Fixie tyres

fluff.

Apolgies if this has been asked recently but I can't find anything in search. Anyway, anyone have any recommendations for a rear wheel tyre for a fixed? I seem to be developing an alarming amount of slippage with mine, when starting off or standing on the pedals, even in the dry.

I was originally using a conti ultragator, but it's wet weather performance was rather scary, so I changed to a something not too expensive from the LBS (the mark ups on decent tyres were stupidly large), which turned out to be a Bontrager Select something or other. Didn't notice any problems till recently, and now I'm slipping on a regular basis (rechecked chain tension, tightened track nuts etc). So I think I need a something a bit grippier?

I've been using Specialized All Conditions for a year and a bit now. I've not had any unintentional slipping.

Rear wheel slipping, especially on hills, is usually caused by too much power and weight going through the back wheel - it happens more if you use a large gear, or if you pedal fast. You could try turning the pedals more slowly when setting off, with your body weight as far forward as you can (as near as possible to being over the front wheel if you're out the saddle) or run a smaller gear.

Panaracer stradius sport TG. Cheap, grippy, tough.

Hm, running 46x16 I guess that's quite a high gear (around 75"?) but it's fairly flat where I am .. the other side of the hub is 15 so that's no use

Will check out those tyres too ta, can get them at a not too distant bike shop for 12 a go.

i've never heard of wheel slipping like this. maybe off road, or on a path that has some moss growing, or maybe even in the wet. if its slipping in the wet, i can only think the tyres are very poor.
Are you sure its definetly the wheel thats slipping, its not just the sprocket thats turning on the hub, maybe cased by stripped threads.

Blonde, surely putting your weight forward will cause the rear to slip more, i'd have thought you want to put the weight over the rear.

i use contis. they do slip in the wet, on drain covers, white lines etc, & ive ended up on my arse a couple of times this wet, wet year. But I rarely feel the back wheel lose traction unless im on a drain cover etc, & id be a bit surprised if this is a tyre issue. i also dont think leaning over the front wheel would help- thats how you slip it deliberatley if you want to. and its a LOW gear that delivers more power to the wheel, easily demonstrated in a car......

i suppose you may have a very exceptional power to weight ratio- are you are a hill climbing champ or something?

hey, look at that, it doesnt let you write arse, it turns it into ars* instead..... :roll:

Some mistake shurely? Too much power yes, but too much weight, no! Friction - grip - is proportionate to weight. To increase grip on the back, put your weight back, not forward!

hm after having a closer look, the lockring on the drive side was only finger-tight, that can't be good can it? And I'm ordinary bloke sized with ordinary bloke power so it's not huge amouts of torque I generate.
