As far as the delivery and service are concerned it was straight forward . I didn't order until 9:25 pm so didn't expect next day delivery but they arrived a day later which is fine. This compares well with most cycling sites but internet service is becoming so good these days that to be classed as very good you need to offer tracking(DPD are an excellent courier as far as this is concerned) and /or delivery time slots (at extra cost, ofcourse). For those at work a time slot can mean saving a lot of money not having to take time off to accept the parcel. If you've got a neighbour who can accept the parcel then you don't need that extra service, but the very good sites -not necessarily cycling sites - do offer this option these days. I hasten to add that compared with most other cycling sites the service compares well on this my only order so far. I bought Stan's Doc Blue Sealant and some Schwalbe Easy Fit Fluid. This stuff is very hard to find anywhere so this is a plus in itself. However, I couldn't find any Schwalbe Ultremo ZX tubeless tyres here. I don't need them right now as I've had these tyres on my bike last year and just needed to dismount them, clean up, and add some new sealant ready for the coming year. But I will need to buy some before too long. The sealant is priced well but the easing fluid, at £6.49 for a tiny can(seemed to be a large can judging from the illustration at this site), seems over the top. At the moment there is only one site in the UK selling these tyres , at least as far as I can see, and that is as a pair of tyres with sealant and the same small can of easing fluid so it works out quite expensive at £119 a pair. I have found them to be excellent tyres and it would be nice to see nextdaytyres selling them singly at a better price, without sealant and easing fluid included, just like any other tyre. It should then be possible to sell them quite a bit cheaper. They would definitely have me as a customer.
