It does not bother me so much but sure I can take your point that it is more fiddly. It would also be easier to lose a part if you need to do this out on the trail.
Anyway, I am not knocking the new option from Nimbus, just suggesting that I think that the URC is (in my opinion) just as good and cheaper.
To be honest, I am actually really pleased to see this new option from Nimbus. Previously they had the 26" and whilst I am very happy with my own 26", it has been mentioned numerous times here that the mountain bike market is increasingly favouring the 27.5" size and hence the tyre selection for muni is better there. Realistically muni is how most people who buy 26"/27.5" will use their machine.
With a steel 27.5" Nimbus, people who want an entry level machine have more tyre options and in addition those that simply favour steel have a great base to build up their dream uni from, given it has all the baseline parts needed to attach higher end components (ISIS hub, 27.5" wheelset, disk brake tabs). So this is a very nice new option and I am glad it has finally appeared.
