• Cheers Jim...just on train on way to the sticks. I'll look into them and get back to you. Ive got nothing against Tiagra...have had many a bike with that groupset in the past. Just want to check that theyre not stupidly heavy before commiting.

    The deep profile set you sold me are great for flats and TT but I just cant handle them on climbs. As long as mach1 +tiagra is lighter than novatech + r700 then I'm very interested. Will be spending a lot of time in the hills in the new year.

    Ill email you when I have had a chance to do some sums.
