Several weeks into the Sanderson Blitz and I'm well pleased. I have put a full length outer wire to the rear mech. For some unknown reason the gear change was stiff using the routing provided. I had a similar problem on a 98 Kona Explosif and solved that in the same way.
When I wrote about the Blitz being slow I think I was suffering from a combination of the change to 2.35 tyres from 2.1, and not having the seat high enough for me. My knees began to tell me to bring the saddle up a bit and now I have, my knees are behaving and the power input/acceleration seems better.
I visited the Leith Hill area for the first time in a while and took the Blitz along various of the trails there ( including the Yoghurt Pot, new to me, thanks to the similarly-aged-geezer who showed me it...enjoyed it) and I'm pleased with how poised the bike is. Sudden ups or downs or twists and drops don't faze it at all, and it has muscle and presence if you take dodgy line choices.
Climbing in the 140 setting on the Talas fork is no problem even on steep stuff. I did an experiment on the South Downes climbing all the stock tracks up the northern slopes between Itford (R Ouse/Lewes)and Alfriston when they were frozen up, pre the bad snow, and it managed the lot in 140. It does obviously help knocking it down to 100 or 120 which plants the front end down even firmer.
It'd be interesting to see what a professional bike tester had to say about the bike. So far I'm thinking that the Blitz is better than my On One 456 or my 303 Pace. I guess you can say that it isn't a race whippet and possibly you could say that proficiency is boring but it'll do for me and I wouldn't hesitate to recommend it.
...............and thanks to Takisawa2 for making up for my abscence of tech know-how and posting my piccies of the bike on a seperate post on this site.
