should crack and come free of the threads alittle I seem to remember something about deng cranks not being machined true and the freewheel wobbling about as the cranks turned, could it be that?

    Profile Hubs

    A decent quality large adjustable will do the trick, if not the careful application of a vice

    Profile Hubs

    Got a profile on my bmx and Im pretty sure you just undo the lockring with a big spanner & chainwhip. The sprockets are splined onto the cassette body (well it wouldnt be a cassette hub otherwise duh!). Pity you dont want to try a 16t as I have a spare one here
  9. You can repair the tpa at home, search the wiki, theres an article in there on it
  10. Have you read my post? Loctite is worthless unless you prepare it properly
  11. My square taper cranks never need tightening, not once in 4 years Im still reckoning on dead cranks, how tight do you call tight? When tightening my cranks using a long series 8mm allen key I reckon I put about 40-45kg into the allen key, that equates to about 60-70 Nm torque, not uber tight but it works. If youre going to use loctite then make sure you have the right grade for the job, thoroughly degrease both threads with a proper degreaser (not something like muc-off, more like MEK or cellulose thinners) apply the loctite and torque it up, leave it to set and go ride. Loctite will never stop a crank from wobbling if the taper/splines are knackered though. edit: reading that you have square taper, make sure that the taper isnt pulling too far through the cranks, its possible the taper was cut incorrectly.
  12. Cranks are f**ked and you dont know how to use loctite
  13. To get up on the higher stuff you just need to go faster and bunnyhop/tap up it, easier to learn on bigger stuff on a bmx because its easier to bunnyhop and fakie. The higher you land from the faster you have to fakie - love abubaccas on quarters the feeling of nailing the tyre on the face of the coping is ace
  14. Assuming you mean hopping onto the edge and coming off square and landing backwards? Thats an abubacca Once youre landed on the edge, you just need to pull off backwards - pull the bars back towards you and as they come up to above the bb/rear axle simply hop the rear wheel off using your body weight. Practise on curbs first and learn how to step off backwards without hurting yourself. Whilst youre in the air, going backwards you either need keep the front wheel up and land with the brake locked or let go of the rear brake and level the bike off so it lands with the back wheel just before the front. If your front wheel is too high when the back touches youre likely to go flying on your arse if your brake isnt locked. The action of doing the hop with your body weight should bring the back wheel up underneath you to level the bike off. Once youve touched down its either carry on hopping on the back wheel or learn to ride fakie, but thats another story......
  15. Got V8s on my trials bike, old shape V12s on my bmx and easton flatboys on my santa cruz, they eastons are by far the best pedals Ive used, alittle loathe to use 70 quid pedals on the trials bike though so Ill just keep with the dmrs IMHO you cant beat the original DXs (the reason I still have a set of old shape V12s on my standard) will certainly look at the mx30s for future pedal needs though
  16. Heatsink cnc reds on an echo hifi with an echo control booster works worse than without, more flex but way more bite and hold
  17. The way I true my wheels: - Get a zip tie and stick it round the fork leg/seat stay and cut the tail to a length that you can set so it touches the rim - I use the zip tie rather than the brake blocks because you can adjust it as much as you like, it can be set so that it just kisses the rim at the high spots so you can see which bits need pulling over I only use park spoke keys, whilst theyre more expensive theyre the most comfortable Ive used and they dont have a habit of mullering the nipples Always working from the valve hole in the same direction can keep things simpler. Tension each spoke in turn working round the wheel (I usually keep going until the the spoke thread is flush with the top of the nipple head but that depends on spoke lengths) Once you have done a complete wheel then check the spokes for tension, if theyre not tight enough then go round again and tighten them half turn at a time till the wheel is tight - with any luck this should make the wheel round If the wheel needs dishing (pulling over to one side) then loosen one spoke on the one side and tighen the next. eg: if the rim needs pulling to the left then you loosen the 1st spoke on the right hub flange by 1 turn and tighten the next spoke by 1 turn (should be on the left hub flange unless you spooned the lacing ) Once you have done the whole rim check it for dish again and repeat as necessary. If the wheel is egged and you know the rim is true its usually (in my experience) a lacing problem, check the spoke tensions and the amount of thread sticking though the nipple, also ensure the nipple is seated properly in the rim. Once youre happy with the rough dishing of the rim and its nominally central in the frame then you just need to get it straight - again in my experience if the spoke tensions are pretty even then it will be a straight build. Spin the wheel and note where the high spots are, set the zip tie so that it touches at the high spots only. Turn the wheel slowly until you hit a high spot and pull the rim over as you did when dishing, keep working round the wheel progressively closing down the tolerance on the zip tie and you will get a straight wheel. If you find the dishing comes slightly out of line whilst truing simply dish it over exactly as before. Once the wheel is straight, round and central you can give the spokes a final tension (or you may find that they will be pretty tight after truing) and just check it all. Finally before you put it back together it helps to stress relieve the spokes to help them bed in after tensioning - simply grab 2 sets of spokes where they cross over on the same side and squeeze them together along the lateral axis of the wheel, you should hear them ping as they settle against each other. Work your way around the wheel untill its stopped pinging, alternatively just go ride the f**ker and it will bed itself in Go ride for a bit, take a spoke key with you and check the wheel every so often, if you find a wobble on it then simply true it and retension the spokes
  18. Ive recently been suffering with graphical anomalies with my twin 7900 gs sli setup, most particularly in assassins creed and I tried everything to try and sort it with no joy Took one of the cards out to see if its likely to be heat related and all the problems have disssapeared As it is assassins creed runs maxed out on one 7900gs just fine so now I have a spare 7900gs, wanna buy one?
  19. Talk to a physio, they will be able to do what 99% of people here cant do - internet diagnosis for anything is never guaranteed Cortisone is a steroid medication that has good anti-inflammatory properties.
  20. On the trials bike its over the bars to pallet kiss - almost bit through my bottom lip in 3 places and it was bleeding for 4 days because every time I laughed/smiled/talked/ate etc it just opened the holes up On the bmx its either: - Over the bars to coping kiss (recurring theme there) on a miniramp - overnight stay in hospital with 4 days of concussion, amnesia for 2 weeks (still dont remember doing it) and loose front teeth for a while. or Deadsailor over the jumpbox at epic in brum - to tangled heap on the floor - to handlebars stuck into groin. Destroyed the plastic bar plug that was in the bars and proceeded to apple core 3" out of the top of my right thigh - a good chunk of flesh was left in the end of the bars when I kicked the bike away Another overnight stay, 5 stiches to close the hole up and another 4 to seal the top - an inch to the left and no more kids for me, 2mm to the right and no more me as they could see my femoral artery in the bottom of the hole Its really cool to be sitting in a pool of youre own blood though
  21. Doesnt sound like tennis elbow as that affect the tendons on the outside of the elbow. I suffered from tendonitis in my fingers years ago when I was riding bmx all the time, would get burning sensations in my fingers and eventually they would cramp up and I couldnt let go of the bars; not suffered from it much recently but Ive had a 2-3 year break from riding all the time. Could it be a trapped nerve in your elbow? In my experience that tends to be a shooting pain rather than a throb like tendonitis, also dont forget that your funnybone is in your elbow (just a big bundle of nerves that is exposed on the inside/back so it hurts when you hit it).
  22. Practise practise practise Learn to be looser and more relaxed on the bike and how to step off the bike when you need to bail, trashzen has everything you need to know about the basics. A well set up brake that you can rely on and trust to hold you is a massive confidence booster, so is a grippy big tyre on the back as it gives you a larger contact patch to balance on.
