Answering your cycling questions

Hi, you would need 28" x 45mm for a comfortable fit, but a 28"x 35mm would work too, not as efficiecient (little latteral spray) but depends on how much splash you would like to stop. Also depends on which tyre your using, flat chunkies no good but semi road tyres with curved profile would be fine.

You need 45mm ones.

They will fit.

Yes, these should fit even with the hydraulic disc brakes.

Hi, no they will not if you have suspension front forks, the mounting points are wrong for the stays, rear mud gaurd will be fine. How ever if you have basic engineering skills they can be altered to fit by bending the supplied brackets through 90 degrees and cutting the stays to lenght, i can supply photos of an insall on my 2010 specialized crosstrail pro. They look good and work well!

50mm will be best for your bike.

Yes, they will.

Tyre clearance would be fine, but it doesn't look like there are any eyelets on the fork or by the dropouts to which the mudguards could be fixed. You might be better off looking at some which attach with cable ties.

Yes these should fit, you will need the thinner versions.

I assume you are talking about the sentinal 1.0? In which case it appears that there are eyelets to fix mudguards to properly. The clearances on the fork and rear stays should also be fine seeing as the 30mm ones are so narrow (they fit my trek 1.5, which is fairly tight). Clearance on the tyre shouldn't be a problem, due to the shoulderless design of the guards - 26mm tyres would leave 2mm either side anyway. Hope this helps!

Yes they are close fit mudgaurds classed as full length, However i would class them as 3/4 lenght as they are a tad shorter than normal but still give good water spray protection and look top dog on a hybrid bike!!
